Abstract

Abstract

The Well Shunbei 56X is a key pre-exploration well in the Shunbei V belt area. This well is completed in total depth of 9300m and vertical depth of 8087.94m. The static temperature at the bottom of the well is up to 178℃. Because there is fault zone in the reservoir stratum with complex geological condition such as broken strata， ultra-high depth and high temperature， challenges exists when drilled such as high friction and torque， difficult trajectory control， high failure rate of MWD， high bottom temperature， high rate of instrument broken and so on. In view of such technical problems， directional drilling technology system in ultra-deep well is built through optimizing the borehole trajectory， high temperature measuring instrument while drilling， drilling craft process， directional bit， fast control of tool face， drilling with the guidance of seismic data， and safety evaluation of ultimate extension capacity. The Well Shunbei 56X is the first horizontal well with the total depth exceeding 9000m in onshore Asia. The technology applied in Shunbei 56X well can provide technical support for exploration and development in Shunbei Oil & Gas Field.
