The Oilfield Development Single Well Economic Boundary Analysis Model And Its Application

As for oilfield development,oil production gradually declined,increasing moisture content,the inceasing difficulty exploitation and production costs are rising,every one single well production may not be contented enterprise management goal,so need to study the economic boundaries of single well to guide the smooth development of the oil-field business activities,improve the economic benefits of the overall oilfield development,provide theoretical basis and technical support for the fine management of oilfield enterprises.Through the oilfield development initial period,middle period,mid-late and late stage and the characteristics of the four development,changes and analysis in output and cost,determine the single well cost allocation and accounting methods,special calculation of tax is related to crude oil production,crude oil prices,crude oil commodity rate,operating costs and other administrative costs,operating expenses and the tax rate,combining the actual management of oil-field,the integrated use of net present value method,the dynamic break-even method and marginal analysis principle,we establish economic boundary analysis model of a single well in the four stages of oilfield development,including oil production,investment,operation cost and oil price, and applied to calculate the economic boundary model of single well in certain oil-field different stages.The research on single well economic boundary can be evaluated from various angle the economic benefit of a single well, to ensure that the every ton production of single well is profitable for oilfield,to maximize the realization of effective decision-making basis,was the deepening of the oilfield fine management.To reduce costs,achieve modernization management and improve the decision-making level of oil-field development,petroleum enterprises has the universal significance.
