指出英买力低凸起奥陶系古潜山碳酸盐岩主要由灰色、深灰色、灰白和灰褐色的生屑灰岩、砂屑灰岩、白云岩、瘤状灰岩和泥晶灰岩等组成,自上而下分为泥质灰岩段、灰质泥岩段、瘤状灰岩段、生屑灰岩段、燧石泥晶灰岩段、泥晶灰岩夹粒屑灰岩段、云质灰岩段和灰质云岩段等8个岩性段;储层分为暴露浅滩型、岩溶型、深埋热液白云岩型、古风化壳潜山型和构造裂缝型储层等5种不同成因类型;在长期的漫长地质演化过程中主要经历了海水成岩环境、混合水成岩环境、蒸发海水成岩环境、早期大气淡水成岩环境、埋藏成岩环境、晚期大气淡水成岩环境和再埋藏成岩环境等。

The yingmail low heave carbonic buried hill includes gray, dark-gray, offwhiteand dust-colour biologic, sandstonic, strumae, mud carbonate And dolomite. It isseparated eight lithology sects from up to down:Mud carbonate, gray matter mud,strumaed carbnote, biologic carbnote, flint carbnote, mud and biologic carbonate, dolomitic carbnote, carbnotic dolonate.It is separated five mineralization types:exposure bank, harst, deep buried dolomite, paleo-carbonate buried hill, tectonic-rimose and so on. In the long geologic evolvement,it lived seawater mineralization condition, mixed water mineralization condition, vaporized seawater mineralization condition, forepart fresh water mineralization condition, buried mineralization condition.
