Description

Technical Field

[0001] This utility model relates to the field of cuttings treatment technology, and in particular to a cuttings treatment device for oil and gas drilling. Background Technology

[0002] Oil and gas drilling cuttings are rock fragments and particles returned to the surface after the drill bit breaks up the formation rock during oil and gas drilling. During drilling, the drill bit rotates and cuts through the formation; the broken rock is carried upwards along the wellbore by drilling fluid and eventually discharged at the wellhead. These discharged rock fragments form drilling cuttings. Drill cuttings vary greatly in size, shape, and composition, ranging from micrometer-sized fine particles to several-centimeter-sized lumps. They are important physical data for studying underground stratigraphic structure, rock properties, and oil and gas shows, and have significant analytical and research value for oil and gas exploration and development. When drilling cuttings reach the surface, they adhere to oily wastewater, which can pollute the environment. Direct discharge or improper treatment can cause serious pollution to soil and water bodies, affecting ecological balance and the lives of surrounding residents. Treatment equipment is needed to process the drilling cuttings. However, existing treatment equipment typically uses heating to separate oil and water. During use, the accumulation of drilling cuttings leads to uneven heating, affecting the efficiency of oil-water separation and resulting in poor treatment effects, posing certain drawbacks.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5As shown, this embodiment provides an oil and gas drilling cuttings processing device, including a processing box 1. A vibrating screen filter plate 2 is slidably inserted into the processing box 1. Reciprocating pushing components 3 are installed on the outer walls at both ends of the processing box 1, and the reciprocating pushing components 3 are closely connected to the two ends of the vibrating screen filter plate 2. A steam heating nozzle 4 is fixedly inserted into the processing box 1, and the steam heating nozzle 4 is located below the vibrating screen filter plate 2. An installation block 5 is fixedly installed on the outer wall of the processing box 1. A limiting groove is opened on the installation block 5, and a distance adjustment component 6 is installed in the limiting groove. A first crushing roller 7 and a second crushing roller 8 are installed on the distance adjustment component 6. The first crushing roller 7 and the second crushing roller 8 are located below the feeding port opened on the processing box 1. A slag discharge filter component 9 is installed in the processing box 1, and the slag discharge filter component 9 is located below the vibrating screen filter plate 2. In use, the cuttings are fed into the processing box 1 through the feeding port. The cuttings fall between the first crushing roller 7 and the second crushing roller 8. The distance between the two rollers is adjusted by the distance adjustment component 6 to achieve preliminary crushing. The crushed rock fragments fall onto the vibrating screen filter plate 2. The reciprocating push assembly 3 drives the vibrating screen filter plate 2 to vibrate and screen, separating particles of different sizes. Steam is sprayed from the steam heating nozzle 4 to heat the rock fragments and promote oil-water separation. The screened rock fragments are further filtered through the slag discharge filter assembly 9, finally separating solid residues and liquid components, completing the rock fragment processing.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the reciprocating push assembly 3 includes a positioning mounting plate 301 and an L-shaped mounting plate 302. The positioning mounting plate 301 is fixed to one end of the processing box 1, and the L-shaped mounting plate 302 is fixed to the other end of the processing box 1. A drive motor 303 is fixedly mounted on the positioning mounting plate 301. A first drive column 304 and a second drive column 305 are rotatably mounted on the positioning mounting plate 301. One end of the first drive column 304 is fixedly connected to the output shaft of the drive motor 303. Pushing protrusions 306 are fixedly mounted on both the first drive column 304 and the second drive column 305. The pushing protrusions 306 are in contact with one end of the vibrating screen filter plate 2. The first drive column 304 and the second drive column 305 are connected by a synchronous belt 307. The other end of the vibrating screen filter plate 2 is elastically connected to the L-shaped mounting plate 302 by a return spring 308. In use, the drive motor 303 is started, which drives the first drive column 304 to rotate, and the second drive column 305 rotates synchronously through the synchronous belt 307. The pushing protrusions 306 on the first drive column 304 and the second drive column 305 periodically push one end of the vibrating screen filter plate 2 as it rotates, causing it to slide along the inner wall of the processing box 1. The other end of the vibrating screen filter plate 2 is elastically connected to the L-shaped mounting plate 302 via a return spring 308. When the pushing protrusion 306 disengages, the return spring 308 returns the vibrating screen filter plate 2 to its original position, forming a reciprocating motion. The vibration of the vibrating screen filter plate 2 ensures that the rock chips are evenly distributed during the screening process, improving screening efficiency and increasing the heating and separation efficiency of oil and water.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the distance adjustment component 6 includes a servo motor 601 and a bidirectional lead screw 602. The servo motor 601 is fixed on the inner wall of one end of the limiting slide groove, and the bidirectional lead screw 602 is rotatably mounted on the inner wall of the other end of the limiting slide groove through a rotating joint 603. One end of the bidirectional lead screw 602 is fixedly connected to the output shaft of the servo motor 601. A threaded slider 604 is installed on the bidirectional lead screw 602. The threaded slider 604 is slidably engaged in the limiting slide groove, and there are two threaded sliders 604. The two threaded sliders 604 are located at the opposite thread ends of the bidirectional lead screw 602. One end of the first crushing roller 7 and the second crushing roller 8 are fixedly connected to the built-in motor output shafts of the two threaded sliders 604. In use, the servo motor 601 is started to drive the bidirectional lead screw 602 to rotate. Since the thread directions at both ends of the bidirectional lead screw 602 are opposite, the two threaded sliders 604 move towards or in opposite directions in the limiting slide groove, thereby adjusting the distance between the first crushing roller 7 and the second crushing roller 8. Based on the hardness and particle size of the rock chips, the distance between the two rollers is precisely controlled by a servo motor 601 to ensure crushing effect. This allows for flexible adaptation to different working conditions, improving crushing efficiency and equipment adaptability. The threaded slider 604 has a built-in motor that drives the first crushing roller 7 and the second crushing roller 8 to rotate, compressing and crushing the rock chips entering from the feed inlet. The crushed rock chips fall onto the vibrating screen filter plate 2 for further processing.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 3 As shown, the slag discharge filter assembly 9 includes an extension seat 901, which is fixed to the outer wall of the processing box 1. A rotary drive rod 902 and a stepper motor 903 are mounted on the extension seat 901. One end of the rotary drive rod 902 is fixedly connected to the output shaft of the stepper motor 903. A perforated conveyor belt 904 is wound around the rotary drive rod 902 and is located inside the processing box 1. In use, the stepper motor 903 is started, driving the rotary drive rod 902 to rotate, causing the perforated conveyor belt 904 to circulate within the processing box 1. The screened rock debris falls into the perforated conveyor belt 904, and the liquid component is filtered out through the perforations, achieving solid-liquid separation. The stepper motor 903 can adjust the conveyor belt speed to control the slag discharge efficiency. The separated slag moves with the conveyor belt to the outside of the processing box 1, completing the slag discharge process.
