Eor is considered as an important technology for the strategic development of offshore oilfields in china 摘要在我国海上油田实施聚合物驱提高采收率是一项其有战略意义的举措，对于海洋石油的发展具有重要意义。
Core test was studied to prove the technical possibility of the polymer gel cooperated with microbial enhanced oil recovery 并进行了大直径长管填砂岩心驱替试验，结果表明，调驱联作技术能够明显地提高岩心采收率。
Usually , formula method , gas reservoir driving type method and analogy method , etc . , are used to determine the abandonment pressure or recovery 通常是采用公式法、气藏驱动类型法或比法等来确定气藏的废弃压力或采收率。
Multiple regression method has been widely applied in oilfield development , and common recovery empirical formula is one typical method 摘要多元回归在油田开发中得到了广泛的应用，常用的采收率经验公式就是一种典型应用。
At present , the oil field experiments that the main oil regions in our country apply polymer flooding to enhance crude oil recovery have obtained some achievements 目前，我国主要油区应用聚合物驱油提高采收率的矿场试验，已经取得了一定成果。
The findings of this paper will play an important directive role for the adjustment of development plan and further improvement of old field recovery efficiency of old oil field 本文的研究成果对孤岛油田南区开发调整，进一步提高老油田采收率具有重要指导作用。
This paper , by means of numerical simulation study , evaluates the sensitivities of different factors affecting the abandonment pressure and recovery of a gas reservoir in western sichuan 现以数值模拟为研究手段，以川西某气藏为研究对象，对影响废弃压力和采收率因素进行敏感性评价。
The proper injection allocation rate of well can effectively relieve the contradictions of plane , interlayer and inherent layers , and improve the effects of oilfield exploitation by waterflood or water drive process 合理的单井配置注量，可以有效缓解平面矛盾、层间矛盾、层内矛盾和提高水驱油田开发效果、水驱采收率。
Abstract : under - balanced drilling ( ubd ) technology has beenwidely used in oil drilling to improve oil recovery , minimize formation damage and eliminate drillingtroubles , while completion fluid technology is one ofthe key technologies 文摘:欠平衡钻井完井技术是保护油气层、提高采收率、克服各种钻井复杂问题的重要技术措施。
In the same test conditions , the oil recovery increased 7 . 7 and 6 . 2 percent of original oil in - place ( ooip ) more than that of polymer gel flooding and microbial flooding , respectively 该项技术不仅能够有效提高油藏采收率，而且也将会成为二次采油向三次采油过渡的技术先导，有广阔的发展前景和应用价值，也为发展三次采油技术奠定了良好基础。
