龙岗地区礁滩储层有效性评价

龙岗地区二叠系长兴组的生物礁、三叠系飞仙关组的鲕粒滩都是很有潜力的礁滩型储层，根据储层特点将其分为4 种类型：飞三—飞一上部灰岩孔隙型储层，飞三—飞一中部云岩溶孔型储层，长兴组灰岩孔隙型储层，长兴组云岩孔洞、裂缝–孔洞型储层。通过薄片、压汞、MDT 测试、电成像、斯通利波等综合评价4 套储层的有效性，认为长兴组云岩孔洞、裂缝–孔洞型储层有效性最好，飞三—飞一中部云岩溶孔型储层其次，飞三—飞一上部灰岩孔隙型储层以及长兴组灰岩孔隙型储层有效性最差，较难形成工业产能。

Bank Reef Reservoir Effectiveness Evaluation in Longgang District

Permian Changxing reefs and Triassic Feixianguan oolitic beach in Longgang district is potential bank reef reservoir. According to the reservoir characteristics,they are divided into four types:Fei3—Fei1 upper limestone porosity reservoir, Fei3—Fei1 middle dolomite dissolved pore reservoir,Changxin limestone porosity reservoir,and Changxin dolomite cavern or fracture-cavern reservoir. We comprehensively evaluate the effectiveness of these reservoirs by means of thin slice,mercury penetration,MDT,FMI,Stoneley wave and other methods. The study shows that the effectiveness of Changxin dolomite cavern or fracture-cavern reservoir is the best,and second best is Fei3—Fei1 middle dolomite dissolved pore reservoir. The effectiveness of Fei3—Fei1 upper limestone porosity reservoir and Changxin limestone porosity reservoir is poor,which is not likely to have become industrial capacity.
