Description

Technical Field

[0001] This invention relates to the field of oil drilling technology, and in particular to a radar electromagnetic wave-based pre-drilling device and method. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] During oil drilling, formation changes are frequent, and encounters with caverns, fractures, abnormally high pressure, faults, and folds are common. These encounters can lead to problems such as lost circulation, blowouts, formation collapse, stuck pipe, and abnormal drill bit wear. If not addressed promptly, these issues can result in catastrophic accidents like blowouts. Currently, methods such as seismic and geophysical exploration, along with data from adjacent wells, are used to obtain information on the geological characteristics and oil, gas, and water content of the formation to be drilled. However, these methods have limitations, and discrepancies between actual geological characteristics and predicted oil, gas, and water content are common. Conventional drilling currently lacks the capability for real-time formation exploration (MRV) during drilling. The lack of data on the geological characteristics and oil, gas, and water content of the formation to be drilled during the drilling process frequently leads to blowouts, lost circulation, and stuck pipe. Therefore, it is necessary to research MRV methods to conduct real-time exploration of the geological characteristics and oil, gas, and water content of the formation to be drilled, providing a basis for identifying formation risks, reducing drilling risks, improving drilling efficiency, and ensuring drilling safety. Currently, in China's drilling-while-probing methods, the detectors are exposed to the outside for extended periods, leading to unreliable detection parameters and safety issues during the exploration process.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0025] This invention relates to a radar-based electromagnetic wave-based pre-drilling exploration scheme, applicable to formation exploration in the oil and gas drilling industry. Specifically, it refers to a method and apparatus for radar-based electromagnetic wave-based pre-drilling exploration, which utilizes radar electromagnetic waves to detect the lithological characteristics and oil, gas, and water-bearing features of the formation to be drilled. Belonging to the field of petroleum engineering drilling, it provides a basis for identifying risks in the formation to be drilled, ensuring drilling safety. The radar-based electromagnetic wave-based pre-drilling exploration scheme is described in detail below.

[0026] Figure 1 This is a schematic diagram of the structure of the radar electromagnetic wave-based pre-drilling device in an embodiment of the present invention, as shown below. Figure 1 As shown, the device includes: a second processing module, a short-section housing, and a communication module, a first processing module, a detector motor actuator, a detector bracket, and a radar electromagnetic wave detector disposed within the housing; wherein:

[0027] The first processing module is used to send an activation command to the detector motor actuator when the preset triggering strategy is met during the drilling process, and send the lithological characteristic data and oil, gas and water characteristic data of the formation to be drilled to the second processing module through the communication module.

[0028] The detector motor actuator is connected to the first processing module and the detector bracket, and is used to operate when an opening command is received, so as to drive the detector bracket to extend out of the short section housing and drive the radar electromagnetic wave detector to extend out of the short section housing.

[0029] A radar electromagnetic wave detector is installed at the end of the detector bracket facing the formation to be drilled. It is used to detect the lithological characteristics and oil, gas and water characteristics of the formation to be drilled when it extends outside the short section shell, and send the detected lithological characteristics and oil, gas and water characteristics of the formation to be drilled to the first processing module.

[0030] The second processing module, connected to the communication module, is used to identify risks in the formation to be drilled based on the lithological characteristics and oil, gas and water-bearing characteristics of the formation.

[0031] The radar electromagnetic wave-based pre-drilling exploration device provided in this embodiment of the invention operates as follows: When a preset triggering strategy is met during drilling, the first processing module sends an activation command to the detector's motorized actuator, transmitting lithological and oil / gas / water characteristic data of the formation to be drilled to the second processing module via the communication module. Upon receiving the activation command, the detector's motorized actuator operates, driving the detector support to extend outside the short-section housing, thereby extending the radar electromagnetic wave detector outside the short-section housing. While extended outside the short-section housing, the radar electromagnetic wave detector detects the lithological and oil / gas / water characteristic data of the formation to be drilled and transmits this data to the first processing module. The second processing module performs risk identification on the formation based on the lithological and oil / gas / water characteristic data, enabling safe and reliable pre-drilling exploration based on radar electromagnetic waves.

[0032] In one embodiment, the first processing module is specifically used to send an opening command to the detector's motorized actuator when the drilling distance meets a preset length.

[0033] In practice, the probe automatically extends every 30 to 50 meters (preset length) for detection. Depending on the lithology, oil, gas and water conditions of the formation, it automatically retracts if everything is normal. If the received parameters such as gamma, resistivity, neutron density and porosity are abnormal, it does not retract, thus increasing the density of measurements and improving the effectiveness and flexibility of the detection.

[0034] In one embodiment, the first processing module is specifically used to send an activation command to the detector motor actuator when the drilling time meets the preset time.

[0035] In practice, the probe automatically extends every 10-15 minutes (preset duration) to conduct detection. Depending on the lithology, oil, gas and water conditions of the formation, it automatically retracts if everything is normal. If the received parameters such as gamma, resistivity, neutron density and porosity are abnormal, it does not retract, thus increasing the density of measurements and improving the effectiveness and flexibility of the detection.

[0036] In one embodiment, the second processing module is further configured to send an encrypted detection command to the first processing module through the communication module when the target feature data is determined to be discovered after the feature code is converted into corresponding lithological feature data and oil, gas and water feature data.

[0037] The first processing module is also used to control the detector's motor actuator to extend the time it extends out of the housing according to the encrypted detection command, so as to extend the detection time of the radar electromagnetic wave detector.

[0038] In specific implementation, when the second processing module converts the feature code into corresponding lithological feature data and oil, gas and water feature data and determines that the target feature data has been discovered, it sends an encrypted detection command to the first processing module through the communication module. The first processing module is also used to control the detector's motor actuator to extend the time it extends out of the shell according to the encrypted detection command, so as to extend the detection time of the radar electromagnetic wave detector and further improve the detection effectiveness.

[0039] In one embodiment, the second processing module is further configured to send a stop detection command to the first processing module through the communication module when the target feature data is determined to be found within a preset length after the feature code is converted into corresponding lithological feature data and oil, gas and water feature data;

[0040] The first processing module is also used to control the detector's motor actuator to retract into the housing when a stop detection command is received, such as... Figure 2 As shown.

[0041] In specific implementation, the second processing module converts the feature code into corresponding lithological feature data and oil, gas and water feature data. When it determines that no target feature data is found within a preset length, it sends a stop detection command to the first processing module through the communication module. The first processing module is also used to control the detector's motor actuator to retract into the housing when it receives the stop detection command, further saving detection resources.

[0042] In one embodiment, the aforementioned radar electromagnetic wave-based drilling exploration device may further include: a power supply module connected to the radar electromagnetic wave detector, the first processing module, the communication module, and the detector motor actuator, for supplying power to the radar electromagnetic wave detector, the first processing module, the communication module, and the detector motor actuator.

[0043] In practice, a power supply module is used to supply power to the radar electromagnetic wave detector, the first processing module, the communication module, and the detector's motorized actuator, thereby improving the accuracy of the detection.

[0044] To facilitate understanding of how this invention is implemented, a detailed description is provided below.

[0045] A device based on radar electromagnetic waves for forward drilling, such as Figure 1 As shown, it includes a radar electromagnetic wave detector, a detector bracket, a detector actuator, a power supply module, a first processing module, a second processing module, and a communication module. The detector bracket can extend and retract; its extension and retraction are controlled by the detector's motorized actuator (e.g., ...). Figure 2As shown, the actuator may include an extendable and retractable bracket and a hydraulic support, etc. The radar electromagnetic wave detector is mounted on the bracket. The power supply module, the first processing module, the detector's motorized actuator, and the communication module are integrated into a short section, wherein:

[0046] The radar electromagnetic wave detector is used to transmit and receive signals (lithological characteristic data and oil, gas, and water-bearing characteristic data of the formation to be drilled), and is installed at the bottom of the support (closest to the formation to be drilled). The power supply module provides power to the radar electromagnetic wave detector, the first processing module, the communication module, and the detector's motorized actuator. The communication module establishes communication between the modules. The first processing module compares the geological feature data collected by the radar electromagnetic wave detector with existing data models and converts the collected geological features into geological feature codes according to a predetermined encoding method to reduce data transmission volume and improve data transmission efficiency. The second processing module issues forward exploration commands and decodes the geological feature codes transmitted downhole into readable geological feature data. The detector's motorized actuator mainly consists of a hydraulic system used to retract and extend the detector support.

[0047] The specific implementation method of the radar electromagnetic wave-based drilling probe is as follows:

[0048] Step 1: On the ground, using experimental equipment, establish the characteristic relationship between feature codes and lithological feature data and oil, gas and water feature data, and write the above relationship into the databases of the first processing module and the second processing module.

[0049] Step 2: The radar electromagnetic wave drilling exploration system is lowered to the bottom of the well. When it is necessary to conduct exploration of the formation to be drilled, the second processing module issues a forward exploration command, and the detector motor actuator opens the detector support.

[0050] Step 3: The communication module and power supply module control the activation of the radar electromagnetic wave detector. The radar electromagnetic wave detector detects the geological features ahead and transmits the data to the first processing module. The first processing module compares the collected geological feature data with the above-mentioned relationships and converts the collected geological features into geological feature codes according to the predetermined encoding method. Here, a pre-trained neural network model can be used for recognition and conversion. This model is generated in advance using feature codes and lithological feature data and oil, gas and water feature data feature relationship data samples.

[0051] Step 4: The communication module transmits the geological feature code to the second processing module. The second processing module compares the geological feature code transmitted downhole with the above-mentioned relationships in the database or inputs it into the neural network model for recognition and conversion, decodes it into readable geological feature data and displays it for technicians to analyze and identify drilling risks.

[0052] Step 5: When the detection ends, the second processing module issues a command, the detector's motor actuator retracts the detector bracket, and the communication module controls the power supply module to shut down the power supply to the detector's motor actuator, the radar electromagnetic wave detector, and the first processing module, thus ending the detection.

[0053] In summary, the embodiments of the present invention have the following technical effects: They enable precise real-time detection of the geological features of the formation ahead during drilling and transmit the data to the surface. The measurement functions of the geological features and oil, gas, and water-bearing characteristics of the formation to be drilled provide a basis for risk identification of the formation, thereby reducing drilling risks, improving drilling efficiency, and ensuring drilling safety. Furthermore, the detector's motorized actuator operates upon receiving an activation command, driving the detector support to extend outside the short section housing, and consequently, the radar electromagnetic wave detector to extend outside the short section housing. The radar electromagnetic wave detector extends or retracts according to a preset strategy, ensuring that the detector is not exposed to the outside for extended periods, thus enabling safe and reliable forward exploration based on radar electromagnetic waves.

[0054] This invention also provides a method for advance drilling based on radar electromagnetic waves, as described in the following embodiments. Since the principle behind this method is similar to that of the advance drilling device based on radar electromagnetic waves, its implementation can refer to the implementation of the advance drilling device based on radar electromagnetic waves; repeated details will not be elaborated further.

[0067] Step 302: When the first processing module receives the stop detection command, it controls the detector's motor actuator to retract into the housing.

A method for advance drilling based on radar electromagnetic waves, characterized in that, This method is applied to a radar-based pre-drilling exploration device, which includes: a second processing module, a short-section housing, and a communication module, a first processing module, a detector motorized actuator, a detector support, and a radar electromagnetic wave detector disposed within the housing; the databases of the first and second processing modules pre-establish the characteristic relationships between geological feature codes, lithological feature data, and oil, gas, and water-bearing feature data; this radar-based pre-drilling exploration method includes: When the preset triggering strategy is met during drilling, the first processing module sends an activation command to the detector's motorized actuator. It then compares the geological feature data of the strata to be drilled collected by the radar electromagnetic wave detector with the existing data model. Based on the relationship between the geological feature codes and the lithological feature data and oil, gas and water feature data, the collected geological features are converted into geological feature codes and sent to the second processing module through the communication module. The geological feature data includes lithological feature data and oil, gas and water feature data. When the detector motor actuator receives an activation command, it operates to drive the detector bracket to extend out of the short section housing, thereby causing the radar electromagnetic wave detector to extend out of the short section housing. The detector motor actuator is connected to the first processing module and the detector bracket. When the detection ends, it drives the radar electromagnetic wave detector to retract into the short section housing. When the radar electromagnetic wave detector extends outside the short section shell, it detects the lithological characteristics and oil, gas and water-bearing characteristics of the formation to be drilled, and sends the detected lithological characteristics and oil, gas and water-bearing characteristics of the formation to be drilled to the first processing module; the radar electromagnetic wave detector is set at the end of the detector support facing the formation to be drilled; the radar electromagnetic wave detector extends or retracts according to a preset strategy, and the detector will not be exposed to the outside for a long time. The second processing module decodes the geological feature codes transmitted by the first downhole processing module into readable geological feature data according to the relationship between the geological feature codes, lithological feature data, and oil, gas, and water feature data. Based on the readable geological feature data of the formation to be drilled, the module performs risk identification on the formation to be drilled. The readable geological feature data includes readable lithological feature data and oil, gas, and water feature data. The second processing module is connected to the communication module. When the second processing module determines that target feature data has been discovered based on the lithological and oil, gas and water characteristics data of the formation to be drilled, it sends an encrypted detection command to the first processing module through the communication module. According to the encrypted detection command, the first processing module controls the detector's motor actuator to extend the time it extends out of the housing, so as to extend the detection time of the radar electromagnetic wave detector. When the second processing module determines that no target feature data has been found within a preset length based on the lithological and oil, gas and water characteristics data of the formation to be drilled, it sends a stop detection command to the first processing module through the communication module. When the first processing module receives the stop detection command, it controls the detector's motor actuator to retract into the housing.
