摘　　要：在构造特征研究、精细地层对比、沉积相研究的基础上,利用油藏数值模拟软件建立了姬嫄油田罗1开发试验井区长8油藏数值模型.通过对区块地质储量、产液、含水率及单井生产历史的拟合,从井网系统、开发方式、注水时机以及压力系统4个方面,优选出了油田开发方案:井网形式采用菱形反九点井网,井距为485 m、排距为140 m,井网密度为14.73口/km2;开发方式为注水开发;开发时机为注水至p/pi=105%;采油井井底流压为7.0 MPa.On the basis of the research of structural characteristics,fine stratigraphic correlation and sedimentary facies,the numerical models of the Chang-8 reservoir in Luo-1 test area of Jiyuan Oilfield are established using reservoir numerical simulation software. By the history fitting of the geological reserves,liquid production,water content and single-well production,the optimal development plan of the studied area is selected from four aspects of well pattern,development approach,water injection timing and pressure system: well pattern is diamond-shaped inverted nine spot well pattern,well spacing is 485 m,row spacing is 140 m,the well spacing density is 14. 73 / km2; advanced water injection development is used,and water injection reaches to p/p i = 105%; bottomwell flowing pressure is 7. 0 MPa.
