【摘要】 徐深气田的发现带来了大庆油田以气补油的契机,但该气田89%的天然气储量储存在火山岩中。受喷发期次、剥蚀改造等影响,火山岩储层具有孔、缝相结合的复杂储集空间特征,裂缝的发育对火山岩储层的连通性、渗流性起着重要的作用。通过应用野外观测、岩心描述、测井综合解释和地震预测方法对火山岩储层裂缝的密度、开启程度、延伸方向等特征进行综合研究,总结了徐深气田裂缝发育特征。更多还原

【Abstract】 The discovery of Xushen gas field is an important chance of making up lost oil by gas,but 89% natural gas comes from volcanic reservoirs in the gas field.Volcanic rock reservoir has complex reservoir space features of porosity and fracture influenced by eruption period,erosion and so on.Development of fracture plays an important role in connectivity and filtering flow of volcanic reservoir.Density,open degree,extension direction of fracture are comprehensively studied by using field obsevation,core description,comprehensive log interpretation and seismic prediction methods and then fracture development feature of Xushen gas field is summarized.更多还原
