The analysis of geological risks

the prediction of hydrocarbon resources exetents and the analysis of exploration and development condition are three independent factors in the assessment of zonules and traps.Three factor synthetic gueuing method is a guantitative assessement method proposed according to the above mentioned assessment mode.The method is derived from two factor gueuing method

the basic principle of which is to put the three factors in the same 3-D right angle coordinate system

and synthesize the three factors in one queuing coefficent by setting variable criterion and three factor queuinp formula.This coefficent could be used to evaluate and queu the traps and zonules directly.This method was used to evaluate and queu some structures in Wan'an Basin of Nansha sea area

and three types of traps were distingushed and exploration target areas were pointed.The results proved that this method is an ideal assessment manner for hydrocarbon exploration in deserts and sea areas.
