Abstract

Latterly, oil and gas pipelines are laid not on the bottom of the reservoir, but in wells under the reservoir, for which the inclined and horizontal drilling is carried out. At the same time, failures occur in the design of the drillstring bottom. The theory of horizontal drilling has not been developed yet. The solution is given to the problem of internal forces determining in a drillstring for inclined and horizontal drilling and their change as a result of interaction with the ground.
