【摘要】 火山口的识别是火山岩气藏开发的热点和难点,虽然目前已有很多学者开展了研究工作,但因所用资料的局限,火山口识别结果的可靠性问题没有得到很好地解决。通过综合运用地震、测井、钻井取心、地质、气井生产动态资料,采用地震剖面形态特征分析、常规测井信息融合、构造岩浆流向分析和生产动态分析等多信息综合识别技术,研究了一套火山口有效识别方法。以松辽盆地南部火山岩气藏火山口为例,识别出长岭七个火山口,英台三个火山口,近火山口相的三口气井产液量证明近火山口相储层发育,物性好。这种多信息综合识别方法应用效果较好,解决了火山岩气藏井位部署的难题。更多还原

【Abstract】 The identification of the volcanic crater is difficult for volcanic gas reservoir development. Although many scholars presently have made much research, the reliability of identifying result is not well settled. Through multi-data including seismic, drilling core, geology, dynamic yield data, using the integrated technology including configuration and character analysis of seismic profile, general logging information amalgamation, flow of magma analysis and dynamic yield analysis. Taking the volcanic gas reservoir in southern Songliao basin for example, 7 craters in Changling and 3 in Yingtai have been identified. The liquid producing capacity of 3 gas wells showed that the phase near crater has better reservoir developed and better physical property. This kind of information integration method has great application effect and resolved the problem of well-site deployment for volcanic gas reservoir.更多还原
