萨北东部过渡带一条带葡I组聚驱于2002年12月投入开发,由于受窄小条带发育的油层条件及过渡带原油物性等因素的限制,在250m井距五点法面积井网条件下,聚驱注入状况差,油井见效比例低。为了改善东部过渡带聚驱开发效果,2008年通过利用水驱井网缩小井距进行注采系统调整,再进行聚驱开采的方法,为整个过渡带今后的长远开发效果提供一定的指导意义。
In the transitional belt in the northern part of Northern Saab, a group I polyaduncture with Portuguese I was put into development in December 2002. Due to the constraints of reservoir conditions and the physical properties of the transition zone crude oil in the narrow belt, Under conditions, poly-flooding poor injection conditions, the proportion of wells effective low. In order to improve the development effect of poly-flooding in the transitional zone of the eastern part of China, in 2008, by adjusting the injection-production system by reducing the well spacing with the water-driven well pattern and then carrying out the poly-flooding method, it is of guiding significance for the long-term development effect of the whole transition zone in the future.
