【摘要】：古龍南地區(qū)位于松遼盆地中央坳陷區(qū)齊家-古龍凹陷及中央長垣的南端,表現(xiàn)為“三鼻兩洼”的構(gòu)造格局。該地區(qū)葡萄花油層在不同的構(gòu)造部位呈現(xiàn)不同的油藏類型、油水分布特征,針對油藏這種差異分布特征,本論文以葡萄花油層為主要研究對象,通過構(gòu)造單元,斷裂特征,儲層發(fā)育特征,油水分布特征等方面的研究,總結(jié)全區(qū)不同構(gòu)造單元油藏類型及油水宏觀分布規(guī)律,結(jié)合成藏主控因素綜合分析,建立油氣分區(qū)成藏模式及有利區(qū)優(yōu)選方法。本文在對研究區(qū)的構(gòu)造精細劃分以及儲層發(fā)育特征的研究基礎(chǔ)之上,對研究區(qū)189口探井進行精細油藏解剖,確定了油藏類型及其分布特征。在古龍向斜中心主要發(fā)育砂巖透鏡體油藏,邊部發(fā)育砂巖上傾尖滅、砂巖透鏡體及斷層巖性油藏;茂興向斜以PⅠ4-PⅠ6小層微幅度構(gòu)造油藏為主;新站鼻狀構(gòu)造和新肇鼻狀構(gòu)造以構(gòu)造-斷層油藏為主,由于儲層差異,油藏邊部油水關(guān)系不同;在各斜坡區(qū),受不同地層形態(tài)與斷層展布配置關(guān)系及儲層發(fā)育特征,分別發(fā)育斷層巖性油藏、構(gòu)造巖性油藏及砂巖上傾尖滅油藏。在古龍南地區(qū)葡萄花油層源巖評價、輸導(dǎo)通道、砂體連通性等因素綜合分析基礎(chǔ)上,對研究區(qū)不同構(gòu)造區(qū)油氣成藏模式進行了總結(jié):(1)古龍和茂興向斜區(qū),優(yōu)質(zhì)儲層控制的巖性油藏成藏模式;(2)新站、新肇和敖南鼻狀構(gòu)造區(qū),為斷層分割鼻狀構(gòu)造隆起的構(gòu)造油藏成藏模式;(3)新肇斜坡和新站斜坡,斷層遮擋斷層-巖性油藏和反轉(zhuǎn)背形構(gòu)造-巖性油藏成藏模式;(4)英臺斜坡,巖性上傾尖滅油藏成藏模式。
[Abstract]:Gulongnan area is located in Qijia-Gulong depression of Songliao Basin and the southern end of central Placanticline, which is characterized by "Sanbei and Liangwa" tectonic pattern. In this area, there are different reservoir types and oil and water distribution characteristics in different structural positions in this area. In view of this kind of differential distribution characteristics of reservoirs, this paper takes the Putaohua reservoir as the main research object, through structural units, fault characteristics, The characteristics of reservoir development and oil-water distribution are studied. The reservoir types of different structural units and the macroscopic distribution of oil and water in the whole area are summarized. Combined with the comprehensive analysis of the main factors of reservoir formation, the reservoir forming model and the favorable area selection method are established. Based on the study of the fine division of structure and the characteristics of reservoir development in the study area, the fine reservoir anatomy of 189 exploration wells in the study area was carried out, and the reservoir types and their distribution characteristics were determined. In the center of Gulong syncline, sandstone-lens reservoir is mainly developed, and the edge part is developed by sandstone updip pinning, sandstone lens body and fault lithologic reservoir, and Maoxing syncline is mainly composed of P 鈪，
