        曙光油田经过几十年的勘探开发,目前已进入中后期开发阶段。处于这一阶段的油田面临着新探明储量接替不足、剩余可采储量减少、开采难度增加、油气生产成本上升等问题。随着油田措施投入的逐年增大,措施优选与评价成为目前油田开发的重要课题。本文在针对曙光油田现行评价方法存在需要解决的系列问题,在目前国内外研究的理论基础之上,研究确立了适合曙光油田开发实际的油井措施评价期、措施投入产出的计算方法和综合效益评价法、单位相对变动成本评价法、技术评价法相结合油井措施效果评价体系。并对2008年油田措施将措施评价期按有效期和周期分类进行了效果评价。研究结果表明:措施投入是否合理对曙光油田生产经营影响极大;以股份公司下达的单位操作成本指标代替原油价格,作为评价油井收入的标准,更加具有现实意义;综合效益评价法、单井相对变动成本评价法与技术评价法相结合,使得油井措施评价体系更完善。
    After decades of and exploitation, Shuguang Oil Field has now entered the mid-to late stage of development. The oil field at this stage is facing new issues, such as the lack of increased prospective reserves to replace, the decreasing in the remaining recoverable reserves, the difficulty increasing in oil exploration, and the rising of the cost of gas production etc. With the increasing investment in oil field measures annually, the optimization and evaluation of the measures becomes an important subject of the oil exploration at present.This thesis probes into a series of exist problems that need to be solved in the current evaluation method for Shuguang oil field, at the base of current domestic and foreign research theory, established a suitable evaluation period and a evaluation system of practical development for Shuguang Oil Field. The system is a combination of the input-output calculation method, the evaluation method in comprehensive benefits, single-well change cost comparatively and Technology Assessment. What’s more, on account of oil measures in 2008, it also gives an effectiveness evaluation about evaluation period according to the period of validity and periodic classification.The results show that whether measures put into practice is reasonable or not has a great impact on oil production and operation, and making unit operating cost target which ordered by stock companies superseded crude oil prices as a standard of oil wells income even more practical. All in all, the evaluation system on oil measures will become more and more perfect under the combination of the input-output calculation method, the evaluation method in comprehensive benefits, single-well change cost comparatively and Technology Assessment.
