Abstract

Раскрываются способы и устройства для определения смыкания подземной трещины. Способы могут предусматривать подачу электрического тока на обсадную трубу скважины, проходящую от поверхности земли в подземную толщу горных пород, которая имеет трещины, по меньшей мере, частично заполненные электропроводящим проппантом, и измерение первого отклика электрического поля на поверхности или в стволе соседней скважины в течение первого временного интервала для получения первого измерения поля. Эти способы могут также предусматривать измерения второго отклика электрического поля на поверхности или в стволе соседней скважины в течение второго временного интервала с целью получения второго измерения поля и определение увеличения давления смыкания на электропроводящем проппанте по разности между первым и вторым измерениями поля.Disclosed methods and devices for determining the closure of underground cracks. The methods may provide for the supply of electric current to the well casing extending from the surface of the earth into the subterranean formation, which has cracks at least partially filled with electrically conductive proppant, and measuring the first response of the electric field on the surface or in the wellbore of the neighboring well time interval for the first measurement of the field. These methods may also include measuring the second response of the electric field on the surface or in the wellbore of a neighboring well during the second time interval in order to obtain a second field measurement and determine the increase in clamping pressure on the electrically conductive proppant from the difference between the first and second field measurements.
