【摘要】：深层—超深层白云岩储集层是未来油气勘探的重要领域和目标,是潜在的优质油气储集体或储集层。查明白云岩的成因、孔隙发育与保存机理以及流体性质与演化路径,建立符合实际地质状况的储集层地质模型,对于预测深层—超深层白云岩储集层的分布规律是非常重要的。疏理了白云岩成因的几个核心问题的现状与发展趋势,指出了白云石化作用模式的演变过程和发展方向,提出了建立深层—超深层白云岩多阶段动态演化模式应考虑的问题。中国三大克拉通盆地(四川盆地、塔里木盆地和鄂尔多斯盆地)深层—超深层赋存丰富的白云岩,并且已经有一些重要的油气发现,为开展深层—超深层白云岩油气勘探提供了好的机遇,但深埋藏、多期构造改造、叠加和复杂的流体演化历史也是此项研究重要的挑战。
[Abstract]:Deep-ultra-deep dolomite reservoir is an important field and target of oil and gas exploration in the future. It is a potential high-quality oil and gas reservoir or reservoir. The origin, pore development and preservation mechanism, fluid properties and evolution path of dolomite are investigated. It is very important to establish reservoir geological model in accordance with the actual geological conditions to predict the distribution law of deep-to ultra-deep dolomite reservoir. The present situation and development trend of several core problems of dolomite genesis are discussed. The evolution process and development direction of dolomitization model are pointed out, and the problems to be considered in establishing the multi-stage dynamic evolution model of deep-to ultra-deep dolomite are put forward. Deep-ultra-deep dolomite is abundant in Tarim basin and Ordos basin, and some important oil and gas discoveries have been made, which provides a good opportunity for oil and gas exploration in deep to ultra-deep dolomite, but it is deeply buried. Multi-stage structural transformation, superposition and complex fluid evolution history are also important challenges in this research.
