三元复合驱,即碱-表面活性剂-聚合物(APS)驱,是一种先进的水驱技术,可使原油采收率提高26%~30%,其成本为$2/bbl至$4.5/bbl。矿场方案的经济效果经验表明,在一次采油后立即实施ASP驱与在水驱中后期实施ASP驱,是大不相同的。在怀俄明州的保德河地中,1987年实施的1.295×106bbl孔隙体积的WeestkiehlMinnelusaASP驱方案,是最完善的矿场ASP驱方案。孔隙体积。即指某一油藏中为油、水和气所占据的空间。Minnelusa油藏通常都是水驱替的。而WestKiehl油藏。含有24°API原油,则是在一次采油后采用ASP溶液驱的。该方案是由TerraResources提出,PacificEnterprises购置和HuntOil完成的。最近,大庆油田实施了一个拥有1.279×106bbl孔隙体积的ASP驱的三次采油示范方案。该方案是1994年9月在大庆油田中区西部实施的,并开始了开采35°API原油。大庆是1960年开始普遍性水驱的,而ASP先导性水驱则是1993年才开始的。
ASP flooding, the alkali-surfactant-polymer (APS) flooding, is an advanced waterflood technology that increases oil recovery by 26% to 30% at a cost of $ 2 / bbl to $ 4.5 / bbl. Economic Experience from the Mines Program Experience shows that implementing ASP flooding immediately after an oil recovery is quite different from implementing ASP flooding in the middle and late stages of water flooding. In the Baode River in Wyoming, the Weestkiehl Minnelusa ASP flooding scheme of 1.295 × 106bbl pore volume implemented in 1987 is the most complete ASP flooding program in the field. Pore volume. Refers to a reservoir of oil, water and gas occupied space. Minnelusa reservoirs are usually flooded with water. WestKiehl reservoir. Containing 24 ° API crude oil, it is driven by ASP solution after an oil recovery. The program was proposed by Terra Resources, purchased by Pacific Enterprises and completed by HuntOil. Recently, Daqing Oilfield implemented an ASP flooding demonstration project with 1.279 × 106bbl pore volume. The program was implemented in September 1994 in the western part of Daqing Oilfield and started the exploitation of 35 ° API crude oil. Daqing was universally flooded in 1960, while ASP-led flooding did not begin until 1993.
