【摘要】 辽西凹陷的勘探程度较低,主要在于沉积模式认识不清。本文通过碳酸盐岩沉积分布特征的研究,总结了湖相碳酸盐岩的沉积模式,在沉积模式的指导下,针对不同类型碳酸盐岩沉积特征的差异性,结合三维地震资料和钻井资料,分别利用地质统计及岩性反演等有效储层预测方法,预测了碳酸盐岩储层的分布。勘探证实,预测成果与实钻结果吻合较好,取得了明显的应用效果。更多还原

【Abstract】 The exploration maturity in Liaoxi Depression is low,the main reason is that the sedimentary pattern is not clearly understood. Through studies on distribution characteristics of the carbonate the sedimentary pattern was summarized for the lacustrine carbonate in this paper,under the direction of the sedimentary pattern,regarding the difference among distribution characteristics for different types of carbonate,the distribution of carbonate reservoir was predicted by integrating 3D seismic data with drilling data and by utilizing geological statistics,lithology inversion and other effective reservoir prediction methods respectively. The exploration proved that prediction results and drilling results matched well,and obvious application effects were achieved.更多还原
