【摘要】：松遼盆地是油氣資源豐富的陸相含油氣盆地,隨著油氣田勘探開發(fā)的深化,勘探開發(fā)對象的復雜程度逐年增高,油田含水上升較快,開采難度不斷增加。古龍南地區(qū)作為松遼盆地產油的重要區(qū)塊之一,為了更好的勘探開發(fā)該區(qū)塊,結合前人研究成果,利用古龍南地區(qū)葡萄花油層詳實的巖心、地震、測井及鉆井等資料,對古龍南地區(qū)構造特征、沉積演化、物源控制及成藏模式進行了精細研究,總結了該區(qū)的油氣富集規(guī)律,確定了有利油氣富集區(qū)。經過研究分析表明,研究區(qū)的凹凸構造格局為明水組末期形成,斷層主要變形期為青山口組至嫩江組沉積期,首次提出茂興三維區(qū)發(fā)育有油源多邊形斷層,為油氣垂向提供充足的垂向輸導通道;研究區(qū)葡萄花油層主要受北部和西北部物源控制,主體物源為北部物源,主要砂體為水下分流河道、河口壩和席狀砂,砂體平面上厚度分布不均勻,呈現西北厚,東南薄的趨勢,P下和P上砂體薄、分布范圍小,P中砂體厚、分布范圍廣;研究區(qū)油水垂向分布存在5種類型,即全井純油型、上油下水型、油水同層型、全井純水型、雜亂型。油主要分布在PⅠ1-PⅠ6小層;研究區(qū)共存在7種油氣藏類型,主要發(fā)育有構造油藏、斷層巖性油藏、構造巖性油藏、砂巖透鏡體油藏及砂巖上傾尖滅油藏,通過油藏解剖、主控因素分析,確定新站西、肇西、肇南斜坡區(qū)主控因素為斷砂匹配,敖南鼻周邊斜坡區(qū),儲集砂體富集程度為成藏主要控制因素。從構造、沉積、油藏等多方面考慮,對目前開發(fā)的空白區(qū)進行了有利區(qū)預測,提交建議井位4口,為古龍南地區(qū)葡萄花油層下一步增儲上產指明了方向。
[Abstract]:Songliao Basin is a continental oil-bearing basin rich in oil and gas resources. With the deepening of exploration and development of oil and gas fields, the complexity of exploration and development objects increases year by year, the water cut of oil field rises rapidly, and the difficulty of exploitation increases continuously. As one of the important oil production blocks in Songliao Basin, Gulongnan area, in order to better explore and develop the block, combined with previous research results, using the detailed core, earthquake, logging and drilling data of Gulongnan area, The structural characteristics, sedimentary evolution, provenance control and reservoir forming model in Gulongnan area are studied in detail, and the oil and gas enrichment laws in this area are summarized, and favorable oil-gas accumulation areas are determined. The research and analysis show that the concave and convex tectonic pattern of the study area is formed at the end of Mingshui formation, and the main deformation period of the fault is the sedimentary period from Qingshankou formation to Nenjiang formation. It is the first time that the oil source polygonal fault developed in the three dimensional area of Maoxing. The study area is mainly controlled by the north and northwest provenances, the main provenance is the northern provenance, the main sand body is the underwater distributary channel, the estuarine dam and the sheet sand. The thickness distribution of sand body on the plane is not uniform, showing the trend of northwest thickness and southeast thickness. The sand body is thin under P and on P, and the distribution range is small. There are five types of vertical distribution of oil and water in the study area, that is, the oil and water vertical distribution of the whole well is pure oil type. Oil-on-water type, oil-water same-layer type, all-well pure water type, messy type. The oil is mainly distributed in P 鈪，
