摘要(Abstract):
运用模糊综合评判和层次分析理论,结合油藏的实际特征参数,建立水平井开发效果综合评价指标体系及多因素综合评价方法,开发评价软件,完成了240口水平井开发效果综合评价。通过深入分析影响开发效果的主要因素,明确了大庆外围葡萄花油层水平井开发存在的主要问题,并提供了调整治理依据。实际应用表明,该方法方便、快捷、针对性强,可为水平井评价提供有效手段。
By means of the theories of fuzzy comprehensive evaluation and analytic hierarchy process,and furthermore integrating with the actual characterized parameters of the oil reservoirs,the comprehensive evaluating index system and multi-factor comprehensive evaluating method are established for the development effects of the horizontal well,and then the evaluating softwares are developed,finally the comprehensive evaluations of the development effects for 240 horizontal wells are achieved.Through the deep analyses of the main influencing factors on the development effects,the principal problems existed in the horizontal well development of Putaohua layers in Daqing periphery oilfields are made clear and moreover the adjusting countermeasures are provided.The practical application shows that this method is convenient,fast and highly targeted,and can provide the effective means for the evaluation of the horizontal well.
