【摘要】 升平深层火山岩气藏是大庆油田发现最早的火山岩气藏,经过两年多的气藏开发前期评价,对气藏的岩性岩相、储集空间类型、储层分布、流体分布规律和气藏类型等都有了深刻认识,并形成了一套火山岩气藏描述技术,即火山岩岩性岩相描述技术、测井火山岩岩性与流体性质识别技术、地震火山岩体识别技术和火山岩储集空间描述技术。利用这一整套研究技术。对该气藏进行了详细的描述,确定了火山的喷发模式、储层展布、储集空间特征及气藏类型,从而为气田开发方案的编制奠定了基础,同时也为该区的资源前景评价提供了依据。更多还原

【Abstract】 The deep volcanic gas reservoir in Shengping area is discovered in Daqing Oilfield for the first time. Some profound understandings have been achieved in lithology, lithofacies. types of reservoir space, reservoir distribution, fluid distribution, types of gas reservoirs and so on after more than two years’ prophase evaluation, and a suit of technologies have been formed, which including the description technique for volcanic lithology and lithofacies, well logging recognition technique for volcanic lithology and fluid property, the seismic recognition technique for volcanic body and the description technique of volcanic reservoir space. With the techniques, it describes in detail Shengping gas reservoirs concerning about the model of volcanic lithology and lithofacies, the types of reservoir space, space distribution of reservoirs and the types of gas reservoir, and determines the eruption mechanism of volcano, reservoir classification, reservoir space feature and gas reservoir’s type, laying a firm foundation for gas development project and also having an important significance in evaluating the resources prospect in this area.更多还原
