| 摘 要： | 海相碳酸盐岩储层多类型及非均质性强的特点,决定了其油气聚集带与以往陆相盆地碎屑岩油气聚集带的控制因素有显著差异,碳酸盐岩的油气聚集并不是简单地受二级构造带的控制。通过分析塔里木盆地已发现碳酸盐岩油气藏,其储层发育受大气淡水风化淋滤作用、沉积作用及各种成岩作用、深部流体改造作用等因素的控制。据储层成因类型及其横向分布特征,将塔里木盆地碳酸盐岩油气聚集带划分为:不整合与古风化壳型、生物建造礁-滩型、白云岩内幕型及深部流体改造型。不同类型的碳酸盐岩油气聚集带主要分布于塔北隆起、塔中隆起及巴楚断隆等古隆起的不同部位。由于不同碳酸盐岩油气聚集带上储集层成因机制不同,导致其储集空间、储集性能、油气藏类型及分布等均有所不同。

| Abstract: | Diversified characteristics and anisotropism of marine carbonate reservoirs result in the fact that the controlling factors of hydrocarbon accumulation zones are different from that of the clastic rocks in the traditional nonmarine basin. Hydrocarbon accumulation in carbonate is not simply controlled by the secondary structural zone. Analysis of discovered carbonate reservoirs in the Tarim basin shows that development of the reservoirs is controlled by the weathering leaching process of atmosphere freshwater, sedimentation, many types of diagenesis, alteration of deeply fluid. According to the genetic type and the lateral distribution characteristics of reservoirs, the hydrocarbon accumulation zones in the Tarim basin are divided into four types: unconformity and paleoweathering crust, organic buildup reef-bank, inner dolomite, and deep fluid alteration type. Different types of carbonate hydrocarbon accumulation zones are mainly distributed in different parts of many paleouplifts, such as the Tabei uplift, Tazhong uplift, Bachu fault uplift. Because of different genetic mechanisms of reservoirs in different hydrocarbon accumulation zones of carbonate, the reservoir space, reservoir capability, hydrocarbon reservoir type and their distribution are different in general. |
