摘要
根据大量岩心资料，通过地质多元统计分析，将影响砂岩储层的地质因素，包括沉积相，骨架颗粒成分，成岩作用及埋藏史等量化为沉积学参数，并研究这些参数与孔隙度的关系，从而建立了砂岩储层孔隙度预测公式，用该公式对辽东湾及埕岛地区深部地层孔隙度进行了预测，误差一般小于2％。
By means of multivariate geological statistics and based on a large amount of core data,an e-quation for predicting sandstone porosity is achieved by changing the geological factors including depositional facies,framework grain composition,diagenesis and burial history which affecting the petrophysics of sandstone reservoir into sedimentological parameters,and by studying the relationship between those parameters and porosity. This equation is used to predict the porosity of deep horizons in Liaodong Bay and Chengdao area,and the error between predicted value and measurement is generally less than 2%.
