商业油流标准确定方法探讨

以市场经济学原理为基础、以油气勘探开发实践为前提,详细分析论述了商业油流标准与工业油流标准的差异和确定商业油流标准主要因素,提出了确定商业油流标准的基本思路。通过储量技术经济评价“倒推”法,建立了整装油田和“三小”(小背斜、小断块、小砂体)油藏商业油流标准与原油市场销售价格、埋藏深度之间的关系图版及其二元函数方程。其意义在于将商业油流标准引入到油藏早期评价中,代替原来不能反映原油市场销售状况的工业油流标准,由静态标准界定油井工业价值转变为由动态标准界定油井商业价值,使商业油流标准能够随着市场原油销售价格、埋藏深度、油田储量规模及油田开发经营管理状况而不断地变化。

An Approach for Determination of Commercial Oil-Gas Flow Standard

This study discussed in detail the differences between commercial oil-gas flow standard and industrial oil-gas flow standard based on market economic principle and in view of practice for petroleum exploration and develop-ment,proposed basic idea for determination of commercial oil-gas flow standard,and establish chart of commercial oil-gas flow standard for an integrated oilfield and reservoir with"three lows "vs crude marketing price and reservoir-buried depth as well as its binary functional equation,by means of"reverse-derived method"for tech-economic assessment of reserves.It means that introduction of commercial oil-gas flow standard into early reservoir evaluation can re place origi-nal industrial oil-gas flow standard that could not reflect crude marketing status,thus converting industrial value of oil wells defined by static standard into commercial value of oil wells by dynamic standard.The commercial oil-gas flow standard is allowed to continuously change with crude marketing price,burial depth,reserve scale and operating man-agement of field.
