川中乐山—龙女寺古隆起奥陶系古岩溶发育地质因素分析
The Geological Condition Analysis of Ordovician Paleo-kastification of Leshan-longnvsi Paleohigh in Central Sichuan
【摘要】 分析了岩溶发育的7种地质因素,即岩性、地层结构、地质构造、古地貌、古气候、先存孔洞系统以及埋藏期的后期改造等。结果表明,研究区域适宜大规模风化壳岩溶作用的发生以及岩溶型储层的发育。
【Abstract】 This paper summarizes seven kinds of geological factors advantageous for karstification,such as the lithology,the strata framework,the geological strature,the paleo-relief,the paleo-climate,the former pore space system and the later reconstruction in embedding period.This research demonstrates that this area is suitable for the development of large scale weathering crust and karstic reservoirs.
