Abstract:
When the oil-gas field production enters the development mid and late part stage, well stimulation needs to be implemented on the oil well unceasingly in order to slow down the crude oil output decreasing progressively. Choosing suitable opportunity to carry on the work is one of the important methods of controlling cost and enhancing benefit. If the measure expense is regarded as an investment, then investment recycling is the basis that can judge whether the well stimulation is feasible or not. Based on the analysis of the cost and the income of well stimulation from economic angle, the best opportunity to implement the well stimulation and an output model of measure end point were given. The results show that the best time is when the profit of well equals the cost, and the constructed model can be used for assessing whether this measure has economic value or not, which provides the theory basis for the decision-making using single well stimulation.
Key words:  single well  well stimulation  measure output  decision-making model
