Research on Measure Programming in Oilfield Development

The project optimization of measures will be helpful economic benefits. In this paper, the measure programming to raise the oilfield development influencing factors were analyzed and the measure economic benefits were appraised. With consideration on the factors such as measure effect, potential, water cut and expense, a profit biggest nonlinear measure programming model was presented. Compared with the existing models, this model considers the influential factors more comprehensively. The time value of capital has been considered, at the same time the restraint condition has been led into to satisfy the nonlinear relation among measure oil increment, implement well frequency and expense. This model was solved by adaptive realcoding genetic algorithm. Application example shows that software based on this model has advantages of rapid computational speed and strong operability. The result can efficiently guide the programming of oilfield measure, and make the oilfield development adjustment get more economic benefits.
