【摘要】：松遼盆地北部太平屯油田太30區(qū)塊具有良好的勘探開(kāi)發(fā)前景,扶余油層是本區(qū)新增儲(chǔ)量、進(jìn)一步開(kāi)發(fā)的重點(diǎn),但是扶余油層的砂體發(fā)育情況以及儲(chǔ)層的物性制約著本區(qū)的增儲(chǔ)上產(chǎn),所以需要進(jìn)一步認(rèn)識(shí)砂體分布規(guī)律和目的層的含油性。本文基于前人的研究成果,通過(guò)核實(shí)扶余油層地震層位,落實(shí)主要斷層,研究分析了研究區(qū)構(gòu)造、沉積特征;利用Landmark解釋系統(tǒng)中的Synthetics模塊對(duì)扶余油層的巖性層位進(jìn)行了標(biāo)定并分析了其反射波組特征;利用時(shí)間域?qū)傩苑治黾夹g(shù)、分頻解釋技術(shù)(SpecDecomp軟件)結(jié)合儲(chǔ)層沉積微相預(yù)測(cè)結(jié)果識(shí)別出河道砂體;采用Geo-office波阻抗反演和Jason中的Statmod MC電阻率反演進(jìn)行了砂巖預(yù)測(cè),識(shí)別了巖性圈閉;根據(jù)構(gòu)造圈閉幅度、圈閉面積、落實(shí)程度、圈閉形態(tài)及砂巖厚度、有效厚度的大小,儲(chǔ)層物性的好壞等要素來(lái)完成了有利區(qū)的預(yù)測(cè)。本文標(biāo)定并解釋了FⅠ上頂、FⅠ中頂、FⅠ下頂、FⅡ上頂、FⅡ下頂和底6個(gè)層位;研究區(qū)主要以淺水湖泊三角洲沉積體系為主,發(fā)育三角洲前緣和三角洲平原亞相,FⅠ砂巖組、FⅡ砂巖組上部砂體較發(fā)育,砂體呈條帶狀、串珠展布,扶余油層油氣主要集中在FⅠ組和FⅡ組上部,砂體分布應(yīng)該是油藏的主控因素;本區(qū)扶余油層主要以構(gòu)造-巖性油藏、斷層-巖性油藏為主;在綜合構(gòu)造形態(tài)、斷層特征、河道砂體展布規(guī)律以及試油試采資料的基礎(chǔ)上,對(duì)油氣聚集規(guī)律進(jìn)行了分析和認(rèn)識(shí),預(yù)測(cè)了扶余油層扶Ⅰ油層組有利含油氣區(qū)17塊,累計(jì)面積234.9km2,較有利含油氣區(qū)8塊,累計(jì)面積26.5km2,扶Ⅱ油層組有利含油氣區(qū)17塊,累計(jì)面積108.8km2,較有利含油氣區(qū)9塊,累計(jì)面積39.1km2。
[Abstract]:Tai-30 Block of Taiping Tun Oilfield in the north of Songliao Basin has a good prospect of exploration and development. Fuyu oil layer is the key point of further development and new reserves in this area. But the development of sand body in Fuyu reservoir and the physical property of reservoir restrict the increase of reservoir and production in this area, so it is necessary to further understand the distribution law of sand body and the oil content of the target layer. Based on the previous research results, by verifying the seismic horizon of Fuyu reservoir and implementing the main faults, the structural and sedimentary characteristics of the study area are studied and analyzed in this paper. The lithologic layer of Fuyu reservoir is calibrated by Synthetics module in Landmark interpretation system and the characteristics of reflected wave group are analyzed. The channel sand body is identified by using time domain attribute analysis technology and frequency division interpretation technique (SpecDecomp software) combined with reservoir sedimentary microfacies prediction results. Geo-office wave impedance inversion and Statmod MC resistivity inversion in Jason are used to predict sandstone and lithologic traps are identified. According to the factors such as the amplitude of structural trap, the area of trap, the degree of implementation, the shape of trap and the thickness of sandstone, the size of effective thickness and the quality of reservoir physical property, the prediction of favorable area is completed. In this paper, the top of F 鈪，
