1.6 Technical services for drilling horizontal wells and large-slope directional wells with windows on small wellbores.

Using special drilling tools and supporting window opening and inclined tools, casing windows can be opened at any position above 10 meters of the old well target layer, and enter the oil layer with a slope of 3-7.6 °/m (228.6 °/30m) and a displacement of about 20 meters. The horizontal section trajectory adjustment capacity can reach 0.5-1.5 °/m, and the vertical depth of the 10m foot can be adjusted more than 1.0m, efficiently ensuring the drilling rate of the oil layer and the realization of geological adjustment goals.

2.1. Radius of curvature: It can be controlled within 30 meters, with a minimum of 7.6m;

2.2. Distance before the target: 10-30m

2.3 Horizontal length: Maximum 400m

2.4 Logging and measuring tools: gyro, azimuth, MWD wired drilling well logging

2.5 Complete method: open hole, screen tube or casing, can fix the well
