Способ контроля, процесса бурения наклонно-горизонтальных скважин, включающий бурение ствола скважины компоновкой бурильной колонны, состоящей из долота, забойного двигателя, телеметрической системы; бурильных труб, и определение осевой нагрузки на долото, отличающийся тем, что измеряют число оборотов долота при помощи датчика, установленного в автономном скважинном приборе, расположенном в переводнике между долотом и валом забойного двигателя, с передачей информации от датчика по беспроводному каналу, например, ультразвуковому каналу или любому другому, в скважинный прибор телеметрической системы, установленной над забойным двигателем, и далее по кабелю (или другим способом) на поверхность, а величину осевой нагрузки определяют по формуле:
Figure 00000001

где nx - частота вращения долота при холостом режиме (паспортная характеристика вала забойного двигателя);
n - частота вращения долота (вала забойного двигателя), замеренная датчиком;
k - коэффициент пропорциональности, определяемый опытным путем при стендовых испытаниях забойных двигателей.A control method for a directional horizontal well drilling process, comprising: drilling a wellbore with a drill string assembly consisting of a bit, a downhole motor, a telemetry system; drill pipes, and determining the axial load on the bit, characterized in that they measure the number of revolutions of the bit using a sensor installed in an autonomous downhole tool located in the sub between the bit and the shaft of the downhole motor, transmitting information from the sensor via a wireless channel, for example, ultrasonic channel or any other, into the downhole tool of the telemetry system installed above the downhole motor, and then through the cable (or in another way) to the surface, and the magnitude of the axial load is determined by the formula:
Figure 00000001

where n x is the rotational speed of the bit when idle (passport characteristic of the shaft of the downhole motor);
n is the rotational speed of the bit (shaft of the downhole motor), measured by the sensor;
k is the coefficient of proportionality determined empirically during bench tests of downhole motors.
