【摘要】：常规油气的不断减少,使得非常规油气在能源方面成了重要的研究领域。作为非常规油气中的代表,页岩油的富集程度及可采资源量评价研究就变的越来越重要。大民屯凹陷区块就有丰富的非常规油气。本文根据辽河油田提供的关于大民屯凹陷沙河街组的老井数据进行研究分析,对该区块进行了页岩油气资源评价。评价的方法有很多种,根据分析结果,对评价方法作了一一对比,针对大民屯凹陷筛选出了最适合的评价方法-体积法,并根据数据确定了页岩油气资源分级评价标准。分析页岩油气资源分级评价关键参数;依据老井数据绘制不同级别页岩厚度、TOC、S1、氯仿沥青“A”等值线图,进行页岩油气资源分级评价;建立TOC、S1、氯仿沥青“A”模型,做出页岩有机非均质性测井评价。通过对大民屯凹陷沙河街组页岩油研究和评价,划分有利目标层段,对目标层段的页岩油气可动、可采资源进行了评价。大民屯凹陷沙三四段基本没有可动、可采的资源量约;沙四上可动资源量约为0.13亿吨;沙四下可动资源量约为0.31亿吨。大民屯凹陷页岩油可采资源量约为0.11~0.14亿吨。沙四下为大民屯凹陷的有利区,主要集中在沈223和沈224两口井附近。
[Abstract]:With the decrease of conventional oil and gas, unconventional oil and gas has become an important research field in energy field. As a representative of unconventional oil and gas, the evaluation of shale oil enrichment and recoverable resources becomes more and more important. The area of Damingtun depression is rich in unconventional oil and gas. Based on the old well data provided by Liaohe Oilfield about Shahejie formation in Damingtun depression, the shale oil and gas resources in this block are evaluated. There are many kinds of evaluation methods. According to the analysis results, the evaluation methods are compared one by one, and the most suitable evaluation method-volume method is selected for Damingtun sag, and the criteria for evaluating shale oil and gas resources are determined according to the data. This paper analyzes the key parameters of shale oil and gas resource classification evaluation, draws the map of different grade shale thickness and chloroform asphalt "A" isoline according to the old well data, and establishes the TOC S1 and chloroform asphalt "A" model. Shale organic heterogeneity logging evaluation was made. Through the study and evaluation of shale oil of Shahejie formation in Damingtun depression, the favorable target zone is divided, and the movable and recoverable shale oil and gas resources of target formation are evaluated. The third and fourth member of Sha in Damingtun sag has no movable resources, and the recoverable resources are about 13 million tons, 31 million tons and 31 million tons respectively. The recoverable amount of shale oil in Damingtun depression is about 0.11 ~ 14 million tons. Shasixia is a favorable area in Damingtun sag, mainly located near Shen223 and Shen224 wells.
