【摘要】 为对大湾气藏有效储层做出准确评价,对大湾气藏做了大量的研究工作。通过对大湾气藏的岩性、物性、电性和含油性进行研究,进一步分析其相互之间的关系,建立解释标准后,对大湾气藏储层进行精细解释,进一步分析其纵向和横向的展布特征,并与普光主体气田进行对比,对大湾气藏的赋存特征有了更明确的认识。有效储层埋深与地震分析相比对,二者相符合,为地震解释提供了测井方面的有利证明,同时也说明气藏受岩性和构造的双重控制。更多还原

【Abstract】 Researches were conducted on Dawan Gas Reservoir to accurately evaluate the effective reservoirs of Dawan Gas Reservoir.Through researching the lithologic characteristics,physical characteristics and electric property of the reservoir,the relationship between them was analyzed.After the interpretation standard was established and accurate interpretation was performed on Dawan Gas Reservoir,its vertical and horizontal distribution characteristics was further analyzed and compared with that of Puguang Gas Reservoir,the characteristics of Dawan Gas Reservoir are clearly recognized. Comparing with the seismic analysis,the depth of the effective reservoirs is the same. The research provides a guidance of the seismic analyses.It also shows that the gas reservoir is controlled by two factors of lithology and structure.更多还原
