Description

TECHNICAL FIELD

[0001] The utility model relates to rock breaking experiment technical field, concretely is a high pressure water jet rock breaking experiment device. BACKGROUND

On the one hand, oil and gas fields are in the late stage of exploitation, and the task of stable production is difficult, low permeability, low flow rate, and large proportion of oil and gas reservoir reserves. The conventional exploitation method consumes manpower and costs high; on the other hand, high pressure water jet technology can use high speed drilling fluid to impact the bottom of the well, assist the drill bit to break the rock, and the high speed drilling fluid can quickly clean the rock debris and improve the cleanliness of the bottom of the well.

[0003] The high pressure water jet rock breaking experiment device can effectively adjust the jetting distance of the rock sample and the jet nozzle by the lifting of the lifting drive assembly, which is convenient to operate and has high reliability. By adjusting the jetting distance between the rock sample and the jet nozzle, the influence of the rock breaking distance on the rock breaking effect can be effectively simulated, thereby providing a basis for selecting different rock sample jet distances in actual drilling process. The traditional high pressure water jet rock breaking experiment device is not convenient for fixing the experimental object on the clamping frame, which can easily cause the experimental object to shake during rock breaking simulation, affecting the experimental effect. The traditional high pressure water jet rock breaking experiment device can only adjust the distance, and cannot adjust the vertical angle and horizontal angle, which can easily cause large limitations during the experiment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figures 1-2 The diagram shows a high-pressure water jet rock-breaking experimental device, including a base 1, a support column 2 fixedly installed at the bottom of the base 1, a support platform 3 fixedly installed on the outside of the base 1, a motor 4 fixedly installed on the top of the support platform 3, a lead screw 5 fixedly installed on the output shaft of the motor 4, a slide rail 6 fixedly installed on the top of the base 1, a movable plate 7 provided on the outside of the slide rail 6, a sliding rod 8 fixedly installed on the top of the movable plate 7, a top plate 9 slidably connected to the top of the sliding rod 8, a second motor 10 fixedly installed on the top of the movable plate 7, a positioning component 11 fixedly installed on the top of the top plate 9, and a fixing component 12 fixedly installed on the top of the base 1.

[0021] Please see Figure 4 The positioning component 11 shown in the figure includes a side plate 1101, a fixed plate 1102, a rotating block 1103, a water jet gun 1104, an automatic telescopic rod 1105, a connecting pipe 1106, a power pump 1107, and a positioning frame 1108. The fixed plate 1102 is fixedly installed on the outside of the side plate 1101. The rotating block 1103 is rotatably installed on the outside of the fixed plate 1102. The water jet gun 1104 is fixedly installed on the outside of the rotating block 1103. The automatic telescopic rod 1105 is fixedly installed on the outside of the water jet gun 1104. The connecting pipe 1106 is provided on the outside of the water jet gun 1104. The power pump 1107 is fixedly installed at the other end of the connecting pipe 1106. The positioning frame 1108 is fixedly installed at the bottom of the power pump 1107. The automatic telescopic rod 1105 is fixedly installed on the top plate 9. The automatic telescopic rod 1105 is located at the other end of the water jet gun 1104 away from the side plate 1101.

[0022] In this embodiment: the positioning component 11 enables the automatic telescopic rod 1105 to extend and retract vertically, which not only pushes the water jet gun 1104 to change its angle and improves the diversity of experiments, but also provides a fixed support for the water jet gun 1104, thereby improving the stability of the experiment.

[0023] Working principle: The positioning component 11 allows the automatic telescopic rod 1105 to extend and retract vertically, not only changing the angle of the water jet gun 1104 to enhance experimental versatility but also providing fixed support for the water jet gun 1104, thus improving experimental stability. The sliding rod 8 allows horizontal movement by activating motor 10, which rotates the top plate 9. The sliding rod 8 also provides support and improves the smoothness of rotation. The moving plate 7 and lead screw 5 allow horizontal displacement of the moving plate 7 by activating motor 4 during experiments, simulating rock-breaking speeds at different distances for easy recording. The clamp 1203 and the rotating rod 1204 are designed to rotate. Rotating the rotating rod 1204 causes the threaded rod 1202 to move the clamp 1203, thus fixing the experimental material and preventing displacement during the experiment. The storage plate 1205 allows waste materials and water from the water jet gun 1104 to enter the collection box 1207 from the bottom of the storage plate 1205, collecting the waste and water and avoiding secondary cleaning. When the collection box 1207 is inside the storage box 1201, the rotating rod 1204 can limit its movement, preventing it from falling off and affecting normal use. Example 2

[0024] Please see Figures 1-5 This embodiment further illustrates Example 1, as shown in the figures. The motor 2 10 is fixedly installed on the top plate 9, and the sliding rod 8 is slidably connected to the top plate 9. Multiple identical sliding rods 8 are provided.

[0025] In this embodiment: When moving horizontally, the sliding rod 8 can be activated by the second motor 10, which will drive the top plate 9 to rotate. At the same time, the sliding rod 8 not only provides support but also improves the smoothness of rotation.

[0026] Please see Figures 1-5 In the diagram, the movable plate 7 is threadedly connected to the lead screw 5, and the movable plate 7 is slidably connected to the slide rail 6.

[0027] In this embodiment: By setting the movable plate 7 and the lead screw 5, when conducting the experiment, the motor 4 can be turned on to make the lead screw 5 rotate, which can realize the horizontal displacement of the movable plate 7 in the horizontal direction, which can simulate the rock breaking speed at different distances during the experiment, and facilitate recording.

[0028] Please see Figure 5The fixed assembly 12 shown in the figure includes a storage box 1201, a threaded rod 1202, a clamp 1203, a rotating rod 1204, a storage plate 1205, a groove 1206, a collection box 1207, a fixed post 1208, and a locking block 1209. The threaded rod 1202 is threadedly connected to the outside of the storage box 1201. The clamp 1203 is fixedly installed on the outside of the threaded rod 1202. The rotating rod 1204 is fixedly installed on the outside of the threaded rod 1202. The storage plate 1205 is fixedly installed inside the storage box 1201. The interior of storage box 1205 has multiple grooves 1206. A collection box 1207 is inserted and installed inside the storage box 1201. A fixing post 1208 is fixedly installed on the outside of the storage box 1201. A locking block 1209 is rotatably installed on the outside of the fixing post 1208. The clamp 1203 has a "C" shaped structure. There are two identical threaded rods 1202, clamps 1203 and rotating rods 1204. The two threaded rods 1202, clamps 1203 and rotating rods 1204 are symmetrically distributed about the center line of the storage box 1201.

[0029] In this embodiment: the clamp 1203 and the rotating rod 1204 are configured to rotate the rotating rod 1204, which in turn causes the threaded rod 1202 to move the clamp 1203. This can fix the experimental object and prevent it from shifting during the experiment, thus affecting the normal experiment.

[0030] Please see Figure 5 In the figure, the storage plate 1205 is located at the bottom of the clip 1203, and multiple grooves 1206 are distributed at equal intervals.

[0031] In this embodiment: By setting up the storage plate 1205, during the experiment, the waste of the experimental material and the water resources shot out by the water jet gun 1104 can enter the collection box 1207 from the bottom of the storage plate 1205, so that the waste and water resources can be collected and secondary cleaning can be avoided.

[0032] Please see Figure 5 As shown in the figure, the rotating rod 1204 has a rectangular structure and is located on the front side of the storage box 1201.
