低渗透油田高含水开发期剩余油分布类型及挖潜技术

Residual oil distribution and digging technology in the low permeability reservoirs during the high water develop period

通过对高含水区块开展油藏精细描述,对高含水开发区块的剩余油进行了定性、定量研究,有效评价剩余油分布方向。提出的挖潜方法有效提高了区块采油速度和水驱动用储量。

By analyzing the fine oil reservoir in the high water block,we study the type of the residual oil both qualitatively and quantitatively for effective evaluation of the distribution and direction of the residual oil.The corresponding digging methods are proposed,which improves the production of oil and efficiently use the water reserves for driving.
