【摘要】：常規(guī)油氣的不斷減少,使得非常規(guī)油氣在能源方面成了重要的研究領(lǐng)域。作為非常規(guī)油氣中的代表,頁巖油的富集程度及可采資源量評(píng)價(jià)研究就變的越來越重要。大民屯凹陷區(qū)塊就有豐富的非常規(guī)油氣。本文根據(jù)遼河油田提供的關(guān)于大民屯凹陷沙河街組的老井?dāng)?shù)據(jù)進(jìn)行研究分析,對(duì)該區(qū)塊進(jìn)行了頁巖油氣資源評(píng)價(jià)。評(píng)價(jià)的方法有很多種,根據(jù)分析結(jié)果,對(duì)評(píng)價(jià)方法作了一一對(duì)比,針對(duì)大民屯凹陷篩選出了最適合的評(píng)價(jià)方法-體積法,并根據(jù)數(shù)據(jù)確定了頁巖油氣資源分級(jí)評(píng)價(jià)標(biāo)準(zhǔn)。分析頁巖油氣資源分級(jí)評(píng)價(jià)關(guān)鍵參數(shù);依據(jù)老井?dāng)?shù)據(jù)繪制不同級(jí)別頁巖厚度、TOC、S1、氯仿瀝青“A”等值線圖,進(jìn)行頁巖油氣資源分級(jí)評(píng)價(jià);建立TOC、S1、氯仿瀝青“A”模型,做出頁巖有機(jī)非均質(zhì)性測井評(píng)價(jià)。通過對(duì)大民屯凹陷沙河街組頁巖油研究和評(píng)價(jià),劃分有利目標(biāo)層段,對(duì)目標(biāo)層段的頁巖油氣可動(dòng)、可采資源進(jìn)行了評(píng)價(jià)。大民屯凹陷沙三四段基本沒有可動(dòng)、可采的資源量約;沙四上可動(dòng)資源量約為0.13億噸;沙四下可動(dòng)資源量約為0.31億噸。大民屯凹陷頁巖油可采資源量約為0.11~0.14億噸。沙四下為大民屯凹陷的有利區(qū),主要集中在沈223和沈224兩口井附近。
[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.
