PERCEPTION OF TRAINING DATA WITH REMOTE SENSORS DISPLAYED DURANT? THE WELL DRILLING.

REFERENCE TO RELATED REQUESTS This application claims the priority of provisional application Serial No. 60 / 048,254, filed on June 2, 1997, and incorporates such provisional request by reference herein.

BACKGROUND OF THE INVENTION Field of the Invention This invention relates generally to the drilling of deep wells. such as for the production of petroleum products and refers more specifically to the acquisition of subsupressural formation data such as formation pressure, formation permeability and the like, while well drilling operations are in progress.

Description of the Related Technique In the petroleum well description services, a part of the conventional formation evaluation parameters is related to the deposit pressure and the permeability of the deposit rock. Current operations obtain these parameters either through wireline logging through a "training tester" tool or through drilling rod tests, both types of measurements are available in "open hole" applications or "housed hole", and require a supplementary "trip", ie, remove the drill string from the well borehole, run a formation tester towards the well borehole to acquire the training data and, after removing the Training tester, run the drill string again towards the well drilling for additional drilling. Due to the reason that "fixing in the well" in this way uses significant amounts of expensive equipment time, it is typically done under circumstances where training data is absolutely needed or done when the string trip is made. Drilling for a drill bit change or due to other reasons. During well drilling activities, the availability of deposit formation data on a "real time" basis is a valuable asset. The real-time formation pressure obtained while drilling will allow a drilling engineer or driller to make decisions regarding changes in drilling mud weight and composition as well as penetration parameters in a much more anticipated time and this promote the safety aspects of drilling. The availability of real-time deposit formation data is also desirable to allow precision control of drill bit weight in relation to changes in formation pressure and changes in permeability, so that the drilling operation can carried out at its maximum efficiency. Therefore, it is desirable to provide a method and apparatus for drilling wells that allow the acquisition of various data d? formation from a sub-surface area of interest, while the drill string with its drill collars, drill bit and other drilling components are present within the well bore, thereby eliminating or minimizing the need for shoot the trip of the well drilling rig for the sole purpose of running training testers towards well drilling for identification of these training parameters. It would also be desirable to provide a method and apparatus for drilling wells that have the ability to acquire parameters of formation data, such as pressure, temperature and permeability, etc., while well drilling is in progress and doing so in relation to methods known for well drilling. To address these long-felt needs in the industry, a principal object of the present invention is to provide a novel method and apparatus for acquiring data from subsurface formation in relation to well drilling operations d? sounding without needing to shoot the drilling string from the drilling d? water well. Another object of the present invention provides a novel method and apparatus for acquiring data of subsupseural formation during operations d? drilling. A still further object of the present invention TS to provide a novel method and apparatus for acquiring subsurface formation data while drilling a well d? Probing is in progress. Another object of the present invention is to provide a novel method and apparatus for acquiring subsurface formation data by placing a remote data sensor / transmitter within a subsupface formation adjacent to a sounding well., selectively activate the remote data sensor to perceive, record and transmit the training data, and selectively receive the data d? training transmitted through the drilling rod system for display to drilling personnel. A still further object of the present invention is to provide such novel method and apparatus by means of one or more remote "intelligent" training data sensors, which allows the transmission of training data on a substantially real-time basis to a receiver. data in a drill collar or probe that is a component of the drill string and has the ability to transmit the data received through the drill string to surface equipment for display to drill staff.

COMPENDIUM OF THE INVENTION The objects described above, as well as various objects and advantages, are achieved by a method and apparatus that contemplate drilling a borehole with a drill string having a drill collar with a drill bit connected to the borehole. same. the collar d? drilling has a training data receiver system and one or more remote data sensors that have the ability to perceive and record training data such as temperature, pressure, permeability, etc., and to transmit signals that represent the perceived data. When the collar d? perforation is adjacent to a selected subsurface formation such as a deposit formation, the apparatus d? Drill collar is activated to place at least one data sensor within the subsurface formation outwardly beyond the drill hole for the perception and transmission of training data in order. The data signals d? formation transmitted by the ST data sensor are received by the receiver circuit on the drill collar and are transmitted further through the string d? drilling to surface equipment such as drilling console where the training data is displayed. Monitoring the changes in the training data perceived and exhibited, the staff d? Drilling is able to quickly and efficiently adjust conditions in the bottom of the well such as drilling fluid weight and composition, drill bit weight, and other variables, to control the safety and efficiency of the drilling operation. The intelligent data sensor can be placed within the formation of interest by any appropriate means. For example, a hydraulically activated ramp can drive the sensor from the collar d? drilling towards the formation with sufficient hydraulic force so that the sensor penetrates the formation in a sufficient depth to perceive training data. In the alternative. the apparatus in the drill collar can be extended to drill outwards and laterally towards the formation, with the sensor being placed inside the lateral perforation by means of a sensor actuator, as an additional alternative, a propeller activated system on the drill collar can be activated to turn on the sensor with sufficient force to penetrate towards the formation laterally beyond the well d? probe. The sensor is properly encapsulated to withstand the damage during its lateral installation into the formation, whatever the method may be. training placement. To enable its acquisition and transmission of training data, the sensor is provided with an electrical power system, or it can be a system d? battery or an inductive AC power that draws from an energy cartridge on the drill collar. A micro-chip in the sensor assembly will allow the sensor circuit to perform data storage, handle the measurement processing for the selected training parameter or parameters and transmit the recorded data to the receiving circuit of a training data cartridge on the Drilling arin. The training data signals are processed by the training data circuit in the energy cartridge to a shape that can be sent to the surface through d? the drill string or by any other appropriate data transmission system, so that the data signals can be displayed to, and supervised by, the drilling personnel? well, typically in the equipment drilling console d? drilling. The data changes at the bottom of the well during the drilling procedure will be known, either on a d basis? Real time or on a frequency that is selected by the drilling personnel, thus allowing the drilling operation to be done especially for the training parameters that exist at any point in time.

However, it will be noted that the appended drawings illustrate only a typical embodiment of this invention, and therefore, should not be considered limiting of its scope, since the invention may admit other equally effective modalities. In the drawings: Figure 1 is a diagram of a drill collar placed in a borehole and equipped with a section d? probe d? sensor / data transmitter in accordance with the present invention; Figure 2 is a schematic illustration of section d? sensor probe / data transmitter of a drill collar that has a hydraulically activated system to forcefully insert a sensor / transmitter d? remote formation data from the borehole to a selected subsurface formation; Figure 3 is a diagram schematically depicting a drill collar having an energy cartridge therein that ST provides with an electronic circuit for receiving formation data signals from a remote formation data sensor / transmitter; Figure 4 is an electronic block diagram schematically showing a remote sensor that is positioned within a subsurface formation selected from the drilling well that is being drilled and that senses one or more data parameters d? formation such as pressure, temperature, and rock permeability, place the data in memory and. as instructed, transmits the stored data to the cartridge circuit d? energy d? l drill collar; Figure 5 is a diagram d? electronic block that schematically illustrates the receiver coil circuit of the sensor / transmitter d? remote data; and Figure 6 is a timing diagram d? transmission that shows modulation of pulse duration.

DESCRIPTION OF THE PREFERRED MODALITIES Referring now to the drawings and first to Figures 1-3, a collar d? perforating that TS a component of a drill string for drilling a sounding well ST generally shows at 10 and represents the preferred embodiment of the invention. The drill collar is provided with a probe section 12 having a cartridge 14 d? energy that incorporates the transmitter / receiver circuit d? Figure 3. The drill collar 10 is also provided with a pressure gauge 16 having its pressure sensor 18 exposed to the pressure of the borehole through a passage 20 of the drill collar. The pressure calibrator senses the ambient pressure at the depth of a selected subsurface formation and is used to verify the calibration d? pressure of remote sensors. The electronic signals that represent the well pressure d? environmental sounding S? transmit through the pressure gauge 16 to the cartridge circuit 14 d? energy that. In turn, it achieves the pressure calibration of the remote sensor that is being deployed at that particular depth of the well d? probe. The drill collar 10 is also provided with one or more sensor receptacles 22 each containing a remote sensor 24 to be placed inside d? a selected subsurface formation of interest that is intersected by the drilling well that is being drilled. The remote sensors 24 are "intelligent" encapsulated sensors that ST move from the drill collar to a position within the formation surrounding the borehole to perceive formation parameters such as pressure, temperature, rock permeability, porosity, conductivity and dielectric constant, among others. The sensors are appropriately encapsulated in a sensor housing of sufficient structural integrity to withstand the damage during the movement of the collar d? perforation towards laterally embedded relationship with the subsurface formation surrounding the well d? probe. Those experienced in the field will appreciate that such lateral incrustation movement need not be perpendicular to the borehole, but can be achieved through d? numerous angles of attack towards the desired training position. The deployment of the sensor can be achieved by using one or a combination of the following: (1) drill into the borehole wall and place the sensor into the formation; (2) pierce / press the encapsulated sensors towards the formation with a hydraulic press or mechanical penetration assembly; or (3) trigger the ß-encapsulated sensors towards the formation using propellant charges. As shown in Figure 2, a hydraulically activated ram 30 is employed to deploy the sensor 24 and to cause its penetration into the subsupply formation to a sufficient position out of the borehole which senses the selected parameters of the formation. For deployment of the sensor, the drill collar ST provides with an internal cylindrical bore 26 inside which a piston element 28 is placed having a ram 30 which is disposed in drive relation with the remote, intelligent, encapsulated sensor 24 . The piston 28 is exposed to hydraulic pressure which is communicated to a piston chamber 32 from a hydraulic system 34 through a hydraulic supply passage 36. The hydraulic system is selectively activated by the power cartridge 14 so that the remote sensor can be calibrated with respect to the pressure of the environmental sounding well in the forming depth, as described above, and then can be moved from the receptacle 22 towards the formation beyond the well wall d? sounding so that the pressure parameters of the formation are free of the effects of the well d? sounding Referring now to Figure 3, the power cartridge 14 of the drill collar 10 incorporates at least one transmitter / receiver coil 38 having a drive 40 d? Transmitter energy in the form d? an energy amplifier having its frequency F determined by an oscillator 42. The drill collar probe section is also provided with a tuned receiver amplifier 43 which ST adjusts to receive signals at a frequency 2F to be transmitted to the probe section of the piercing collar by means of a remote sensor of the "small bullet" type as will be explained later. With reference to Figure 4, the electronic circuit of the "intelligent sensor" ST shown by a block diagram generally at 44 T includes at least one transmitter / receiver coil 46, or RF antenna, with the receiver thereof providing an output 50 from a detector 48 to a controller circuit 52. The controller circuit is provided with one of its control outputs 54 being supplied to a pressure calibrator 56 so that the calibrator output signals will be conducted to an analog-to-digital converter ("ADC") / memory 58 that receives the signals. signals from the pressure gauge through a conductor 62 and also receives control signals from the controller circuit 52 through d? a conductor 64. A battery 66 is provided within the remote sensor circuit 44 and is coupled to the various sensor circuit components by the power conductors 68, 70 and 72. A memory outlet 74 of the circuit 58 d? ADC / ST memory feeds a receiver coil control circuit 76. The receiver coil control circuit 76 functions as a driver circuit through the lead 78 so that the transmitter / receiver coil 46 transmits the data to the probe 12. Referring now to Figure 5, a low threshold diode 80 is connected through coil control circuit 76 Rx. Under normal conditions, and especially in the sleeping or "sleep" mode, the electronic switch 82 is open, minimizing the power consumption. When the receiver coil control circuit 76 is activated by the electromagnetic field transmitted from the drill collar, a voltage and current is induced in the receiver coil control circuit. At this point, however, diode 80 will allow current to flow in only one direction. This lack of linearity changes the fundamental frequency F of the induced current shown at 84 in Figure 6 to a current having the fundamental frequency 2F, that is, twice the frequency of the electromagnetic wave 84 as shown at 86. Throughout the complete transmission sequence, the transmitter / receiver coil 38, shown in Figure 3, is also used as a receiver and is connects to a receiver amplifier 43 which is tuned to the frequency 2F. when the amplitude of the received signal is at a maximum, the remote sensor 24 is placed in close proximity for optimum transmission between the drill collar and the remote sensor.

OPERATION Assuming that the intelligent remote sensor, or "smart bullet" as it is also called, is in place within the training that ST will monitor, the sequence in which the transmission and acquisition d? Electronic function in conjunction with the drilling operations is as follows: The drill collar with its acquisition sensors is placed in close proximity to the remote sensor 24. An electromagnetic wave at a frequency F. as shown at 84 in FIG. 6, is transmitted from the transiting coil / r? C? Pter of the drill collar to "connect" the remote sensor, also referred to as the target, and to induce the sensor to send back an encoded identification signal. The electromagnetic wave initiates the electronics of the remote sensor to go to the acquisition and transmission mode, and the data d? Pressure and other data representing the selected training parameters, as well as the sensor identification code, are obtained at the remote sensor level. The presence of the target, ie the remote sensor, is detected by the reflected wave scattered again from the target at a frequency of 2F as ST shows at 86 in the diagram d? timing of transmission of figure 6. At the same time, the caliper data d? pressure (pressure and temperature) and other selected training parameters are acquired and the electronics of the remote sensor convert the data into one or more digital signals in series. This signal or digital signals, as the case may be, are transmitted from the remote sensor again to the drill collar via the transmitter / receiver coil 46. This is achieved by synchronizing and coding each individual data bit in a specific time sequence during which the scattered frequency will be switched between F and 2F. The data acquisition and transmission is terminated after the pressure and temperature readings have been obtained and successfully transmitted to the circuit on the drill collar 10. Whenever the above sequence is started, transmitter / receiver coil 38 placed inside the collar d? perforation or the probe section of the drill collar ST active by the power supply of the transmitter or amplifier 40. The electromagnetic wave is transmitted from the drill collar to a frequency F determined by the oscillator 42, as indicated in the diagram of the timing of figure 6 at 84. The frequency F can be selected within the range of 100 Khz to 500 MHz. As soon as the target is within the area of influence of the collar transmitter, the receiver coil 46 placed inside the The intelligent bullet will again radiate an electromagnetic wave at twice the original frequency by means of the receiver coil control circuit 76 and the transmitter / receiver coil 46. In contrast to current operations, the present invention makes available pressure data and other formation parameters while drilling, and as such, it allows well for the drilling personnel to make decisions related to the composition of drilling and weight. of the drilling mud as well as other parameters at a much more anticipated time in the drilling process without needing to fire the drill string for the purpose of running a training tester instrument. The present invention requires very little time to perform the measurements d? Actual training, once ST deploys a remote sensor, data can be obtained while drilling, a feature that is not possible in accordance with well-known well drilling techniques. The time-deent pressure monitoring of trated wellbore formations can also be achieved as long as the pressure data of the pressure sensor 18 is available. This particularity des, of course, on the communication link between the transmitter / receiver circuit inside the energy cartridge of the drill collar and any smart remote sensors deployed. The output of the remote sensor can also be read with wire line dia- gram tools during conventional logging operations. This particularity of the invention makes it possible to vary the data conditions of the subsurface formation that are going to be acquired by means of the electronic ones of the tools of diagraphy in addition to the data of formation of real time that can now be obtained from the formation while it is drilled. Placing the remote smart sensors 24 beyond the immediate borehole environment, at least in the initial data acquisition period there will be no effects of the borehole on the pressure measurements taken. Since no liquid movement is necessary to obtain formation pressures with in situ sensors, it will be possible to measure formation pressure on non-permeable rocks. Those skilled in the art will appreciate that the present invention is equally adaptable for the measurement of various formation parameters - such as permeability, conductivity, dielectric constant, rock resistance, and others, and is not limited to pressure measurement d? training. Additionally, it is contemplated by and within the scope of the present invention that the remote sensors, once deployed, can provide a source d? data d? training for a substantial period of time. For this purpose, TS requires that the positions of the respective sensors be identifiable. In this way, in one modality, the remote sensors will contain radioactive "letter cards" that are identifiable by means of a gamma-ray perception tool or probe together with a gyroscopic device in a string d? tool that improves the placement and individual spatial identification of each sensor deployed in the training. In view of the foregoing, it is evident that the present invention is well adapted to achieve all the objects and features set forth above, together with other objects and features that are inherent in the apparatus described herein. As will be readily apparent to those skilled in the art, the present invention can easily be produced in other specific forms without abandoning its spirit and essential characteristics. The present modality, therefore, should be considered as merely illustrative and not restrictive. The scope of the invention is indicated by the following claims rather than by the foregoing description, and all changes that fall within the meaning and scope of equivalence of the claims, therefore, are intended to be embraced herein.
