摘　　要：动态储量评价是气藏开发过程中一项十分重要且具有挑战性的工作,也是高效开发的关键技术之一,国内外许多专家学者在气藏动态储量计算方面做了大量的研究工作,并提出了许多评价方法。超深层高压气藏具有基质致密、裂缝发育等特点,动态储量往往很难采用一种方法准确评价。系统分析了经典两段式、线性回归、非线性回归、典型曲线拟合等4类深层高压气藏动态储量评价方法,总结讨论了各种方法的适用条件。以K气藏为例,开展了动态储量计算,结合K气藏的地质特征及生产实际,评价优选出4种较为准确的计算方法,为气藏合理开发技术政策的调整提供依据。Dynamic reserve evaluation is a very important and challenging task in the process of gas reservoir development,and is also one of the key technologies for efficient development.Many experts and scholars at home and abroad have done a lot of research work on the calculation of dynamic reserves in gas reservoirs,and have proposed many evaluation methods.Ultra-deep high pressure gas reservoirs have characteristics such as dense matrix and well developed fractures,and the dynamic reserves are often difficult to be accurately evaluated using one method.Four types of dynamic reserve evaluation methods for deep high-pressure gas reservoirs,including classical two-stage formula,linear regression,non-linear regression,and typical curve fitting,are systematically analyzed,and the applicable conditions of various methods are summarized and discussed.Taking the K gas reservoir as an example,the dynamic reserve calculations are carried out,and four more accurate calculation methods are evaluated and selected in the light of the geological characteristics and production practice of the K gas reservoir,providing a basis for the adjustment of the technical policy of reasonable gas reservoir development.
