Essay

The thesis deals with the improvement of technology and bottom-hole assembly designs for drilling directional and horizontal boreholes with large inclination angles in unstable rocks of oil and gas fields of the Dnipro-Donetsk depression and Black Sea offshore zone. As a result of analytical, experimental and industrial researches the critical angle values in terms of directional wellbore walls stability loss in the process of drilling in unstable rocks were determined and, under the same conditions, the deviation intensity limit value scope in those rocks was measured. The analytical dependence of bit thrust load transmission on the value of inclination angle and well deviation intensity was detected.
