摘要： A method for assembling a down-the-hole drilling apparatus including a drilling device including a casing and a drilling unit arranged during drilling in connection with the casing. The drilling unit includes a drilling head including a drilling arrangement including a first drilling member for drilling a center hole and a second drilling member for reaming the center hole. The drilling members are mutually power transmittingly coupled during drilling to cooperate for rotational, feeding and/or hammering, and removably coupled to enable removal of the first drilling member from a hole. The casing is arranged to be pulled into the hole through a shoulder arranged at an end of the casing. At an opposite end of the drilling arrangement with respect to a drilling surface, is arranged a skirt including a radial internal shoulder for pulling the casing into the hole by cooperation of the internal shoulder and an external shoulder at the end of the casing.

摘要： Collection device (10) for connecting a drilling tool (7), such as a bit, to the end of a drilling column, in which the connection device comprises a first element (5), with a first end, intended to be connected to the end of the drilling column, and a second element (12), with a second end, intended to be connected to the drilling tool, in which the second element is fixed to the first element so as to allow a translational movement in a longitudinal direction in order to make it possible to change the distance between this first end and this second end, characterized in that the connection device comprises a "pusher" structure for transmitting a thrust force from this first element towards the second element, comprising a set of "Belleville" washers making it possible to ensure that said thrust force, from this first element toward the second element, is substantially constant in any position of the second element with respect to the first element.

摘要： The invention relates to a method and an assembly for the rapid connection and separation of interconnectable elements (4, 6), in particular tubes or rods and/or drive elements and/or machining elements that can fixed thereto, such as for example drill bits or similar. An element (4) comprising a profiled end piece (9) is inserted into a corresponding receiving opening (11) of the element (6) to be interconnected and/or an adapter or connecting piece (7), in particular a bushing or sleeve, and is connected in a non-positive fit to the second element (6). The invention is characterised in that in order to connect and separate the two interconnectable elements (4, 6), the profiled end piece (9), after having been displaced in an axial or connection direction (12), is rotated by a sub-region (15) of the receiving opening (11), which is provided with a profile that complements the end piece, in relation to said receiving opening (11) in a sub-region (13) of the opening (11), which has an increased internal cross-section, and is then displaced in turn in an axial direction (12) into another sub-region (10) of the receiving opening (11), which is provided with a profile that complements the end piece (9). The invention permits a rapid and simple connection and separation of said elements as a result of a simple design.

摘要： It is provided a tool and its operating procedure, to protect any device while lowering into a well, and especially hydraulic devices such as sensors with expandable arms or inflatable elements such as packers.
The protection is mainly important in the open hole of highly deviated or horizontal wells, for any device equipped with external seal element, delicate sensor or articulated parts.
This tool features an automatic sequence controlled by a single dart or a single ball launched into the running string from the surface: when the dart or the ball lands on its seat, the pressure build-up is initially applied to a piston to extract the device from the protector without exposing it to any differential pressure, then it is automatically applied to the device itself for actuation as soon as the device is entirely pulled out of the protector.摘要翻译： 它提供了一个工具及其操作程序，以保护任何设备，同时降入井中，特别是液压设备，如带可扩展臂的传感器或包装机等可充气元件。 对于配备有外部密封元件，精密传感器或铰接部件的任何装置，保护对于高度偏差或水平井的裸眼井尤为重要。 该工具具有自动程序，由单个飞镖或单个球体从表面发射到跑线中：当飞镖或球体落在其座位上时，压力积聚最初施加到活塞以提取装置 从保护装置上将其暴露在任何压差下，一旦装置完全从保护装置中拉出，装置自动将其自动施加到装置上。
