METHOD FOR STEAM THERMAL IMPACT ON HIGH VISCOUS OIL DEPOSIT

摘要

1. The method of heat and steam exposure to a reservoir of high-viscosity oil, including drilling rows of injection and producing horizontal wells, injecting steam through injection wells and selecting oil from production wells, characterized in that the horizontal wells are drilled to a length that is a multiple of the lateral distance between the wells , while the injection wells are divided into sections isolated from each other, and the steam is pumped into the sections separately with the possibility of controlling its flow rate, and between the injection pumps The oil and production wells in the area of each section monitor the dynamics of the front of oil displacement by steam and, depending on the magnitude and nature of the deviation in the dynamics of front movement in the area of different sections of the injection well, change the steam flow rate in the sections, maintaining uniform front movement along the entire wells. 2. The method according to claim 1, characterized in that the ratio of the length of horizontal wells to the distance between the wells is at least 3.
