FIELD: oil-and-gas industry. ^ SUBSTANCE: invention related to oil industry, particularly to oil reservoir filtration characteristics determination methods. The method of oil reservoir drainage volume filtration characteristics determining according to the well operation data includes determination of disturbance signal velocity in a drained reservoir space, between interacting injection and operation wells, by response signal delay time and distance between wells. For disturbance signal velocity estimation use as the response signal a production well dynamic level respond on disturbance, generated by working agent injection into injection well volume change. At that preliminary define disturbance signal velocity between wells, which has lab data on core filtration characteristics quantitative assessment. Draw curve dependances between disturbance signal velocity quantitative data and filtration characteristics values. According curves define filtration characteristics in the drained reservoir hole clearance for the rest interacting well pairs, with the disturbance signal velocity defined, but not characterised with the core material. ^ EFFECT: filtration characteristics assessment reliability and accuracy increase because of number of definition increase. ^ 4 dwg |
