储采比与油田稳产关系--以中石化探区为例

Relationship between reserve-production ratio and stable production:an example from SINOPEC's producing oilfields

为了全面认识储采比与油田稳产的关系,分析了目前有关储采比与油田稳产相关的认识或观点形成的背景及依据,通过对中石化200个已开发油田的分析,从中筛选了38个油田对其分油田类型进行了储采比统计分析,同时进行了稳产期末储采比的理论推导。研究表明,储采比与油田稳产的关系决定于油田的开发阶段、油田类型、开发政策等,而不能单纯由储采比的大小来判断是否能够稳产。

Currently, the common understanding of reserve-production ratio is contrary to the actual production in oilfields. To understand the relationship between reserve-production ratio and stable production, we analyze the existing views and their background and basis. We select 38 out of SINOPEC＇ s 200 producing oilfields and make a statistics on reserve-production ratio according to the type of oilfields. Their hypothetical reserve-produc- tion ratio at the end of stable production is also deduced. The results show that the relationship between reserve- production ratio and stable production depends on the development phase of an oilfield, oilfield type and the development policy. Whether an oilfield can keep stable production cannot be judged only from reserve-produc- tion ratio.
