Description

Technical Field

[0001] The present invention belongs to the field of petroleum engineering exploration, and in particular relates to a drilling cuttings storage and transportation device and a storage and transportation method in this field. Background Art

[0002] Drilling cuttings refer to rock particles ground or crushed by the drill bit during drilling. These are carried to the surface by circulating flushing fluid from the wellbore and serve as the basis for understanding rock formation properties, oil and gas indications, and compiling geological profiles. Using cuttings to document drilling geology is called cuttings logging, commonly known as sand sampling.

[0003] Existing cuttings storage and conveying devices have a small number of storage boxes, and they all receive cuttings blindly. There is a lack of real-time monitoring of the cuttings weight, and it is impossible to dynamically adjust the entire cuttings storage process; the cuttings boxes are not marked after storage, and each box of cuttings cannot be automatically matched to the actual well depth. Manual identification and recording are still required according to the storage order, which can easily cause confusion; the cuttings are relatively large and heavy, and it is difficult to find a suitable installation location under the harsh conditions of the field well site, making it impossible to realize automatic storage and conveying of drilling cuttings. Summary of the Invention

It should be understood that the specific embodiments described herein are intended solely to illustrate the present invention and are not intended to limit the present invention. For example, in this embodiment, the RFID tag embedded in the cuttings box can be replaced with other types of identifiers, such as a barcode or QR code; the pneumatic push rod can be replaced with a push rod driven by another power source; and the conveyor belt can also be powered by pneumatic devices.

[0026] Example 1, as Figure 1-3 As shown, this embodiment discloses a drilling cuttings storage and conveying device, in which a collection box socket and a material receiving port 2 are provided on the top of the storage and conveying case 1, and the material receiving port is located in front of the collection box socket, and the drilling cuttings enter the storage and conveying case through the material receiving port, and a bracket 104 is installed in the collection box socket, and the collection box 3 is inserted from the collection box socket and placed on the above-mentioned bracket, and the cuttings boxes 8 are stacked in the collection box, and an opening is reserved on the bottom front side of the collection box for the cuttings boxes to pass through, and an opening is reserved on the bottom rear side for the following push plate to pass through, and the interior of the storage and conveying case is divided into two layers, the upper conveyor belt 103 is located below the bracket and adjacent to the bracket, and the conveyor belt is supported by two or more bearings installed on the side wall of the storage and conveying case. There are three bearings in this embodiment, which are respectively located at the two ends and the middle of the conveyor belt. The motor 110 in the storage conveyor box drives one of the bearings 114 to rotate through the synchronous belt 112, driving the top of the conveyor belt to move from back to front (i.e., the conveyor belt rotates counterclockwise). A push plate 108 is installed on the conveyor belt. The front end of the top of the conveyor belt is adjacent to the downward-slanting slide 113, and the lower end of the slide is connected to the front end of the lower rock cutting box storage groove 105. A pneumatic push rod 116 is set at the front of the rock cutting box storage groove. The pneumatic push rod has two states: extended and retracted. When extended, the rock cutting box in the rock cutting box storage groove is pushed backward along the rock cutting box storage groove.

[0027] In this embodiment, the box collector includes a shell 302 and a detachable upper cover 301 installed on the top of the shell, and a handle is installed on the upper cover; there is a bend extending into the shell on the left and right sides of the bottom of the shell, so that the empty rock cuttings box will not fall from the bottom after being placed in; the shell can accommodate 10 rock cuttings boxes, and the box collector can be lifted up by hand to take it away together with the 10 rock cuttings boxes.

[0028] As shown in FIG4(a) and FIG4(b), an RFID tag 802 is installed at the bottom of the cuttings box, and a radio frequency card reader 115 is installed at the junction of the front end of the cuttings box storage slot and the lower end of the slide.

[0029] An inductive proximity switch 101 is installed in the storage conveyor chassis to detect whether a box collector is inserted into the box collector socket;

[0030] A magnetic sensor is installed on the push plate. When the push plate pushes the cuttings box to the bottom of the receiving port, the magnetic sensor meets the Hall type proximity switch 102 in the storage conveyor box.

[0031] A weighing sensor 109 is provided below the conveyor belt just below the material receiving port and adjacent to the conveyor belt; a switch button 107 is provided at the rear end of the cuttings box storage tank.

[0032] Air path connectors 4, 5, 6 for connecting an external air source to the storage and conveying chassis and an aviation socket 7 for connecting an external electrical control signal to the storage and conveying chassis are arranged on the surface of the storage and conveying chassis.

[0033] Slideway is fixedly mounted on the inner side of the storage conveyor case top.On the bottom surface of the cuttings box storage groove, sliding ball 106 is installed. The effect of sliding ball is the frictional force that reduces the cuttings box when moving in the cuttings box storage groove.

[0034] The present embodiment also discloses a storage and conveying method, which is applicable to the above-mentioned drilling cuttings storage and conveying device: a collecting box filled with cuttings boxes is inserted into the collecting box socket on the top of the storage and conveying machine box, and the motor drives the upper part of the conveyor belt to move from the back to the front. Since the push plate is higher than the bottom of the cuttings box, the push plate on the conveyor belt pushes the bottommost cuttings box from the bottom rear opening of the collecting box to fall from the front opening to the top of the conveyor belt, and the other cuttings boxes in the collecting box fall in turn under the action of gravity. When the push plate pushes the cuttings box to the bottom of the receiving port, the push plate The magnetic sensing piece meets the Hall-type proximity switch, triggering the motor to close, causing the cuttings box to stop just below the receiving port. The weighing sensor detects the amount of cuttings received by the cuttings box above it. When the amount reaches the preset value, the motor is triggered to start. After the cuttings box is transported to the end of the front end on the conveyor belt, the cuttings box slides from the slide to the front end of the cuttings box storage tank. The push plate moves from back to front with the conveyor belt, and then continues to push the next cuttings box to receive the material, until all the cuttings boxes in the box collector are filled with cuttings and slide down from the slide to the front end of the cuttings box storage tank in sequence.

[0035] The RFID reader sequentially identifies the RFID code of each cuttings box that lands at the front of the trough. It then associates this RFID code with the cuttings arrival depth within the box and transmits it to the host computer software system. A pneumatic push rod then extends (and then retracts to await the next box), pushing each cuttings box back along the trough until the last one touches the switch at the rear of the trough, signaling to the host computer software that the trough is full. The full trough can then be removed and replaced with an empty one, before the cycle continues.
