本文以荷兰的一个气田为例,阐述预测气田的横向延伸及气层孔隙度所使用的定性分析法。这是一项包括地质、地球物理和石油物理技术的多学科综合研究工作。过去十年中,地球物理工业为利用地震振幅测量、逆地震记录或“合成声速测井”以及地层模型预测岩相、孔隙度及其充填物作了相当大的努力。通常,这些研究涉及了碎屑岩或简单的碳酸岩沉积序列,此时岩石体积密度或地震反射资料的影响是忽略不计的。预测最佳评价井位的碳酸岩油藏是在蔡希 In this paper, a gas field in the Netherlands is taken as an example to illustrate the qualitative analysis method used to predict the lateral extension of gas fields and the porosity of gas reservoirs. This is a multidisciplinary and comprehensive study that includes geophysical, geophysical and petroleum physics. Over the past decade, the geophysical industry has made considerable efforts to predict lithofacies, porosities and fillings using seismic amplitude measurements, inverse seismograms or “synthetic sonic velocity logs” and stratotype models. Often, these studies involve clastic or simple carbonate sedimentary sequences where the effect of rock bulk density or seismic reflection data is negligible. Carbonate reservoirs that predict the best evaluation of well locations are at Cai Xi
