摘　　要：滨里海盆地东缘中区块石炭系KT-Ⅰ段发育中高孔隙度白云岩优质储层,主要储集空间为溶蚀孔隙、次生裂缝和孔洞。研究发现,部分中高孔隙度储层显示储层物性及含油性好,但实为无效储层。提出利用常规测井资料与岩心标定识别碳酸盐岩储层中的裂缝和溶洞技术以及储层有效性评价的具体方法,有效解决了复杂碳酸盐岩储集层识别的问题。该方法实际应用取得了显著的地质效果。The reservoir of the KT- Ⅰof centre block in the eastern margin of Pre-caspian basin in Kazakhstan is a carbonate reservoir with moderate to high porosity. High quality reservoirs develop mostly in dolomite rocks, and have fractures and vugs. Log data indicate that some carbonate reservoirs with moderate to high porosity show good reservoir properties and oil- bearing properties, but are invalid reservoirs. By using conventional log data and core calibration techniques to identify the fractures and vugs as well as evaluation of reservoirs＇ validity, the authors effectively solve identification problems of complex carbonate reservoir. This method obtains remarkable geology results in practical application.
