姬塬油田罗1长8油藏合理注水方式研究

摘要

It is the key that choose the reasonable water flooding mode for achieving the goal of controling water cut and keeping the stable oil production in water flooding reservoir.This areticle shows the reasonable water flooding mode of low permeability sandstone reservoir which will improve waterflood efficiency,supply reservoir pressure,slow decline of oil and develop the oilfield effectively,by taking measures such as reservoir engineering,numerical reservoir simulation and dynamic analysis,researching on water injection timing,water flooding mode,water injection intensity,separated-zone water flooding and so on in Luo 1 area which is a low permeability sandstone reservoir.%对于注水开发油藏,选择合理的注水方式进行开采,实现油田的稳油控水是关键。运用油藏工程、数值模拟结果结合生产动态,通过对低渗透油田罗1区块注水时机、注水方式、注水强度及水井分注等方面的研究,总结出适合该类油藏的注水方式,有效提高水驱效率、补充地层能量、减缓递减,实现油田高效开发。
