| 27 | A method and apparatus for releasing the fault on the bore crown during the boring process | JP2008526318 | 2006-08-11 | JP2009504950A | 2009-02-05 | モーシフニーク，ヨーゼフ |
| The invention relates to a method and a device for releasing a block or blockage on a bore-crown or drill bit (1) during a boring process, especially percussion boring or rotary percussion boring or drilling, for boring holes in the ground or rock, whereby a borehole is formed by a bore-crown (1) mounted on a boring rod or a drill rod assembly (2) and connected thereto and acted upon by the boring rod to generate a rotational movement and optionally a percussive movement. According to the invention, when the bore-crown (1) is blocked, preventing the continuation of the boring process and especially another rotational movement of the bore-crown (1), the bore-crown (1) is subjected to a linear movement in the opposite direction to the boring direction by means of the boring rod (2), and to a rotational movement in a direction opposing the direction of the rotational displacement during the boring process by means of a corresponding connection (7, 9) between the end of the boring rod (2) facing the bore-crown (1), and the bore-crown (1), independently of a rotary drive for carrying out the boring process. As a result the borehole can be bored in a simple manner after releasing the block on the bore-crown (1). | ||||||

| The performance of a double-cone device (1) is increased, not only by moving the gap or inlet openings (22) a short distance into the exit cone (47), but also by making the conicity υ3 (55) of the so-formed small diffuser less than the conicity υ2 (109) of the remaining part (53) of the exit cone. Double cone units (7, 60), particularly the ones with this improved diffuser, may be used in pump installations (1, 60), like well-pumps (1), where liquids must be pumped from great depths. | ||||||

| The present invention relates to methods and equipment for recovering use of a wellbore in circumstances where the well bore has become blocked by downhole equipment. The invention provides a method comprising the steps of separating, at a release joint, a portion of equipment from a jammed portion (6) of equipment; running the separated portion of equipment uphole out of the wellbore (100); running a deflector assembly (60) downhole into the wellbore (100); and deflecting a milling tool (64) from the wellbore into surrounding formation. The method is characterised by restricting relative movement between the deflector assembly (60) and the wellbore (100) by engaging, prior to deflecting the milling tool (64), the deflector assembly (60) with said jammed portion (6) of equipment. | ||||||

| A method for actuating or installing downhole equipment in a wellbore using non-acoustic signals (e.g. radio frequency signals) to locate, inventory, install, or actuate one downhole structure in relation to another downhole structure is shown in Figure 3. The method comprises the steps of: (a) providing a first downhole structure (12) that comprises a non-acoustic (e.g., radio frequency) identification transmitter unit (28) that stores an identification code and transmits a signal corresponding to the identification code; (b) providing a second downhole structure (32) that comprises a non-acoustic receiver unit (34) that can receive the signal transmitted by the non-acoustic identification transmitter unit, wherein one of the first downhole structure and the second downhole structure is secured at a given location in a subterranean wellbore, and the other is moveable in the wellbore; (c) placing the second downhole structure in close enough proximity to the first downhole structure so that the non-acoustic receiver unit can receive the signal transmitted by the non-acoustic identification transmitter unit; (d) comparing the identification code from the transmitter with a target code in the receiver; and (e) if the codes match, actuating or installing a downhole structure. | ||||||
| 38 | SAFETY JOINT | EP97941130.3 | 1997-09-25 | EP0928361B1 | 2004-02-04 | McGARIAN, Bruce; McGARIAN, Valentine, Haig |
| The present invention relates to safety joints which permit separation of a downhole assembly at the location of the joint. The invention provides a safety joint characterised by the provision of auxiliary interconnecting means on a body (2) for interconnecting said body (2) to an auxiliary shaft after removal of a main shaft (3) from said body (2). Axial loading between the auxiliary shaft and said body (2) may be thereby transferred. Furthermore, torque may also be transferred between the auxiliary shaft and said body (2) in a direction opposite to that in which torque may be transferred from the main shaft (3) to said body (2). Thus, the present invention allows a length of downhole assembly located above said body (2) to be removed from a wellbore by rotation of said length of assembly in a first direction and then allows rotation of said body (2) in the same first direction by means of the auxiliary shaft in an attempt to remove a length of assembly stuck in the wellbore downhole of said body (2). | ||||||

| Apparatus for recovering logging tools and the like from a wellbore as part of a drilling operation such as for oil wells, irrigation systems and the like. The apparatus comprises the use of a flexible connector member (44) in the form of a flexible wire rope, or strand, or cable which is provided with socket members (46, 48 or 146, 148) attached with resin (54) or by being swaged or crimped to the flexible member (44). The apparatus takes the place of the conventional rigid sinker bar assembly that causes safety concerns when used with a top drive housing. | ||||||
