Description

[0001] DEVICE FOR MEASURING DATA IN DRILL HOLES AND METHOD FOR ITS ASSEMBLY

[0002] The invention relates to a device for measuring data in boreholes with a sensor, a cable section and a protective sheath, wherein a holder is arranged on the protective sheath which is designed and suitable for carrying the device for measuring data in boreholes.

[0003] To measure and record data, such as temperature, at different depths in boreholes, a number of sensors are typically used, arranged along a flexible cable. This sensor array is positioned vertically in the borehole, and the data collected is recorded as a function of depth. The sensor array is enclosed in a protective casing to shield it from water and other environmental factors.

[0004] Such a sensor chain is shown, for example, in the German patent DE 1020 1001 4415 A1 "Device and measuring method for measuring an underground temperature and use of semiconductor sensors". The sensor chain is surrounded by a tube made of a flexible material, e.g., rubber or plastic.

[0005] The document EP 3464812 B1, "Devices and methods for measuring temperature along a borehole using semiconductor elements," discloses a device for use in measuring temperature in a borehole, comprising: a pipe, which is a metallic pipe, containing a plurality of temperature measuring modules provided at positions along the inside of the pipe. Both devices shown here have the disadvantage of being complicated and therefore expensive to manufacture.

[0006] It is therefore an object of the present invention to provide a device for measuring data in boreholes that is easy, quick and therefore inexpensive to mount in a borehole.

[0007] It is also an object of the present invention to provide a method for mounting a device for measuring data in boreholes, with which such a device can be mounted in a borehole simply, quickly and therefore cost-effectively.

[0008] The problem is solved by the device according to the invention for measuring data in boreholes. Advantageous embodiments of the invention are also set out in the dependent claims.

[0009] The device according to the invention for measuring data in boreholes comprises a sensor, a cable section, and a mounting bracket. The sensor is arranged on the cable section. The protective sheath encloses the cable section and the sensor, so that the cable section and the sensor are arranged within the protective sheath. Furthermore, the protective sheath includes a mounting bracket. The cable section comprises a cable strand with one or more conductors to which the sensor is connected. The mounting bracket and / or its attachment to the protective sheath is designed and suitable for supporting the weight of the device for measuring data in boreholes. It is intended that the device for measuring data in boreholes is attached at one end outside or above the borehole, and that the loose end of the device is allowed to hang into the borehole or a pipe arranged in the borehole.A protective sheath has the advantage that the cable and sensor are protected from dirt and water. Attaching the mounting bracket to the protective sheath, in turn, has the advantage that the electronic components, such as the cable, are not subjected to mechanical stress by the bracket or its fastening. In an alternative embodiment of the invention, the device for measuring data in boreholes is designed and suitable for continuous operation. For the purposes of this document, a device for continuous operation is provided in that the elements of the device for measuring data can be arranged in a borehole and / or a protective casing of a borehole and are also designed to be arranged in a borehole and / or a protective casing of a borehole. In an optional embodiment, the device is designed to be waterproof according to protection class IP05, preferably IP06, and particularly preferably IP07.

[0010] In a further development of the invention, the protective sheath is designed to be tubular and / or flexible. A tubular shape of the protective sheath accommodates the elongated shape of the cable run and / or the borehole. The flexible design of the protective sheath ensures simplified handling, since the device, and in particular the cable run arranged within the protective sheath, can be rolled up for transport and only needs to be unrolled to the extent required by the depth of the borehole and / or the measurement project for insertion into a borehole.

[0011] In a further embodiment of the invention, the protective sheath is closed at one end. This has the advantage of preventing the ingress of water or dirt. Depending on the material of the protective sheath, the closure can be achieved by gluing, welding, or other means.

[0012] In a further development according to the invention, the protective casing has, in addition to the closed end, a second end to which the mounting is attached. The mounting and / or its attachment to the protective casing is designed and suitable for supporting the weight of the device for measuring data in boreholes. It is intended that the device for measuring data in boreholes is attached at one end outside or above the borehole, and that the loose end of the device is allowed to hang in the borehole or in a pipe arranged in the borehole. In a further development according to the invention, the mounting has a connecting element that is attached to the protective casing. This connecting element is suitable for attaching the device according to the invention, which is connected to the mounting, outside or above the borehole.

[0013] In a further optional embodiment of the invention, the holder has an engagement element that is designed and suitable for engaging with a pipe or well casing. In an optional embodiment, the engagement element is a hook that can be hooked onto the edge of a well casing. In this document, the terms pipe and well casing are used synonymously.

[0014] In a further embodiment of the invention, the engagement element is designed and suitable for covering a well pipe and / or can be connected to a cover that is designed and suitable for covering a well pipe. This has the advantage that no foreign bodies can enter the well pipe, which in turn could damage the device according to the invention.

[0015] In an optional embodiment of the invention, a cover is arranged at the second end of the protective sheath, which is designed and suitable for closing the protective sheath. This also protects the protective sheath from the unintentional ingress of foreign objects directly into the cable run. In an optional embodiment, the cover has a feedthrough designed and suitable for allowing the cable run to pass through. This ensures proper cable routing without pinching and damaging the cable between the protective sheath and the cover. In a further optional embodiment of the invention, the cover is designed and suitable for covering a pipe inserted into the well. This cover thus seals the well pipe along with the protective sheath. Furthermore, this cover can optionally also serve as a holder for the device.In an optional embodiment of the invention, the protective sheath has an opening at one end for the cable. The cable arranged in the protective sheath can thus be led out of the protective sheath in order to be connected, for example, to a controller and / or evaluation unit.

[0016] In a further embodiment of the invention, the cable section with the sensor is embedded in a filling within the protective sheath. This has the advantage that the cable section and / or the sensor are additionally protected by the filling.

[0017] In an optional embodiment of the invention, the filling is thermally conductive. Using a thermally conductive filling can improve the functionality of the device according to the invention, since, for example, a sensor embedded in air can only detect the ambient temperature outside the casing with difficulty. In an optional further development of the invention, the filling is sand or ceramic. Both types of filling offer protection against mechanical stresses and also exhibit good thermal conductivity.

[0018] In a further embodiment of the invention, the cable section has several sensors. The sensors are arranged at intervals along the cable section. This has the advantage that several parameters, such as pressure and temperature, can be measured with the device according to the invention without having to change the device for measuring data in boreholes. In addition, it is possible to carry out measurements simultaneously at different depths of the borehole.

[0019] In a further embodiment of the invention, the cable length measures at least 3 m, preferably at least 10 m, particularly preferably at least 20 m, and especially preferably at least 50 m or longer, optionally more than 100 m. The advantage of the invention is particularly effective with long cable lengths. The successive sealing of the protective sheath offers significant advantages in the manufacture of the device according to the invention, especially with long cable lengths. If one were to forgo joining the protective sheath along the seams, the cable length and, if applicable, the filling would have to be inserted into the protective sheath along its entire length. The longer the cable length, the more difficult this becomes.For a tightly fitting protective sheath or a filling within the protective sheath, manufacturing is considerably easier if the cable section and / or the filling can be inserted piece by piece into the closed section of the protective sheath, and / or if the protective sheath is to fit tightly around the cable section and / or the sensor.

[0020] In a further embodiment of the invention, the device according to the invention features a seam. The seam is a joining seam along which two edges of the protective sheath are joined to close it. This can involve several different parts of the protective sheath or a single part whose opposite edges are joined. The successive closing of the protective sheath offers significant advantages in the manufacture of the device according to the invention. The cable sections used are several tens of meters long. With a tightly fitting protective sheath or a filling within the protective sheath, manufacturing is considerably simplified if the cable section and / or the filling can be inserted piece by piece into the closed section of the protective sheath and / or if the protective sheath is to fit tightly around the cable section and / or the sensor.A protective sheath that fits tightly around the sensors has the advantage of allowing better heat and / or pressure conduction from the ambient conditions to the sensor.

[0021] In a further embodiment of the invention, the seam is formed by a weld. Welding is a well-known and easily controlled technology for joining different materials. Suitable materials include, for example, natural rubber, synthetic rubbers (e.g., EPDM, NBR, SBR), plastics (e.g., PVC, PUR - polyurethane, PA - polyamide, PE - polyethylene, silicones, Teflon), fiberglass, carbon fiber, or even metals (e.g., stainless steel, aluminum, brass, copper). In another embodiment of the invention, the seam is an adhesive seam. Bonding is a well-known and easily controlled technology for joining different materials. Suitable adhesive materials include all commercially available adhesives, such as organic compounds, elastomers, thermoplastics, emulsions, and thermosets. Examples of thermoset adhesives are epoxy, polyurethane, cyanoacrylate, and acrylic polymers.

[0022] In an advantageous embodiment of the invention, the seam extends along the longitudinal direction of the protective sheath. This has the advantage that the protective sheath can be manufactured in one piece by joining the opposite edges of a rectangular protective sheath section. The joining of the edges can be carried out successively so that the protective sheath can be filled section by section with the cable and / or the filling material.

[0023] In an optional embodiment of the invention, the protective sheath has several seams. Depending on the manufacturing process, it may be necessary to join several parts of the protective sheath together. For example, it is advantageous to join several short hose sections of the protective sheath to form one long protective sheath.

[0024] In a further embodiment of the invention, the seams run parallel. The distance between the parallel seams is 50 cm, preferably 1 m, particularly preferably 2 m, and especially preferably 5 m. This allows the protective sheath to be assembled from small hose sections during manufacturing by welding or gluing the end edges of the hose sections. In an optional embodiment of the invention, the hose sections are at least 50 cm long.

[0025] The problem is further solved by means of the inventive method for mounting a device for measuring data in boreholes on a borehole. Advantageous embodiments of the invention are set out in the dependent claims. The inventive method for mounting a device for measuring data in boreholes on a borehole comprises the process steps of inserting a cable section equipped with sensors into a borehole and engaging a bracket attached to the device with a pipe inserted into the borehole. The bracket and / or its attachment to the inventive device for measuring data in boreholes is designed and suitable for supporting the weight of the device for measuring data in boreholes.The device for measuring data in boreholes is intended to be attached at one end outside or above the borehole by means of the bracket, and the loose end of the device is to be suspended in the borehole or a pipe arranged in the borehole by means of the cable run.

[0026] In an alternative embodiment of the invention, the device for measuring data in boreholes is mounted in such a way that it can be operated continuously after installation. For the purposes of this document, a device for continuous operation is provided in that the elements of the device for measuring data can be arranged in a borehole and / or a protective casing of a borehole and are also designed to be arranged in a borehole and / or a protective casing of a borehole. In an optional embodiment, the device according to the invention is mounted in such a way that it is watertight according to protection class IP05, preferably IP06, particularly preferably IP07, and / or can be operated in this manner.

[0027] In a further development of the invention, the device has a protective sheath enclosing the cable run and the sensors. This has the advantage that the electronic components of the device according to the invention are protected from dirt and water. In an optional embodiment of the invention, a mounting bracket is attached to the protective sheath. A protective sheath has the advantage that the cable run and the sensor are protected from dirt and water. Attaching the mounting bracket to the protective sheath, in turn, has the advantage that the electronic components, such as the cable run, are not subjected to mechanical stress by the mounting bracket or its attachment. In an embodiment of the invention, the mounting bracket comprises a connecting element and / or an engagement element.The engagement element is brought into engagement with a part of the borehole or elements of the borehole, such as the well pipe, a protective pipe, or the concrete base, in order to support the weight of the elements of the device according to the invention that are inserted into the borehole.

[0028] Optionally, the connecting element is attached to the protective sheath. This can be, for example, a welded sleeve or a PE fitting. In another optional embodiment, the connecting element is connected to the engagement element.

[0029] In an optional embodiment, the engagement element engages with the well pipe or another external element of the well. Optionally, the engagement element is a hook that is hooked onto the edge of a well pipe.

[0030] In a further embodiment of the invention, the engagement element is placed on a well pipe. In a further development, the engagement element acts as a cover, partially or completely covering the well pipe. This has the advantage that no foreign objects can enter the well pipe, which in turn could damage the device according to the invention.

[0031] In another embodiment, the engagement element is designed or selected to match the intended pipe. Since most pipes have standard dimensions, the engagement element can be adapted to these various standard dimensions. During installation, it is then only necessary to select and / or install the engagement element corresponding to the pipe diameter, according to the specific conditions.

[0032] In an alternative embodiment of the invention, the cable is connected to a communication unit for receiving sensor signals. The communication unit enables the transfer of sensor signals and / or data acquired during operation of the device according to the invention to an evaluation unit.

[0033] In a further embodiment of the invention, the length of the cable and / or the protective sheath is adapted to the intended measuring depth in the borehole. This has the advantage that the device according to the invention can be installed for continuous operation in a borehole for measuring data. This allows the protective sheath and / or the cable to be fully inserted into the borehole and / or a pipe inserted into the borehole and remain there for continuous operation. Currently, this is not possible with existing measuring methods, as the cable lengths are designed for maximum lengths to be usable in as many boreholes as possible. Customizing the device for specific application locations makes it possible to perform measurements in continuous operation and thus measure dynamic changes in environmental parameters within the boreholes.

[0034] In a further embodiment of the invention, the bracket and / or its attachment to the protective casing is designed and suitable for supporting the device for measuring data in boreholes. It is provided that the device for measuring data in boreholes is attached at one end outside or above the borehole, and that the loose end of the device is allowed to hang into the borehole or a pipe arranged in the borehole.
