Description

Technical Field

[0001] The invention relates to the technical field of logging while drilling, and in particular to a logging while drilling data transmission device and a transmission method using a drill pipe as an antenna. Background Art

[0002] Logging while drilling technology and equipment have been around since the 1930s, but because real-time data transmission could not be achieved, the only option was to use data storage and export the data for processing after the rod was withdrawn, which greatly reduced its effectiveness.

[0003] Existing logging while drilling technologies generally use two methods: wireless transmission and wired transmission. Although wireless transmission has a relatively simple structure and low cost, it has a low rate and a limited amount of data transmitted. Although wired transmission has a high transmission rate, it has a complex structure and high cost. It also requires communication to be interrupted when changing rods, which makes on-site construction inconvenient. Summary of the invention

[0004] To this end, it is necessary to provide a while-drilling logging data transmission device and transmission method using a drill pipe as an antenna to solve the technical problems of low wireless transmission rate and limited transmission data volume; complex wired transmission structure, high cost, need to interrupt communication when changing rods, and inconvenient on-site construction.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a logging while drilling data transmission device using a drill pipe as an antenna, comprising:

[0006] The well logging mechanism includes a compensation impedance module, a wireless communication module, a well logging acquisition module, a microcontroller module and a power supply module. The compensation impedance module is connected to the wireless communication module, the microcontroller module is respectively connected to the well logging acquisition module and the wireless communication module, and the power supply module supplies power to the wireless communication module, the well logging acquisition module and the microcontroller module;

[0007] A connecting component, the connecting component comprising a first connector and a second connector;

[0008] Two or more drill pipes, which are connected in sequence and then connected to one side of the logging mechanism through a first connector;

[0009] a drill bit connected to the other side of the logging mechanism via a second connector;

[0010] Among them, more than two drill pipes, a first connector, a logging mechanism, a second connector and a drill bit are connected in sequence to form a drill pipe antenna, and the drill pipe antenna is connected to the compensation impedance module.

[0011] Different from the prior art, the above technical solution is provided with two or more drill rods connected to a specified length and then connected to the first connector, the logging mechanism, the second connector and the drill bit in sequence to form a drill rod antenna. The drill rod antenna serves as a data transmission antenna, so that the computer communicates data with the microcontroller module in the logging mechanism through the drill rod antenna. The drill rod can be directly connected, which is convenient for construction and low in cost. In addition, the connection of two or more drill rods in sequence extends the length of the antenna, making the transmission rate of the transmission device high, stable and reliable.

[0012] As an embodiment of the present invention, the logging mechanism also includes a module fixing frame and a shell. The shell is arranged outside the module fixing frame. The module fixing frame is equipped with a compensation impedance module, a wireless communication module, a logging acquisition module, a microcontroller module and a power supply module. The two sides of the module fixing frame are respectively connected to the first connector and the second connector.

[0013] In this way, the modules of the logging mechanism can be easily installed through the module fixing frame. In addition, a shell is arranged outside the module fixing frame to protect the modules of the logging mechanism.

[0014] As an implementation mode of the present invention, the housing is provided with two or more diffusion holes at the well logging acquisition module.

[0015] In this way, by providing the diffusion holes, the acquisition signal of the well logging acquisition module can be transmitted through the housing through more than two diffusion holes, thereby improving the acquisition range and acquisition accuracy of the well logging acquisition module.

[0016] As an embodiment of the present invention, the well logging mechanism further includes a non-metallic block, and the non-metallic block is filled in the diffusion hole.

[0017] Thus, the non-metallic block is less likely to shield the signal than the metal block and has good transmission performance. By filling the diffusion hole with the non-metallic block, it is prevented that impurities or water enter the diffusion hole during the drilling process, thereby affecting the operation of the logging mechanism.

[0018] As an embodiment of the present invention, the module fixing frame is provided with a compensation impedance module placement portion, a wireless communication module placement portion, a well logging acquisition module placement portion, a microcontroller module placement portion and a power supply module placement portion in sequence from left to right in the horizontal direction;

[0020] In this way, each module is installed at a designated position on the module fixing frame, which facilitates the connection between the modules and enables each module to function.

[0021] As an embodiment of the present invention, the module fixing frame further includes a base, two first support plates and two second support plates;

[0022] The base is provided with a compensation impedance module placement portion, a wireless communication module placement portion, a logging acquisition module placement portion, a microcontroller module placement portion and a power supply module placement portion in sequence from left to right along the horizontal direction. The base is provided with two first support plates on both sides of the compensation impedance module, and the base is provided with two second support plates on both sides of the power supply module.

[0023] Thus, the cross-sections of the first support plate and the second support plate are circular, which can strengthen the support of the base and facilitate the housing to be mounted outside the module fixing frame; on the other hand, the compensation impedance module and the power supply module can be separated from other modules.

[0024] As an embodiment of the present invention, the logging mechanism also includes a first fixed head and a second fixed head, the first fixed head and the second fixed head are respectively installed on both sides of the shell, the first fixed head is connected to the first connector by mortise and tenon, and the second fixed head is connected to the second connector by mortise and tenon.

[0025] In this way, the installation or subsequent disassembly between the fixing head and the connector is facilitated by the mortise and tenon connection.

[0026] As an embodiment of the present invention, the first fixing head and the second fixing head are both straight-line terminals, and the first connector and the second connector both have straight-line grooves inside, and the straight-line grooves are correspondingly connected to the straight-line terminals.

[0027] In this way, the fixed head is set as a straight-line terminal, the connector has a straight-line groove that matches the straight-line terminal, and the straight-line terminal is inserted into the straight-line groove.

[0028] As an embodiment of the present invention, the first fixing head and the second fixing head are both round ends, and the first connector and the second connector both have round grooves inside, and the round grooves are correspondingly connected to the round ends.

[0029] Thus, the fixed head is similarly set to be a round end, the connector has a round groove that matches the flat end, and the round end is inserted into the round groove.

[0030] To achieve the above object, in a second aspect, the inventor provides a method for transmitting logging while drilling data using a drill pipe as an antenna, comprising any one of the logging while drilling data transmission devices using a drill pipe as an antenna provided by the inventor above, and further comprising the following steps:

[0031] S101: connecting two or more drill pipes to a specified length in sequence and then threading them to one side of a first connector, connecting the other side of the first connector to one side of a logging mechanism, connecting the other side of the logging mechanism to one side of a second connector, and threading the other side of the second connector to a drill bit, to finally form a drill pipe antenna;

[0032] S102: The microcontroller module controls the logging acquisition module to acquire logging signals and transmits the acquired logging signals to the computer in real time through the wireless communication module, wherein the drill pipe antenna can increase the communication distance of the wireless communication module, thereby increasing the transmission range of the while-drilling logging data transmission device using the drill pipe as the antenna.

[0033] Different from the prior art, the technical solution of the present application improves the transmission range and transmission rate of a while-drilling logging data transmission device using a drill pipe as an antenna under the action of a drill pipe antenna.

[0056] The two or more drill rods 3, the first connector 21, the logging mechanism 1, the second connector 22 and the drill bit 4 are all made of metal materials with low resistivity; and the contact resistance of the connection between them is less than 50 milliohms. Among them, the resistance value of the compensation impedance module 11 is between 25 ohms and 30 ohms. The compensation impedance module 11 can improve the stability and performance of the circuit system.

[0057] The above technical solution is provided with two or more drill rods 3 connected to a specified length and then connected to the first connector 21, the logging mechanism 1, the second connector 22 and the drill bit 4 in sequence to form a drill rod antenna 5.
