摘要:
流动物质平衡法计算储量方法简易,前提是产量稳定,但矿场井口产量经常变化,无法形成有效直线段; 即使产量保持稳定,使用流动压力计算的储量也偏低。利用物质平衡方程计算储量的关键就是要准确求取地层压力,介绍一种简易计算不同时间气藏压力的方法,利用井口压力计算井底压力,再由气井产能方程计算不同时间的气藏压力,这样无需考虑产量变化及地层压力与流压之差所导致的物性参数变化,求得的物质平衡方程线性相关程度较高,储量误差小。通过PQ区块单井控制储量两种方法计算,流动物质平衡法平均误差34.2%,说明本文计算方法简单、有效、实用。
Abstract:
The method of calculating reserves by flow material balance is simple and easy, on the premise that the production is stable, but the output of wellhead often changes, which can not form an effective straight line segment; even if the production is stable, the reserves calculated by flow pressure are low. The key to calculating reserves by using material balance equation is to accurately calculate the formation pressure. This paper introduces a simple method for calculating gas reservoir pressure at different time, calculating bottom hole pressure by using wellhead pressure, and then calculating gas reservoir pressure at different time by using gas well productivity equation. Thus, it is not necessary to consider the change of physical parameters caused by production change and the difference between formation pressure and flow pressure. The linear correlation degree of mass balance equation is higher and the reserve error is smaller. The average error of the flow material balance method is 34% by calculating the single well controlled reserves in PQ block,FL shale gas field, which shows that the calculation method in this paper is simple, effective and practical.
