下二门油田中层系剩余油分布及注采井网综合调整研究

Middle layer residual oil distribution and injection production well pattern aggregate adjustment of Xiaermen oilfield

针对下二门油田中层系处于特高含水开发后期存在的诸多问题,如:平面、层间矛盾突出、动用程度差异大、剩余油分布零散复杂、井网密度大、综合含水高等,在剩余油分布研究后开展井网适应性研究、井网调整潜力研究、井网调整技术经济界限研究,依此制定了注采井网综合调整对策,进行了井网综合调整部署。

Xiaermen oilfield middle layer is in the laterhigh watery development period with many problem existed,such as the plane, interlayer contradictory prominent, theproducing degree difference is big, residual oil distributionscattered complex, well pattern density is big, comprehensive water content is higher. Therefore we carried out research on well pattern adaptability, the pattern modificationpotential, the pattern modification technology economicalboundary after remaining oil distribution research and formulated the well pattern overall adjustment countermeasure,and carried on the well pattern overall adjustment deployment.
