Recently, the XN305 team of Petrochemical Jingwei Southwest Measurement and Control Company successfully completed 3 wells on the Weiye 34 platform, with a total of 48 stages of fracturing monitoring construction tasks
.
The micro-seismic fracturing monitor under this construction has been working stably for nearly 30 days in a high temperature environment of nearly 120℃, which provides important data support for the evaluation of fracturing effects, and also means that the company's micro-seismic fracturing detection technology is becoming more and more.
Microseismic fracturing monitoring technology is mainly used in shale gas hydraulic fracturing monitoring, which can effectively locate the fractures formed by downhole fracturing, and is of great significance for guiding fracturing operations and evaluating fracturing effects
.
In recent years, in order to meet the development needs of Weiyuan-Yongchuan deep-seated shale gas, Southwest Observation and Control Company has focused on creating cutting-edge technology, committed to the research and development of high-temperature microseismographs and microseismic monitoring and interpretation research.
Since its promotion and application in 2019, it has passed 2 years With many improvements and improvements, the application of microseismic fracturing monitoring has achieved the expected results, and significant results have been achieved in the construction of 8 wells
.
This construction task is the first time that Southwest Observation and Control Company has applied microseismic instruments to continuous construction operations in platform wells
.
In order to reduce the failure rate of continuous operation of the instrument in a high temperature environment, the company organized the backbone personnel of the instrument repair station and the technician innovation studio to solve the problems of the instrument power board overload and the poor insulation of the geophone connector in the early stage
It is reported that in the next step, the company will establish an electronic ledger for instrument operation, track the operation of each geophone for the entire life cycle, continuously improve the level of equipment management and operation, and strive to build the microseismic fracturing monitoring technology into a Southwest Measurement and Control Company.
Another bright business card provides strong support for the development of deep shale gas
