APPLICATION OF FAULT SEALING TO THE BOUNDARY DIVISION OF PETROLEUM SYSTEMS

The qualitative and quantitative study of fault opening or sealing and the analysis of petroleum systems are two fashionable research subjects in the domain of petroleum exploration at present.In the study of petroleum systems,the division of petroleum systems is critcal.It has very important significance to the objective evaluation of resource potential for petroleum systems and to the determination of favorable zones and traps for exploration.With the sealing or opening of faults,the geographic distributive ranges of petroleum systems decrease or increase,and the evaluation on the potential of petroleum exploration changes correspondingly.It this paper,the present situation of fault sealing research is reviewed,and it is applied to the analysis of petroleum systems in the Bachu uplift of the Tarim basin.
