Abstract
Изобретение относитс к геофизике. Целью изобретени вл етс повышение эффективности способа изучени геодинамических процессов в земной коре. Цель достигаетс за счет того, что измерение электротеллурического пол дл изучени геодинамических процессов в земной коре провод т при заглублении электродов, осуществленном путем бурени в горной породе скважины, простирающейс ниже уровн верхней границы водонесущего сло , погружени одного электрода на дно скважины и засыпки ее до уровн водонесущего сло , где располагаетс второй электрод.This invention relates to geophysics. The aim of the invention is to increase the efficiency of the method for studying geodynamic processes in the earth's crust. The goal is achieved by measuring the electrotelluric field to study geodynamic processes in the earth's crust when the electrodes are buried, drilled in the rock of a well extending below the upper limit of the water-bearing layer, submerging one electrode to the bottom of the well and filling it to water bearing layer where the second electrode is located.
Description
изобретение относитс к геофизике и может быть использовано дл из- изучени геодинамических процессов земной коре.The invention relates to geophysics and can be used to study the geodynamic processes of the earth's crust.
Целью изобретени вл етс повышение эффективности.The aim of the invention is to increase efficiency.
Сущность предлагаемого способа заключаетс в следующем.The essence of the proposed method is as follows.
Диффузи поровой жидкости сопровождаетс по влением электрокинетического тока, который приводит к возникновению потенциального электрического пол , Дис})фузи поровой жидкости может быть следствием изменений объемной деформации земной коры, сопровождающей геодиначические процессы . Это происходит из-за изменени пористости горных пород и, какDiffusion of the pore fluid is accompanied by the appearance of an electrokinetic current, which leads to the appearance of a potential electric field, Diss). The fusion fluid of the pore fluid may be a consequence of changes in the volumetric deformation of the earth's crust accompanying the geodinatic processes. This is due to changes in rock porosity and, as
следствие, возникновени избыточного давлени поровой жидкости. Ненулевое поле будет только в случае, если измерительные электроды или один из них расположить ниже уровн грунтовых вод.the result is an overpressure of the pore fluid. A non-zero field will be only if the measuring electrodes, or one of them, is located below the groundwater level.
Способ изучени геодинамических процессов в земной коре реализуют следующим образом.The method of studying geodynamic processes in the earth's crust is implemented as follows.
В горной породе бур т скважину, простирающуюс ниже уровн верхней границы водонесзпцего сло . На дно скважины погружают один электрод и засыпают ее до уровн водонесущего сло , где располагают второй электРОД .In the rock, a well is drilled, extending below the level of the upper boundary of the water-non-flowing layer. At the bottom of the well, one electrode is immersed and it is poured to the level of the water-bearing layer where the second electrode is located.

Дл обнаружени кратковременных (минуты-часы-сутки) изменений напр женно-деформированного состо ни земной коры указанным способом целе- сообразно устанавливать электроды на рассто нии R 1 - Юм.; т.е. скважину бур т на глубину пор дка 1 - 10 м. Такие размеры выбраны из следующих соображений. С одной сто- роны, желательно сделать R как можно меньше, так как величина помехи пропорциональна R. При R 10 помехи практически отсутствуют. С другой стороны, врем существовани всплес- ка пол определ етс R и коэЗДициен- том диффузии жидкости. При очень малых R можно не заметить эффекта.Дл реальных значений коэфс ициента диффузии целесообразно брать R 5; i м, в In order to detect short-term (minute-hour-day) changes in the stress-deformed state of the earth's crust in this way, it is advisable to set the electrodes at a distance R 1 - Hom; those. the well is drilled to a depth of the order of 1 to 10 m. Such dimensions are chosen from the following considerations. On the one hand, it is desirable to make R as small as possible, since the magnitude of the interference is proportional to R. With R 10, there is practically no interference. On the other hand, the lifetime of the burst field is determined by R and the diffusion coefficient of the fluid. For very small R, one can overlook the effect. For real values of the diffusion coefficient, it is advisable to take R 5; i m in
этом случае можно зафиксировать эффект с 61 5 1 мин.In this case, you can fix the effect with 61 5 1 min.
