Description

Technical Field

[0001] This invention belongs to the field of drilling exploration technology, specifically relating to a multi-parameter logging-while-drilling data acquisition device for exploration, and also to a multi-parameter logging-while-drilling data acquisition method for exploration. Background Technology

[0002] Logging while drilling (LoWW) is an exploration technique that simultaneously measures formation during drilling. LoWW integrates logging instruments near the drill collar or drill bit. As the drill bit rotates through the formation, the logging instruments acquire formation physical parameters in real time, significantly improving drilling exploration efficiency. Currently, to ensure the diversity of logging data during LoWW operations, multiple sets of different types of logging sensors are typically integrated and fixedly installed on the logging instruments. Due to the vibration of the drill bit during long-term drilling operations, the integrated logging sensors are prone to electronic component damage, causing some sensors to malfunction in formation sensing. Therefore, it is necessary to completely remove and replace the logging instrument from the drill string. It is evident that in traditional LoWW, the multiple sets of logging sensors cannot be modularly disassembled and replaced. Replacing the entire logging instrument wastes undamaged sensors and increases the replacement and maintenance costs of LoWW equipment. Summary of the Invention

[0003] The primary objective of this invention is to provide a multi-parameter logging-while-drilling data acquisition device for exploration, thereby solving the problem that multiple logging sensors in traditional logging-while-drilling instruments cannot be individually disassembled and replaced in the prior art.

[0004] The second objective of this invention is a method for acquiring multi-parameter logging-while-drilling data for exploration.

[0005] The first technical solution adopted in this invention includes a bottom cover; the upper side of the bottom cover is connected to the organic cylinder shell by bolts, and a data acquisition and control unit is installed on the inner side of the cylinder shell; it also includes a sleeve shell and a multi-parameter logging device; the bottom end of the sleeve shell is connected to the organic cylinder shell by bolts.

[0006] The first technical solution of this invention is also characterized in that,

[0007] The multi-parameter logging device includes a data interface mounting frame, a plug block, and a locking rod; the data interface is mounted on the outer side of the mounting frame, and a sleeve shell is welded to the outer side of the mounting frame near the bottom. A locking shell is welded to the upper side of the mounting frame, and the locking shell is engaged with a rotating drum engagement connection. A pinch plate is welded to the center of the top of the insert block, a data connector is installed at the center of the lower side of the insert block, and a logging sensor is installed on the outer side of the insert block; a tension spring is nested on the outer side of the support rod, a placement frame is slidably connected to the outer side of the support rod, and a locking tongue block is welded to the end of the support rod.

[0008] The casing is a cylindrical structure that runs vertically through the casing. The entire casing is made of stainless steel. The multi-parameter logging device is embedded inside the cylindrical structure of the casing.

[0009] There are six sets of insert blocks, each set of insert blocks is a fan-shaped column structure, the fan-shaped column of the insert block is provided with a rectangular groove, and the outer side of each set of insert blocks is equipped with logging sensors. The six sets of logging sensors are temperature sensor, vibration sensor, neutron porosity sensor, ultrasonic caliper sensor, acoustic pressure sensor and inductive resistivity sensor.

[0010] The lock case is a cylindrical structure that runs vertically through the top and bottom. Near the bottom of the outer side of the cylindrical structure, there are six sets of rectangular through slots that run through the inside and outside. The rectangular through slots are arranged in a circular array around the vertical central axis of the cylindrical structure. Each set of rectangular through slots is fitted with a latch block. The upper side of the latch block has a beveled structure. The inner side of the cylindrical structure has a threaded structure.

[0011] The rotating drum has a cylindrical structure, and the outer surface of the cylindrical structure of the rotating drum is threaded. The threaded connection of the outer surface of the rotating drum is engaged with the threaded structure on the inner surface of the lock housing.

[0012] There are six sets of pinching plates, and each set of pinching plates has long strip-shaped raised patterns densely distributed on the left and right sides; there are six sets of tension springs, with a locking tongue block welded to one end of the tension spring and a placement rack welded to the other end of the tension spring.

[0013] The outer side of the placement frame has six sets of fan-shaped grooves, which are arranged in a circular array around the vertical central axis of the placement frame. Insert blocks are embedded in the fan-shaped grooves of the placement frame. The bottom of each set of fan-shaped grooves has a circular through hole. A data interface is installed in the circular through hole of the placement frame. A data connector is plugged into the data interface socket. The data connector is connected to the logging sensor through a wire, and the data interface is connected to the data acquisition and control unit through a wire.

[0014] The second technical solution adopted in this invention is a multi-parameter logging-while-drilling data acquisition method for exploration, comprising the following steps: S1, insert the plug with the logging sensor into the groove of the placement frame to make the data connector and data interface connected, and complete the connection between the sensor and the data acquisition and control unit; S2, rotate the drum, and drive the locking tongue block to lock the plug through the threaded engagement to ensure stable insertion; S3, the logging-while-drilling sensor collects formation and drill string parameters, which are then transmitted to the data acquisition and control unit via data connectors and data interfaces to complete the acquisition of multi-parameter logging-while-drilling data.

[0015] The second technical solution of the present invention is further characterized in that, When the logging sensor is damaged, rotate the drum in the opposite direction. The pull spring will cause the locking tongue block to retract, releasing the locking of the insertion block. Use the pinch plate to pull the corresponding insertion block out of the groove of the placement frame. After replacing it with a new insertion block with a good logging sensor, repeat S1-S2 to complete the independent replacement of the damaged logging sensor. In S3, when the rotating cylinder is rotated, it rotates downward along the internal thread of the lock housing, simultaneously pushing the inclined structure of the six sets of locking tongue blocks, so that the six sets of locking tongue blocks are simultaneously inserted into the rectangular grooves of the corresponding inserts, completing the synchronous locking of the six sets of inserts; when the rotating cylinder is rotated in the opposite direction to move upward along the internal thread of the lock housing, the rotating cylinder disengages from the locking tongue blocks, and the six sets of tension springs synchronously drive the six sets of locking tongue blocks to retract into the through grooves of the lock housing through elastic tension, completing the synchronous unlocking of the six sets of inserts.

[0016] The beneficial effects of this invention are: (1) The present invention uses a modular conductive plug-in assembly structure formed by six sets of data connectors on the lower side of the plug block and data interfaces in the six sets of fan-shaped grooves of the placement frame. This enables the six sets of logging sensors of different monitoring types to communicate with the data acquisition and control unit in a modular way. This eliminates the need for the integrated and fixed structure of multiple sets of logging sensors in the logging instrument. When a single set of logging sensors is damaged, it is not necessary to remove the entire multi-parameter logging device from the drill string. This avoids the waste of resources of logging sensor components and reduces the replacement and maintenance costs of logging-while-drilling equipment.

[0017] (2) The present invention utilizes the thread engagement transmission mechanism formed by the outer side thread of the rotating drum and the inner side thread structure of the lock housing to push the inclined structure of the six sets of locking tongue blocks, so that the six sets of locking tongue blocks are inserted into the rectangular groove of the plug for upper limit locking, ensuring that the data connector is stably plugged into the plug of the data interface, avoiding the data connector and data interface from being separated due to the vibration of the drill string, and preventing poor contact between the data connector and data interface from causing interruption of data transmission or signal distortion between the logging sensor and the data acquisition and control unit.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 This invention provides a multi-parameter logging-while-drilling data acquisition device for exploration, such as... Figure 1-10 As shown, it includes a bottom cover 1, a barrel shell 2, a data acquisition and control unit 3, a sleeve shell 4, and a multi-parameter logging device 5. The upper side of the bottom cover 1 is connected to the barrel shell 2 by bolts, and the data acquisition and control unit 3 is installed on the inner side of the barrel shell 2; the bottom end of the sleeve shell 4 is connected to the barrel shell 2 by bolts, and the multi-parameter logging device 5 is installed on the inner side of the sleeve shell 4.

[0022] In this embodiment, the bottom cover 1 and the barrel shell 2 work together to form a sealed protective cavity, providing a stable installation and operating space for the data acquisition and control unit 3, and isolating the complex downhole environment from interference to the core control unit; the sleeve shell 4 serves as the outer protective structure, providing an installation carrier and basic protection for the multi-parameter logging device 5, and together they constitute a complete hardware foundation for logging-while-drilling data acquisition, adapting to the drilling tool installation space and working condition requirements of drilling operations.

[0023] Example 2 Based on Example 1, this example specifically defines the multi-parameter logging device 5, which includes a logging sensor 501, a placement frame 502, a data interface 503, an insert block 504, a locking tongue block 505, a support rod 506, a tension spring 507, a rotating drum 508, a pinch plate 509, a data connector 510, and a locking housing 511. A mounting bracket 502 is installed on the outer side of the data interface 503. A sleeve shell 4 is welded to the outer side of the mounting bracket 502 near the bottom. A lock shell 511 is welded to the upper side of the mounting bracket 502. The lock shell 511 is engaged with the rotating drum 508. A pinch plate 509 is welded to the center of the top of the insertion block 504. A data connector 510 is installed at the center of the lower side of the insertion block 504. A logging sensor 501 is installed on the outer side of the insertion block 504. A tension spring 507 is nested on the outer side of the support rod 506. The mounting bracket 502 is slidably connected to the outer side of the support rod 506. A locking tongue block 505 is welded to the end of the support rod 506.

[0024] In this embodiment, the mounting frame 502 provides a unified mounting base for all components of the multi-parameter logging device 5. Through the plug-in cooperation of the data connector 510 and the data interface 503, the electrical signal conduction between the logging sensor 501 and the data acquisition and control unit 3 is realized. The locking shell 511, the rotating drum 508, the locking tongue block 505, the support rod 506 and the tension spring 507 cooperate to form a linkage locking mechanism, which can quickly lock and unlock the plug block 504. The pinch plate 509 provides the operator with a gripping part for plugging and unplugging the plug block 504. The whole system realizes the modular assembly and disassembly of the logging sensor 501, providing a structural basis for the independent maintenance of individual sensors in the future.

[0025] Example 3 Based on the above embodiments, this embodiment further defines the structure of the sleeve shell 4 and the insert block 504. The sleeve shell 4 is a cylindrical structure that runs vertically through the sleeve shell 4. The sleeve shell 4 is made entirely of 316L stainless steel. The multi-parameter logging device 5 is embedded inside the cylindrical structure of the sleeve shell 4. There are six sets of insert blocks 504. Each set of insert blocks 504 is a fan-shaped column structure. The fan-shaped column of the insert block 504 has a rectangular groove. A logging sensor 501 is installed on the outer side of each set of insert blocks 504. The six sets of logging sensors 501 are a temperature sensor, a vibration sensor, a neutron porosity sensor, an ultrasonic caliper sensor, an acoustic pressure sensor, and an inductive resistivity sensor.

[0026] The 316L stainless steel sleeve shell 4 possesses excellent corrosion resistance, high temperature resistance, and pressure resistance, and can withstand the impact and abrasion of downhole high temperature, high pressure, corrosive drilling fluid, and well wall rock fragments and gravel. It provides comprehensive isolation and protection for the inner multi-parameter logging device 5, ensuring the reliability of the device during long-term drilling operations. The six sets of fan-shaped columnar inserts 504 are arranged in a ring array, which can make full use of the radial space of the device. Each set of inserts 504 is equipped with an independent logging sensor 501, which can realize the synchronous comprehensive measurement of multiple parameters such as drill string vibration, formation temperature, formation porosity distribution, well diameter, formation pressure, and formation density during drilling, covering the core parameter acquisition needs of logging while drilling.

[0027] Example 4 Based on the above embodiments, this embodiment defines the mating structure between the lock housing 511 and the rotating cylinder 508. The lock housing 511 is a cylindrical structure that extends vertically. Near the bottom of the outer side of the cylindrical structure of the lock housing 511, there are six sets of rectangular through slots extending both internally and externally. These rectangular through slots are arranged in a circular array around the vertical central axis of the cylindrical structure of the lock housing 511. Each set of rectangular through slots in the lock housing 511 contains a latch block 505. The upper side of the latch block 505 has a beveled structure, and the inner side of the cylindrical structure of the lock housing 511 has a threaded structure. The rotating cylinder 508 is a cylindrical structure. The outer side of the cylindrical structure of the rotating cylinder 508 has threads, and the threads on the outer side of the rotating cylinder 508 engage with the threaded structure on the inner side of the lock housing 511.

[0028] In this embodiment, the rotating drum 508 and the lock housing 511 form a helical transmission mechanism through threaded engagement. When the rotating drum 508 is rotated, it can move up and down along the axial direction of the lock housing 511. When the rotating drum 508 moves downward, the arc-shaped structure of its bottom edge simultaneously presses the inclined structure of the six sets of locking tongue blocks 505, pushing the locking tongue blocks 505 outward along the rectangular through slot of the lock housing 511 and inserting them into the rectangular groove of the insert block 504. This forms an upper limit lock on the insert block 504, ensuring that the data connector 510 at the bottom of the insert block 504 is stably inserted into the data interface 503. This avoids the severe vibration of drilling operations causing poor contact between the data connector 510 and the data interface 503, preventing data transmission interruption or signal distortion between the logging sensor 501 and the data acquisition and control unit 3, and improving the stability of the detection data transmission. At the same time, the rotation of a single component, the rotating drum 508, can achieve the synchronous locking of the six sets of insert blocks 504, eliminating the need for individual locking operations on each set of insert blocks 504, which greatly simplifies the assembly process of the device.

[0029] Example 5 Based on the above embodiments, this embodiment further defines the structure of the pinch plate 509, the tension spring 507, and the placement frame 502. There are six sets of pinch plates 509, each set having long, raised textures densely distributed on its left and right sides. There are also six sets of tension springs 507, with a locking tongue block 505 welded to one end and a placement frame 502 welded to the other end. The outer surface of the placement frame 502 has six sets of fan-shaped grooves arranged in a circular array around its vertical central axis. Insert blocks 504 are embedded within the fan-shaped grooves of the placement frame 502. Each set of fan-shaped grooves has a circular through hole at its bottom. A data interface 503 is installed within the circular through hole of the placement frame 502. A data connector 510 is plugged into the connector 503. The data connector 510 is connected to the logging sensor 501 via a wire, and the data interface 503 is connected to the data acquisition and control unit 3 via a wire.

[0030] In this embodiment, the elongated raised texture on the surface of the pinch plate 509 can interlock with the operator's fingertips, increasing the friction between the hand and the pinch plate 509, making it easier for the operator to easily insert and remove the insert block 504 into the fan-shaped groove of the placement frame 502. The fan-shaped groove of the placement frame 502 can accurately position and guide the insert block 504, ensuring that the data connector 510 and data interface 503 are precisely connected when the insert block 504 is inserted. The six independent plug-in structures realize independent modular communication connection between the six sets of logging sensors 501 and the data acquisition and control unit 3. When a single logging sensor 501 is damaged, it is not necessary to remove the entire multi-parameter logging device 5 from the drilling site. The entire sensor is removed and replaced, avoiding the waste of resources due to undamaged sensors and reducing the replacement and maintenance costs of logging-while-drilling equipment. The tension spring 507 provides a reset force for the locking tongue block 505. When the rotating drum 508 is rotated in the opposite direction to move it upward along the internal thread of the lock housing 511 and disengage from the inclined structure of the locking tongue block 505, the six tension springs 507 pull the six locking tongue blocks 505 back into the rectangular through groove of the lock housing 511 through their own elastic force. This allows the locking tongue blocks 505 to automatically disengage from the rectangular groove of the insert block 504, realizing the synchronous and rapid unlocking of the six insert blocks 504. This greatly simplifies the unlocking process and makes the disassembly and maintenance of the device more convenient.

[0031] Example 6 This embodiment provides a method for acquiring multi-parameter logging-while-drilling data for exploration, which is implemented using the multi-parameter logging-while-drilling data acquisition device for exploration provided in the above embodiment, and includes the following steps: S1, the plug 504 carrying the logging sensor 501 is inserted into the fan-shaped groove of the placement frame 502, so that the data connector 510 at the bottom of the plug 504 is precisely connected to the data interface 503 in the groove, and the communication connection between the logging sensor 501 and the data acquisition and control unit 3 is completed. S2, rotate the rotating drum 508, and drive the locking tongue block 505 to extend and engage with the rectangular groove of the insertion block 504 through the threaded engagement of the rotating drum 508 and the lock housing 511, thereby locking the insertion block 504 and ensuring the connection stability of the data connector 510 and the data interface 503. S3, during the drilling operation, six sets of logging sensors 501 collect corresponding formation and drill string parameters in real time. The collected electrical signal data is transmitted to the data acquisition and control unit 3 via data connector 510 and data interface 503. The data acquisition and control unit 3 completes the acquisition and integration processing of multi-parameter logging data. Working principle: First, the mechanical assembly and electrical signal conduction of the sensor module are completed. Then, the module is fixed by a locking mechanism to prevent drilling vibration from causing the connection to loosen, ensuring the stability of data transmission. During the drilling process, multiple independent sensors synchronously collect downhole multi-dimensional parameters. The electrical signals are stably transmitted to the core control unit through a modular plug-in structure, realizing real-time, continuous, and multi-dimensional acquisition of formation parameters during the drilling process. Logging operations can be completed without stopping drilling, greatly improving the efficiency of drilling exploration.

[0032] Example 7 Based on Example 6, this example provides an independent replacement method for a damaged logging sensor 501. The specific steps are as follows: When one or more sets of logging sensors 501 are damaged, the operator rotates the rotating drum 508 in the reverse direction, causing the rotating drum 508 to move upward along the internal thread of the lock housing 511, disengaging from the inclined structure of the locking tongue block 505. The six sets of tension springs 507 simultaneously drive the locking tongue block 505 back into the through groove of the lock housing 511 through elastic tension, releasing the lock on the insert block 504. The operator uses the pinch plate 509 to pull out the corresponding insert block 504 carrying the damaged logging sensor 501 from the fan-shaped groove of the placement frame 502. After replacing it with a new insert block 504 carrying a good logging sensor 501, the steps S1-S2 in Example 6 are repeated to complete the independent replacement of the damaged logging sensor 501.

[0033] When rotating the drum 508 to lock the insert 504, the drum 508 rotates downward along the internal thread of the lock housing 511, simultaneously pushing the inclined structure of the six sets of locking tongue blocks 505, so that the six sets of locking tongue blocks 505 are simultaneously inserted into the rectangular grooves of the corresponding insert 504, thus completing the synchronous locking of the six sets of insert 504; when rotating the drum 508 in the opposite direction to unlock, the drum 508 moves upward along the internal thread of the lock housing 511 to disengage from the locking tongue blocks 505, and the six sets of tension springs 507 synchronously drive the six sets of locking tongue blocks 505 to retract through elastic tension, thus completing the synchronous unlocking of the six sets of insert 504.
