【摘要】：松辽盆地北部太平屯油田太30区块具有良好的勘探开发前景,扶余油层是本区新增储量、进一步开发的重点,但是扶余油层的砂体发育情况以及储层的物性制约着本区的增储上产,所以需要进一步认识砂体分布规律和目的层的含油性。本文基于前人的研究成果,通过核实扶余油层地震层位,落实主要断层,研究分析了研究区构造、沉积特征;利用Landmark解释系统中的Synthetics模块对扶余油层的岩性层位进行了标定并分析了其反射波组特征;利用时间域属性分析技术、分频解释技术(SpecDecomp软件)结合储层沉积微相预测结果识别出河道砂体;采用Geo-office波阻抗反演和Jason中的Statmod MC电阻率反演进行了砂岩预测,识别了岩性圈闭;根据构造圈闭幅度、圈闭面积、落实程度、圈闭形态及砂岩厚度、有效厚度的大小,储层物性的好坏等要素来完成了有利区的预测。本文标定并解释了FⅠ上顶、FⅠ中顶、FⅠ下顶、FⅡ上顶、FⅡ下顶和底6个层位;研究区主要以浅水湖泊三角洲沉积体系为主,发育三角洲前缘和三角洲平原亚相,FⅠ砂岩组、FⅡ砂岩组上部砂体较发育,砂体呈条带状、串珠展布,扶余油层油气主要集中在FⅠ组和FⅡ组上部,砂体分布应该是油藏的主控因素;本区扶余油层主要以构造-岩性油藏、断层-岩性油藏为主;在综合构造形态、断层特征、河道砂体展布规律以及试油试采资料的基础上,对油气聚集规律进行了分析和认识,预测了扶余油层扶Ⅰ油层组有利含油气区17块,累计面积234.9km2,较有利含油气区8块,累计面积26.5km2,扶Ⅱ油层组有利含油气区17块,累计面积108.8km2,较有利含油气区9块,累计面积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，
