Study On Fine Reservoir And Adjustment And Deployment Of Yu102-Yu33 Well Area In YuLou Oilfield

Because the study area belongs to the complex fault block reservoir,with the continuous development of the reservoir,the developing effect is deteriorating,so it is necessary to carry out the detailed description of the reservoir and analyze the remaining oil distribution according to the current development situation.On the basis of the above research,the study area is adjusted to improve the developed effect.The characteristics of 3D seismic data interpretation method is used to recognize YuLou oilfield tectonic,the characteristics of sedimentary and reservoir.The method of material balance,dynamic analysis and numerical simulation is used to predict the distribution of residual oil and longitudinal,and the remaining oil reserves are calculated.,the distribution of the remaining reservoirs is obtained by analyzing the main controlling factors of the remaining oil distribution,and on the basis of analysis,the current layer,well pattern,the rationality of injection and pressure system and the effect of a variety of increasing developed measures are analyzed and advice for adjustment is proposed.Through the adjustment and deployment,the basis for storage is provided for the district and recovery,and the remaining oil potential is fully taped.through.the following conclusions are get by the above research.The distribution of sand bodies in the well area is controlled by the sedimentary facies belt,and the main body of the main channel zone is large.The physical properties are good and the reservoir is developed.Due to the narrowness of the river channel and the rapid change of the plane,the sandstone group and the small sandstone are vertical and horizontal heterogeneity,and the oil-water relationship is complicated.Based on the analysis of the relationship between the distribution of oil layers and the production dynamics,the oil well production in the study area is very different.This is mainly related to the distribution of oil layer,and the production condition of reservoir at the lower section of S1 is better than S3.But constrained by the low degree of connectivity,water recharge only from the perfect well pattern can not be achieved.The flexible and diverse way is taken to improve the developing effect.
