The Iterative Upgrade of CPC Logging Crawler Perforation Technology

The Iterative Upgrade of CPC Logging Crawler Perforation Technology

On May 8, the reptile perforation technology independently developed by CNPC logging was upgraded and upgraded. Previously, CNPC logging applied the crawler perforation technology to successfully complete the first section of three Wells in Changning H30 platform, realizing the maximum crawling distance of 3080 meters, the maximum well slope Angle of 104.04 degrees, and the maximum crawling speed of 450 meters / hour. The upgraded technology has more stability, faster crawling speed, and more reliable transmission and communication.

CPC logging adhere to the market demand orientation, crawling perforation key theory difficulties, complete large load traction speed and push on pressure matching control research, innovation put forward "double core cable asynchronous communication and shunt control method," finally to "dual core coaxial cable + all-wheel drive dynamic flexible roller string + fine construction control process" as the core of crawling delivery perforation technology, overcome the long horizontal section of large load crawling difficult, large slope section safety braking, perforation impact buffer engineering problems, such as effective promotion crawling transmission perforation capacity.

In the field construction, the company adopted the self-developed TRAC4900 crawler, and strictly in accordance with the "one well one policy" customized the long horizontal well, the success rate of the crawler reached 100%, so that the first show of the perforation technology achieved bright results.
