摘　　要：针对大庆油田外围区块油层薄、空间分布不均衡,老区低/停产井增多,非常规致密油埋藏深、地质情况复杂、岩石可钻性差等难点,开展了超薄油层水平井、分支井、超短半径水平井、三维绕障水平井和工厂化作业水平井等一系列行之有效的钻井技术研究与应用,形成了一套适合于大庆油田地质特点的水平并钻井配套技术.通过简要回顾大庆油田30年来水平井发展历程,详细介绍了油田现阶段水平井开发的钻井技术现状,并提出未来一段时间的发展方向。In view of the characteristics and difficulties of the peripheral blocks in Daqing Oilfield,such as the thin oil reservoirs,non-uniform spatial distribution,increasing numbers of the stripper and dead wells in the old areas,deep unconventional tight oil reservoirs,complicated geological conditions,poor drillability and so on,a series of effective drilling techniques have been researched and applied,including ultra-thin reservoir horizontal wells,multilateral wells,ultra-short radius horizontal wells,3D bypassing horizontal wells,＂factory-like＂ operation horizontal wells and so forth,finally a set of the matching techniques for the horizontal well drilling which are suited to Daqing Oilfield are established.Through brief review of 30-year horizontal well development history in Daqing Oilfield,the current technical status of the horizontal well drilling is introduced in detail,and furthermore its development orientation in the future is also prospected.
