【摘要】：在詳細分析前人研究成果的基礎(chǔ)上,運用高分辨率層序地層學方法,收集巖心、測井曲線、地震剖面等資料,開展層序地層和油層細分對比等工作,將扶楊油層共劃分為39個小層。本論文以砂體展布特征、重礦物和地層傾角資料的統(tǒng)計分析為依據(jù),緊密結(jié)合區(qū)域構(gòu)造背景展開了朝長地區(qū)物源判識研究,認為研究區(qū)內(nèi)扶楊油層主要受東南和西南兩個物源方向影響。沉積環(huán)境與沉積相是控制砂巖儲集體發(fā)育與分布的先天性地質(zhì)因素,本文基于巖心、錄井和測井、和分析化驗等資料對研究區(qū)沉積相及其分布進行了精細分析,指出該區(qū)塊主要發(fā)育曲流河和三角洲沉積。并在研究區(qū)識別出分流河道、水下分流河道、邊灘、席狀砂等8種沉積微相類型,建立巖心—測井相模式,對主力油層砂體分布進行了詳細研究。
[Abstract]:On the basis of the detailed analysis of the previous research results, the high resolution sequence stratigraphy method is used to collect core, log curves, seismic profiles, and to carry out the work of sequence stratigraphy and reservoir subdivision and correlation. The Fuyang reservoir is divided into 39 sublayers. Based on the distribution characteristics of sand bodies, the statistical analysis of heavy mineral and stratigraphic dip data, and in close combination with the regional tectonic background, a study on the identification of source materials in Chaokang area has been carried out in this paper. It is considered that the Fuyang reservoir in the study area is mainly affected by two source directions: southeast and southwest. Sedimentary environment and sedimentary facies are the congenital geological factors controlling the development and distribution of sandstone reservoir. Based on the data of core, logging and logging, and analysis, the sedimentary facies and their distribution in the study area are analyzed in detail. It is pointed out that the meandering river and delta deposits are mainly developed in this block. Eight types of sedimentary microfacies, such as distributary channel, underwater distributary channel, edge beach and sheet sand, are identified in the study area. The core logging facies model is established and the distribution of the main reservoir sand body is studied in detail.
