【摘要】：肅寧地區(qū)位于饒陽凹陷中部,緊鄰河間富油洼槽區(qū),剩余油氣資源豐富,是油氣預(yù)探的重點靶區(qū)。該區(qū)構(gòu)造背景好、油源條件優(yōu)選,但受遠離物源區(qū)和古地貌影響,沉積相展布復(fù)雜,儲層分布變化較快。由于對沉積相平面展布及砂體的空間展布規(guī)律認識不清,已經(jīng)嚴重制約的油氣勘探工作。為此,加強沉積體系與砂體預(yù)測研究成為了本區(qū)地層巖性油氣藏勘探的關(guān)鍵。本論文期望通過研究饒陽凹陷肅寧地區(qū)古近系(Es1~Ed3段)沉積相,從形態(tài)、范圍、分布和側(cè)向、垂向上的連通非均質(zhì)性等幾個方面來探討其儲集砂體特征,沉積類型并進一步分析其對油氣成藏的控制作用,以期對油田的進一步勘探和開發(fā)提供幫助。研究過程中,以饒陽凹陷肅寧地區(qū)古近系Es1~Ed3為主要目的層,以砂體刻畫與輸導(dǎo)體系評價為核心,綜合應(yīng)用地震資料、巖心資料、測錄井資料和地質(zhì)背景資料,系統(tǒng)建立研究區(qū)主要研究層段的等時地層格架,并通過分析相關(guān)井巖心、單井相和連井相來探尋其沉積相類型及分布規(guī)律,精細研究目的層砂體展布特征。現(xiàn)已明確了該區(qū)為流域下游曲流河沉積,具備形成巖性油氣藏的有利條件;利用層序地層學(xué)理論等精細刻畫砂體展布,進一步落實巖性圈閉的發(fā)育特征,明確油氣勘探靶區(qū);確定了“斷砂耦合,下生上儲”巖性油藏成藏新模式,明確了“縱向疊置富集、橫向復(fù)合連片”的油氣富集規(guī)律,指導(dǎo)勘探取得新發(fā)現(xiàn)。
[Abstract]:The Suning area is located in the middle of Raoyang sag, adjacent to the oil-rich depression in Hejian, and is rich in remaining oil and gas resources. It is a key target area for oil and gas preexploration. The area has a good tectonic background and excellent oil source conditions, but is affected by the remote source area and paleogeomorphology. The distribution of sedimentary facies is complex and the reservoir distribution changes rapidly. Because of the unclear understanding of the distribution of sedimentary facies plane and the spatial distribution of sand bodies, the exploration of oil and gas has been seriously restricted. Strengthening the study of sedimentary system and sand body prediction has become the key to the exploration of stratigraphic lithologic reservoirs in this area. This paper expects to study the sedimentary facies in the Paleogene of the Suning area, Raoyang Sag, from the shape, range, distribution and lateral direction. The vertical connected heterogeneity and other aspects are used to discuss the reservoir sand body characteristics, sedimentary types and further analysis of its controlling effect on oil and gas accumulation, in order to provide help for further exploration and development of oil fields. Taking the Paleogene Es1~Ed3 in Suning area of Raoyang depression as the main target layer, taking the sand body description and the evaluation of the transportation system as the core, the seismic data, core data, logging data and geological background data are used synthetically. The isochronous stratigraphic framework of the main strata in the study area is systematically established, and the types and distribution of sedimentary facies are explored by analyzing the core, single well facies and even well facies of related wells. The distribution characteristics of sand bodies in the target layer are studied in detail. It has been determined that the area is a meandering river deposit in the lower reaches of the basin, which has favorable conditions for forming lithologic reservoirs, and the distribution of sand bodies is characterized by sequence stratigraphy theory. The development characteristics of lithologic traps are further carried out, the target areas for oil and gas exploration are defined, a new model of reservoir formation in lithologic reservoirs with "sand fault coupling, lower generation and upper reservoir" is established, and the oil and gas enrichment law of "vertical superposition enrichment, horizontal composite continuous slice" is defined. Guide exploration to new discoveries.
