摘要: 深盆气藏是一种形成条件、成藏机理和分布规律完全不同于常规气藏的特殊气藏,这种气藏形成和保存必须满足力平衡和物质平衡条件,依此条件给出了确定深盆气藏分布范围的数值计算方法.根据深盆气藏形成和保存的动态特征,将三维地史数值模拟方法在国内首次应用于深盆气藏形成机理及分布规律的研究,即在盆地模拟的基础上,定量地研究了储层形成圈闭的动态过程、各地史时期源岩生烃和排烃特征、及两者之间的耦合关系,计算了不同地史时期深盆气藏的分布范围和储量.用基于此模拟方法开发的三维盆地数值模拟系统,对深盆气藏分布范围的动态演化过程进行了定量研究,并应用于预测吐哈盆地深盆气藏分布范围.

Abstract: The formation conditions and distribution principles of deep-basin gas reservoir are different from those of the typical hydrocarbon habitat.The formation and conservation of the gas reservoir must meet the force and substance balance conditions.A numerical simulation method for the system of three-dimensional basin was developed in order to derive the data of geology history from the present data.The numerical result is more exact for optimizing the parameters of the initial porosity and compress coefficients.The mathematical model and algorithm were applied to the research of dynamic distribution and prediction of accumulation quantity of deep basin gas.The numerical results fit well with the practice of Turpan-Hami Basin.

Key words: deep-basin gas, force balance, substance balance, basin numerical simulation, dynamic distribution, quantitative research
