(II) major new products and application scenarios during the reporting period
1. Intelligent well pad integrated solution
At present, no matter in the oil field or in other fields, all products are developing towards integration and intelligence, which is not only to control the cost, but also to reduce the difficulty of product maintenance. More importantly, it can let users experience the intelligence of products and let maintenance personnel truly experience the convenience and efficiency of products in use.
The upgraded intelligent well pad integrated RTU has the characteristics of Internet of things and interconnection of all things. The following means are used to connect all equipment in the well pad: the voltage output of the power supply unit of the equipment box is collected and diagnosed by AI analog quantity. The intelligent network management switch is connected and accessed by wire. The oil wells, water source wells, valve groups and third-party equipment in the well pad can be connected through wireless equipment and wired equipment. The field staff of the well pad can access the well pad data and configure the parameters of the intelligent well pad integrated RTU through wired connection and wireless connection. Workers in the operation area can access the data and configure parameters of the well pad through wired connection. The scheme integrated network management switch has VLAN division function, which can realize the isolation of video stream and data stream in the well pad, and provide more detailed data division and isolation on the basis of production network / office network isolation. 2. PLC control scheme of unattended station
Small stations are unattended and large stations are unattended, which is an important goal of oilfield digital management upgrading.
As the main station of the oilfield station, the booster station undertakes the functions of crude oil collection, oil and gas buffer, export booster, crude oil heating and so on. As a process control automation system, the basic requirements of the booster station control system are that the process parameters in the booster station operate within a reasonable range and the crude oil is smoothly transported to the downstream station. After the transformation, the unattended station has the emergency switching function of some processes. One patrol officer will be stationed at the site of the station. At ordinary times, he does not participate in the operation of the facilities in the station, but only carries out daily patrol inspection and fault treatment in emergency state.
In order to further improve the safe operation level of the unattended station, under the unattended operation mode, the PLC control program of the unattended station needs to fully consider the fault handling function of the station under various abnormal conditions. Therefore, in addition to the scheme control requirements designed by the Design Institute, the following control logic is added: ① alarm diagnosis of key process parameters. In addition to the monitoring staff being able to timely find the abnormal alarm of on-site process parameters through the monitoring platform, the on-site staff should also be able to timely understand the abnormal process conditions in the station through simple audible and visual alarm. ② The diagnosis and analysis function of production equipment and the remote unattended operation of unattended station are mainly guaranteed by various process instruments and equipment on site. PLC shall also complete the diagnosis and analysis function of key equipment. ③ The off-line diagnosis function of PLC equipment can timely remind the resident staff to strengthen the inspection of process facilities in the station, and strengthen the communication and coordination with SCADA monitoring platform.
3. Digital scheme of water shutoff and profile control
In order to improve oil recovery and achieve the purpose of increasing and stabilizing production, the oilfield invests huge human and material resources for water plugging and profile control every year. However, the workload of water plugging and profile control is huge, the number of construction teams is large, the construction fluidity of profile control site is large, the on-site management and supervision of profile control and water plugging are difficult and the efficiency is low. According to the requirements of “standardized design and modular construction” of the oilfield, the design is based on the concept of ensuring monitoring demand, reducing transformation cost and advanced and reliable scheme. The important production parameters in the construction process are monitored in real time, and the data acquisition and video storage server and special monitoring website are built based on the digital information platform. At the same time, the production monitoring of water shutoff and profile control is connected to the SCADA system platform, Realize real-time monitoring of operation process.
4. Near bit geological guidance system
The conventional MWD system can not meet the technical service needs of ultra-thin reservoir drilling because the measuring points of formation data are far from the bottom of the well and the measurement information is relatively lagging. Only the near bit MWD instrument can effectively improve the penetration rate of ultra-thin reservoir. Near bit geological guidance system is an indispensable tool for drilling horizontal wells in ultra-thin reservoirs.
The technical difficulties of near bit tools lie in the wireless cross transmission technology in the complex and changeable formation and the accurate azimuth measurement technology under high-speed rotation and violent vibration. After years of continuous testing and technical improvement, Zetian Shenghai, a subsidiary of the company, has successively launched wireless cross transmission schemes of different technical routes, which can realize stable cross transmission of communication in the environment of oil-based mud and high conductivity water-based mud, and the technology is industry-leading. Azimuth gamma measurement realizes the breakthrough from azimuth gamma in four directions to multi sector imaging gamma. Different geological data can be selected according to customer requirements to provide reliable data support for geological guidance control and block development. Zetianshenghai near bit geological guidance tool has played an important role in the development of coalbed methane in Shanxi Province, especially in the development of thin reservoir, the advantage of measuring points close to bit ensures high penetration rate and enhanced oil recovery; Effectively shorten the drilling time of the target layer and save the cost for the construction party.
5. High power underground turbine generator
With the continuous improvement of drilling quality requirements in the process of drilling operation, it is required to enrich geological data as much as possible. The traditional battery power supply mode will restrict the hooking and application of high-performance LWD (logging while drilling). The commonly used downhole turbine generator is often designed in complete sets with the mud pulser. The main purpose is to supply power to MWD (measure while drilling) measuring equipment and ensure that the mud pulser can produce sufficient energy pulse waveform. When such a generator is used to connect LWD tools, it will often encounter insufficient output power, which will affect the normal use of tools. In the use of high-power underground turbine generator, we will encounter various tests, such as high speed, high voltage ripple, unstable power supply output at low speed, abnormal electronic modules, easy eccentric wear of generator rotor and stator, and easy failure of rubber materials in high sulfur formation in Sichuan. The company’s subsidiary zetianshenghai underground high-power turbine generator has been recognized by the market and provides generator assembly and high-performance rectifier and voltage stabilizing module for relevant units such as PetroChina, Sinopec and CNOOC. The products include 100W, 150W, 200W, 300W and 500W series, which can not only meet the power supply of multiple LWD tools, but also provide supporting facilities for rotary steering drilling tools. The underground high-power turbine generator has the strength to replace similar imported generators and has been delivered to users.
6. Rotary guide tool accessories.
Rotary steering tool, which integrates various technical advantages of MWD, is an advanced drilling tool and has obvious advantages in automatic drilling operation. Due to the great technical difficulty, the main products and technologies are concentrated in the hands of several major foreign oil service companies. After several years of development and application, CNOOC and PetroChina have also achieved certain success. The rotary steering tool has advanced technology, complex design and good drilling effect. At the same time, it is accompanied by a pain point: the cost of accessories is high, the price of imported accessories is expensive and the supply cycle is long. In the process of developing independent rotation oriented tools, Zetian Shenghai, a subsidiary of the company, has made a technological breakthrough in the research and development of rotation oriented core accessories, which can customize a variety of core accessories, and the performance can meet the standards of imported similar products. It provides customized accessories for the rotary guide tools independently developed by CNOOC, PetroChina and other units, which has been recognized by users. 3.
