天然气新增动用可采储量标定方法研究及其应用

CALIBRATION METHOD AND APPLICATION OF NEW ADDING RECOVERABLE RESERVES FOR NATURAL GAS

年度气藏新增动用天然气可采储量是考核生产效益的重要指标之一,但关于新增动用天然气可采储量的计算尚无明确的规定和方法,部分油公司多采用算术平均的方法,这显然是不合理的。文章从统计学的角度出发,结合四川气区的气藏地质和气藏工程特点,在对大量气藏实际地质、生产数据样本分析的基础上,研究了不同气藏类型气井无阻流量、稳定产量以及单井控制可采储量之间的相关关系,并利用它们之间的相关关系计算气藏的新增动用可采储量。该方法已成功应用于西南油气田分公司2002年、2003年、2004年度的天然气新增动用可采储量的标定及申报工作中。

The new adding recoverable reserves per year are one of the important indexes to evaluate the production benefit. But there are no clean regulations and methods to calculate the new adding recoverable reserves. It is not reasonable obviously for some oil companies to use the arithmetic average method to calculate. With statistic principle, integrating the geological and engineering features of the gas reservoirs in Sichuan area, based on the sample analysis of large real data of geology and production, the ...
