Research And Application Of Hydrocarbon Reservoir Sweet Spot Prediction Method

According to the actual needs of the project research and mainly based on the actual data of well YB1 in Xinjiang District of Junggar basin,this paper carry out the study area Baikouquan formation of high quality reservoir(dessert)method research and application of earthquake prediction.On the basis of analyzing the actual data on the basis of the study area of Baikouquan oil and gas center evaluation criteria and the main controlling factors are studied,summarized and the dessert(reservoir)the main control factors are: favorable sedimentary facies;fractures;lithology and physical property advantageous area.According to the main controlling factors of sweet food,the suitable seismic prediction method is selected,and the seismic identification and prediction of the main controlling factors are carried out according to the geological and drilling data.On the basis of the seismic identification and prediction of these main factors,a series of seismic prediction methods and the working flow of the study area are presented.These methods and processes are applied to the actual reservoir prediction in the study area,and the results are satisfactory.This paper also analyzes the characteristics of the dessert reservoir seismic response,mainly through forward simulation,and on the sand with different sedimentary facies in the actual data body stacked under such circumstances,the variation characteristics of seismic response were studied and summarized some seismic attributes analysis of sedimentary facies the theoretical basis and identification of sandbody superimposition method of identification,which laid the foundation for the accurate identification of the reservoir in this area for dessert.This study explains the fault system in YB2 area,YB2 YB1,has been implemented two fault block traps;research study areas for crack faults associated fractures,fractures are mainly in the vicinity of large fault zone,a total of 2 pieces of YB2 well area implementation of fractured zone;comprehensive prediction of high-quality reservoir each master the factors that the target layer in the study area a total of 2 pieces of high quality reservoir development zone.The favorable reservoirs are as follows: YB2 well area,YB1 well area above research results provide favorable support for the exploration and deployment of the study area.This study established the reservoir seismic prediction technique for dessert and work flow has an important reference value for the future research of dessert and similar regions prediction,and can be used in similar application area.
