Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1 schematically shows the structure of a near-bit data transmission device (hereinafter simply referred to as "device") 100 according to an embodiment of the present invention. As shown in fig. 1 and 2, the apparatus 100 includes a data acquisition mechanism 140, a data transmission mechanism 130, a data reception mechanism 170, and a data processing mechanism 180. The data acquisition mechanism 140 is disposed near the drill bit so as to be operable to acquire geological information, drilling operation-related information, etc., near the drill bit and convert the information into corresponding data. The data transmission mechanism 130 receives data from the data acquisition mechanism 140 and transmits the data in the form of sound waves. The data transmission mechanism 130 is still disposed close to the drill bit. The data receiving mechanism 170 is oriented away from the drill bit in the direction of the surface and is capable of receiving data in the form of sound waves emitted by the data transmitting mechanism 130. The data processing mechanism 180 receives data from the data receiving mechanism 170, processes the data, and transmits the data to the surface.
As shown in fig. 1 and 2, a boss 111 may be provided radially outward of the eye at the lower end of the substantially cylindrical power drill 110. For example, a plurality of protrusions 111 spaced apart from each other in the circumferential direction may be provided. Fig. 2 shows an embodiment of 3 protrusions 111 spaced apart from each other in the circumferential direction. However, it should be understood that 1, 2, 4, 5, or more protrusions 111 may be provided as desired. The data acquisition mechanism 140 and the data transmission mechanism 130 may be provided in the above-described boss portion 111. For example, the data acquisition mechanism 140 and the data transmission mechanism 130 may be disposed in different (preferably adjacent) bosses 111.
In a preferred embodiment, the protrusion 111 may be formed by a centralizer of the motor 110 itself. Thus, the device 100 of the present application can be incorporated by light machining of an existing standardized power drill 110.
The data acquisition mechanism 140 and the data transmission mechanism 130 may be connected together by a data transmission cable (not shown). To this end, as shown in fig. 2, a first bore section 162 may be formed on the motor-driven drill 110, which extends from the location of the data acquisition device 140 toward the data transmission device 130. The first bore segment 162 preferably does not extend directly toward the data transmission mechanism 130, but rather has a certain angle of deflection radially outward. Correspondingly, a second bore segment 161 is also formed on the motor drill 110, which extends from the data transmission device 130 to the data acquisition device 140. The second bore segment 161 preferably does not extend directly toward the data acquisition mechanism 140, but rather has a radially outwardly biased angle. The first bore section 162 and the second bore section 161 are in communication with each other, thereby allowing a data transmission cable to pass through the first bore section 162 and the second bore section 161 to connect the data acquisition mechanism 140 and the data transmission mechanism 130 together. Preferably, at the portion where first bore section 162 communicates with second bore section 161, first bore section 162 and second bore section 161 intersect at an obtuse angle. More preferably, the first and second bore sections 162 and 161 communicate smoothly and relatively smoothly at a portion where the first and second bore sections 162 and 161 communicate. First bore segment 162 and second bore segment 161 may themselves be straight bores.
In addition, the apparatus 100 may further include a power supplier 150 (see fig. 2). The power supplier 150 may be a secondary battery. The power supply 150 may be provided in the above-described boss 111, preferably in a different but adjacent boss 111 than the data acquisition mechanism 140 and the data transmission mechanism 130. Thus, the power supplier 150 may supply power to the data acquisition mechanism 140 and the data transmission mechanism 130 through the respective cables to allow the normal operation thereof. For example, a structure similar to the first and second hole sections 162 and 161 described above may be provided between the power supply 150 and the data acquisition mechanism 140 and/or between the power supply 150 and the data transmission mechanism 130 for the cable to pass through.
Fig. 1 also shows a specific structure of the data transmission mechanism 130. The data transmission mechanism 130 includes a transducer 131 for converting data from the data acquisition mechanism 140 into a sound wave form, and a launch canister 132 for transmitting the data in the sound wave form. The converter 131 may be a circuit board. Which can be mounted on the circuit framework of the groove. Converter 131 may include a node 131A for receiving data, e.g., in the form of electrical signals, from data acquisition mechanism 140. The converter 131 may further include a node 131B for receiving power provided by the power supply 150. Transducer 131 may also include a node 131C for receiving a drive circuit operable to drive an acoustic wave transducer to generate an acoustic wave signal. The converter 131 itself is well known to those skilled in the art and will not be described in detail herein.
The data in the form of acoustic waves converted by the converter 131 may be transferred to the launch canister 132, and the launch canister 132 may transmit the data in the form of acoustic waves. The launch canister 132 may be formed, for example, in a truncated cone shape. One end thereof having a larger cross section is set as a front end, i.e., an end facing the data receiving mechanism 170; the end thereof having a smaller cross section is set as a rear end, i.e., the end facing away from the data receiving mechanism 170.
Preferably, the front end of the launch barrel 132 is covered by a front cover plate 133. The front cover plate 133 may be made to facilitate the propagation of acoustic waves so that a substantial portion of the energy generated by the acoustic wave transducer may be efficiently radiated out of the front end of the launch canister 132. For this, the front cover plate 133 may be made of light metal such as aluminum alloy, aluminum magnesium alloy, and/or titanium alloy.
Preferably, the rear end of the launch canister 132 is covered by a rear cover plate 134. The back cover plate 134 may be made to be unfavorable for the propagation of sound waves, thereby ensuring that the energy generated by the sound wave transducer is not radiated from the rear end of the launch barrel 132 as much as possible. To this end, the rear cover plate 134 may be made of some heavy metal. For example, a piezoceramic transducer may be fabricated using 45 gauge steel for the backplate 134.
In the embodiment shown in fig. 1, a front cover plate 133, a launch barrel 132, a rear cover plate 134 and a converter 131 are arranged in the cavity formed by the boss 111 in this order from top to bottom. The front cover 133 abuts the upper wall of the chamber and the transducer 131 abuts the lower wall of the chamber. This arrangement is very compact and space-saving. Meanwhile, the arrangement mode is beneficial to the effective transmission of sound waves.
In addition, as shown in fig. 1, the data receiving mechanism 170 may be provided at the upper end of the motor 110, for example, may be provided in the outer wall of the bypass valve at the upper end of the motor 110. Thus, the apparatus 100 of the present application may be incorporated into existing, standardized power drills 110 by light machining thereof.
The data receiving mechanism 170 is preferably disposed in the same sub as the data sending mechanism 130. That is, there is no nipple connection between the data receiving mechanism 170 and the data sending mechanism 130. The attenuation of the sound wave in the transmission process can be greatly reduced through the arrangement, so that the effectiveness and the reliability of data transmission can be improved.
In addition, as shown in fig. 1, the data receiving mechanism 170 is configured with a receiving cylinder 171 having a substantially truncated cone shape. The front end (i.e., the end having the larger cross-section) of the receiving cylinder 171 faces the launching cylinder 132; the rear end (i.e., the end having a smaller cross-section) of the receiving cylinder 171 faces away from the launching cylinder 132.
The data receiving mechanism 170 receives data in the form of sound waves and converts it into an electrical signal form. The data in the form of electrical signals are transmitted to the data processing means 180, and are subjected to noise reduction, amplification, filtering, and the like by the data processing means 180. The processed data can be directly transmitted to the surface, or can be transmitted to a downhole computer module or a hard connection and an electrical interface of an MWD device or other instruments, and then transmitted to the surface after corresponding processing.
The data processing mechanism 180 may be on a different sub than the data receiving mechanism 170. For example, in fig. 1, a data transfer sub 120 (e.g., an existing communication sub, including MWD, etc. upper instruments) is connected to the upper end of the power drill 110. Data processing mechanism 180 is embedded within the wall of the data transfer sub 120. In order to ensure the electrical connection between the data processing means 180 and the data receiving means 170, the following arrangement may be made. As shown in fig. 1, a first transfer cable 191 may be configured between the signal receiving mechanism 170 and the upper end surface of the power drill. The first transfer cable 191 is embedded in the wall of the power drill. Accordingly, a second transmission cable 192 is configured between the signal processing mechanism 180 and the lower end face of the data transmission nipple 120. A second transfer cable 192 is embedded within the wall of the data transfer sub 120. As shown in fig. 3, a first conductive ring 193 is provided on the upper end surface of the power drill 110, and the first conductive ring 193 is connected to the first transmission cable 191. Accordingly, a second conductive ring (not shown) is disposed on the lower end face of the data transfer nipple 120, and is connected to the second transfer cable 192. The first conductive ring 193 and the second conductive ring are in contact when the data transfer sub 120 is connected to the power drill 110. Thus, when the power drill 110 rotates relative to the data transmission nipple 120, effective electrical connection between the signal processing mechanism 180 and the data receiving mechanism 170 can be achieved, and thus effective data transmission can be achieved.
It should be understood that two mutually parallel first transfer cables 191 and two mutually parallel second transfer cables 192 may be provided as shown in fig. 1. Accordingly, two concentric first conductive rings 193 and two concentric second conductive rings are provided. Thus, the transmission of electric energy and data can be realized respectively.
However, preferably, only one first transfer cable 191, one second transfer cable 192, one first conductive ring 193, and one second conductive ring may be provided. Thereby achieving the transmission of power and data simultaneously. This arrangement is very advantageous for downhole structures of limited size.
As shown in fig. 3, a first insulating ring 194 and a second insulating ring 195, which are concentric, are disposed inside and outside the first conductive ring 193, respectively. The two insulating rings can play a role in sealing, so that on one hand, the electric leakage at the conducting ring can be avoided, and on the other hand, the conducting ring can be prevented from being corroded by cement paste in the annular space. This is very advantageous to ensure efficient transmission of data.
The apparatus 100 described above is capable of efficiently performing near-bit data acquisition and data transmission. Meanwhile, the device 100 has the advantages of low cost, high reliability and very high practicability.
It should be understood that in this document, the words "upper", "lower", and the like are relative terms. As defined herein, unless otherwise specified or clearly contradicted by context, "up" is a direction relatively close to the wellhead and "down" is a direction relatively close to the bottom of the well.
It should also be understood that the structures and manners of the devices for signal transmission and signal processing mentioned in the present document, which can realize signal transmission and signal processing, are all known in the art. The present invention relates only to improvements in the peripheral structure thereof (e.g., front and rear cover plates), and in the arrangement of devices and the like.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict.
