提出了一种评价异常高压气藏有限封闭水体能量的新方法。此方法是在广义物质平衡方程的基础之上,结合异常高压气藏的生产动态,计算出异常高压气藏有限封闭水体的水体倍数,从而对气藏的水体能量进行评价。通过对新场气田新3井的实例计算,得出有限封闭水体的水体倍数为0.080 5。文章论证了此方法的可靠性和有效性。
A new method for evaluating the energy of a confined water body in an abnormally high pressure gas reservoir is proposed. This method is based on the generalized material balance equation, combined with the production of abnormally high pressure gas reservoirs to calculate the water body times of the limited confined water bodies in abnormally high pressure gas reservoirs to evaluate the water body energy of the gas reservoir. Based on the case study of Xin 3 well in Xinchang Gas Field, it is concluded that the water body of finite closed water body is 0.080 5. The article demonstrates the reliability and effectiveness of this method.
