Characterization Of Single-stage Faults And Optimization Of Favorable Area In Xing 10 Block Of Daqing Placanticline

In the past,the study of remaining oil in the fault side is analyzed from the perspective of reservoir heterogeneity,micro-amplitude structur,the status of development and utilization,and the control of the fault geometry and the fault structure to the remaining oil distribution is neglected.therefore,by using the combination of well-shock and seisimic and the structural interpretation,the fine interpretation of the fault in the study area and the fine identification of the nearby microstructure are carried out to improve the accuracy of the fault characterization.it is of great significance to the work of tapping the remaining oil.Firstly,by analyzying the regional tectonic characteristics and geometric kinematics characteristics of the Xing 10 block,the fracture activity was determined in detail and the evolution history of the fracture was systematically analyzed.Secondly,it is used to check the fault points and the characteristics of the breakpoints' distribution and regular pattern.It is found that there is a contradiction on a single fault with more than one breakpoint.With the doubt we introduced the theory of fractured segmentation growth.Based on the research on the fracture research at home and abroad and the actual logging and seismic data in the region,a large number of explanations are put forward.And we summarize the technical scheme of single-stage fault analysis of "fault propagation evolution mechanism guidance and the interpretation of well-logging and seisimic restraint".Under the guidance of growth and development mechanism,the three-dimensional spatial distribution of each fault is fine-grained and the accuracy of fault description is improved.In this study the specific results and understanding are as follows:(1)the regional experiences three periods of tectonic movement,each has different degrees of syngenetic fault phenomenon,suggests Sapu reservoir fracture has the characteristics of multiphase activities;(2)the breakpoint to verify and distribution analysis,detailed interpretation fault seismic horizon and fault near the main body section,to lay a solid foundation for the following;(3)we understand the growth of the big fault evolution causes and mechanism of fault has "panel growth,vertical installment evolution" characteristic;(4)the mechanism of fracture growth evolution,logging constrained seismic data,the formation of a large single phase fault identification method,a well off and more on the ownership of the more reasonable;(5)on the basis of the detailed fault interpretation,based on the fault growth mechanism to establish fault micro structure recognition method and standard of edge,quantitative characterization micro structure distribution range;(6)the synthetic analysis of tectonic,injection-production relation and potential sandbodies,optimizing selected 44 a favorable target area,including 12 kind of favorable area,11 second favorable area and three types of 21 favorable area.
