The Distribution Of Fault System And Its Controlling On Reservoir In Middle Of Jungar Basin

A large amount of oil and gas has been discovered in central Jungar as an important reso urce increasing block of SINOPEC after many years' exploration.however,in this subtle reserv oir with alien hydrocarbon source of this area,the faults can act as not only hydrocarbon mig ration channels,but also shelter of oil and gad migration.The faults paly a crucial role on hyd rocarbon migration and accumulation,therefore their controlling effects have become the ke y point of the study on Hydrocarbon reservoirs.Given the important role of oil and gas in the semi-fault traps,expand Faults alignment area,go flat slip fault system features a combination of style and space is more complex,and its activities in the area of fault sealing capacity of fault system currently have not yet achieved more in-depth understanding,still need to carry out careful research in this area.So the goal of this research is the analysis of geological and geophysical data combined use of multiple geophysical techniques,fine fracture system characterization,analysis of different types of fault basin distribution system,considered quasi-border development in the region of ancient punch strike-slip faults,strike-slip fault flower-shaped cross-section with a fault,cutting the substrate,occurrence steep characteristics,the plane has translated dislocation,en echelon,parallel distribution characteristics.Large parts of the basin margin slip,deep-lying parts of the basin slip away small amounts.Clear fault system cross section,flat characters and space combination style,build a three-dimensional geological model of quasi-static fracture system in the region.Evaluation of prospective strike-slip fault system in the area conducting effectiveness.By spending like strike-slip faults and hydrocarbon distribution relationship analysis,clear flower strike-slip fault of vertical hydrocarbon migration plays an important role.Analysis of fault transporting effectiveness factors,establish the effectiveness of the strike-slip faults conducting quantitative evaluation model to analyze the impact of fault seal performance for various reasons,find factors that play a decisive role,and to carry out quantitative studies of these factors,in order to achieve quantitative evaluation of fault sealing ability.
