Изобретение относитс к геофизическим исследовани м геологического разреза скважин, бур щихс на нефть и газ.The invention relates to geophysical surveys of a geological well section drilling for oil and gas.
Цель изобретени - упрощение вы- делени проницаемых интервалов в разрезе бур щейс скважины. The purpose of the invention is to simplify the allocation of permeable intervals in the section of a drilling well.
На фиг.1 показано устройство дл реализации способа} на фиг.2 - регистрируема диаграмма, соответстг вукща разрезу, показанному на фиг.1Figure 1 shows a device for implementing the method} in figure 2 - the recorded diagram, corresponding to the section shown in figure 1
Устройство состоит из корпуса 1, спускаемого на геофизическом кабеле, электродвигател 2, вращающего винт 3. Ток, потребл емый электродвигателем , регистрируетс обычным путем с помощью наземных блоков.The device consists of a housing 1, run down on a geophysical cable, an electric motor 2 rotating a screw 3. The current consumed by the electric motor is recorded in the usual way with the help of ground blocks.
Предлагаемый способ осуществл ют следующем образом.. The proposed method is carried out as follows.

Поскольку изменение плотности и в зкости промывочной жидкости против проницаемых объектов из-за оттока фильтрата в пласт зави- сит от свойств горной порорД) (чем больше проницаемость породы, тем больше фильтрата уйдет из раствора, а это ведет/ к увеличению концентрации в нем глинистых частиц), то при прохождении прибором интервалов с различной плотностью и в зкостью промывочной жидкости (Y i c Ofjbody and move the device along the wellbore. Since the change in the density and viscosity of the flushing fluid against permeable objects due to the outflow of filtrate into the formation depends on the properties of rock D) (the higher the permeability of the rock, the more the filtrate leaves the solution, and this leads to an increase in the concentration of clay particles ), then when the device passes intervals with different density and viscosity of the flushing fluid (Y ic Ofj

These current values are recorded by devices on the surface. By increasing the current, the permeability of the rocks composing the borehole is judged.
