东营利津洼陷沙四段页岩含油气量测定及可动油率分析与研究

摘要

A new analysis method for all the light liquid hydrocarbons and heavy hydrocarbons in shales was founded, and a creative testing means for movable oil amounts in shales was also formulated. The oil and gas con-tents, liquid hydrocarbon characters and movable oil amounts of shales in the 4th member of the Shahejie Forma-tion in the Lijin subSag of the Dongying Sag were studied. The results showed that the gas content of the Es4 shales is relatively lower, and the shale oil is a favorable exploration target. The light hydrocarbon ratio and mov-able oil amount are relatively higher, showing good prospects for shale oil exploration in the 4th member of the Shahejie Formation in the Lijin subSag.%建立了页岩内含气量、液态轻质油、重质油的系统测定方法及页岩可动油实验方法，并对东营凹陷利津洼陷古近系沙河街组沙四段页岩样品的含气量、含液态油量、液态油性质及可动油率进行研究。研究结果表明：利津洼陷沙四段页岩含气量较低，勘探以页岩油为主。而液态油中含有较高的轻质油含量，并且具有较高的可动油比例，有利于利津洼陷沙四段页岩油的勘探开发。
