麻烦果友帮忙翻译一下下列钻井句子 [复制链接]

1.The BHA generally consists of a pilot bit and underreamer
2.The BHA is attached to a drill lock that fits into a full bore landing sub on the bottom of the casing in such a way that it can be retrieved with a wireline unit without needing to trip pipe out of the well. The wireline retrievable drill lock assembly is the heart of the casing drilling system. It lands in a lower section of casing consisting of a casing shoe, torque lock profile and axial no-go and lock profile located in a specially machined collar section (Fig. 2). The drill lock engages both a fluted profile to transmit rotational torque from the casing to the drilling assembly and an internal flush no-go and axial lock profile to transfer compressive and tensional loads to the BHA. A stabilizer on the BHA positioned opposite the casing shoe reduces lateral motion of the assembly inside the casing. The casing shoe is normally dressed with hard material to ensure that a full gauge hole is drilled ahead of the casing, but it also provides a torque indication if the underreamer drills undergauge. Centralizers on the casing stabilize it within the borehole and prevent wear on the couplings.
3.There are two types of CDS: internal – for greater casing radius, and external – for smaller casing radius

回复坐看云起 ：要不我把英语原文发给你，你看到底是不是作业，本人上班19年还要写作业啊，英语原文那是萨格勒布一个学生写的钻井水平井论文，同事对原文的翻译持不同意见，才拿出来讨论的啊。如果真的不让发了，那又有什么影响那。

1.The BHA generally consists of a pilot bit and underreamer
井下钻具组合一般包括一只领眼钻头和一只扩眼钻头。

井下钻具组合带有一只配装到套管底部全井眼联顶短节上的钻井锁，该锁可用一种不需起出钻柱的方式使用电缆工具加以回收。带电缆可回收的钻井锁组合是套管钻井的核心部分。它处在套管的较低部位，位于经特殊加工的接箍内、由套管鞋、扭矩锁紧装置、心轴止偏和锁紧部分组成（图2）。钻井锁通过使用槽型纹将转动扭矩从套管传到钻具组合、同时使用内部平接止动和心轴锁紧装置将压缩和拉张负荷传送到钻具组合。钻具组合上有扶正器可使套管鞋反向定位以减少套管内钻具组合的侧向移动。套管鞋上通常镶有坚硬材料以确保套管钻过的地层是全井眼的，但同时如果扩眼钻头欠尺寸钻进就会有扭矩变化加以指示。套管上的扶正器用以使套管在井眼内居中并确保不磨损接箍。
3.There are two types of CDS: internal – for greater casing radius, and external – for smaller casing radius
有两类套管钻井系统：内部型－用于较大的套管半径范围，外部型－用于较小套管半径范围。
