摘要：

气藏物质平衡方程式可以确定气藏的原始地质储量,是气藏工程中计算储量的重要方法。由于含硫气藏的特殊性,如硫析出形成硫沉积等,而目前在用物质平衡方程计算定容含硫气藏原始储量时,仍然采用原有的定容气藏物质平衡方程,因而忽略了硫沉积造成的差异,会对计算结果造成一定的影响。本文针对含硫气藏的特殊性,如硫析出形成硫沉积等问题,基于物质平衡原理,考虑硫沉积造成的差异,建立起新的定容含硫气藏物质平衡方程。并应用于定容含硫气藏储量计算,计算结果表明新方程计算结果更加可靠。

Abstract:

The material balance equation for gas reservoir can be used in the calculation of the original gas in place(OGIP) of reservoirs and has been widely adopted in the calculations of gas reserves.However,the equation is not suitable in the calculation for the reserves of constant-volume sour gas reservoirs due to such facts as sulfur may precipitate and form depositions and etc.The neglect of differences caused by sulfur deposition would distort the results to some extent in the calculation of OGIP in constant volume gas reservoirs.This paper levels at such features of sour gas reservoirs and formulates a new material balance equation,which takes the diffe-rences into consideration.The application of the new equation to constant-volume sour gas reservoirs yields positive results and shows that it is more reliable.

Key words: constant-volume sour gas reservoir, hydrogen sulfide, material balance, reserve calculation
