摘要
近年来,四川盆地中部地区勘探取得了突破性的成果.二-三叠系礁滩盐岩储层成为重点研究领域,为了配合二-三叠系碳酸盐岩储层的油气分布规律的研究,需要对重点区域的二-三叠系进行测井精细解释.通过多矿物模型的计算方法、储层流体判别图版法来对储层进行分析,从而对储层进行测井解释.发现其主要储层位白云岩段,并且在川中三维地区稳定分布,主体厚度在5～10m之间.为四川盆地雷口坡组的油气分布规律提供了支撑.
Abstract
In recent years,breakthrough achievements have been made in exploration in the central region of the Sichuan Basin.The Permian reef beach salt rock reservoir has become a key research area.In order to cooperate with the study of the oil and gas distribution pattern of the Permian carbonate rock reservoir,it is necessary to conduct fine logging interpretation of the Permian in the key area.By using the calculation method of multiple mineral models and the reservoir fluid discrimination chart method,the reservoir can be analyzed for logging interpretation.It was found that its main reservoir is the dolomite section,which is stably distributed in the three-dimensional area of central Sichuan,with a main thickness ranging from 5-10m.This provides support for the oil and gas distribution pattern of the Landmine Mouth Slope Formation in Sichuan Basin.
