ATTORNEY! METHOD AND APPARATUS FOR TELEMETERING INFORMATION THROUGH WELL BORES This application is a continuation-in-part of copending application Ser. No. 672,261 filed Oct. 2, 1967 for Method and Apparatus for Telemetering Information Through Well Bores, now abandoned.
BACKGROUND OF THE INVENTION The monitoring of changing conditions such as electrical formation resistivity, radioactivity, acoustic velocity, formation pressure, etc., in the remote confines of a well bore and the transmission of information reflecting such changes to a wellhead is a problem of long standing in the art.
Prior art attempts at solving this complex problem have included the locating of a sensing device in the well bore at some appropriate and often substantial depth and electrically connecting the sensor to a recorder or other indicator at the wellhead. This traditional solution is costly, vulnerable to interference, and usually quite complex. Yet, a knowledge of the variations in the conditions within a well bore may be essential to optimizing production both in permanent installations and, e.g., in the testing or drilling stages.
It is accordingly an object of the present invention to provide a novel method and apparatus whereby conditions existing in a well bore can be monitored at the wellhead without the need for connecting wiring.
Another object of the present invention is to provide a novel method and apparatus whereby the natural frequency of oscillation of a fluid body may be modified in response to changing conditions within the well.
Still another object is to provide a novel method and apparatus whereby the natural frequency of oscillation of an incompressible fluid body may be modified by varying the degree of fluid communication between the fluid body and a container of a compressible fluid.
A further object is to provide a novel method and apparatus whereby the energy necessary to convey information relative to a remote condition existing in a well bore to the wellhead may be introduced at the wellhead rather than within the well bore.
These and other objects and advantages of the present invention will become more fully apparent from the claims and from the following description when read in conjunction with the appended drawing.
THE DRAWING The FIGURE schematically illustrates a well and one embodiment of the apparatus for practicing the present invention.
THE PREFERRED EMBODIMENT Referring now to the drawing, a conventional well bore is illustrated, which has been provided with a conventional casing 12, extending from a wellhead l4, downwardly into the well bore 10. A well conduit string 16 extends downwardly from the wellhead 14 into a cavity 18, defined transversely by well bore 10, and vertically by one or more conventional packers 20 or the limits of the well bore 10. The presence of packer 20 is not necessary to the practicing of the present invention and cavity 18 may extend upwardly to the wellhead l4 and downwardly to the bottom (not shown) of the well bore 10. The conduit string 16 may terminate in an apertured conduit 22 or may as an alternative be open at the lower end 24 thereof to provide fluid communication with the cavity 18.
A conventional self-contained bore hole condition sensor 26 is installed within the cavity 18 of the well bore 10. The sensor 26 may be of any commercially available type and may be adapted to respond to any condition which may exist in a well bore. Parameters of interest may include electrical formation resistivity, radioactivity, acoustic velocity, or even formation pressure so long as the formation of interest is isolated from cavity l8.
Located in proximity to the condition sensor 26 is a pressure vessel 28, the configuration of which is not critical but which may conveniently take the form of an inverted chamber or tank having a relatively narrow neck portion 30 at the lower extremity thereof.
A convention valve 32 is installed in the neck portion 30 of the pressure vessel 28. Valve 32 is operably connected to an actuator 34 which operates to open and close the valve 32 in response to the value of the condition detected by sensor 26. Vessel 28, valve 32, actuator 34, and sensor 26 are mounted within a well bore. This mounting may be fixed in character and achieved with conventional well tool positioning means such as slips. It is also possible in certain circumstances for all or portions of the assembly to be mounted on a movable well tool.
The specific construction of the actuator 34 is not critical to the practicing of the present invention. Actuator 34 may, for example, consist of a simple mechanical linkage between the valve 32 and a bellows pressure detector isolated, of course, from the oscillatory pressures of the fluid body within cavity 18. Alternatively, the actuator may be a conventional sole noid, the position of which may be controlled by an electric current generated by a conventional scintillation detector and photomultiplier tube. The use of a battery powered, nonreversible electric motor driving against an appropriate mechanical bias such as a spring may also be utilized, the sensor taking the form of a condition responsive element in one arm of a battery energized conventional bridge circuit.
Pressure vessel 28 is at least partially filled with a compressible fluid such as air prior to installation within the well bore 10. The opening of valve 32 allows the lower portion 36 of the vessel 28 to fill with fluid from cavity 18. The compressible fluid is thus compressed by the fluid pressure of cavity 18 into the upper portion 38 of the pressure vessel 28.
Means are provided at the wellhead for imparting an oscillatory impulse to the fluid contained in cavity 18. In actual practice a satisfactory impulse has been obtained by pumping fluid from a conventional pump 40 of the reciprocating piston type into the tubing 42 and conduit string 16, and quickly clutching out" the pump 40 against a check valve 44 at a pressure between 400 and 600 pounds per square inch. In this manner the last stroke of the fluid displacing piston within pump 40 imparts a terminal pressure impulse to the fluid body. The fluid body at this time may be static," herein defined as a condition of non-flow.
The fluid body, i.e., the fluid within conduit string 16, cavity 18 and the lower portion 36 of the pressure vessel 28 provided valve 32 in the narrow neck portion 30 thereof is open, will then oscillate or undergo cyclical changes in pressure. By allowing this natural oscillation to continue without interference from additional pressure impulses, the fluid body will resonate.
The fluctuations in the pressure of the fluid body are detected at the wellhead 14 by a conventional and commercially available pressure transducer 46 and recorder 48. Recorder 48 may include pressure indicating means such as a bellows (not shown) positioned within the interior of conduit 16 and exposed to the pressure of the fluid body. This bellows, through conventional linkage arrangements or other force transmitting means, may be used to modulate the frequency of an electronically generated waveform or may be utilized to directly generate such a waveform by moving a coil through an electromagnetic field.
The resonant frequency of oscillation of a fluid column has been determined, as a part of this invention, to vary with the rigidity of the fluid column defining walls. Consequently, the opening and closing of the valve 32 in the neck portion 30 of the pressure vessel 28 modifies the resonant frequency of the fluid body within the well bore 10 by placing the interior of the pressure vessel into and out of fluid communication with the fluid body. With the valve 32 closed the resonating fluid body is contained entirely by rigid walls. With valve 32 open the fluid body includes the incompressible fluid in the lower portion 36 of pressure vessel 28. The fluid body thus is contained in part by the pressure of the compressible fluid in the upper portion 38 of the pressure vessel 28. The interface between the fluid body and the compressible fluid obviously lacks the solidity which would otherwise exist. Modifications in the position of the valve 32 are thus reflected as changes in the resonant frequency of the fluid body as detected and displayed in the recorder 48.
Numerous changes and modifications may be made in the specific embodiment of the present invention without departing from the true spirit or essential characteristics thereof. Those skilled in the difficult art of well drilling and familiar with the disclosure of this invention may well recognize additions, deletions, substitutions, or other modifications with reference to the disclosed techniques. The disclosed techniques are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
