油田可采储量计算方法

油田的可采储量和剩余可采储量,是油田开发建设的物质基础,因此,需要准确地加以预测和确定。根据我国多年预测、计算和标定油田可采储量的经验,结合即将修订的《石油天然气储量规范》内容的要求,经过归纳、筛选之后,文章介绍了适用于不同开发阶段,可预测油田可采储量和剩余可采储量的不同方法,其中包括类比法、相关经验公式法、驱油效率法、产量递减法、水驱曲线法和预测模型法。

Calculation Methods of Recoverable Reserves of Oilfields

Recoverable reserves and remaining reserves of oilfields are material basis of oilfield development and construction. So it is necessary to accurately forecast and determine them. Based On our experience in forecasting, calcuating and calibrating recoverable reserves of oilfields, and requirements in "Standards of Oil and Gas Reserves" to be revised, this paper presents different methods for forecasting recoverable reserves and remaiming reserves of oilfields following induction and sifting, which can be applied to different stages of oilfield development. These methods include analogical method, correlation method, displacement efficiency method, production decline mehod, water drive curve method and forecast model method.
