Hu Twelve Sand 4-8 Reservoir Fine Description And Distribution Of Remaining Oil

This article uses the the new theory and the new technology of the geology, the sedimentology, the reservoir geology, the oil reservior project and the computer science,carries on the explanation again to the complex fault block oil deposit Hu 12 structures. Under the instruction of the sedimentology and the high resolution sequence stratigraphy, synthesizing the all information of static state and dynamic state, intensively study the sandstone body scale and the continuity, the connectivity between the wells, and the parameter in the three-dimensional space distributed rule, establishes the fine reservoir geology model; Carries on sedimentary micro-facies studies, fully uses the data of well logging, the mudlogging, the thesis study the sedimentary micro-facies of the main sandstone body, analyzes in the longitudinal deposition micro change rule and the plane deposition micro characteristic; researches on influence of the reservoir fluid change to the water-oil displacement and the remaining oil distribution, establishes the reservoir forecast model, chooses the appropriate reservoir stochastic modelling method, establishes the high accuracy reservoir static state forecast model, carries on the match analysis with the production history, establishes the dynamic reservoir behavior forecast model; on the basis of former studies, the thorough research remaining oil distribution law, forecast the remaining oil distribution characteristic and rule, finally establish the remaining oil distributed model and find accurately the distribution of remaining oil distribution, on the basis of it laying out the adjusting plan to instruct the development of oil field.
