Abstract

Изобретение относится к нефтяной промышленности, в частности к гидродинамическим методам исследования скважины и может быть использовано в определении параметров пласта-коллектора. Сущность изобретения состоит в способе определения гидропроводности нефтяного пласта-коллектора. Способ включает остановку скважины при нижнем положении плунжера станка-качалки. Отслеживают скорость восстановления забойного давления через равные интервалы времени при неустановившемся режиме фильтрации после остановки скважины. Строят кривую восстановления забойного давления в полулогарифмических координатах и описывают всю КВД следующей формулой:где P(t) и P, - соответственно, текущее значение забойного давления и его значение в момент остановки скважины; P- давление в контуре пласта; m, n + 1 - постоянные коэффициенты, определяемые по экспериментальным данным. Сравнение расчетного значенияс фактическим значением гидропроводности пласта, определяемые по керну, показывает, что предложенный способ позволяет с погрешностью не более 4,0% определить ГП пласта.The invention relates to the oil industry, in particular to the hydrodynamic methods of research wells and can be used in determining the parameters of the reservoir. The essence of the invention consists in the method of determining the hydroconductivity of an oil reservoir. The method includes stopping the well at the lower position of the plunger of the pumping unit. Track the recovery rate of bottomhole pressure at equal intervals of time with unsteady filtering mode after a well has stopped. Build a bottomhole pressure recovery curve in semi-logarithmic coordinates and describe the entire ARC by the following formula: where P (t) and P, are, respectively, the current value of the bottomhole pressure and its value at the moment of well shutdown; P - pressure in the reservoir circuit; m, n + 1 are constant coefficients determined from experimental data. Comparison of the calculated value with the actual value of the hydraulic conductivity of the reservoir, determined by core, shows that the proposed method makes it possible to determine the reservoir HP with an error of no more than 4.0%.
