Remaining Oil Distribution

Inefficient reserves in fault block belongs to low permeability thin interbed, thus water flooding development process has exposed many contradictions which are serious heterogeneity, large difference of suction of interlayer. Entering the water injection development, the injected water which rapidly advance along the high permeability channel causes water channeling and water flooding, which intenses development contradictions between layers. The reservoir numerical simulation technology on computer can reappear the movement of water and gas in the underground reservoir development process and describes the underground remaining oil distribution of inefficient reserves in complex fault block, which summarizes the remaining oil distribution rule of the water flooding development for complex fault block of inefficient reserves and provides basis for the establishment of oil field development adjustment scheme.

Remaining Oil Distribution

With the deepening exploitation percent, underground water relations have become more complex and tap the oil field at stable yields is more and more difficult, thus make us develop in depth study about the remaining oil distribution become critical. The proved geological reserve is high and physical property is better in 402 block’s group CIII of Tazhong 4 Oilfield. Combined with current mining situation in TZ402CIII oil group and in order to proven the distribution of the remaining oil, we used common reservoir engineering methods, neutron lifetime logging data analysis over the years and sweep efficiency analysis from sealed coring wells to study in-depth current remaining oil distribution range in TZ402CIII oil group, which provide an important basis to further improve development effect, dig remaining oil, as well as secondary development and adjust tap the potential in TZ402CIII oil group.

Remaining Oil Distribution

Figuring out the rule of remaining oil distribution after polymer flooding is the basis for continuing study on development policy after polymer flooding in Daqing Oil Field. Based on the basic principles of percolation mechanics, percolation mechanics of polymer flooding reservoirs under fixed injection pressure and injection rate was studied, the mechanism of remaining oil changes after polymer flooding was investigated; According to the numerical simulation results, the rule of remaining oil distribution in Daqing oilfield has been given out. This will be theoretical and practical guidance for enhancing oil recovery after polymer flooding.

Remaining Oil Distribution

The micro-structure of sand body is relative to waterflooding rule and remaining oil distribution closely. Based on the division of single sand body, the type and the feature of the micro-structure of sand body of X formation in X area are researched. Five types of micro-structure are concluded：structural height，fault height, neighbouring fault, the area controlled by parallel fault, clinoform.And the affection of different type of micro-structure on remaining oil distribution is studied, which can indicate tapping the latent and the development of remaining oil.

Water Cut

Sanan oilfield has entered late stage of high water cut development. It urgently needs accurate prediction of remaining oil distribution. But previous studies on 3D structure were far could not meet the requirements of fine reservoir description. This paper applied RMS, a piece of excellent geological modeling software establishing the 3D fine structural model of typical block in Sanan oilfield on the bases of 3D fine seismic structural interpretation data. It included the 28 faults’ model, 11 horizons’ model and the structural model. And then measured and analyzed the faults elements data. Based on abundant geologic data, well data and seismic data of the block, this structural model reproduced the fine seismic interpretation results accurately. It was really fine enough to meet the requirements of the fine reservoir description. This research solved the problem that traditional modeling techniques could not handle complex cutting relationship of faults’ model. It laid a solid foundation for reservoir numerical simulation and remaining oil distribution prediction.
