摘要:

世界上碳酸盐岩储层的油气产量约占世界油气总产量的60%,但是在我国,与常规的砂岩油气藏相比,碳酸盐岩油气藏勘探开发程度较低,所以研究碳酸盐岩储层具有重大的实际意义。本文通过对川东地区石炭系碳酸盐岩储层成因机理及主控因素的研究,深刻地剖析其储层形成机理,有利于该区碳酸盐岩储层的评价与预测,为油气开采提供了重要的地质依据。在总结前人研究成果的基础上,重点从影响储层形成的主控因素——沉积相与岩性对储层发育的控制,白云岩化的作用和古岩溶作用对储层发育的控制进行了描述,以及对各个成岩阶段,不同主控因素对储层形成的机理进行了动态分析。

The production of oil and gas generated from the carbonatite reservoirs makes up 60 percent of the total oil and gas production in the world. But the exploration degree of the carbonatite reservoir is relatively lower compared with that of the conventional sandstone reservoirs in China. So the research for the carbonatite reservoir rocks has a great significance. In this paper, the formation mechanism and the main control factors for the formation mechanism of the Carboniferous carbonate reservoir rocks in eastern Sichuan area have been studied. The research on the forma-tion mechanism of the carbonatite reservoirs will be of benefit to the evaluation and prediction of the carbonatite reservoirs, and also will provide an important geological basis for the exploration of oil and gas in the study area. Based on the research of predecessors’ research findings, we focused on the description of the main control factors, including sedimentary facies and lithology, dolomitization and palaeo-karstification. In addition, we also analyzed the dynamic for the influence of various diagenetic stages and main control factors on the formation mechanism of the Carboniferous carbonate reservoir rocks in eastern Sichuan area.
