Способ стабилизации направления ствола скважины, включающий спуск в скважину колонкового набора, состоящего из коронки, колонковой трубы и переходника, бурения с отбором керна, извлечением его на поверхность в колонковом наборе, визуальное определение места контакта колонковой трубы со стенкой скважины в процессе бурения и корректировку параметров колонкового набора, отличающийся тем, что после визуального определения места контакта колонковой трубы со стенкой скважины рассчитывают точку прогиба колонковой трубы в месте контакта со стенкой ствола скважины по формуле
Figure 00000001

а корректировку параметров колонкового набора осуществляют деформацией изгиба колонковой трубы в точке ее прогиба в месте контакта со стенкой скважины в противоположную сторону от места контакта на величину
Figure 00000002

где Lб.в. - длина полуволны изгиба бурильных труб над колонковым набором, м;
fб.в. - полуразность диаметров бурильных труб и скважины, м,
fп - полуразность диаметров скважин и переходника колонкового набора, м;
E•Iк.н., E•Iб.в. - соответственно жесткость поперечного сечения колонкового набора и бурильных труб, даН•м2
Lк.н.- длина колонкового набора, м.
A method of stabilizing the direction of the wellbore, including the descent into the well of a core set consisting of a core, core pipe and adapter, drilling with coring, extracting it to the surface in the core set, visual determination of the contact between the core pipe and the wall of the well during drilling and adjusting the parameters core set, characterized in that after visual determination of the contact point of the core pipe with the well wall, the deflection point of the core pipe at the point of contact with wellbore wall according to the formula
Figure 00000001

and the correction of the parameters of the core set is carried out by bending the core pipe at the point of its deflection at the point of contact with the wall of the well in the opposite direction from the point of contact by
Figure 00000002

where L b.v. - the half-wave length of the bend of the drill pipe over the core set, m;
f b.v. - half the diameters of the drill pipe and borehole, m,
f p - the half-difference of the diameters of the wells and the adapter core set, m;
E • I Ph.D. , E • I b.v. - respectively, the rigidity of the cross section of the core set and drill pipe, daN • m 2
L Ph.D. - the length of the column set, m
