Abstract

A method and apparatus for obtaining measurements from a well bore during discharge operations is provided. A drill aid is attached to the drill pipeline coupled adjacent to or as close as possible to the drill before starting normal drilling operations. Before starting the unloading operations, a registration tool is attached inside the drill aid. The coupling of the registration tool inside the drill aid opens a window mechanism that allows the detectors of the logging tool to obtain data from the hole in the well. As discharge operations are conducted, the registration tool obtains data over the entire length of the pore hole.

Description

DATA RECORDING OR MEASUREMENT DURING DISCHARGE The present invention relates to a method and device for providing a high resolution image of a well hole obtained while discharging drill pipes from a well hole. The apparatus and the method provide a record of the well bore, including a profile of the variations in formation, chemical and mechanical condition. The method and the apparatus *** "You can get this information while drilling holes in vertical, inclined or horizontal wells.

BACKGROUND OF THE INVENTION Information concerning the condition of an orifice drill is important for the success of the drilling process from a quality control and from the point of view of planning. The information, which comprises many parameters, can be used to warn engineers of changes in the well profile and the stability of the operation. For example, drill hole diameters must be carefully controlled during drilling as they can affect the performance of the lower orifice assemblies used in directional drilling, restrict the drilling fluid's ability to remove cuts from the wellbore and may limit the success of the cementation of production tubing in the site prior to the commercial operation of the well. In addition, drill hole information is used to determine the types of formation (lithology) encountered as an indication of the potential of the well to produce hydrocarbons. There are in practice many other applications that use well hole information in a timely manner. To obtain information about the lower orifice conditions, it is often necessary to suspend the drilling process at specified depths, remove (remove) the line of drill pipe coupled from the bore hole and lower a detection tool with a collection of detectors at the end of a cable (a steel cable telemetry system) inside the well. Then the detection tool is slowly removed and the data of the tool is transmitted to the surface to the connection cable. Information about the condition of the well is recorded (recorded in the registry) and subsequently analyzed. This process is known as a steel cable log and is capable of producing a tremendous amount of information that engineers can use to construct a physical representation of the well's condition along its entire length. This type of monitoring has two inherent problems: (1) it depends on the severity for the instrument to descend and, therefore, if the orifice is inclined or has similar stages to seats on the external surface of the drill hole, the instrument can be hung and, (2) does not occur during normal drilling or unloading operations and, therefore, does not provide the driller with current or real-time information on the status of the drilling. Finally, because drilling operations must be suspended, this method is time consuming for well drilling operations and therefore is expensive to undertake. A second logging technique while drilling (LWD) involves the placement of a specialized drill collar that contains detection devices close to the drill bit. Since it is positioned on the coupled drill pipe line, it is capable of accessing horizontal sections of the bore hole and is not susceptible to hanging. This technique measures the information to the surface by means of acoustic impulses transmitted through the drilling fluid. This technique has been limited in a number of ways: First, it has been limited by the types of drilling fluids that can provide effective acoustic coupling, often limited to drilling fluids such as water, oil or emulsions. In addition, since this technique obtains data while the drill is turning (ie, a noisy and vibrating environment), it typically has a very slow data transmission speed (1 bit per second) that requires substantial processing of data. computer to compensate for the rotation of the drill bit and artifact errors.

- In addition, LWD only collects the data immediately behind the drill bit and does not obtain data from other regions of the drill hole. Therefore, if a leak occurs in the upper part of the hole, this technique will not detect it. Therefore it becomes It is necessary to back up the LWD data with the steel cable registration data. Accordingly, this technique, in addition to requiring expensive LWD equipment, also requires the time-consuming technique of recording steel cable with additional steel cable recording equipment. 10 A variety of techniques and methods have been used to transfer the accumulated data from the downhole detectors in the LWD application. A wireless technique transmits the information to the surface using acoustic signaling through the drilling fluid (mud) as it is called mud impulse. The type of telemetry, described in Canadian Patent 1,098,202, is restricted to certain types of drilling fluid exhibiting reasonably low loss transmission. However, the transmission speeds are slow (in the order of one bit per second) due to restricted bandwidth in the detectors and the attenuation constants of the medium. Data compression is used to reduce the number of bits transmitted in an effort to improve system performance although this is still fundamentally restricted. Efforts to improve the telemetry trajectory by using the coupled drill pipe line J > "U have only proven to be marginally successful, Canadian patent 1,098,202 and US patents 4,139,836 and 4,320,473 have described this matter in depth although the technique has not gained support in the drilling industry.5 An additional reference of the above interest is EP, A, 0 121 329 which describes a lower orifice tool that forms a component of a coupled drill pipe line.This device is provided with a number of ports that allow a sensing tool to obtain data from a location fixed inside the hole hole.

DESCRIPTION OF THE PREFERRED MODALITY A typical drilling rig 10 is shown in Figure 1. The drilling rig 10 is provided with a drilling rig 12 on a drilling platform 14. During normal drilling operations, a drilling rig line coupled 16 with a drill bit 18 drills hole orifice hole 20 in a conventional manner. During drilling, the circulation head 22 maintains a flow of drilling fluid within the bore hole 20 to effect the removal of debris and maintain lubrication. As drill hole 20 is advanced, additional drill pipes 24 are removed from the grid 26 and attached to the coupled drill pipe line 16. The cycling of the drill pipes 24 in and out of the drill hole 20 is required on a regular basis for the reasons , among others, to replace the worn bits, to adjust / alter / change the types or locations of the pipes 24 in the coupled drill pipe line 16 or, simply, to remove the pipes 24 from the hole 20. During this cycle, the drill pipes 24 removed from the drill hole 20 in sections ranging from approximately 27.36 meters to as small as 9.12 meters depending on the type of drilling equipment 10 employed. Those sections of drill pipe 24, called "supports" are removed at a regular scale and speed and continuously during the interval covering their length. As each support 24 is removed from the well, the movement of the pipe is suspended while the support is decoupled / separated from the coupled drill pipe line (which consists of pipe that is still to be removed from the well) and placed in the derrick 12, by a process known as "forced". During this discharge cycle, a series of cable hooks and "bales" (not shown) continuously move from the floor 28 of the rig 10 (which is a working platform set at approximately 9.12 to 1.2.2 meters above the level). of the floor) where the bales are hooked on the drill pipe 24, up to the upper part of the drilling tower 12 (15. 2 to 30.4 meters above the floor 28) where the operator of the drill rig releases the bullets (after making sure that the uncoupled base of the support 24 has been located on the perforation floor 28 away from the upper part of the exposed upper part 30 of the coupled perforation line 16) before forcing the support 24. The bullets are then returned to the 28th floor where the cycle continues, a total cycle time of approximately 3-5 minutes depending on the length of the support. With reference to Figures 1-5, the record measurements according to the invention can be made at the time of normal discharge operations with the drilling auxiliary 34 and the registration tool 36. Before the start of operations A drilling auxiliary is attached to and forms part of the coupled drill pipe line 16 immediately adjacent or as close as possible to the drill 18. The drill aid 34 will typically be a specialized section of the drill pipe 24 with window channels 38 in the wall of the drill pipe 24 and the bore hole 20 as shown schematically in Figure 2 and Figure 4. Alternatively, the window channels 38 of the drilling aid can be represented as cross sections. thin wall of the drill pipe 24 sufficiently thin to allow access to the detectors of the registration tool or 36 to the well hole 20 as shown in Figures 3, 3a, 3b and 3c. In the particular embodiment of the punching aid 34 and the assembly shown in Figures 3, 3a, 3b and 3c, the punching aid 34 comprises a grounding section 80, an upper section 82, a threaded seal 84 and a shoe. 86. The registration tool 36 is shown for coupling within the assembled drill auxiliary 34 with the ground shoe 86. The ground section 80 has a threaded section 88 for attachment of a drill 18 or other line section of coupled drill pipe 16. The upper portion of the grounding section 80 is provided with a threaded section 90 for receiving engageable threads 92 of the upper section 82. Similarly the upper portion of the upper section 82 is provided with with threads 94 for coupling with a line section of coupled drill pipe 16. Accordingly, the grounding section 80 and the upper section 82 are bolted together in connection. The threaded seal 84 is seated between the two sections to seal against fluid loss through the threaded sections 90 and 92. The adjustable shoe or register tool seating device 86, located in the lower region of the section of grounding 86, allows the settlement and * - alignment of the registration tool 36 within the auxiliary perforation 34. The window channels 38 may be provided with a window mechanism 40, hydraulically actuated in response to a registration tool 36 that sits within the piercing aid 36. The window mechanism 40 is provided with windows 42 that are rotated to open the window channels 38 to allow the detectors of the registration tool 36 to enter the bore hole 20. The hydraulic drive may be provided through pressure tubes 44 (Figure 2). In a modality of the window mechanism as shown in Figure 4, the window mechanism comprises a sliding sleeve 100 on the supports 102. The sleeve 100 has the locking mechanism 104 for locking the registration tool 36 on the sleeve 100. The locking mechanism of the sleeve 106 is provided for locking the sleeve 100 in the closed position.

In operation, the registration tool 36 enters the piercing aid 34. The ground shoe section 108 of the registration tool 36 engages and latches with the locking mechanism. 104. As the registration tool 36 is driven into the drilling auxiliary 34, the sleeve 100 is driven along the grounding section 80, decoupling the sleeve locking mechanism 106. The sleeve 100 slides along the length of the sleeve. the grounding section 80 until the front edge 100 of the sleeve 100 engages against the surface 1 12, thereby removing the sleeve 100 from the window 38. The window 38 is closed by removing the registration tool 36 from the drilling aid 34. As the registration tool 36 is removed, the sleeve 100 slides to close the window 38. As the sleeve 100 engages against the edge 1 14, the locking mechanism 106 is re-engaged to lock the sleeve 100 in the closed position. The removal of the registration tool 36 decouples the locking mechanism 104 from the registration tool 36. It is understood that other window mechanisms can be designed on the auxiliary drill 34 according to the invention. The registration tool is provided with a series of detectors that include, but are not limited to, an address detector 50, gamma ray detector 52 and acoustic pulse generators and receivers 54 shown schematically in Figure 5. The direction detector 50 can be used to determine the relative direction of movement of the coupled drill pipe line 16 at a given time, that is, either the top hole or the bottom hole. The gamma ray detector 52 can detect natural gamma-ray emissions within the rock formation for the characterization of the lithology and the acoustic impulse generators and receivers can be used to detect the diameter of the drill hole 20 and the lithology and the porosity. The detectors are connected to the computer 56 which receives power from the batteries 58. The computer 56 can activate the associated detectors at a given time, t, and subsequently receive and store data received from the detectors. Alternatively, the detectors may be activated in response to a coupled line drilling line motion detector 50. Other detectors or transducers may include but not be limited to devices for motion measurement of the coupled drilling line, emissions of gamma rays, pressure, temperature, resistivity, natural potential (DC voltage) and the direction of the drill hole. The detectors can be emission and reception devices or reception-only devices. In the acquisition of data from the bore hole 20, the following procedures are conducted to obtain a record of the physical characteristics of the bore hole correlated to the depth of the bore hole (Figure 6).

At the time of starting normal drilling operations, the drilling aid 34 is attached to and forms part of the coupled drill pipe line 16 immediately behind or as close as possible to the drill 18. Normal drilling operations are conducted until a well hole depth is obtained 20, d, and discharge operations are required to bring the drill 18 to the surface. The drilling operations are suspended and the circulation head 22 is removed from the coupled drill pipe line 16 and raised from the joint 30. The registration tool 36 is prepared for insertion into the coupled drill pipe line 16. and verified by the surface computer 60 connected to the registration tool 36 via the serial link 62. The surface computer 60 checks the state of charge of the batteries 58, the detector status, synchronizes the clock clocks of the included computer 56 with those of the surface computer 60, and in one embodiment, sets a time, t, for the initiation of data collection. After the surface checks and synchronization are completed, the registration tool 36 can be seated in the drilling auxiliary 34 by two different methods. In the first embodiment, the registration tool is lowered into the perforated drill pipe line 16 by the cable 64 and the pulley 66 attached to the cable connection and the release mechanism 68 on the upper orifice end of the tool. 36. The cable connection and the release mechanism 68 are for lowering the registration tool 36 within the coupled drill pipe line 16 and for releasing the wire 64 from the registration tool 36. The lowering of the Downstream registration tool of the coupled drill pipe line 16 may require drill rods (not shown) to provide added weight to the registration tool 36. In another embodiment, the registration tool is placed in the coupled drill pipe line 16 and the circulation head 22 is reattached to the coupled drill pipe line 16. A drilling fluid circulation is started until the logging tool 36 reaches its grounding point on the ground. the drilling auxiliary 34. Through the movement of the registration tool 36 within the position »- * by pumping drilling fluid, it is possible for the registration tool to access horizontal regions on the coupled drill pipe line 16 as shown in Figure 1. The operator of the circulation head will detect an increase in the pressure when the recording tool reaches its grounding point inside the drilling auxiliary 34 and the registration tool connecting device 48 sits within the drilling auxiliary connection device 46. In the auxiliary mode of the auxiliary. perforation 34 provided with windows hydraulically actuated 48, the pressure build-up, which acts through the pressure tubes 44, will actuate the window mechanism 40, so that the windows 42 provide access for the log tool detectors to the well bore 20. In the sliding mechanism and hydraulic modes of the window mechanism, the surface operator will detect a decrease in pressure that signals that the windows are open and that unloading operations can begin by removing the lines of coupled drill pipe. from the bore hole 20 in a conventional manner. The signal for data collection may be a fixed time established between the surface computer 62 and the included computer 56 or may be signaled by the directional detector 50 driven by the initial upper orifice movement of the pipe line. perforation coupled 16 as discharge operations begin. In any case, as the coupled drill pipe line 16 moves towards the upper hole, the data from the detectors of the recording tool will be stored in the included computer 56 as a function of time. At the same time, the surface computer 60 monitors the depth of the registration tool 36 by recording the amount of pipe removed from the hole hole 20 at any time, t, and subtracting this value from the absolute depth of the hole in the hole. drill, d. This screening can be done in various ways as will be understood by those skilled in the art.

After the entire line of coupled drill pipe 16 has been removed from the drill hole 20, the logging tool can be retrieved from the drilling aid 34 and affixed back to the surface computer 60 5 via the serial link 62. The data stored within the included computer 56 to which the lower load is made to the surface computer 60 and is coupled with the depth of the coupled drill pipe line 16 as a function of time to provide a log of the bore hole. .10 Alternatively, if the drill pipe line coupled 16 does not need to be removed although it is "desirable to remove the registration tool 36 for the lower loading data, the registration tool can be retrieved from the loading aid 34 by an" overshoot "device (not shown), well known to those skilled in the art. > • The conjunction of data on the surface will combine the lower load data against the time readings from the registration tool 36 with the depth against the time data from the surface acquisition system to provide the data from desired bottom load against the depth data.
