油井措施最低增油量计算方法探讨

为了提高油井措施的投资效果，减少无效措施投入，合理利用有效的措施费用，提出油井增产措施最低增油量的概念；利用技术经济学理论，推导出计算油井措施最低增油量的计算方法。以辽河油田SG采油厂1737井次10类措施的实施效果为实例，证明计算油井措施最低增油量可以全面而客观地评价油井措施的效益状况，有功于科学筛选和确定油井措施，按效益第一的理念经管管理油藏。图1表1参7

Calculation of minimum oil production increment cutoff of oil well work-over

To enhance the investment effect of well work over, reducing investment of no effect, making good use of work over budget, the authors proposed the concept of minimum oil production increment cutoff of oil well work over, giving the algorithm of calculating the minimum oil production increment cutoff of oil well work over according to the theory of technological economics. We took 1737 instances of 10 categories of well work over in SG Oil Production Plant of Liaohe Oilfield as examples showing that the calculation of the minimum oil increment cutoff can evaluate the economic result of the well work over objectively and thoroughly. It can be used effectively for the screening of work over plans, managing the reservoirs according to the norm that economics plays the key role in reservoir management.
