On February 21, it was learned from China Cssc Holdings Limited(600150) 722 institute that haikuo company, the holding company of the Institute, successfully won the bid for the cooperative development project of horizontal well transportation system of CNPC logging company, marking that haikuo company entered the scientific and technological innovation ecosystem of CNPC logging and made an important breakthrough in the field of key intelligent equipment for shale oil and gas.
It is reported that the intelligent horizontal well transportation technology equipment is a high-end equipment urgently needed for shale oil and gas development, with large application demand, but the technology in the industry has been monopolized by foreign companies for a long time. Foreign companies only provide services in China, do not directly sell products, and the service price is high.
In order to fill the gap in the field and meet the market demand, haikuo company established a special research project team, which lasted more than 4 years and independently developed hktrac type haikuo underground crawler. The key technical indicators of this type of crawler have reached the advanced level of foreign high-end equipment, and are more suitable for the Chinese market. At present, it has been gradually applied to many large oil fields in China.
In petroleum logging exploration, crawler is an important transportation tool for downhole equipment in cased horizontal wells and highly deviated wells. This type of crawler adopts the design of full hydraulic sealing structure, which can work normally at the depth of 6000 meters underground, with the maximum applicable ambient working temperature of 175, breaking the global record of high temperature resistance of similar equipment. When working at the depth of 6000 meters, it can crawl at the maximum speed of 1000 meters / hour and the maximum distance of 3000 meters.
“This type of crawler can operate multiple wells continuously and greatly reduce the maintenance cost. When the downhole equipment cannot be continuously lowered to the target well section by gravity, the crawler can use its own power equipment to transport the equipment to the target well section.” According to the relevant person in charge of haikuo company, compared with the conventional drill pipe transportation and coiled tubing transportation, the crawler does not need the derrick and is not affected by the well depth, which can effectively save the construction time, reduce the labor intensity and reduce the construction risk.
