油田经济可采储量确定方法研究

为了科学准确地研究计算油田的经济可采储量，文中在总结国内外研究的基础上，结合辽河油田的地质开发特点和我国现行的财税制度，并参照中国石油天然气集团公司的统一要求，以现金流通法为主要方法，进一步研究提出了经济极限法（经济极限含水法和经济极限油汽比法）、经济开采法、经济极限井网密度法（交汇法和单井控制储量法）三种经济可采储量计算方法，初步形成了适合辽河油田特点的经济可采储量确定方法系列。为了便于利用，笔者根据各种方法的基本原理和实用条件，进行了归类分析；通过对辽河油田不同类型油藏的实际计算，证实这些方法是切实可行的

ESTIMATION OF THE ECONOMICALLY RECOVERABLE RESERVE OF AN OILFIELD

In this paper, the authors proposed three methods of calculating the economically recoverable reserve of an oilfield. These methods include: economic limitation method ( limiting water-cut and limiting GOR ), economic recovery method and economic limit well density method. The methods were developed on the basis of analyzing available reserve estimation methods, taking into consideration the geological characteristics of Liaohe oilfield and the accounting and taxation system in China. These methods have been used by the authors to calculate the reserves of different pools in the oilfield, and the results have confirmed the methods' validity.
