摘要: 水平井的驱替流动在一定条件下近似于线性流,可以获得最大的驱替流量和高于垂直井的波及系数.大庆榆树林油田树平1井的开采实践说明该地区一口水平井产量大约相当于2~5.5口垂直井.随着水平钻井技术的不断提高和费用的下降,利用水平井的经济前景越来越好.建议对于大型水平多油层油田采用水平井和垂直井相结合的开采方法.

Abstract: This paper presents a fact that theproduction toward a horizontal well flood approachesto a linear flow in thin reservoirs. Significant increases in flow rate and in areal sweep effi-ciency with horizontal wells are obtained.The oil production of a horizontal well of DQ YLoil field is equal to that from 2~5.5 vertical welis.A further utilization of horizontal wells is to improve oil recoveries with an improvementin drilling technology and reduce well costs is suggested.Using a combination of a horizontalwell and vertical wells can improve oil recoveries in a strongly stratified reservoir.
