Study On The Optimization Decision Model Of Favorable Petroleum Accumulation Trap

The objective of petroleum exploration is hankering for most profit, and takesobtaining maximum reserves with least risk and cost as the principle. Petroleumexploration decision-making of the program has a direct impact on the ultimatebenefit of the petroleum exploration. Taking trap risk, investment and reserverequirements into account, the optimization decision model of favorable petroleumaccumulation trap is established according to optimization theory in operationalresearch. It can supply more scientific foundations for the petroleum explorationdecision about traps.First this paper has summarized the optimization theory, expounded someimportant concepts such as optimization variables, objective function and constraintconditions; also including some mathematical programming methods such as goalprogramming,linear programming and integer programming. Secondly the trapgeological evaluation, trap resources calculation, trap economic evaluation are studied.Thirdly according to the basic requirements and steps of establishing optimizationdecision mode, considering the above factors, establish the optimization decisionmodel of favorable petroleum accumulation trap.The empirical research of Qikou sag, based on the geological situation of Qikousag, establishes quantitative evaluation standard system for Qikou sag geological datain order to quantitative geological data. By changing the priority of decision-makingtarget and constraint conditions to test the validity of the model, it turns out that themodel can better meet the requirements of trap combinatorial optimization, offeringmore scientific foundations for the petroleum exploration decision about traps.
