摘要
在广泛地面调查、井下观测和大量室内资料综合分析基础上,对沉积环境、储层特征及其对储层发育的影响因素等方面作了研究。本区下古生界储层有三大类,6种有效储集空间,以奥陶系为最发育,储层的形成、发育和保存与沉积环境、成岩作用关系密切,并由此对有利储层分布作了探讨。经初步研究,有五套储盖组合。
Based on a comprehensive analysis of results of extensive surface geological survey, subsurface data and a large amount of in-house data, this paper gives a discussion on depositional environments, reservoir characteristic and factors affecting the development of reservoir rocks, etc. There are three types of reservoir and six kinds of effective reservoir pore space in Lower Paleozoic of this area, and Ordovician system is the most developed one. The formation development and preservation of reservoir rock are closely related to the depositional environment. Furthermore, favourable areas for reservoir distribution are discussed. A preliminary study suggests that there are five reservoir cap rock association.
