Complicated fault-block reservoir have being particular complex structure and reservoir and fluid feature. This dissertation combination geology, log, boring with sampling, testing for oil, development performance datum atc. Take development geology, log , sediment, geology model, reservoir engineering, reservoir numerical analogue, geophysics direction as to guide. We will separate into 8 special topic launch thorough study in region of interest. Including with the fine correlation of strata, precipitation facie research, fine structure elucidation, reservoir parameter interpretation model, Dynamic flow unit divide, build the reservoir geologic model, reservoir engineering , reservoir numerical analogue and oil remaining comprehensive evaluation approach. Pass by used the new reservoir characterizations, consist of the cohere analysis method , FZI restrict log interpretation method, neural network model distinguish sedimentary facies atc. Carefully divide unit to pursue the layer gradually fine analysis. Realization oil remaining distribute synthesize forecast. At the same time put forward oil field development adjusts and deployment suggestion.Through the research, the following results are achieved:1. Study the area adopted the technique of the Coherence to fine interpretation fault, through interpretation diagram accuracy be obviously raised. This region structure cognition have major changed. By this fine structure interpretation, the new interpretation structure from original 11 faults change into now 14 faults. The central faults have major changed.2. By use of the neural network model distinguish sedimentary facies, compare with the core sedimentary facies, electrofacies identify accuracy content to the demand of research. Through divide sedimentary facies, we have point out ES3Xâ…¡-1 sublayer,ES3Xâ… -1 sublayer, ES3SH-1 are main distribute to the sublayer plant braided channel and under water channel facies, this facies are superlative reservoir in study the area.3. Aim at to the reservoir shale content high, rock differentiate is worse, rock and electric nature relationship ambiguous characteristics in this region, we have propose a new interpretation physical property parameter clue by the divide the different flow units interpretation. This clue versus the classic method will best raised interpretation accuracy, The method will provide a substantial base for the best create fine geologic model.4. By reflection capillary pressure and phase permeability curve characteristic parameters, we obtain divide Dynamic flow unit parameter index, according to the the actual situation optimization divide Dynamic flow unit parameter index in this area. Respectively established the fan delta and turbidite fan Dynamic flow unit models, These provide a substantial base for oil remaining evaluate.This dissertation put forward a new means for fit the remaining oil prediction in the development Medium-High period. Through the Dynamic flow unit and reservoir simulation method combine organically. This text investigate a new method of Comprehensive estimate remaining oil in the development Medium-High period reservoir. These methods will have the important sense to the oil remaining mapped out.
