DESCRIPTION:
BRIEF SUMMARY
STATEMENT OF THE PRIOR ART
So far as known to applicant, there are no prior art devices which enable non-rotatable drill string, such as coiled tubing, to be employed as drill string to drill directional, or deviated well bores, including horizontal well bores.
There are various types of directional drilling equipment well known to those skilled in the art of directional drilling that may be employed with a conventional rotary drill string formed of tubular members threadedly connected together to form the drill string which drill string is rotated by surface equipment of any well known type to drill a directional, or deviated well bore including a horizontal well bore. Down hole instruments, such as by way of example only, MWD (Measuring While Drilling), steering tools or gyroscopes, well known to those skilled in the art of directional drilling, are used to provide information in a form which is relayed to the earth's surface in any suitable manner, well known by those skilled in the art of directional drilling.
This information is interpreted in a manner well known by those skilled the art of directional drilling to show the direction of the well bore being drilled by the down hole motor and drill bit on the lower end of the drill string and to predict what change in position or orientation, if any, should be made in the down hole directional drilling equipment to assure that the down hole motor and drill bit on the lower end of the drill string will drill the well bore to the desired target area.
The orientation of the directional drilling equipment including the down hole motor and drill bit is presently accomplished by rotating the drill string by any suitable means such as tongs, or the like, at the earth's surface when the readings obtained from the instruments employed with the directional drilling equipment indicate the necessity to rotate the drill string to re-position the drill string in the well bore for re-orienting the down hole directional drilling equipment, including the down hole motor and drill bit on the lower end of the drill string so as to face the drill bit and down hole motor in the direction to continue drilling the well bore to assure that the well bore will hit a designated or desired target area.
The various types of down hole directional drilling equipment, surface and down hole instrumentation, surface equipment and software used to determine and dictate the orientation necessary for the drilling of a deviated well bore, including a horizontal well bore to a target area, is generally referred to as the steering system or guidance system for the drill bit.
The use of keys which engage in helical grooves in members in various devices is well known.
SUMMARY OF THE INVENTION
So far as known to applicant, it has been considered impossible to use a non-rotatable drill string to drill a deviated or horizontal well bore as there is, so far as known to applicant, no practical, economical way to D rotate the non-rotatable drill string to orient the down hole directional drilling equipment and instrumentation including the down hole motor and drill bit to drill the well bore in a desired direction. The present invention allows this to be accomplished in a relatively simple, inexpensive and quick manner.
The present invention overcomes the problems and obstacles heretofore presented in connection with employing coil tubing for performing operations in a well bore, particularly a deviated or horizontal well bore.
One object of the present invention is to provide a well tool assembly and method of use for down hole orienting and reorienting of a device in a well bore to accomplish a desired result.
An object of the present invention is to provide a down hole orienting tool for use with a non rotatable drill string to orient a drill bit to drill a well bore in a desired direction.
An object of the present invention is to provide apparatus for rotating a down hole device by a non-rotatable member.
A further object of the present invention is to provide method and apparatus for drilling
