Abstract: According to the characteristics of oil and gas exploration both integratively and finely,concerning the trap preexploration requires the trap evaluation research conducted quickly and timely to feedback evaluation for multiple potential traps to meet the requirement of scientific and optimal choice of the drilling targets,in this paper,however,based on its essentials,important contents and realizing procedures of the trap evaluation,the conception of integrated evaluation of trap is put forward and its connotation analyzed briefly,the geologic ideal,mathematic model and simulation idea are formed,the main function modes of the trap evaluation system is designed and this software developed,at last,the integrated evaluation and optimal choice which takes the computer as its powerful support built up.The quick interaction among the hardware,software,decisionmaker and evaluation information is realized by applying the advanced computer and communication technology to simulate the integrated evaluation procedure of trap,and it would provide the qualitative and quantitative references to the scientific decisionmaking of exploration targets with timely and intellectually,thus the scientific and reliable decisionmaking would be achieved.
