摘要
天然气或凝析气的偏差因子在计算天然气储量过程中有着重要作用 ,在编制气田开发方案以及气藏动态分析、天然气加工、储存运输等方面也有广泛的运用。目前 ,确定气藏偏差因子的方法主要有实验测定、公式计算和图版法确定 ,而公式计算又可分为经验公式计算和状态方程计算两类。本文从实验出发 ,分别对一般天然气和非烃含量较高的天然气作了大量实验 ,总结了天然气偏差因子的一些变化规律 ,并与经验公式和软件计算的结果进行了比较。
The deviation factor of natural gas or condensat e gas plays an important role in estimating gas reserves and is widely applied t o the gas field development plan compilation and gas reservoir performance analy sis as well as the processing,storage and transportation of natural gas.At prese nt,the methods of determining the deviation factor of gas reservoir are mainly e xperimental determination,formula calculation and typical curve graphic determin ation and the formula calculation may be divided into two categories,i.e.empiric al equation calculation and state equation calculation.In the paper,by means of a large number of experiments finished up for the common natural gas and the nat ural gas with high nonhydrocarbon content respectively,some change rules of the deviation factor natural gas are summarized and the experimental results are con trasted with the results calculated by empirical equations and software.
