摘　　要：张海502FH井是大港油田在滩海地区布置的一口开窗侧钻水平井,完钻垂深为2857.45m,斜深为5387m,最大井斜为96.1°,水平段长602m,用φ155.6mm钻头钻进,井底水平位移为4128.55m。该井开窗侧钻及水平段使用由MISWACO公司提供的ULTRADRILTM水基钻井液。该体系可以抑制大多数活性页岩,提供良好的井壁稳定性;能包被钻屑,有利于井眼清洁;能很大程度地降低软泥岩对钻柱和钻头的粘附;具有高钻速和低的稀释率,是水敏性泥页岩钻进的优选体系。现场应用表明,该体系性能稳定,流变性好,现场配制及维护简便,携砂能力强,润滑防塌效果好,很好地解决了因水平位移大、井斜角大导致的井眼清洁、拖压、扭矩增大的问题。Well 502FH is a sidetracked horizontal well located at the beach area, with the vertical depth being 2857.45 m, the measured depth 5387 m, the maximum well angle 96.1°, and the length of the horizontal section 602 m. The horizontal section was drilled with φ 155.6 mm drill bits. The horizontal displacement of the bottom of the hole is 4128.55 m. A drilling fluid, ULTRADRIL^TM , provided by MISWACO, was used to drill the sidetracked section and the horizontal section. ULTRADRIL^TM has very good shale/cutting...
