Southwest Survey and Control Lantern Body Electrical Imaging Liangjian Yuanba

Sinopec News Network reported recently, with the last trip of the electrical imaging instrument safely out of the wellhead, the quartet integrated and special logging task of Yuanfei 203H well constructed by Petrochemical Jingwei Southwest Measurement and Control Company was successfully completed
.
This marks the first appearance of the lantern-type electrical imaging instrument independently developed by the company and successfully gnawed down the "hard bone" of Yuanfei 203H Well!

"Our lantern-type electrical imaging is really easy to use.
It can be used for both up and down measurements, and it solves the problem of instrument jamming and jamming
.
" The old employees with many years of electrical imaging logging construction experience are full of praise

The lantern-type electrical imaging instrument has the advantages of ultra-high temperature and high pressure indicators (200°C, 172MPa), and realizes the logging function of drilling tool transportation, reducing the probability of blocking the electrical imaging plate from falling into the well
.
In this construction, the instrument showed significant advantages such as high temperature and pressure resistance, stable and reliable work, high-quality imaging data, and high logging efficiency

Well Yuanfei 203H has a depth of 6494m, bottom hole temperature of 148℃ and pressure of 137MPa.
It is a typical ultra-deep, high-temperature and high-pressure well in the Yuanba block.
It is currently drilled into the limestone formation of Feixianguan Formation, with complex geological conditions and strata.
Contains hydrogen sulfide
.
Conventional logging tools cannot withstand such an extreme downhole environment for a long time, and the limestone formation has complex anisotropy, and it is easy to encounter blockage during the start and run of the tool.

If a worker wants to do his job well, he must first sharpen his tools
.
In the face of challenges, Petrochemical Jingwei Southwest Measurement & Control Co.

The successful completion of this logging construction not only demonstrates the hard power of Southwest Measurement & Control Company's "excellent technical level and first-class management and construction", but also demonstrates the spirit of Southwest Measurement & Control people's "concentration, overcoming difficulties, and the courage to innovate".
God
.
In particular, the successful field application of the lantern-type electrical imaging instrument has further enhanced the technical reserve capacity of Southwest Observation and Control Company.
