开发中后期油藏对外合作项目经济评价模型建立及应用

Establishing and applying economic evaluation model of foreign cooperation projects in middle and later stages

摘要: 基于产品分成模式及现金流量法建立了符合处于开发中后期油藏自身特点的对外合作项目经济评价模型。模型通过引入R因子控制双方利润油分成比例，并规定费用回收限额及顺序，实现了对合作双方利润的合理控制和分配。通过对新疆油田某区块进行实例应用，模型准确完成合作双方经济效益的测算。经技术分析，当费用回收限额设定为55%～65%，R≤1新疆油田利润油分成比例设定为42%～50%时，对外合作项目能够保证合同者经济效益的同时实现新疆油田效益最大化，实现合作双方互利共赢。

Abstract: Based on the product sharing model and cash flow method, an economic evaluation model of foreign cooperation projects is established.The model controls profit oil distribution by R factor, stipulates the limit and order of cost recovery, so as to realize the reasonable control and distribution of the profits of the parties in cooperation.Through an application in a block of Xinjiang oilfield, the model accurately completes the calculation of economic benefits of both sides of cooperation.Through technical analysis, when the cost recovery limit is set at 55%-65%.R≤1, the profit-sharing ratio of Xinjiang oilfield is set to 42%-50%.It can ensure the economic benefits of both sides and realize mutual benefit and win-win situation.
