【摘要】 预测异常高压气藏产能动态时不能忽略综合压缩系数。如果气藏工程计算中缺乏综合压缩系数实验资料或确定的方法不当 ,可能大大影响预测结果的精度。在考虑将岩石压缩系数作为压力函数的基础上 ,用实测岩石压缩系数预测了储集层中不同黏土含量和不同边、底水规模的异常高压气藏和实际的KL2异常高压气藏的开采动态。所采用的岩石、地层水压缩系数及边、底水的处理方法 ,可用于预测异常高压气藏产能。更多还原

【Abstract】 Accuracy of the formation and water compressibilities used in productivity prediction of abnormally pressured gas reservoir significantly influences the prediction results. Considering the formation clay content variety and the bottom water size this paper predicted the recovery performance of abnormally pressured gas reservoir KL2 by using formation compressibility measured in laboratory. The methodology dealing with the formation and water compressibilities and bottom water size could be applied in abnormally pressured gas reservoir performance prediction.更多还原
