Abstract

Drilling apparatus comprises a rotatable drilling transmission shaft (14) for transmitting drilling torque down a bore hole. A tubular housing member (24) surrounds the shaft (14) and supports monitoring, control or logging equipment. To prevent the member (24) from rotating with the shaft (14), a plurality of springs (26) are mounted on the external surface of the member (24) and resiliently engage the bore hole wall (20).

Description

Title; Drilling Apparatus With Non-Rotating Member
Field of the Invention
This invention relates to drilling apparatus.
Background to the Invention
The invention is concerned with drilling apparatus comprising a rotatable drilling shaft which transmits drilling torque down a bore hole to a drill bit. The drilling shaft may be part of a drill string which extends from the surface, where the drill string is rotatably driven, to the drill bit carried by the lower end of the drill string. This is normally called rotary drilling. Alternatively, the drilling transmission .shaft may be driven by a turbine or positive displacement motor which is located down hole, immediately above the upper end of the drilling transmission shaft, and which is driven by drilling fluid pumped down the bore hole by a pump on the surface. In either of these alternative arrangements it is sometimes necessary to incorporate equipment such as logging or monitoring equipment (or equipment for controlling direction of drilling) which does not rotate with the drilling transmission shaft. It is therefore necessary to incorporate a member which is restrained against rotation, and the invention is concerned with drilling apparatus which is provided with anti-rotation means for this purpose.
According to the invention drilling apparatus comprises a rotatable drilling transmission shaft for transmitting drilling torque down a bore hole to a drill bit, a member which surrounds the transmission shaft and an anti- rotation means which engage the bore hole wall and restrain the member against rotation with the shaft, the anti-rotation means including a spring which resiliently engages the bore hole wall.
The spring is preferably one of a plurality of springs circu ferentially spaced around the member.
Each spring may be of metal (eg spring steel) or non-metal (eg fibreglass composite material). Each spring preferably has a radially outer surface which is coated with a wear-resisting material to minimise wear and abrasion.
Each spring may be in the form of a blade respective ends of which pass through mountings attached to the outer periphery of said member.
Drilling apparatus according to the invention will now be described by way of example with reference to the accompanying drawing which shows a portion of the drilling apparatus in diagrammatic sectional view.
Referring to the drawing, the drilling apparatus comprises a rotary drill string comprising standard components 10 and 12 between which is inserted a drilling transmission shaft 14 which transmits drilling torque from the component 10 to the component 12 and thereby transmits the drilling torque to a drill bit (not shown) carried at the lower end of the drill string. The drill string is hollow and the central passage 16 carries a supply of drilling fluid which is pumped from the surface (which is located to the left of the drawing) to the drill bit (which is located to the right of the drawing) as indicated by the arrow 18. The drill string is spaced from the bore hole wall 20 and this annular space accommodates the return flow of drilling fluid (including chippings removed by the drill bit) as shown by the arrow 22.
The shaft 14 is surrounded by a tubular housing member 24 which is prevented from rotating by means of anti-rotation means in the form of four circumferentially spaced springs 26 bearing on the bore hole wall 20. The springs 26 are equi-angularly spaced around the housing member 24 and are capable of elastic deformation in order to follow irregularities in the bore hole wall and provide- a frictional resistance to rotation of the housing 24. Each spring 26 provides a resistance to rotation equal to the radial force by which the spring bears on the bore hole wall multiplied by the coefficient of friction. The total resistance to rotation will be the sum of the individual forces resisting rotation at each of the four springs 26. The housing member 24 is supported by spaced bearings 28 and is protected from the ingress of drilling fluid by dynamic seals 30 which seal the housing member 24 to the respective adaptors 10 and 12 whilst allowing the adaptors 10 and 12 to rotate with respect to the housing 24.
Each spring 26 is in the form of a spring steel blade respective ends of which are located in mountings 32 attached at spaced positions to the outer periphery of the housing member 24. The end of each spring blade is capable of a floating movement in the corresponding mounting 32, as the spring moves inwards and outwards with irregularities in the bore hole wall 20. The natural resilience of each spring 26 causes the latter to maintain contact with the bore hole wall 20.
The springs 26 resist the tendency for the housing member 24 to rotate, this tendency resulting from:
1. Friction in bearings.
2. Torque reaction from the generation of electrical power.
3. Torque reaction from the generation of hydraulic power.
4. Friction between sealing faces.
5. Viscous transfer of torque.
It will be appreciated that the springs 26 move axially from left to right as shown in the drawing, as drilling proceeds. The shape of each spring 26 minimises resistance to axial movement.
The annular space between the drilling transmission shaft 14 and the housing member 24 is, between the spaced bearings 28, used to accommodate monitoring.control or logging equipment which monitors and controls the drilling course. Such equipment is attached to the inter periphery of the stationary housing member 24, at an axial position between the two bearings 28, so that the equipment is stationary and protected from drilling fluid.
