Description

Technical Field

[0001] The invention belongs to the technical field of petroleum engineering equipment and relates to a pipe column processing device. Background Art

[0002] In the oil drilling industry, field operations suffer from low automation levels and high labor intensity. Domestic drilling companies are promoting the use of more efficient and advanced automated drilling rigs. During multi-device automated operations, drilling tools are continuously transferred between multiple devices, requiring solutions for temporary storage, alignment, and thread cleaning. Currently, manufacturers use mouseholes for temporary tool storage without integrating other functions.

[0003] To address issues such as low automation levels and high labor intensity at oil drilling sites, the domestic oil industry has begun promoting more efficient, advanced, and safer automated drilling rigs. These rigs are evolving from single-device automation to multi-device automation. When establishing a drill string or dropping drill pipe with multiple devices, drill string transfers between devices are necessary. Furthermore, during the establishment process, storage requirements for single drill strings, two single strings per column, and three single strings per column are required. During tripping, drill string transfers must be continuously performed, requiring thread cleaning. Currently, only string storage devices are available, but there are no dedicated devices for transferring and cleaning the string between devices. Summary of the Invention

DETAILED DESCRIPTION

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The pipe column processing device of the present invention is as follows: Figure 1 As shown, it includes a storage cylinder 4, with a guide mechanism 1 provided at the top of the storage cylinder 4. A high-pressure cleaning mechanism 2 is provided between the guide mechanism 1 and the storage cylinder 4. A centering mechanism 3 is provided inside the storage cylinder 4, and the centering mechanism 3 is located near the top of the storage cylinder 4. The storage cylinder 4 also has a positioning adjustment mechanism 5, and the positioning adjustment mechanism 5 is located near the bottom of the storage cylinder 4. The bottom of the storage cylinder 4 is connected to a waste treatment mechanism 6. The guide mechanism 1 is in an inverted cone shape, and an inner ring is provided inside the guide mechanism 1. The bottom end of the guide mechanism 1 is inserted into the high-pressure cleaning mechanism 2, and the high-pressure cleaning mechanism 2 is connected to the storage cylinder 4. Figure 2 As shown, the high-pressure cleaning mechanism 2 includes a high-pressure water delivery mechanism 8, which is connected to a water tank 9, which is connected to a spray mechanism 10. The spray mechanism 10 is annular, with a nozzle disposed inside the spray mechanism 10, and a rotating mechanism 7 is provided on the side wall of the spray mechanism 10. The centering mechanism 3 is hourglass-shaped, and the center of the centering mechanism 3 coincides with the center of the storage cylinder 4. The centering mechanism 3 is clamped to the inner wall of the storage cylinder 4. Figure 3 As shown, the positioning adjustment mechanism 5 includes a fixed seat 13, which is set on the inner wall of the storage tube 4, and a flow channel is set between the fixed seat 13 and the storage tube 4. The fixed seat 13 is provided with a power mechanism 11, and the top of the main shaft of the power mechanism 11 is fixedly connected to the load-bearing plate 12. A guide plate is provided on the fixed seat 13, and a guide block is provided on the side wall of the load-bearing plate 12. The guide block is clamped on the guide plate, and an anti-recoil plate is provided on the top of the guide plate. Figure 4 As shown, the waste treatment mechanism 6 includes a valve 14, which is connected to the bottom of the storage cylinder 4. The valve 14 is connected to a waste collection box 15 through a pipeline. The waste collection box 15 is provided with a waste neutralization mechanism 16, which can put a box cleaner or a neutralizer into the waste collection box 15.

[0020] In the pipe string processing device of the present invention, the guide mechanism 1 on the upper part of the storage cylinder 4 is a detachable conical structure with various specifications suitable for different drilling tools. It is fixed on the upper part of the high-pressure cleaning mechanism 2. The drilling tool is quickly guided into the storage cylinder 4 through the guide structure 1 at high speed.

[0021] The high-pressure cleaning mechanism 2 uses electricity, liquid, gas or the like as a power source, and cleans the drill thread by spraying clean water or steam at high pressure when the drill thread extends into the high-pressure cleaning device.

[0022] The centering device 3 is an adaptive drilling tool structure, which is installed inside the storage tube 4 and is detachable. It can automatically maintain the centering state after drilling tools of different specifications are inserted into the storage tube, making it convenient for other equipment to grab the drilling tools.

[0023] The lower portion of the storage barrel 4 is equipped with a positioning adjustment mechanism 5, which allows manual or hydraulic adjustment of the height of the drill tool extending from the storage barrel to meet the requirements of automated operation of drill tools of different lengths. The positioning adjustment mechanism 5 is equipped with a locking mechanism to prevent retreat. The sewage treatment mechanism 6 is connected to the sewage pipeline to collect and treat the cleaning wastewater.

[0024] The top of the tubular string handling device of the present invention features a removable guide mechanism 1. When other tubular string equipment delivers drill tools to the storage barrel 4 for storage, the tools may initially wobble and be difficult to precisely position. The guide mechanism 1 allows for rapid positioning and insertion of the drill tools. Furthermore, the guide mechanism 1 contains a removable inner ring, allowing for quick replacement to accommodate drill tools of varying specifications. The entire guide mechanism 1 is also removable, making it easy to remove and remove for repair and maintenance of the inner ring surface.

[0025] The lower part of the guide mechanism is a high-pressure cleaning device that can clean the drill thread, including a rotating mechanism 7, a high-pressure water delivery mechanism 8, a water tank 9, and a jet mechanism 10. The high-pressure water delivery mechanism 8 is installed in the drilling platform area, and the cleaning water is pressurized by a pressure pump and then connected to the jet port through a pipeline. The water tank 3 is equipped with diesel heating, which can quickly heat the cleaning water in winter or cold areas to increase the cleaning degree. The rotating mechanism 7 is hydraulically or electrically powered and is activated when the jet mechanism 10 performs high-pressure cleaning, driving the jet mechanism 10 to rotate 360 ​​degrees, performing all-round cleaning of the drill thread to ensure the cleanliness of the thread. The jet port of the jet mechanism 10 is internal, and it sprays high-pressure water to clean the drill thread.

[0026] The lower side of the high-pressure cleaning device is the centering mechanism 3. After the drill tool is inserted into the multifunctional tubing processing device, it needs to be kept in the center of the circle in the storage tube. When other tubing equipment is used to grab the drill tool, there is no need to adjust the state and angle of the equipment's grabbing parts. The centering mechanism 3 adopts an adaptive design with a quick-install structure. It is installed by inserting the entire unit into the storage tube. Through strict calculation and design, it is ensured that the centering mechanism 3 can automatically keep the drill tool in the center of the storage tube when drill tools of different specifications and weights are inserted. The centering mechanism 3 has a stress release structure. When the drill tool is inserted and removed, it can undergo a certain degree of elastic deformation and overall deformation in the storage tube to prevent the centering mechanism 3 from getting stuck due to the inability to release stress.

[0027] The lower side of the centering device is a positioning and adjustment device. Because the lengths of different drill tools are inconsistent, in order to ensure that the height of the drill tool protrudes from the multifunctional pipe processing device, this device is used to automatically adjust the height of the drill tool to meet the equipment range requirements for grabbing the drill tool. The positioning and adjustment mechanism 5 includes a power mechanism 11, a load-bearing plate 12 and a fixed seat 13, which are powered by hydraulic or electric power. The power mechanism 11 includes a hydraulic cylinder or an electric cylinder, which is mainly used as output power. The load-bearing plate 12 is equipped with a guide block, a load-bearing plate and an anti-recoil plate. By starting the power mechanism 11, the load-bearing plate 12 can move up and down in the storage tube, while bearing the weight of the drill tool and preventing the guide block from exiting the storage tube, which is safe and efficient. The fixed seat 13 is a fixed seat for installing the power mechanism 11 and the load-bearing plate 12, and bears the overall force.

[0028] At the bottom is the waste treatment mechanism 6, which collects, stores, and processes cleaned waste. The wastewater collection device consists of a pipeline and valve 14, a waste collection tank 15, and a waste neutralization mechanism 16. The wastewater inside the tubing treatment device of the present invention flows down the storage tube 4, which has a pipeline connection and a detachable reducer at the bottom. The wastewater enters the waste collection tank 15 through the pipeline and valve 14. After long-term use, the pipeline and valve 14 can be removed to clean the interior of the storage tube. When the wastewater collection tank 15 stores wastewater to a certain volume, detergents, neutralizers, and other substances are added through the waste neutralization mechanism 16 to neutralize the wastewater. Once the wastewater meets the discharge standard, the treated water is pumped out to a dedicated storage tank.

[0029] The pipe string processing device of the present invention embodies the characteristics of high multi-functional integration, high degree of automation and strong adaptability during use. It can meet multiple requirements such as storage of drill strings in automated operations, drill tool centering, drill tool thread cleaning, drill tool height adjustment, and solve functions such as drill tool cleaning during drilling.

[0030] The pipe string handling device of this invention features drill tool thread storage and cleaning. It also incorporates drill tool alignment functions, allowing rapid insertion of drill tools into a storage cartridge and preserving their alignment, meeting the requirements of automated drilling operations. Its high level of functional integration includes storage, drill tool alignment, drill tool thread cleaning, drill tool height adjustment, and a waste collection device, meeting the needs of various operating conditions. It also offers strong adaptability, adapting to various drilling tool specifications by replacing guide seats of varying diameters and positioning adjustment devices.
