| 摘 要： | 龙岗地区雷口坡组碳酸盐岩储层岩性复杂、岩石结构多样,储集空间复杂,储层非均质性较强,储层有效性评价是测井评价的重点与难点。在分析储层特征的基础上,运用测井资料结合岩心物性、压汞等分析资料,从储层岩性、物性、裂缝等3个方面进行储层有效性评价。研究认为,有效储层岩性以白云岩为主,颗粒云岩的有效性好于粉晶云岩;非角砾岩有效性优于角砾岩。同时,通过常规测井与微电阻率成像测井、偶极声波测井结合,更客观地评价储层岩性、物性、裂缝,进一步评价了储层有效性。

| Abstract: | The carbonate reservoir in the Leikoupo formation of Longgang area is characterized by complex lithology,diversified rock texture,complex reservoir space and severe heterogeneity.Reservoir effectiveness evaluation is critical in well logging evaluation and has been carried out in terms of lithology,physical property and fractures based on well logging,core and mercury penetration data.The research shows that dolomite is the main effective reservoir lithology,with granular dolomite better than crystalline do... |
