Description
SPECIFICATION
Method and apparatus for communicating with downhole measurement-while-drilling equipment when said equipment is on the surface
The present invention is directed to a method and apparatus which is used in conjunction with down hole measurement-while-drilling equipment es- tablish communication therewith while the equipment-commonly known as a sub - is on the surface.
Recent developments in measurement-whiledrilling equipment has produced technological changes in that the down hole equipment is able to accumulate a substantial amount of information, such as detailed descriptions of the various strata through which the drill is passing. Much ofthis information is extremely important, but not essential tothe on-going drilling operation. The drilling oper ation would require all ofthe details ofthe drill bit orientation, so asto correct the advancing boring operation and would be less concerned with the actual strata being penetrated. Thus, the usual telemetry that is provided, either with a mud pulsing system or hard wired system would give priority to the boring information and store the more detailed information concerning the various strata.Other known downhole equipment only records formation data forsubsequent recovery and evaluation. It is then possible to recover any stored information when the downhole equipment is periodically returned to the surface for bit replacement.
Prior systems for recovery of the stored data have employed direct electrical connections, which re quireanapertureto beformed inthewall ofthe downholeequipmentsub. Having an aperture inthe wall ofthe sub creates the problem of weakening the structure creating the possibility offracturing the sub with the possible resulting loss of the down hole equipment requiring an expensive fishing recovery operation. Other prior art systems have required breaking open of the drill string, at the surface, to either recover recording means itself or gain access totherecording madewhiledownhole.
Measurement-while-drilling resistivity sensors are generallytransmitters and receivers of either the current (conduction) type or induction type. Current type sensors include electrodes which are mounted on the surface of the sub for injecting and receiving cur rentdirectly into andfrom the drilling mud andformation immediately adjacent to the sub. Induction type sensors include antenna coils on the surface ofthe sub for inducing and detecting currents into and from the surrounding drilling fluid and formation.
An object ofthe present invention is to make it possibleto provide a method and apparatusforcommunicating with a measurement-while-drilling sub when the down hole equipment is at the surface and without the need of special connections through a bore or port in the sub. The present invention aims to eliminate this additional port providing a safer, more reliable and easily operated system.
The present invention employs either electrodes or antenna coils to provide an electrical connection between data accumulation and storage circuits within the instrument sub and a data storage and pro
cessing device at the surface. The present invention connectsorcouplesa surface deployed transmitter and receiver with the measurement-while-drilling re sistivity sensor receiver and transmitter, respectively, preferably while the instrument sub is at the surface, for example during changing of the drilling bit.The surface deployed transmitter and re ceivercoupled to the sub circuits have the capability of sending operating commands to the measurement-while-drilling sub and receiving from the sub data collected while the sub was downhole. The cir- cuits within the measurement-while-drilling tool must permit data stored within the sub to be transmitted through the electrode/antenna by temporarily disconnecting or blocking the electrode/antenna from its normal operating circuitry (or limiting such operation) to allowtransmittal ofthe stored data. For example, the surface equipment may activate a switching mechanism to temporarily perm it the re sistivitydevicetofunction as a data transmitting system instead of a resistivity measuring (data accumulation) system.
An embodiment of the present invention will now be described by way of example with reference to the accompanying drawing in which:
The single Figure shows a schematic section through atypical instru ment su b of a downhole assembly atthe surface and coupled to communication equipment in accordance with the present inven- tion.
The single Figure schematically illustrates the present invention as it would be used in conjunction with a known down hole measurement-while-drilling instrumentation package. The equipment sub 10 is formed of high strength steel and has an axial bore 12 and an annular cavity 14 in which are placed a transmitter 16, a receiver 18, an electrode/antenna array 20 and a data storage 22. It should be here noted that the present invention will applyto any type of downhole equipment having a transmitter and a receiver operating at any frequency with the primary purpose of gathering borehole information. If the equipment is an electrical sensor, then it can be of a conductive or inductive type, and if it is, then, the conductive type requires electrodes and the inductive type requires antenna.The electrode/antenna array 20 is accordingly mounted at or on the sub's surface with eithera single arrayfortransmitting and receiving or with separate sections for transmitting and receiving. It would be noted that the present invention would also applyto acoustical equipment in the sonic range or any other type of measurement equip- ment operating in any frequency range with appropriate transmitting and receiving means mounted on the sub.
The operation ofthe measurement-while-drilling equipment is quite conventional with the information being gathered while the equipment is operating down hole and, in appropriate cases, only that data which is necessary to the boring operation being transmittedtothe surface. The remaining information, such as strata configurations, would be placed into the storage for readout at a subsequenttime.
The down hole equipment could also be a system which would only record while downhole, with all data being recovered when the instrument sub is at the surface.
Asurface communicatorshown generally at 24 includes a transmitter 26, a receiver 28, and surface circuits 30 for data acquisistion and system control. The surfacecommunicator24 must be compatiblewith the down hole equipment so that if the downhole equipment is of the inductivetype, the surface equipment would likewise be of the inductive type. The transmitter 26 and receiver 28 ofthe communicator 24, forthe inductive example, would be placed within transmitting range of the equipment sub 10 when the sub is at the surface,for example when the down hole equipment had been returned to the surface for bit replacement. In a conduction orcurrenttypesystem, there would have to be electrical contact between the electrodes as shown in the drawing.While the equipment sub is at the surface, and without being detached from the drill string orwithoutthe sub 10 being especially penetrated, the surface com munica- tor 24 is brought to a position where the electrode/ antenna of the transmitter 26 and receiver 28 can contact or be coupled to the receiver and transmitter electrode/antenna array 20 ofthe equipment sub 10.
The surface equipment would then instructthe downholeequipmentbythetransmitter26sending instructions through array 20 and the receiver 18for the data storage 22 to read out and transmit the stored information through the transmitter 16 and the array 20, the information being received by receiver 28 and sentto the circuits 30 where the data will be stored and/or processed accordingly. Once the data transmission has been completed, it is possible to either reprogram or instruct the downhole equipment by transmitting the appropriate information from the surface circuits 30 through thetransmitter 26 to the array 20, the receiver 18 and into the data storage 22.The type of information that could bestored would include instructions forthe data measuring/acquisition system of the sub 10 regarding anticipated drilling speed and direction or perhaps an expected profile ofthe geology ofthe area being bored so asto enable a comparison between the actual and the predicted geology. Also, selections from a menu of measurements that can be made could be loaded into data storage 22.
An alternative embodiment of the present invention would include a sonde mounted within the bore of a sub by appropriate means, such as spider web brackets. The sonde would include data storage and resistivity sensor electronics with the bore mounted sensor electronics connected to sub mounted sensor antenna means. The operation would be the same as described above with compatible surface equipment being coupled to the sensor antenna meansto transmit instructions and receive data collected from down hole.
The present invention could also be used in recovering data in any instance where data is collected and stored in a sealed container, and it is desirous to maintain the sealed condition ofthe container. For example, recovering flow rate data from a pipeline by the present invention would avoid downtime and possible environmentally damaging spills. Other exampleswould include recovering data concerning activity within a nuclear cell ortemperature/pressure conditions within a container housing hazardous materials.
The above-described apparatus normally operate in the radio frequency range. The present invention could also be used with sonic equipment bysubstitution of appropriate sensors.
The foregoing disclosure and description ofthe invention is illustrative and explanatory thereof, and various changes in the method steps as well as in the details ofthe illustrated apparatus may be made within the scope of the appended claims.
