储量动用状况定量化表征研究

探讨油藏储量动用状况定量化表征的原理及方法。从质量管理与控制的角度,提出了利用油藏阶段采收率与最终采收率的比值来定量表征储量动用状况的新概念——储量动用质量。运用这一新概念,分析评价了胜利断块油藏的储量动用状况,并建立了以储量动用质量百分数为0,40%)、40%,60%)、60%,70%)、70%,90%)、90%,100]5个区间作为衡量储量动用状况较差、差、达标、良、优5个级别的评价标准。通过计算,得出胜利断块油藏储量动用质量为67.5%,为"达标"级。研究表明,储量动用状况定量化表征不仅取决于油藏开发工作的质量,而且还取决于油藏储量的质量(品位)。

Research on quantitative characterization of evaluating reserves employing status

This paper studies the theorem and method of the quantitative characterization to evaluate the reserves employing status.According to the theory management and control of quality,a new concept(reserves employing qualities) is used to analyse and evaluate the reserves employing status,and its numerical value is equal to the ratio of staggered recovery and final recovery.Using the concept,the reserves employing status of the fault block oil reservoirs of the Shengli Oilfield is calculated and evaluated.With the analyzing and evaluating results,the evaluation standard is achieved by using the percentage of reserves employing quality.The percentage is divided into 0%,40%),40%,60%),60%,70%),70%,90%),90%,100%].And each numerical value represents worse,bad,good,better,and best status.Through computing,the reserves employing quality is equal to 67.5%.The research demonstrates that the quantitative characterization of evaluating the reserves employing status lies not only on the quality of the development work but also on the quality of the reserves in the oilfield.
