【摘要】：新立地区位于松辽盆地南部中央坳陷区扶新隆起带西缘新立构造上。根据目前试油资料,本区主要产层为黑帝庙油层及扶杨油层,本次主要针对黑帝庙油层(嫩三、嫩四段)开展工作。新立地区周边的三肇及长岭两个生油凹陷,是黑帝庙油层油气的主要来源,油源丰富,生成的油气沿该区东西向的断裂运移至目的层,同时与新立长期发育的古隆起相配置,十分有利于油气的聚集。论文研究主要包括构造解释及储层预测两部分。在构造解释方面,基于精细的井震标定,明确目的层反射形态,开展密井网层位解释。另外在断层解释方面,采用平面、剖面相对应的方法,平面指导剖面的原则,以及结合断层体解释的空间结构来准确识别断层。最终落实重点反射层位的构造形态,断裂特征。并针对重点构造圈闭开展有效性评价。储层预测方面,根据砂岩在地震剖面上的反射特征,砂岩表现为中强振幅,中低频率,因此振幅和频率属性在该地区对平面沉积相刻画效果较好。通过开展叠前、叠后地震属性对比,有效预测河道砂体发育范围。通过开展分频泥质含量反演,反演预测结果与已知井的泥质含量曲线吻合较好,因此该反演结果可以用来预测目的层段无井区的岩性。进一步结合单砂体雕刻技术,有效指导井位部署。通过本次研究,对新立地区的构造形态及砂体预测形成了一套合理的研究路线,并取得了很好的应用效果,对本区黑帝庙油层勘探具有指导意义。
[Abstract]:The Xinli area is located on the western margin of the Fuxin uplift belt in the central depression of the southern Songliao Basin. According to the current oil testing data, the main production layers in this area are the Heidimiao oil layer and Fuyang oil layer, this work is mainly aimed at the Heidimiao oil layer (Nen 3, Nen 4 member). The Sanzhao and Changling oil source sag around Xinli area is the main source of oil and gas in Heidimiao oil reservoir, which is rich in oil and gas. The generated oil and gas are migrated along the east-west fault to the destination layer, and are configured with the newly developed paleouplift facies. It is very favorable to the accumulation of oil and gas. This paper mainly includes two parts: structural interpretation and reservoir prediction. In terms of structural interpretation, based on fine well seismic calibration, the reflection form of target layer is defined, and the interpretation of dense well pattern is carried out. In addition, in fault interpretation, the corresponding method of plane and section, the principle of plane guiding section and the spatial structure of fault body interpretation are used to identify fault accurately. Finally, the structural form and fault characteristics of the key reflection horizon are carried out. The effectiveness evaluation of key structural traps is also carried out. In reservoir prediction, according to the reflection characteristics of sandstone in seismic profile, sandstone shows moderate amplitude and low frequency, so amplitude and frequency attributes are better in describing planar sedimentary facies in this area. By comparing prestack and poststack seismic attributes, the development range of channel sand body is predicted effectively. The inversion results are in good agreement with the mud content curves of known wells, so the inversion results can be used to predict the lithology of well free areas in the target interval. Further combined with single sand body carving technology to effectively guide the well location deployment. Through this study, a set of reasonable research route has been formed for the prediction of structural morphology and sand body in Xinli area, and good application effect has been obtained, which is of guiding significance to the exploration of Heidimiao reservoir in this area.
