【摘要】：廟三地區(qū)所處的松遼盆地南部地區(qū)是油氣富集區(qū)和勘探開發(fā)的有利區(qū),多年的勘探與開發(fā)實踐揭示出目前扶楊油層存在的下列地質(zhì)問題有待深入研究,如:地層劃分與對比不統(tǒng)一、優(yōu)質(zhì)儲集相帶的沉積微相類型認識不清、控制產(chǎn)能高低的主控因素尚不明確等,雖然在1999年以來相繼開展過一些相關(guān)研究,但由于多是勘探階段宏觀研究。目前的地質(zhì)認識已明顯不能滿足油田進一步評價及開發(fā)的需要。因此,急需運用層序地層學(xué)原理展開全區(qū)地層統(tǒng)一劃分與對比、建立等時地層格架等工作,以滿足提高地質(zhì)認識、確定有利的沉積相帶分布、開展評價部署、提高產(chǎn)能等需求。首先在新民、木頭油田對比的基礎(chǔ)上,以廟7-38井、廟11-38井、廟15井為標準井,按單期河流層序?qū)⒎鰲钣蛯?6小層劃分為37個單層;按照巖性、古生物化石、單砂體形態(tài)、測井曲線4大類指標識別出2相3亞相17微相12能量單元,從標準井出發(fā),對全區(qū)62口井37時間單元進行整體、統(tǒng)一、精細的對比,為之后的精細地質(zhì)研究奠定高分辨率地層基礎(chǔ)。接下來對全區(qū)扶楊油層共37個時間單元平面沉積微相進行精細刻畫并統(tǒng)計各時間單元的孔隙度、滲透率分布及分組頻率,達到對每個時間單元的砂體展布特征、物性特征、平面非均質(zhì)性特征都有清楚的認識。運用源控含油系統(tǒng)理論及其綜合分析技術(shù),認為研究區(qū)油氣呈多向多路運聚模式,成藏模式為上生-下運-側(cè)儲式。對37個時間單元分別進行單一圈閉分析,圈出含有儲量的圈閉65個,最終預(yù)測出4類6處有利區(qū)。
[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.
