Embodiment 1

[0042] Such as Figure 2 to Figure 4 The feeding port structure of the drilling fluid powdery bagged additives shown includes a platform body 1, a through hole 3 is opened on the platform body 1, and the bottom of the through hole 3 is used to connect with the hopper 2; each side wall of the through hole 3 is provided with The flexible part 302, the flexible part 302 of each side wall corresponds to several cams 4, the cam 4 is placed inside the table body 1, and the cam 4 is in contact with the corresponding flexible part 302, and the cam 4 is driven by the first driving device to rotate; It also includes a support 5 that is rotatably connected to the upper surface of the table body 1, a second drive device 7 for driving the support 5 to rotate, the top of the support 5 is fixedly connected to the first telescopic rod 6, and the output end of the first telescopic rod 6 is downward, and The first telescopic rod 6 can rotate to the top of the through hole 3 along with the brack...

Embodiment 2

[0054] Such as Figure 5 to Figure 7 The feed port structure of the drilling fluid powdery bagged additive shown, on the basis of Embodiment 1, also includes a groove 13 arranged on the platform body 1, and the first telescopic rod 6 can rotate to the groove along with the bracket 5 13 above. The top of the groove 13 is provided with a large and small receiving cavity 131; the bottom of the receiving cavity 131 is provided with two roller shafts 15 parallel to each other, a gap is formed between the two roller shafts 15, and the roller shaft 15 is driven by the third driving device 16. Rotate; the direction of rotation of any roller shaft 15 is from top to bottom towards the notch direction, specifically as Figure 6 indicated by the arrow in the middle. The closing mouth is located in the upper area of ​​the groove, and has a closing structure with a large top and a small bottom, so that the empty bag can be closed toward the gap at the bottom after entering the closing mou...

Embodiment 3

[0058] Such as Figure 5 to Figure 7 The difference between the feed opening structure of the drilling fluid powdery bagged additive shown in Example 2 is that the bottom of the first telescopic rod restricts the bag in a different way, specifically: the upper surface of the table body 1 is provided with a blind hole inclined downward. Hole 11, the bottom end of blind hole 11 is connected to the surface of inclined part 301, and is used to put iron sheet in blind hole 11, and the first telescopic rod 6 can be rotated to directly above blind hole 11 along with support 5; The first telescopic rod 6 The bottom end is provided with electromagnet 12. In addition, the magnetic plate 14 is also laid on the side wall of the receiving cavity 131

[0059] When this embodiment is working, every time a bag full of additives is put into the through hole, the worker puts an iron sheet into the blind hole 11. Since the bottom of the blind hole is connected to the surface of the inclined par...

Abstract

The invention discloses a feeding port structure and a feeding method of a drilling fluid powdery bagged additive. The feeding port structure comprises a table body, a support, a second driving deviceand a second telescopic rod, wherein a through hole is formed in the table body, and the bottom of the through hole is used for being connected with a hopper; flexible parts are arranged on all sidewalls of the through hole, the flexible part of each side wall corresponds to a plurality of cams, the cams are in contact with the corresponding flexible parts, and the cams are driven by a first driving device to rotate; the second driving device is used for driving the support to rotate, the top end of the support is fixedly connected with a first telescopic rod, the output end of the first telescopic rod faces downwards, and the first telescopic rod can rotate to the position above the through hole along with the support; and the second telescopic rod is fixed at the bottom of the table body, the output end of the second telescopic rod faces the direction of the through hole and is fixedly connected with a cutter, and a blade of the cutter faces the direction of the through hole. The feeding port structure and the feeding method are used for solving the problem that powder accumulated at the edge part of a material bag is difficult to automatically discharge in the prior art, and the purposes of enabling the additive to be fully discharged and avoiding the waste of the additive at the edge part are achieved.

Description

technical field [0001] The invention relates to the field of petroleum drilling, in particular to the structure of a feeding port for drilling fluid powdery bagged additives and a feeding method. Background technique [0002] Mud, that is, drilling fluid, is called "drilling blood" and is a very important part of drilling and completion engineering. In the process of drilling fluid preparation, whether it is the preparation of new mud or glue, it is necessary to add a large amount of additives. Most of the additives are bagged powders, which require workers to manually carry bags one by one to the feeding port, then manually break the bag, turn it over to the point where the hole is facing down, and dump it into the feeding port. A bag of mud material weighs dozens of kilograms, and depending on the depth of the well, the feeding amount generally ranges from tens to hundreds of bags each time, so the feeding operation is a labor-intensive job for mud workers. In order to r...
