| Abstract: | Well TH302, the first 3D highly - deviated well inBendong oilfield, has a completed depth of 3854. Om, bottom hole horizontal displacement of 1585. 6m and maximum hole deviation angle of 87. 82?. Large deviation angle and varying azimuth pose strict requirements to trajectory control and downhole security. The well was successfully completed through strict technical measures such as trajectory control, friction and torque and borehole cleaning. |
