Because it is necessary to increase the area of lacustrine and increase the production capacity of oil wells, horizontal wells, horizontal branch wells, and large wells are widely promoted in oil fields. If only the cable measurement technique is used in the drilling process, the deviation of the drill bit from the design drilling trajectory can easily occur, resulting in accidents such as the drilling of the partial target and the failure of the drilling process to reach the geological target layer, and the coring error caused by the depth error during drilling.

Drill-through measurement is a comprehensive technical system for cable measurement, logging, and drilling. It can accurately and in real time provide site engineering technicians with physical parameters of rock and geology that meets the formation, which helps the staff to monitor the formation and understand the formation. The situation.
