After receiving the construction task, North China Measurement and Control responded quickly and quickly established a cooperative research team with Party A. After research and decision, the new technology "Jingwei Gangyi" tractor independently developed by Jingwei Company was innovatively used in coalbed methane horizontal wells, and RBT was carried out for logging construction. The technicians arrived at the site as soon as possible to understand the information of the construction wells, and formulated detailed technical guarantee measures for the key links and technical difficulties in the construction. At the same time, equipment commissioning and full-process construction simulation were carried out in advance, and the risks and hidden dangers that may arise in the construction were analyzed, and corresponding preventive measures were formulated. During the construction, the logging construction team strictly implemented the logging construction plan and operating procedures, and the personnel in various positions coordinated closely to complete the construction tasks safely and efficiently. The one-time success rate and excellent product rate of logging were both 100%.
In addition, the cooperative research team established a real-time monitoring and remote control technology platform equipped with intelligent technology achievements, which effectively avoided the drawbacks of traditional logging construction. The "segmented and divided speed" logging process was adopted to increase the time efficiency of single well operations by more than 35%. Innovative cementing quality logging mode, adopting 360-degree full-well circumference cementing quality evaluation data accurate collection, realizing the upgrade of cementing quality evaluation from "fuzzy scanning" to "precise diagnosis", greatly improving the quality of fine evaluation, and providing efficient and reliable technical support for deep coalbed methane exploration and development.
