Description

Technical Field

[0001] This invention belongs to the field of oil well logging cuttings analysis, and specifically relates to a small-scale rapid cuttings storage device and its operation method, used for cuttings collection, transportation and storage. Background Technology

[0002] Existing cuttings collection, conveying, and storage devices have the following drawbacks: First, the single-bag cuttings storage and conveying cycle is long, failing to meet the high real-time requirements of cuttings storage cycles during rapid drilling operations at the well site; second, the number of cuttings storage boxes is small, and cuttings are collected blindly without real-time monitoring of cuttings weight, making it impossible to adaptively adjust the entire cuttings sampling process based on real-time storage volume using sampling algorithms; third, the overall device is large, making it difficult to find a suitable installation location under harsh field conditions; fourth, the overall device has a complex design, resulting in low reliability during long-term operation in harsh field environments; and fifth, there is no real-time monitoring function, making it impossible to dynamically adjust each action. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a small-scale rapid rock cuttings storage device for drilling sites and its operation method.

[0004] The present invention adopts the following technical solution:

[0005] An improved small-scale rock cuttings rapid storage device includes a storage conveyor frame. A collector limiting device is installed at each end of the frame, allowing the collectors to be inserted into and removed when needed. Several rock cuttings boxes can be stacked and inserted into the collectors, and removed when needed. Ultrasonic direct detection sensors are installed at the bottom of the storage conveyor frame and the two collectors, respectively. A limiting guide rail for the rock cuttings boxes to pass through is provided between the two collectors on the storage conveyor frame. A corrugated pipe load cell and a card reader are sequentially installed, with the corrugated pipe load cell directly above the receiving position. A lifting push rod is installed at the bottom of the collector adjacent to the card reader, and a corresponding clamping push rod is installed at the top. A guide rod cylinder is installed at the rear of the collector adjacent to the corrugated pipe load cell. When the cylinder rod of the guide rod cylinder extends, it pushes the rock cuttings box from the adjacent collector onto the corrugated pipe load cell.

[0006] Furthermore, a spring-damped shock absorber is installed at each of the four bottom corners of the storage and transmission chassis frame.

[0007] Furthermore, an aviation socket for receiving external electrical control signals is installed on the storage and transmission chassis frame.

[0008] Furthermore, a cable tray is provided on the frame of the storage and transmission chassis to accommodate the internal pipelines of the device.

[0009] Furthermore, a tray is installed at the bottom of the collector, which can hold 10 rock cutting boxes.

[0010] Furthermore, the rock cuttings box includes a box body, with an identification tag installed at the bottom of the box body.

[0011] Furthermore, the limit guides consist of two opposing rails.

[0012] Furthermore, the lifting push rod, the holding push rod, and the guide rod cylinder are all pneumatic.

[0013] Furthermore, position sensors are installed on the lifting push rod and guide rod cylinder.

[0014] An operating method applicable to the aforementioned small-scale rapid rock cuttings storage device, with the following improvement:

[0015] Place the first collector filled with empty rock cuttings into the collector limiting device adjacent to the guide rod cylinder, and place the second collector without rock cuttings into the collector limiting device opposite to the lifting push rod.

[0016] After the work begins, the cylinder rod of the guide rod cylinder extends, pushing the first rock cutting box at the bottom of the first collector out of the first collector and onto the bellows weighing sensor. The remaining rock cutting boxes in the first collector fall down in sequence, causing the second rock cutting box to fall to the bottom of the first collector.

[0017] When the bellows weighing sensor detects that the first rock cutting box above it has received the set amount of rock cuttings, the cylinder rod of the guide rod cylinder extends again, pushing the second rock cutting box at the bottom of the first collecting box out of the first collecting box and onto the bellows weighing sensor. At the same time, the second rock cutting box pushes the first rock cutting box onto the card reader along the limit guide rail. The card reader reads the identification tag of the first rock cutting box and uploads the read identification code to the host computer. The host computer then matches the identification code with the rock cuttings contained in the first rock cutting box. The remaining rock cutting boxes in the first collecting box fall in sequence, causing the third rock cutting box to fall to the bottom of the first collecting box.

[0018] When the bellows weighing sensor detects that the second rock cuttings box above it has received the set amount of rock cuttings, the cylinder rod of the guide rod cylinder extends again, pushing the third rock cuttings box at the bottom of the first collecting box out of the first collecting box and onto the bellows weighing sensor. At the same time, the third rock cuttings box pushes the second rock cuttings box onto the card reader along the limit guide rail. The second rock cuttings box pushes the first rock cuttings box onto the lifting push rod at the bottom of the second collecting box along the limit guide rail. The card reader reads the identification tag of the second rock cuttings box and uploads the read identification code to the host computer. The host computer matches the identification code with the rock cuttings in the second rock cuttings box. The lifting push rod extends to raise the first rock cuttings box. The corresponding holding push rod extends in opposite directions to hold the first rock cuttings box in the air. After the lifting push rod retracts, the remaining rock cuttings boxes in the first collecting box fall down in sequence, causing the fourth rock cuttings box to fall to the bottom of the first collecting box.

[0019] When the bellows load cell detects that the third cuttings box above it has received the set amount of cuttings, the cylinder rod of the guide rod cylinder extends again, pushing the fourth cuttings box at the bottom of the first collector out of the first collector and onto the bellows load cell. At the same time, the fourth cuttings box pushes the third cuttings box onto the card reader along the limit guide rail. The third cuttings box then pushes the second cuttings box onto the lifting push rod at the bottom of the second collector along the limit guide rail. The card reader then reads the identification tag of the third cuttings box. The read identification code is uploaded to the host computer, which then matches the identification code with the rock cuttings in the third rock cuttings box. The corresponding support push rod retracts, and the first rock cuttings box falls onto the second rock cuttings box. The lifting push rod extends to raise the second rock cuttings box and the first rock cuttings box on top of it. The corresponding support push rods extend in opposite directions to support the first and second rock cuttings boxes in the air. Then the lifting push rod retracts, and the remaining rock cuttings boxes in the first collector fall down in sequence, causing the fifth rock cuttings box to fall to the bottom of the first collector.

[0020] This cycle continues until the last rock cuttings box in the first collector is ejected. Then, the ultrasonic direct detection sensor at the bottom of the first collector sends a signal to the host computer that the first collector is empty.

[0021] The beneficial effects of this invention are:

[0022] The small-scale rapid cuttings storage device disclosed in this invention adopts a frame structure, making it compact, lightweight, and easy to transport and install on-site. It is adaptable to most installation environments and provides strong support for cuttings analysis in oil well logging. The three-dimensional space storage structure reduces the device's volume while allowing for a larger cuttings box storage capacity. The lifting push rod, clamping push rod, and guide rod cylinder are all pneumatic components. Pneumatic drive offers high safety and is a low-cost, high-reliability explosion-proof solution that meets the safety requirements of field applications.

[0023] The operating method disclosed in this invention, in conjunction with the small-scale rapid rock cuttings storage device disclosed in this invention, completes the rapid transport and storage of rock cuttings. It can automatically and quickly correlate collected rock cuttings with well depth, and control the rock cuttings sampling volume in real time and with precision. The entire process of rock cuttings transport and storage is monitored in real time by sensors, allowing for dynamic adjustments to the entire workflow, thus improving the reliability and stability of the system operation.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] Example 1, such as Figure 1As shown in Figure 3, this embodiment discloses a small-scale rapid rock cuttings storage device, which is installed at the discharge port of a rock cuttings collection device. It includes a storage conveyor box 1, which includes a storage conveyor box frame 101. A collector limiting device 102 is installed at each end of the storage conveyor box frame. The collector 3 can be inserted into the collector limiting device and removed when needed. Several rock cuttings boxes 6 can be inserted into the collector in a stacked manner and removed when needed. Ultrasonic direct detection sensors 103 are installed at the bottom of the storage conveyor box frame and the bottom of the two collectors, respectively. The ultrasonic direct detection sensors can detect whether the collector is placed in the storage conveyor box and whether the collector contains rock cuttings boxes. Two opposing guide rails 110 and 111 are installed between the two collectors on the storage and conveyor frame to allow the rock cuttings boxes to pass through. A bellows load cell 107 and a card reader 106 are installed sequentially. The bellows load cell is positioned directly above the material receiving position to detect the amount of material received by the rock cuttings box, thereby monitoring the entire rock cuttings receiving process in real time and adjusting the working status according to the rock cuttings receiving situation. A lifting push rod 105 is installed at the bottom of the collector adjacent to the card reader, and a corresponding clamping push rod 104 is installed at the top. A guide rod cylinder 109 is installed at the rear of the collector adjacent to the bellows load cell. When the cylinder rod of the guide rod cylinder extends, it can push the rock cuttings box from the adjacent collector onto the bellows load cell.

[0032] In this embodiment, a spring-damped shock absorber 2 is installed at each of the four corners of the bottom of the storage and conveyor chassis frame to improve the operational stability of the device and reduce the impact of environmental vibration on the device. Aviation sockets 4 and 5 for receiving external electrical control signals are provided on the storage and conveyor chassis frame. Cable trays 108 are provided on the storage and conveyor chassis frame to accommodate the internal pipelines, with the pipelines neatly arranged within the trays. A support plate is provided at the bottom of the collector to prevent the rock cuttings boxes from falling after being placed inside. The collector can hold 10 rock cuttings boxes, and can be lifted by hand to transport the box along with the 10 rock cuttings boxes.

[0033] As shown in Figures 4(a) and 4(b), the cuttings box includes a box body 601, with an identification tag 602 embedded in the bottom of the box body to facilitate automatic and rapid matching of the cuttings box with the well depth. Ultrasonic sensors installed on both sides of the cuttings box can realize real-time monitoring of the sampling unit position, ensuring the reliability of system operation.

[0034] The lifting push rod, the clamping push rod, and the guide rod cylinder are all pneumatic, and position sensors are installed on the lifting push rod and the guide rod cylinder. The position sensors enable real-time monitoring of the entire working status, ensuring the stability of system operation and providing data support for dynamic adjustments.

[0035] This embodiment also discloses an operating method applicable to the aforementioned small-scale rapid rock cuttings storage device:

[0036] Place the first collector filled with empty rock cuttings into the collector limiting device adjacent to the guide rod cylinder, and place the second collector without rock cuttings into the collector limiting device opposite to the lifting push rod.

[0037] After the work begins, the transmission command is issued, the cylinder rod of the guide rod cylinder extends, and pushes the first rock cutting box at the bottom of the first collector out of the first collector and onto the bellows weighing sensor. The remaining rock cutting boxes in the first collector fall down in sequence, causing the second rock cutting box to fall to the bottom of the first collector.

[0038] When the bellows weighing sensor detects that the first rock cutting box above it has received the set amount of rock cuttings, the cylinder rod of the guide rod cylinder extends again, pushing the second rock cutting box at the bottom of the first collecting box out of the first collecting box and onto the bellows weighing sensor. At the same time, the second rock cutting box pushes the first rock cutting box onto the card reader along the limit guide rail. The card reader reads the identification tag of the first rock cutting box and uploads the read identification code to the host computer software system. The host computer then associates the identification code with the depth of the rock cuttings in the first rock cutting box. The remaining rock cutting boxes in the first collecting box fall in sequence, causing the third rock cutting box to fall to the bottom of the first collecting box.

[0039] When the bellows weighing sensor detects that the second rock cuttings box above it has received the set amount of rock cuttings, the cylinder rod of the guide rod cylinder extends again, pushing the third rock cuttings box at the bottom of the first collecting box out of the first collecting box and onto the bellows weighing sensor. At the same time, the third rock cuttings box pushes the second rock cuttings box onto the card reader along the limit guide rail. The second rock cuttings box pushes the first rock cuttings box onto the lifting push rod at the bottom of the second collecting box along the limit guide rail. The card reader reads the identification tag of the second rock cuttings box and uploads the read identification code to the host computer software system. The host computer associates the identification code with the depth of rock cuttings in the second rock cuttings box. The lifting push rod extends to raise the first rock cuttings box. The corresponding holding push rod extends in opposite directions to hold the first rock cuttings box in the air. After the lifting push rod retracts, the remaining rock cuttings boxes in the first collecting box fall down in sequence, causing the fourth rock cuttings box to fall to the bottom of the first collecting box.

[0040] When the bellows load cell detects that the third cuttings box above it has received the set amount of cuttings, the cylinder rod of the guide rod cylinder extends again, pushing the fourth cuttings box at the bottom of the first collector out of the first collector and onto the bellows load cell. Simultaneously, the fourth cuttings box pushes the third cuttings box onto the card reader along the limit guide rail. The third cuttings box then pushes the second cuttings box onto the lifting push rod at the bottom of the second collector along the limit guide rail. The card reader reads the identification tag of the third cuttings box and displays the information... The identification code is uploaded to the host computer software system, which then associates the identification code with the depth of the rock cuttings in the third rock cuttings box. The corresponding support push rod retracts, and the first rock cuttings box falls onto the second rock cuttings box. The lifting push rod extends to raise the second rock cuttings box and the first rock cuttings box on top of it. The corresponding support push rods extend in opposite directions to support the first and second rock cuttings boxes in the air. Then the lifting push rod retracts, and the remaining rock cuttings boxes in the first box collector fall down in sequence, causing the fifth rock cuttings box to fall to the bottom of the first box collector.

[0041] This cycle continues until the last cuttings box in the first collector is ejected. At this point, the ultrasonic direct detection sensor at the bottom of the first collector sends a signal to the host computer software system indicating that the first collector is empty. The user can then remove both the full and empty collectors simultaneously, replace them with new ones, and continue the cycle.
