The world is not as tidy a place as it appeared to be before the second world war, but not all modernist housing was a failure either.
世界已经不再像二战前呈现一副井井有序的模样，不过现代主义住宅也不都是失败之作。Therefore, take research on well control of horizontal well in deep water has great significance for the safety of deep-water drilling.
因此，进行深水水平井井控技术研究，对深水安全钻井具有重要意义。For specialty of well track in horizontal well, the risk and difficulty of operation are all higher than that of the common well.
由于水平井井眼轨迹的特殊性，施工风险和难度高于普通井。In smooth boreholes of constant diameter, the effect of the borehole is well understood and can be corrected for.
在井径不变、井壁光滑的井中测井，井眼影响容易校正。Casing window sidetracking drilling can resume old well productivity, gain a remarkable economic benefit.
在停产的老井井眼中进行套管开窗侧钻，可恢复老井产能，取得显著的经济效益。These indicated that beneath the stratigraphy where the first well was lost, drilling margin would increase.
这表明，在第一口井井位处的地层下面，钻井收益会增加。These two green promenades on both sides of the car and bike paths separated from the vehicle makes the bustling Well orderly.
这两条绿色长廊把汽车和两边自行车道分开，使得熙熙攘攘的车辆井井有序。The problems of hole trajectory control in cluster slim holes are studied emphatically in this paper.
重点探讨了小眼丛式井井眼轨迹控制问题。This paper introduces the control of cluster well trajectory for shallow viscous crude oil in District-9, Karamay Oilfield.
介绍了克拉玛依油田九区浅层稠油丛式井井眼轨迹控制情况。
