【摘要】 本文通过大量的现场调研,在对目前国内主要的大油田开发指标及投资、生产成本等经济指标资料分析的基础上,研究了符合油田开发生产实际及适应水驱开发油田各类增产措施的经济界限模型,即新井初期最低产量界限、开发投资上限、成本上限、价格下限、单井控制储量下限、经济极限井距等模型。这些模型的建立可为开发部署和生产决策提供经济效益依据。更多还原

【Abstract】 At the article,with a lot of investigation on site,the development indices and economical indices,such as investment and productive cost at Chinese main big oilfields are studied. On the foundation,models for economical circumscription suitable to development and production practice in various oilfields and to increasing production measures at water-flood oilfields are studied,including models about minimal productivity threshold for new oil wells,upper limit of development investment,upper limit of cost, the lowest limit of price,low limit of possible reserve around a single well,economical limited space between wells, and etc. The established models can play the role of base to plan exploitation and to suggest economical benefit for productive decision.更多还原
