中拐凸起火山岩裂缝型储层相态发育模式
|
摘要
石炭系火山岩油气藏是准噶尔盆地中拐凸起最为重要的油气藏类型,裂缝对储层物性具有控制作用。为了加强对中拐凸起石炭系裂缝发育规律的认识,以FMI测井资料为主,结合常规测井、录井以及岩石薄片等地质资料,建立了4种FMI测井裂缝相。通过分析不同裂缝相的配置关系,垂向划分为上部表生裂缝带和下部深埋裂缝带,对不同埋深条件下的裂缝相发育模式及对储集层的改造作用进行研究,研究结果表明,直劈溶蚀缝相是储层物性改造的主控因素,表生裂缝带则更易形成优质储集层。该研究为下一步该区寻找裂缝优势储层带提供了依据。
The Carboniferous volcanic reservoir is considered as the major hydrocarbon reservoir in the Zhongguai Bulge of Junggar Basin and the reservoir properties is dependent on fracture properties. In order to further understanding the Carboniferous fracture development in Zhongguai Bulge,FMI logging data was fully used to establish 4 FMI logging fracture facies by combining with conventional logging,mud logging,thin-section analysis and other data. Based on the configuration analysis of different fracture facies,the reservoir is divided into the upper epigenetic fracture zone and the lower deep-buried fracture zone along the longitudinal direction to study the reconstruction effect of fracture facies development patterns under different buried depth on reservoir. Research demonstrates that the reservoir property reconstruction is significantly dependent on the high-angle dissolution fracture facies. The upper epigenetic fracture facies is favorable to high-quality reservoir. This research could provide certain reference for the exploration of favorable fractured reservoirs in this area.
