CNPC Well Logging North China Branch successfully completed the first operation of the controllable shock wave major scientific research project test in the Sulige area of ??Sichuan Petroleum Drilling. The success rate of the instrument going down to the well was 100%, the data quality rate was 100%, and the monitoring data records were normal, achieving the expected goals.
It is reported that this project is a major scientific research project of the group company jointly implemented by CNPC Well Logging and Sichuan Petroleum Drilling. This technology uses cables to transport impact tools down the well to establish a transformation foundation for subsequent perforation and fracturing.
This test is the first time that this technology has been applied to the Sulige gas field area, and its purpose is to collect relevant data on deep coal-rock gas development. During this construction, the operation team arrived at the construction site in advance to make production preparations and ensure the implementation of various safety and environmental protection responsibilities. A total of 68 high-energy ion impact ignitions and 2 long-range dipole acoustic logging were carried out, and relevant data were successfully monitored and recorded.
The smooth construction of this well further demonstrates the technical capabilities of CNPC Well Logging in the field of perforation technology. In the next step, the well will carry out 40-arm wellbore, sector cement bonding, electromagnetic flaw detection logging and negative pressure perforation operations, laying a solid foundation for the innovation of reservoir transformation and trial repair mode in the region.
