Development and Application of Magnetic Guidance Measurement System for Dual-horizontal Well with Small Well Spacing in Medium-to-low Maturity Shale Oil
In the context of the continuous growth of global energy demand and the transformation of the oil industry to unconventional oil and gas resources,China's rich shale oil resources,especially the development of medium and low maturity shale oil,have attracted much attention.Focusing on the challenge of accurate drilling trajectory measurement in the development of medium-low maturity shale oil,the MixMeasure magnetic guidance measurement system was innovatively developed in this paper.By positioning and guiding the forward drilling through the magnetic signal emitted from the magnetic source,the system can automatically optimize the filter frequency band range and effectively eliminate the noise interference in complex environment,and integrate high-precision distance and angle calculation models to achieve a high-precision measurement of 0.2 meters in distance and 1.7 degrees in angle.This technological breakthrough solves the stable measurement problem in the drilling process of small well spacing in complex environments and meets the drilling guidance demand of dual horizontal wells with a well spacing of less than 10 meters.The application of the MixMeasure magnetic guidance measurement system provides reliable data support for shale oil drilling,improves the safety and efficiency of drilling,not only promotes the development of medium-low maturity shale oil,but also provides important technical support for the sustainable development of oil and gas exploration and development.
