碳酸盐岩储集层的形成碳酸盐岩含油气地层是非均质体,构成了复杂的孔隙介质:即孔隙分布的不同性质、孔隙通道的弯曲性、存在裂缝和溶洞等。它的孔隙形式有孔隙、裂缝和溶洞,在自然埋藏条件下它们充填有水、油或气。现时业已证明:在形成孔隙型储集层时,原始的岩相条件是有决定意义的。因为原始孔隙空间结构对流体的渗透性是否有利,在很大程度上取决于后来沉积过程的速度、强度和方 Formation of Carbonate Reservoirs Carbonate petroleum-bearing formations are heterogeneous and form complex pore media: different properties of pore distribution, bend of pore channels, presence of fractures and cavities. It has pores in the form of pores, cracks and caves, which are filled with water, oil or gas under natural burial conditions. It has now been proven that the original lithofacies conditions are of decisive importance in the formation of pore-type reservoirs. Because of the favorable permeability of the original pore space structure to the fluid, it depends very much on the subsequent deposition rate, strength and square
