摘要
碳酸盐岩是非常重要的一类储层 ,应用层序地层学分析方法对碳酸盐岩有效储层进行预测是实用而有效的 ,地震参数分析方法是有效储层预测的补充方法。总体上极为致密的碳酸盐岩中 ,溶蚀性孔洞是有效储层形成的关键因素 ,而溶蚀性孔洞的发育和沉积相密切相关。在下侏罗统大安寨段湖相介屑灰岩储层的预测中 ,层序地层学储层预测方法成功地得到了运用。使用同样方法对SZ地区下三叠统飞仙关组鲕滩储层、石炭系黄龙组白云岩储层的展布作了全面的分析和预测 ,预测结果基本为钻井所证实 。
Carbonate rock is an important kind of reservoir.The discrimination of effective pay provides a foundation for prediction of hydrocarbons in carbonate reservoir.Supplemented with seismic attributes for reservoir description, sequence stratigraphy methods have proved to be effective ways to discriminate reservoirs. Corroded pores, which are closely related to depositional environment, are vital to the formation of effective reservoirs in tight carbonate rocks. Sequence stratigraphy methods have been successfully used in the determination of Daanzai biogenic limestone reservoir. The same methods were adopted in the prediction of the Lower Tertiary oolite reservoir of Feixianguan Formation and the Carboniferous dolomite reservoir of Huanglong Formation in SZ area. The predicting results have been confirmed by drilling.
