预测油田天然气可采储量的方法

The Method of Forecasting Recoverable Reserves of Natural Gas in the Oilfield

油田中的天然气，包括气顶气和溶解气，是重要的资源和能源。因此，在计算和上报原油地质储量和可采储量的同时，也必须计算和上报油田中天然气的地质储量和可采储量。“本文基于物质平衡原理和文献［1，2］的成果，对于未饱和油藏和饱和油藏，不同驱动类型和开发阶段，提出了预测油田中天然气可采储量的方法。

Natural gas including cap-gas gas and solution gas in the Oilfield, are also important resources and energy. Therefore, the original gas in place (OGIP ) and the initial natural gas reserves must be sirnultaneously calculated and reported to a higher body with its original oil in place (OOIP) and initial oil reserves. Based on the material balance principle and the results of references[ 1, 2 ], the methods of forecasting initial natural gas reserves for the undersaturated and the saturated oilfields in different drive types and development stages are proposed in this paper.
