【摘要】：作為我國中、新生代陸相盆地重要油氣儲集層系類型之一,遼河奈曼油田為加快油氣勘探步伐,進(jìn)一步搞好產(chǎn)能建設(shè),需要進(jìn)行精細(xì)油藏描述及剩余油分布研究。本文將地質(zhì)、地震、測井、油藏工程、數(shù)值模擬等統(tǒng)一于油藏精細(xì)描述之中,結(jié)合新增的油藏靜、動態(tài)資料,確定油層的劃分標(biāo)準(zhǔn),并對地層對比與劃分到單層。對儲層構(gòu)造形態(tài)等進(jìn)行研究,描述微構(gòu)造剩余油富集的有利圈閉及微構(gòu)造與剩余油的關(guān)系。分開發(fā)單元、主力小層進(jìn)行微構(gòu)造研究,建立分油層組、砂巖組的宏觀構(gòu)造模型和分開發(fā)單元的微構(gòu)造模型。應(yīng)用資料進(jìn)行沉積微相研究,重點(diǎn)研究不同微相對開發(fā)的影響。開展儲層的成巖作用、物性、非均質(zhì)性、注水后變化特征研究;開展測井儲層評價,建立儲層地質(zhì)模型。通過對流體的性質(zhì)等在開發(fā)過程中的變化研究,建立油藏流體模型,分層編制不同流體平面分布圖。最后,在沉積模型、構(gòu)造模型、油藏流體模型及儲層地質(zhì)模型的基礎(chǔ)上,建立九上段油藏三維綜合地質(zhì)模型,進(jìn)行油藏地質(zhì)綜合評價。進(jìn)行九上段油藏儲量復(fù)算。剩余油分布富集規(guī)律研究。
[Abstract]:As one of the important types of oil and gas reservoirs in Mesozoic and Cenozoic continental basins, Liaohe Neiman Oilfield needs to study the fine reservoir description and the distribution of remaining oil in order to speed up oil and gas exploration and further improve productivity construction. In this paper, geological, seismic, logging, reservoir engineering and numerical simulation are unified in the fine description of the reservoir. Combined with the newly added static and dynamic data of the reservoir, the criteria for the division of the reservoir are determined, and the stratigraphic correlation and division to a single layer are made. The structure morphology of reservoir is studied to describe the favorable trap of microstructural residual oil enrichment and the relationship between microstructure and remaining oil. The microstructural model of the oil reservoir, sandstone formation and the sub-development unit is established by studying the microstructures of the main layers and the development units. The sedimentary microfacies were studied by using the data, and the effects of different microstructures on the development were studied. The reservoir diagenesis, physical property, heterogeneity, characteristics of changes after water injection are studied, well logging reservoir evaluation is carried out and reservoir geological model is established. Through the study of the change of fluid properties in the development process, the reservoir fluid model is established, and different fluid plane distribution maps are compiled by stratification. Finally, on the basis of sedimentary model, structural model, reservoir fluid model and reservoir geological model, a three dimensional comprehensive geological model of the upper segment of Jiujiu reservoir is established for comprehensive evaluation of reservoir geology. The reservoir reserves of the upper segment of Jiu are recalculated. Study on the Law of remaining Oil Distribution and enrichment.
