Description

TECHNICAL FIELD

[0001] The present application relates to the field of petroleum engineering drilling technology, and particularly relates to a drilling bit drilling front exploration processing device and method. BACKGROUND

[0002] This section is intended to provide background information to facilitate an understanding of embodiments of the application as set forth in the claims. The description herein does not constitute admission of prior art.

[0003] In the process of oil drilling, formation changes often occur, and drilling into caves, cracks, abnormal high pressure, faults, folds and other situations occur from time to time, which can cause problems such as lost circulation, overflow, formation collapse and sticking of the drill pipe, and abnormal wear of the drill bit. If not handled in time, it will also cause catastrophic accidents such as blowout.

[0004] At present, drilling mainly relies on seismic, geophysical methods, and refers to the real drilling data of adjacent wells to obtain the geological characteristics and oil and gas water conditions of the formation to be drilled. These methods have limitations, and the problem of inconsistency between real drilling geological characteristics and oil and gas water conditions and prediction often occurs. Some scholars have also considered that due to the lack of formation geological characteristics and oil and gas water conditions data during drilling, accidents such as overflow, lost circulation and collapse and sticking often occur. Research on the function of drill bit drilling formation front exploration, real-time detection of the geological characteristics and oil and gas water characteristics of the formation to be drilled, provides a basis for risk identification of the formation to be drilled, reduces the drilling risk, improves the drilling efficiency, and ensures the safety of drilling. However, in the current drill bit drilling formation front exploration scheme, the drill tool structure is complex, and the downhole wiring of the drill bit sensor is complex. Due to the limited space of the downhole drill pipe and drill bit, wired transmission will occupy a certain space, reduce the wall thickness of the drill tool, and the strength of the drill tool will decrease, and the safety will decrease.

[0052] In one embodiment, the second wireless signal processing module is specifically configured to use a radiative wireless energy transmission technology to wirelessly transmit power to the first wireless signal processing module.

[0053] In a specific implementation, wireless power supply, wireless energy transmission or wireless power transmission is a technology for transferring power energy from a power generation device or a power supply end to a power receiving device without passing through an electric conductor. Wireless energy transmission is a general term that can be achieved using various different technologies, including electric fields, magnetic fields, and electromagnetic waves. The transmitter converts electrical energy into the energy state of the corresponding field, transmits through a space, and is received by one or more receivers and converted back into electrical energy. Wireless energy transmission technology is divided into two categories: non-radiation and radiation. Non-radiation technology uses inductive coupling between coils to transmit energy through magnetic fields. Radiation technology uses directional energy beams such as microwaves and lasers to transmit energy. This technology can transmit over long distances. The embodiment of the present application uses radiation type wireless energy transmission technology to wirelessly transmit electrical energy to the first wireless signal processing module, and has the function of 2-10m wireless energy and signal synchronous transmission across the drill bit.

[0054] In order to facilitate understanding of how the present application is implemented, the following is a general introduction to the drill ahead-while-drilling scheme.

[0055] ①The wireless energy and signal transmission module (the first wireless signal processing module and the second wireless signal processing module) has the function of 2-10m wireless energy and signal synchronous transmission across the drill bit (the embodiment of the present application uses radiation type wireless energy transmission technology, i.e. microwave directional energy waves are connected with sensors and communication modules on the drill bit to realize electrical energy transmission and signal interaction), which is used to provide an electrical energy and signal transmission channel for the radar electromagnetic wave detector in front of the drill bit.

[0056] ②The detection sensor is used to transmit and receive signals. These signals can be directly the lithology of the formation, such as gamma, resistivity, neutron density, and porosity, oil and gas parameters, etc. Because the measurement data can be relatively large, if the data volume is too large, these signals can also be signals that are pre-processed, compressed, and encoded for transmission to improve transmission efficiency, as shown in Figure 1 and Figure 2 The sensor can be installed at the end of the drill bit nozzle. This method currently has the smallest modification to the drill bit, and can also be expanded into a special drill bit with a special drill bit to meet the needs of the front exploration, with sensors installed on it.

[0057] ③The power supply module is used to provide power for the detection sensor, the downhole data processing module, and the communication module. When supplying power to the detection sensor, the wireless energy transmission module is used for electrical energy transmission.

[0058] ④The communication module is used to establish communication between the modules. When communicating with the detection sensor, the wireless energy and signal transmission module is used for communication.

[0061] The embodiment of the present application utilizes wireless energy transmission to transmit energy and signals across a short distance in space. The drill bit sensor is connected to the wireless signal processing module above the drill bit by using wireless transmission technology, which is beneficial to simplify the complex wiring technology in the downhole, save the limited space of the drill pipe and drill bit, and improve the safety of the drilling tool and the reliability of the transmission.

[0062] The present application utilizes wireless energy and signal transmission to realize energy and signal transmission across the drill bit, solves the problem that the detection sensor installed on the drill bit cannot be powered and cannot transmit signals, and integrates the detection sensor with energy and signal transmission functions, which can be installed on the ordinary PDC drill bit as a conventional drill bit nozzle. The conventional drill bit does not need to be modified to realize accurate and real-time detection of the geological features of the formation in front of the drill bit during drilling, and the data is transmitted to the ground. The measurement function of the geological features and the oil and gas water features of the formation to be drilled provides a basis for risk identification of the formation to be drilled, reduces the drilling risk, improves the drilling efficiency, ensures the safety of drilling, and has a wide application prospect.

[0063] The embodiment of the present application also provides a processing device for the drill bit while drilling and front-probing, as described in the following embodiment. Since the principle of solving the problem of the device is similar to the processing method of the drill bit while drilling and front-probing, the implementation of the device can be referred to the implementation of the processing method of the drill bit while drilling and front-probing, and the repeated parts will not be described again.
