摘要
中国油气企业对中国境内已开发油气田开展新钻井经济评价工作时,主要采用直接增量法。受诸多因素制约,海外已开发油气田新钻井的经济评价不能简单应用直接增量法。国内与国外的已开发油气田在合同模式、财税制度、开发生产期限、弃置费等方面存在明显差异。对于海外已开发油气田新钻井进行经济评价,需要考虑合同模式和财税制度的国别差异、评价期的选取、投资成本估算、弃置作业及弃置费处理这些关键影响因素,采用“有无对比法”评价新钻井项目的经济性。应以合同有效期和油田经济寿命期二者中的较短值为评价期。对投资成本的处理应遵循“相关性”原则。新钻井延期支付油田弃置费的时间价值依资源国、合同条款的具体规定而异。
Chinese oil and gas companies mainly adopt the direct incremental evaluation method when conducting economic evaluation of newly drilled wells in developed oil and gas fields in China.Due to many factors,the direct incremental method cannot simply be applied to the economic evaluation of new wells drilled in overseas developed oil and gas fields.There are obvious differences between domestic and overseas developed oil and gas fields in terms of contract mode,financial and tax system,development and production period,and abandonment fee.For the economic evaluation of new drilling wells in overseas developed oil and gas fields,it is necessary to take into account the country-specific differences in the contract model and tax system,the selection of the evaluation period,the estimation of the investment cost,the disposal operation and the treatment of the disposal fee as the key influencing factors,and to evaluate the economy of the new drilling project using the"with or without comparison method".The evaluation period should be based on the shorter between contract term and the economic life of the oilfield.The treatment of investment costs should follow the principle of"relevance".The time value of deferred field abandonment payments for new drilled wells varies according to the resource country and contract terms.
