摘要
通过对喇、萨、杏油田目前井网、层系和地质特征的分析,从理论上研究了油田采液指数、吸水指数的变化趋势和相对关系,确定了喇、萨、杏油田合理油水井数比的变化趋势,利用数值模拟手段和注采系统调整试验资料以及喇、萨、杏油田的开发特点,确定了注采系统调整的原则和界限。通过对喇、萨、杏油田现注采系统适应性的评价,提出了“八五”期间注采系统调整的部署意见和具体方案,并预测了调整效果和社会经济效益,对油田长远规划部署具有重要的意义。
<ABSTRACT>: Through the analysis of present well patterns, objective intervals and geological characteristics of Lamadian, Saertu & Xingshugang reser-voirs, changing trend analysis of the fluid productivity index & water injectivity index and their relative relations to the reservoir arc discussed theoretically, determining the changing trend of the ratio of oil and wa-ter wells.The principle and limits of the adjustment of injection-production systems are determined using numerical simulation, experimental data of adjusted injectio-nproduction systems and development characteristics of Lamadian, Saertu & Xingshugang reservoirs. By analyzing the adaptabi-lity of present injection-production systems of Lamadian, Saertu & Xings-hugang reservoirs, deployment & specific plans of injection-production system adjustment during the 'Eighth Five Year Plan' periodis put forward, the adjust-ment result and social economy pencfits are predicied, which is imporlant in long lerm planning lor reservoirs.
