摘　　要：针对WZ复杂油田的构造、储层及剩余油潜力等特点,总结了应用小井眼侧钻水平井技术对有潜力的油层按剩余油不同类型的分布情况采用不同的设计方法进行钻穿目的油层的应用情况。现场实施7口井,均达到了预期设计目的,投产效果良好。这项技术的应用表明,在复杂断块油藏开发中后期,结合剩余油分布特点,采用先进配套的钻井技术,油藏潜力可以得到充分挖掘,并能取得良好的开发效果和经济效益。According to the characteristics of structure,reservoir and remaining oil potential in complicated WZ Oil Field,this paper summarizes application of slim hole sidetrack horizontal wells in reservoirs with different types of remaining oil distribution with different design method for penetrating target zones.7 wells are drilled in the field,and all of them reach the object of design.The application of this technique shows that,in the middle and later stage of development of complex fault block reservoirs,advanced drilling technique can be used combining with remaining oil distribution so as to tap the potential of reservoirs and achieve more economic benefit.
