Abstract
1. Способ контроля искривления ствола скважины, заключающийся в измерении величины прогиба бурильной или насосно-компрессорной трубы скважины с помощью скважинного прибора, спускаемого вертикально в трубу скважины, отличающийся тем, что в качестве скважинного прибора применяют обратимый акустический преобразователь с равномерной характеристикой направленности, работающий в режиме последовательности зондирующих импульсов, при этом, о величине прогиба ствола скважины судят по уширению отраженных от стенок зондирующих импульсов.2. Способ по п.1, отличающийся тем, что в качестве зондирующих акустических импульсов используют последовательность радиоимпульсов прямоугольной или колоколообразной формы.3. Способ по п.2, отличающийся тем, что в качестве зондирующих акустических радиоимпульсов используют радиоимпульсы с частотой заполнения равной 10.4. Способ по п.2, отличающийся тем, что в качестве зондирующих акустических радиоимпульсов используют последовательность радиоимпульсов, следующих со скважностью равной 10.5. Способ по п.1, отличающийся тем, что в качестве зондирующих акустических импульсов используют радиоимпульсы длительностью 10с.1. A method of controlling the curvature of a borehole, which consists in measuring the deflection of a drill or tubing using a borehole tool that is lowered vertically into the borehole, characterized in that a reversible acoustic transducer with uniform directivity is used as the borehole device, working in in the sequence of probing pulses, while the magnitude of the deflection of the wellbore is judged by the broadening of the probe pulses reflected from the walls. 2. The method according to claim 1, characterized in that a sequence of radio pulses of a rectangular or bell-shaped shape is used as sounding acoustic pulses. The method according to claim 2, characterized in that as sounding acoustic radio pulses using radio pulses with a filling frequency equal to 10.4. The method according to claim 2, characterized in that the sequence of radio pulses following with a duty cycle of 10.5 is used as sounding acoustic radio pulses. The method according to claim 1, characterized in that as sounding acoustic pulses using radio pulses of a duration of 10 s.
