On October 22, the Changqing Division of CNPC Logging Co.
, Ltd.
successfully completed the cementing quality logging task of horizontal wells with a depth of 3,375 meters, a large slope section from 60 degrees to the bottom of the well and a length of 270 meters in only 9 hours in Changqing Sulige Gas Field, which was nearly 25 hours
less than the traditional process.
All the data obtained are qualified and valid, indicating that the research and application of hard cable logging technology in China has made breakthroughs
.
The hard cable logging process is suitable for the measurement
of horizontal wells or large slope horizontal wells with a depth of about 4000 meters and a horizontal section below 400 meters.
Its logging cable is made of high-strength hard steel wire as the outer armor, and in the absence of drilling tool transportation, it uses its own strong gravity to safely and quickly push the logging instrument to the target depth

.
As of October 24, Changqing Division has used the hard cable logging process to complete the cementing quality logging task of 55 wells with large slope and short horizontal wells, the average operation time is only 1/4 of the traditional process, and the qualification rate and excellent rate of logging data have reached 100%.
