Abstract

Способ обеспечения программы нагнетания в скважину, в котором исследование приемистости скважины осуществляют на оценочной скважине. Выбирают оценочную скважину, располагают скважинные датчики в скважине для измерения давления и температуры, воду нагнетают в скважину за последовательность испытаний путём скачкообразного изменения расхода нагнетаемой воды или циклов нагнетания, моделируют данные для определения характеристики температурного напряжения скважины, и посредством моделирования резервуара определяют оптимальные параметры нагнетания для обеспечения максимальной добычи посредством программы нагнетания в скважину. Это устраняет необходимость осуществления нескольких измерений характеристик температурного напряжения на керновых образцах.A method for providing a well injection program, in which a well injectivity study is performed on an appraisal well. An appraisal well is selected, downhole sensors are placed in the well to measure pressure and temperature, water is injected into the well in a sequence of tests by an abrupt change in the flow rate of injected water or injection cycles, data is simulated to determine the characteristic of the temperature stress of the well, and by modeling the reservoir, the optimal injection parameters are determined for ensuring maximum production through the well injection program. This eliminates the need to perform multiple measurements of thermal stress characteristics on core samples.
