摘要： 克拉玛依 砾岩油田现可采储量采出程度已达71.24%,综合含水率为70.7%.针对高含水期砾岩油藏的特点,既要综合应用有效增产措施达到较好的开发效果，还应制定增产措施经济界限,为措施投资提供决策依据。将高含水砾岩油藏经济极限含水率定义为准经济极限含水率和经济极限含水率两种。通过研究措施费用、措施变动成本和油价的变化,建立了措施增油经济界限与油价、措施费用、措施变动成本的关系图版。并以准噶尔盆地西北缘砾岩油藏I类、II类、II类典型油藏为案例,进行了克拉玛依砾岩油藏高含水期增产措施经济界限的定量研究和计算。该方法的推广应用,可有效地降低高含水砾岩油藏增产措施的综合运行成本,进-.步提高措施投资的营运效益。

Abstract: The conglomerate oilfield in northwestern margin of Junggar basin has its recovery percent of recoverable reserves of 71.24% andcomposite water cut of 70.7% at present. For the characteristics of the conglomerate reservoirs with high water cut, effctive stimulations shouldbe comprehensively applied to gain better exploitation effectiveness, and economical limitation for the stimulations be determined to providedecision-making basis for investment of the stimulations. 'The economical limitation water cut for highwater cut conglomerate reservoir is definedas quasi-economical limitation water cut and economical limitation water cut. According to changes of stimulation cost, operation varied cost andoil price, the chart related to the stimulation economical limitation and oil price, stimulation cost, operation varied cost is developed. And takingClass I, lI, III typical conglomerate reservoirs in northwestern margin of Junggar basin as examples, quantitative estimation and analysis aremade in the limitation. 'The application of this method will allow to effectively decrease the composite run cost of the stimulations and thus to fur-rtereyrereaecalateefstteiai Electronic Publishing House.
