构控制的热液改造碳酸盐岩储层是指深部埋藏的热液(高温高压盐水)通过活跃的断层或裂缝向上侵入,在相对较浅埋藏的并有上部盖层的碳酸盐岩中发生白云石化作用以及石灰岩的淋滤作用,从而形成物性较好的油气储层。在过去的20多年中,越来越多的专家致力于构造控制的热液改造白云岩HTD(Structurally Controlled Hydrothermal Dolomite)以及淋滤石灰岩油气藏的研究。热液改造作用的产物主要包括热液改造白云岩、淋滤石灰岩以及碳酸盐岩硫矿沉积等等。在许多情况下,热液改造作用对碳酸盐岩储层的类型、几何特征、性质、以及分布有重要的影响。已经获得的并不断增多的证据表明,在全球范围内,很多碳酸盐岩储层是由热液作用而形成的,最经典的实例是西加拿大泥盆纪和密西西比纪由热液改造的白云岩和淋滤石灰岩综合作用形成的油田。
Structurally controlled hydrothermal reformation of carbonate reservoirs means that deep buried hydrothermal fluids (high temperature and high pressure brine) intrude through active faults or fractures, in relatively shallow buried upper capped carbonate rocks Occurrence of dolomitization and limestone leaching, resulting in better physical properties of oil and gas reservoirs. Over the past two decades or so more and more experts have focused on the structurally controlled Hydrothermal Dolomite (HTD) and the leaching of limestone reservoirs. Hydrothermal transformation of the products mainly include hydrothermal alteration dolomite, leaching limestone and carbonate rock deposits and so on. In many cases hydrothermal alteration has a significant effect on the type, geometry, properties, and distribution of carbonate reservoirs. The ever-increasing evidence that has been obtained shows that many carbonate reservoirs are formed by hydrothermal processes worldwide, the most classic examples being the Devonian and Mississippian age-converted white clouds from hydrothermal fluids in western Canada The combination of rock and limestone limestone formation of the oil field.
