原油产量是油田企业生存的基础,而经济效益问题发展的关键所在.本文以技术经济学的投入产出理论为基础,提出了确定油田(区块)效益状况的判别方法.按照投入、产出平衡原理,将油田(区块)分为4类:效益一类、效益二类、效益三类和效益四类;同时结合油田生产实际,研究提出了油气成本费用分摊办法.以辽河油田为例,对2001年的效益状况进行了综合评价,进一步验证了该方法的可行性和适用性.

Because there is no methods for systematic evaluation of benefit output available to date,it is difficult to quantitatively describe benefit from an old oilfield.This study developed a model and presented a method for estimating the benefit output,in light of productive regularity of an old oilfield and incoming time-cost function,integrated with production indexes and economic factors.It is indicated that the method is relatively comprehensive,the equations are practically identified by field data.Hence,it is of importance for related departments to evaluate the economic benefit of an old oil field.
