油藏井网综合调整技术在文51块中的应用

Application of Oil Reservoir Well-net General Adjusting in Wen 51-Block

针对濮城油田文 5 1块在注水开发中层间和平面矛盾突出 ,水驱动用程度低 ,油藏开发效果差的特点 ,通过对油藏精细描述 ,在弄清构造和剩余油分布的基础上 ,对开发井网进行综合调整 ,完善了注采井网 ,实现了多层砂岩特高含水期油藏开发对象的转移 ,提高了二、三类层水驱动用程度 ,降低了综合含水 ,年产油增加 ,开发效果得到了明显改善。

Contraposing the peculiarities of extrude inconsistency in interbedded and plane at adjection-water exploitation Wen51-Block in Pucheng oil field,and the lowness of water drive degrees,exploiture effect of oil is not good. The fine description for oil reservoir,make clear conformation and left oil distributing, againest general adjusting for well-net, perfected well-net,achieved many sandstone oil exploitation object displaced at containing more water time,and advanced water drive degrees in the second layer or the third one,reduced integrated water contains,the annual yield has increased,the exploitation impact has gained evidence improvement.This method have supervise for the same oil reserveoir well-netadjusting.
