碳酸盐岩礁滩储层的形成和发育规律——溶蚀模拟实验
Formation and Development of Reef-shoal Reservoir:Extending Knowledge From the Dissolution Experiment
摘要
Abstract
By means of dissolution experiment of meteoric water on the limestone with different fabric of Upper Ordovician Lianglitage Formation in Tazhong area, Tarim Basin, the developmental pattern and controlling factors of reef-shoal reservoir have been concluded, as following: (1)Rock fabric and primary porosity exert significant effects on the dissolution of reef-shoal rock, in which grainstone tends to be dissolved with highest efficiency;(2)Lithofacies is an important factor controlling the formation and development of reef-shoal reservoir, and mostly for grainstone; (3)Primary porosity, which could be elevated by contemporaneous dissolution and long term dissolution, is essential for the extent of reef-shoal reservoir, and determines the extent of late modification. It is pointed out that attentions should be paid to the analysis on the late superimposed modification during the exploration of Lianglitage Formation in intraplatform zone; whereas during the development of reservoir in platform margin, the characterization of reservoir heterogeneity caused by the combination of lithofacies, sequence boundaries, and syndepositional faults should be highlighted.关键词
