【摘要】：本文通過對鐵匠爐地區(qū)大量的測井資料、錄井資料、鉆井資料等基礎(chǔ)資料進行收集以及對國內(nèi)外文獻資料的分析,對鐵匠爐地區(qū)的儲層特征進行了深入細致的研究,識別出鐵匠爐地區(qū)的優(yōu)勢儲層,并對其油氣藏的成因及其對儲層的影響進行了細致的研究,對鐵匠爐地區(qū)的儲層進行了評價。主要取得了以下結(jié)論和認識:(1)通過對研究區(qū)沙一段地層進行精細對比與劃分,將沙一段劃分為沙一上+中和沙一下兩個亞段,又將沙一下亞段精確劃分為砂巖組級別,即S1下I1、S1下I2、S1下I3,并在平面上展布各個油層組的地層分布特征。(2)通過對鐵匠爐地區(qū)的沉積相進行分析研究,由于鐵匠爐地區(qū)在沙一時期接受由北東方向中央凸起的物源沉積,使得多個砂體一起在平面上疊加成片在斜坡帶超覆沉積,形成扇三角洲沉積砂體,主要發(fā)育扇三角洲前緣亞相,可進一步將扇三角洲前緣亞相劃分為河道等4種沉積微相。(3)對已知油氣藏進行精細解剖,梳理油氣成藏主控因素發(fā)現(xiàn),構(gòu)造背景控制油藏類型,疏導(dǎo)體系控制分布格局;沉積背景控制油氣富集,巖性、物性影響油氣成藏;油源條件必不可少,保存條件是成藏關(guān)鍵。通過以上分析我們有以下幾點認識:(1)斷層和不整合面對油藏的分布起決定性作用,加強對沙一段內(nèi)部39條斷層兩側(cè)油源與儲層的對接關(guān)系研究,以尋找更多的有利區(qū)帶和目標;(2)通過對南北斜坡帶油氣成藏特點的仔細對比研究,我們可以總結(jié)認為,北段斜坡帶主要為“古地貌控砂,物性控油”,南段斜坡帶主要為“相帶控砂,斷層控油”;(3)加強鐵匠爐地區(qū)沙一到沙三地層研究,雖然目前沙三砂巖油藏發(fā)現(xiàn)較少,而從成藏方面來說,應(yīng)該具備最有利的成藏要素。
[Abstract]:Through collecting a lot of logging data, drilling data and other basic data in the blacksmith furnace area, as well as analyzing the domestic and foreign literature data, this paper makes a thorough and detailed study on the reservoir characteristics in the blacksmith furnace area. The dominant reservoir in the blacksmith furnace area is identified, the origin of the reservoir and its influence on the reservoir are studied in detail, and the reservoir in the blacksmith furnace area is evaluated. The following conclusions and understandings are obtained: (1) by fine correlation and division of the strata of the first member of the sand formation in the study area, the first member of the formation is divided into two subsections, namely, the upper part of the sand and the lower part of the sand, and the submember of the lower part of the sand is accurately divided into sandstones. That is, I _ (1) I _ (1) I _ (1) I _ (2) S _ (1) S _ (1), I _ (2) I _ (3), and distributes the stratigraphic distribution characteristics of each oil formation on the plane. (2) by analyzing the sedimentary facies in the blacksmith furnace area, because the blacksmith furnace area accepted the protruding material deposits from the north to the east in the first stage of the sand, As a result, many sand bodies are superimposed on the plane and superimposed on the slope zone to form fan delta sedimentary sandbodies, which mainly develop fan delta front subfacies. The fan delta front subfacies can be further divided into four sedimentary microfacies, such as river channel, etc.) the known oil and gas reservoirs can be carefully dissected, and the main controlling factors of oil and gas accumulation can be found. The tectonic background controls the reservoir type and the dredge system controls the distribution pattern. Sedimentary background controls oil and gas accumulation, lithology and physical property affect oil and gas accumulation, and oil source condition is indispensable, and preservation condition is the key to reservoir formation. Through the above analysis, we know that the fault and unconformity play a decisive role in the distribution of reservoirs, and strengthen the research on the docking relationship between oil sources and reservoirs on both sides of 39 faults in Shayi formation. In order to find more favorable zones and targets, we can conclude that the northern slope zone is mainly "paleogeomorphic sand control, physical oil control" through careful comparative study of the characteristics of oil and gas accumulation in the north and south slope zones. The slope belt in the south section is mainly composed of "facies belt controlling sand, fault controlling oil" and so on) to strengthen the study of sand 1 to sand 3 stratigraphy in blacksmith furnace area. Although there are few sandstone reservoirs in sand three at present, there should be the most favorable reservoir forming elements in terms of reservoir formation.
