Integration of directional drilling, logging and rotary steering in Fuling Shale Gas Field

Abstract:

In order to improve ROP and efficiency in drilling in the Fuling Phase II complex structure, the rotary steering tool was introduced and the integrated operation mode of directional drilling, logging and rotary steering was applied. The integrated technology of directional drilling, logging and rotary steering was developed by selecting the rotary steering tool, matching formation characteristics with drilling bits, optimizing the trajectory control method, improving the existing information platform and rotary steering software. Field test in 8 wells in Fuling Shale Gas Field demonstrated that the reservoir intersection rate was obviously increased, the trajectory control was smooth, and ROP was obviously increased, which achieved the goal of “crossdisciplinary combination, innovation and development”, and has strong popularization and applicability.
