【摘要】：大慶葡南油田黑帝廟油層的試油工作于1967年開始,但到目前為止,黑帝廟淺層氣仍處于評價階段,尚未進行大規(guī)模開發(fā)。葡南葡194-16井區(qū)位于葡萄花油田南部葡南鼻狀構造帶,面積約12.6km2,是目前黑帝廟層重要的油氣增儲潛力區(qū)。自2007年起,在葡194-16井區(qū)開展了多次試氣工作,油氣顯示良好,針對葡南油田田田黑帝廟油層砂體分布規(guī)律及油水分布特征研究作為油田開發(fā)的地質依據(jù),成為推進勘探開發(fā)工作的核心和重點。本文以層序地層學、沉積巖石學、石油地質學等油氣田開發(fā)地質相關理論作為基礎,以大慶葡萄油田黑帝廟油層為研究目標,結合研究區(qū)實際勘探開發(fā)數(shù)據(jù),利用三維高分辨地震、儲層反演預測、AVO烴類檢測、套后中子資料分析等技術手段,開展研究區(qū)的構造特征、儲層特征以及油水分布規(guī)律開展地質規(guī)律再認識研究。結果表明:葡194-16井區(qū)位于葡萄花構造向西南延伸部分的葡西鼻狀構造帶西側葡-1號構造內,為典型的斷鼻型構造圈閉,是葡西鼻狀構造被19號斷層切割形成的,且斷裂深度較大,在三層構造圖上均有明顯發(fā)育。根據(jù)砂體等值圖,HⅠ組油層組砂巖發(fā)育明顯優(yōu)于HⅡ組,其中HⅠ 2、HⅠ 3、HⅠ 5最為發(fā)育,其次是HⅠ 4、H Ⅰ6, HⅡ組除HⅡ1有不足2m的砂體發(fā)育外,其余分層組砂體均不發(fā)育;葡194-16井區(qū)砂體平面和縱向非均質性突出,縱向薄互層且層數(shù)多,平面相變快。單井縱向砂體總數(shù)平均23.4m,平均單層鉆遇厚度為2.7m,且有21.5%的單井無5m以上的砂體發(fā)育;平面表現(xiàn)為砂體孤立、無連通,砂體厚度變化快。葡194-16井區(qū)為構造—巖性油氣藏,含油氣富集程度取決于砂體與局部構造的配置。圈閉內為油氣層,砂體規(guī)模大,油氣水可以在局部構造內分異;圈閉外為水層,砂體規(guī)模小,含油氣連續(xù)性差。通過構造精細解剖、儲層精細描述、油水精細分析等一系列工作的開展,在研究區(qū)的構造特征、儲層刻畫以及剩余油分布規(guī)律清晰認識的基礎上,落實油氣水關系,明確油藏類型,結合區(qū)域AVO烴類檢測資料、套后中子資料、試油井、生產井等資料,將研究井區(qū)油氣潛力分布分為三個級別,實現(xiàn)油氣富集有利區(qū)預測與評價,為葡194-16井區(qū)黑帝廟層的進一步布井開發(fā)提供有力的理論依據(jù)和技術支持。
[Abstract]:The test work of Heidimiao reservoir in Punan oilfield of Daqing began in 1967, but up to now, the shallow gas of Heidimiao oil field is still in the evaluation stage and has not been developed on a large scale. Well area 194-16 is located in the southern Punan nose structural zone of Putaohua Oilfield with an area of about 12.6km2. It is an important oil and gas accumulation potential area in Heidimiao formation at present. Since 2007, many gas tests have been carried out in Pu194-16 well area, and the oil and gas show well. According to the distribution law of sand body and oil-water distribution characteristics of Hedimiao oil reservoir in Punan Oilfield, the research is used as the geological basis for oilfield development. To become the core and focus of the exploration and development work. Based on the related theories of sequence stratigraphy, sedimentary petrology, petroleum geology and other oil and gas fields, this paper takes the Heidimiao reservoir of Daqing Grape Oilfield as the research object, and combines the actual exploration and development data of the study area. By means of 3-D high-resolution earthquake, reservoir inversion prediction, AVO hydrocarbon detection, post-neutron data analysis and other technical means, the structural characteristics, reservoir characteristics and oil-water distribution law of the study area are studied again. The results show that the Pu-194-16 well area is located in the west side of the Puxi nasal structural belt extending southwest of the Puxi nose structure belt. It is a typical fault nose type structural trap formed by the cut of the Puxi nose structure by fault No. 19. The fault depth is very deep, and it is obviously developed on the three-layer structural map. According to the sand body equivalent diagram, the sandstone development of H 鈪，
