【摘要】：庙三地区所处的松辽盆地南部地区是油气富集区和勘探开发的有利区,多年的勘探与开发实践揭示出目前扶杨油层存在的下列地质问题有待深入研究,如:地层划分与对比不统一、优质储集相带的沉积微相类型认识不清、控制产能高低的主控因素尚不明确等,虽然在1999年以来相继开展过一些相关研究,但由于多是勘探阶段宏观研究。目前的地质认识已明显不能满足油田进一步评价及开发的需要。因此,急需运用层序地层学原理展开全区地层统一划分与对比、建立等时地层格架等工作,以满足提高地质认识、确定有利的沉积相带分布、开展评价部署、提高产能等需求。首先在新民、木头油田对比的基础上,以庙7-38井、庙11-38井、庙15井为标准井,按单期河流层序将扶杨油层16小层划分为37个单层;按照岩性、古生物化石、单砂体形态、测井曲线4大类指标识别出2相3亚相17微相12能量单元,从标准井出发,对全区62口井37时间单元进行整体、统一、精细的对比,为之后的精细地质研究奠定高分辨率地层基础。接下来对全区扶杨油层共37个时间单元平面沉积微相进行精细刻画并统计各时间单元的孔隙度、渗透率分布及分组频率,达到对每个时间单元的砂体展布特征、物性特征、平面非均质性特征都有清楚的认识。运用源控含油系统理论及其综合分析技术,认为研究区油气呈多向多路运聚模式,成藏模式为上生-下运-侧储式。对37个时间单元分别进行单一圈闭分析,圈出含有储量的圈闭65个,最终预测出4类6处有利区。
[Abstract]:The southern area of Songliao Basin in Miao3 area is a favorable area for oil and gas accumulation and exploration and development. The exploration and development practice for many years reveals that the following geological problems existing in Fuyang oil formation need to be further studied. For example, the stratigraphic division and correlation are not unified, the types of sedimentary microfacies in high-quality reservoir zones are not clear, and the main controlling factors to control productivity are not clear, although some related studies have been carried out since 1999. However, because of the exploration stage of macro-research. The present geological knowledge obviously can not meet the needs of further evaluation and development of oil fields. Therefore, it is urgent to apply the principle of sequence stratigraphy to the unified division and correlation of stratigraphy and the establishment of isochronous stratigraphic framework in order to meet the needs of improving geological understanding, determining favorable distribution of sedimentary facies, developing evaluation and deployment, and increasing productivity. First of all, on the basis of the correlation between Xinmin and Mu oil fields, taking Miao 7-38 well, Miao 11-38 well and Miao 15 well as standard wells, the 16 layers of Fuyang oil reservoir were divided into 37 single layers according to single stage river sequence; according to lithology, paleontological fossils, single sand body morphology, Four kinds of logging curve indexes identify 2 phase 3 subfacies 17 microfacies 12 energy units. Starting from the standard well, the 37 time units of 62 wells in the whole area are compared in a unified and fine way. It lays a high resolution stratigraphic foundation for the later fine geological research. Then, the planar sedimentary microfacies of 37 time units in Fuyang oil formation in the whole area are carefully depicted and the porosity, permeability distribution and grouping frequency of each time unit are counted, so that the distribution characteristics of sand body and physical properties of each time unit can be achieved. There is a clear understanding of the characteristics of plane heterogeneity. Based on the theory of source-controlled oil bearing system and its comprehensive analysis technique, it is considered that the oil and gas in the study area are multi-path migration and accumulation mode, and the reservoir formation model is upper-down-traverse-lateral storage model. Through single trap analysis of 37 time units, 65 traps containing reserves are formed, and 4 types and 6 favorable regions are predicted.
