"The operation of ultra deep wells with a well depth of more than 7000 meters benefits from your continuous pipe butt welding technology." Mention the use of ct110 steel grade provided by Petrochina Company Limited(601857) Baoji Petroleum Steel Pipe Co., Ltd. (hereinafter referred to as Baoji steel pipe company) Ф fifty point eight × Fei Jiegao, deputy chief engineer of Changqing downhole technical operation company of Chuanqing drilling company, praised the 4.0mm long 9000 m butt welded continuous pipe for successfully completing the through flushing and perforation of well Jing 51-30h1, creating the deepest construction record of 6835 m Chinese continuous pipe horizontal well and equalling the construction record of 3500 m Chinese continuous pipe.
With the development of tight oil, tight gas, shale gas and other oil and gas resources, the number of deep wells and ultra deep wells in each oilfield is increasing, which puts forward higher requirements for the length of continuous pipe. However, restricted by factors such as transportation height and width limit, the length of single coiled continuous pipe is difficult to meet the requirements of well depth, especially Ф 50.8mm/ Ф It is difficult to meet the operation requirements of deep wells, ultra deep wells and ultra long horizontal wells.
In order to solve the problem of limited length of single coil of large-diameter continuous pipe, Baoji steel pipe company has determined the on-site butt welding scheme, carried out a series of butt welding continuous pipe process research, formed a set of mature on-site butt welding process guidance documents for large-diameter continuous pipe, and developed a set of service equipment suitable for large-diameter continuous pipe butt welding in oil field, The equipment operating procedures and operating parameters are determined.
"Do a good job in customer demand analysis, achieve a step and upgrade every year, and further meet the needs of customers." Shu Gaoxin, party secretary and executive director of Baoji steel pipe company, often emphasizes this.
In recent years, Baoji steel pipe company adheres to the development direction of service-oriented intelligent manufacturing and has independently developed 7100m ct130 steel grade Φ fifty point eight × 4.44-4.8mm variable wall thickness continuous pipe has carried out through washing and perforating operations in xhw5409 and xhw5406 wells in Fengcheng operation area of Xinjiang Oilfield, conquered the core technology of super continuous pipe manufacturing, independently developed the world's highest strength ct150 continuous pipe product, and developed flexible composite pipe products for oil field surface gathering and transmission around the serious corrosion of oil field metal pipes. Provide equipment and sharp tools for the development of unconventional oil and gas and "unconventional" oil and gas resources such as ultra deep wells and long horizontal wells in China.
At the same time, according to the special needs of customers for coiled tubing, it has organized the development and promotion of personalized products such as well completion string, cable threading coiled tubing and 2205 high alloy coiled tubing, formed businesses such as coiled tubing life cycle management, personalized product promotion, downhole operation and product extension services, and played the role of service driving product sales, It improves the value-added and efficiency creation ability of service business. Up to now, nearly 10000 tons of continuous pipe products have been provided to customers throughout the year, with a year-on-year increase of more than 20%.
Baoji steel pipe is located in Baoji high tech Zone, Shaanxi Province. It is one of the 156 key construction projects during the first five year plan period in China. It is also a large backbone professional welded pipe manufacturer producing large-diameter spiral submerged arc welded pipes in China.
