    Abstract:

    In the drilling of kilometer level wire line coring horizontal holes, the research and demonstration of directional deviation correction and logging technology for horizontal holes are carried out. The technology of full hole wire line coring deviation correction for deep horizontal directional drilling was innovated and formed, and the precise control of the drilling track was realized. Using hydraulic transmission of geophysical testing equipment and drilling television equipment inside the drill pipe has effectively solved the three major problems of difficulty in delivering, testing, and proposing ultra-long horizontal boreholes, forming a comprehensive logging technology system for small caliber and ultra-long horizontal boreholes. The drilling task of 925m deep horizontal directional drilling hole was successfully completed, accurately entering the geological target area and realizing the exploration purpose.
