Study On Remaining Oil Distribution And Potential Explosive Measures In XM Well Area

XM well area is a complex faulted block reservoir forming by the cut of multiple fracture.The work area possesses complex geological structure and the oil field productivity is affected by structure characteristics,change of sedimentary microfacies,spatial distribution of sandstone and variable physical properties.The existing well pattern control is low and the development effect is poor.The integrated system of Karamay reservoir in XM1、2、3 area is relatively weak,and some basic data are accumulated in the development process,but it has not been well applied.Oilfield development so far,in many ways need to solve the problem.Injection and production wells to be further improved.The number of inefficient wells increased gradually,the output decreased rapidly,the dynamic monitoring data was few,the sedimentary facies,strata,lithology,tectonics and fault development were to be further implemented.Through the description of fine reservoir,we can understand the characteristics of reservoir structure,sediments,reservoir development,study its influence on oil and gas accumulation,production characteristics,recalculate reserves and oil-bearing area,analyze and evaluate the development effect,combine numerical simulation,Understand the current distribution of remaining oil,study the corresponding relationship between injection and production systems,development of rational development policies,slowing down oilfields and improving reservoir development.Application of reservoir engineering analysis method to evaluate the effect of water development law,water injection effect,well pattern adaptability,recoverable reserves and measures effect on XM1、2、3 well area;the numerical analysis method was used to analyze the remaining oil types and values in the well area;according to the results of reservoir evaluation and residual oil analysis,the adjustment measures such as hole filling,fracturing,transfer and encryption are put forward.Determine the well pattern encryption program for the next step to adjust the program,and calculate the next 15 years of production time can improve the degree of recovery and oil production speed.
