Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cementing grouting, in particular to a casing rotary table surface grouting tool. Background Art
[0002] In cementing grouting operations, the traditional casing grouting tool is a homemade "F" tube. The high-pressure hose of cementing is transferred to a low-pressure hose at the union, and the low-pressure hose is connected to the "F" tube. The "F" tube is then hung on the female buckle end of the casing. After opening the ball valve on the "F" tube, the operator holds the "F" tube by hand for grouting operations.
[0003] In order to prevent the "F" pipe from bouncing off and injuring people due to the reaction force of the mud, the operator needs to hold the "F" pipe with his hands continuously during the entire grouting process. This makes the depth of the casing directly affect the labor intensity and work safety of the operators. After a long time of operation, the workload of the operators is very heavy and the work safety cannot be guaranteed. In addition, when using traditional "F" pipe grouting tools, each time a casing is grouted, the "F" pipe grouting tool must be reloaded and unloaded, which is time-consuming and labor-intensive.

[0028] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.
[0029] See also Figure 1 The present embodiment provides a casing turntable surface grouting tool, comprising a slurry delivery pipeline 1 and a height adjustment seat 2. The slurry delivery pipeline 1 extends in a straight line, and a ball valve 3 is installed in the middle position of the slurry delivery pipeline 1, and elbows are sleeved at the feed port and the discharge port. The feed port of the slurry delivery pipeline 1 can be rotatably arranged on the height adjustment seat 2 and can be lifted and lowered in the vertical direction with the height adjustment seat 2. The slurry delivery pipeline 1 is perpendicular to the height adjustment seat 2, and the elbow opening of the discharge port of the slurry delivery pipeline 1 is arranged to face downward.
[0030] Before using the casing turntable surface grouting tool of this embodiment, it is necessary to first connect the high-pressure hose of cementing to a low-pressure hose at the union, and then connect the low-pressure hose to the feed port of the slurry delivery pipeline 1. Then, the position of the slurry delivery pipeline 1 is adjusted so that the elbow of the discharge port is facing the grouting port at the top of the casing. After that, by opening the ball valve 3 on the slurry delivery pipeline 1, grouting can be done into the casing.
[0031] The casing lowering turntable surface grouting tool of the present embodiment can not only fix the slurry delivery pipeline 1 by means of the height adjustment seat 2, without the need for the operator to continuously hold it by hand, so that the wellhead operators can pay more attention to other aspects of safety on site, greatly improving the safety factor of the entire casing lowering operation; and the height of the slurry delivery pipeline 1 can be adjusted by means of the height adjustment seat 2, and the position of the feed port of the slurry delivery pipeline 1 can be adjusted by rotation, so that the feed port of the slurry delivery pipeline 1 can be turned to the wellhead or moved away and retracted, without the need for frequent loading and unloading of the grouting tool, thereby greatly reducing the physical loss of the operators and improving the working efficiency.
[0032] Preferably, see Figure 1 and Figure 2 The elbow sleeved at the feed inlet of the slurry delivery pipeline 1 is a flexible elbow 4, and the elbow sleeved at the discharge outlet is a right-angle elbow 5. The lower 360° rotatable end of the flexible elbow 4 is arranged on the height adjustment seat 2 and can be lifted and lowered along the vertical direction with the height adjustment seat 2, and the upper 360° rotatable end is sleeved at the feed inlet of the slurry delivery pipeline 1. The slurry delivery pipeline 1 can freely rotate 360° in the circumference relative to the height adjustment seat 2 through the flexible elbow 4, so that the feed inlet can be turned to the wellhead or moved away and retracted; at the same time, the circumferential rotation between the slurry delivery pipeline 1 and the height adjustment seat 2 is realized through the flexible elbow 4, which can facilitate the operator to adjust the circumferential position of the feed inlet relative to the height adjustment seat 2 by a single operation.
[0033] Preferably, see Figure 1 and Figure 2 The slurry delivery pipeline 1 includes a delivery pipe 101, an NPT short joint 102 and a union 103. The ball valve 3 is installed on the delivery pipe 101. One end of the delivery pipe 101 is connected to the right-angle elbow 5, and the other end of the delivery pipe 101 is connected to the NPT short joint 102, the union 103 and the flexible elbow 4 in sequence.
[0034] Specifically, in this embodiment, the height adjustment range of the height adjustment seat 2 is 0.8-1.3m; the nominal pressure of the ball valve 3 is 1.6MPa; the model of the right-angle elbow 5, the delivery pipe 101, the NPT nipple 102, the union 103 and the flexible elbow 4 are all 1502, and the size is 2".
[0035] Preferably, see Figures 1 to 3The height adjustment seat 2 includes a bottom plate 201, a protective tube 202 and an inner tube 203. The protective tube 202 is vertically fixed on the bottom plate 201. The inner tube 203 is coaxially arranged in the protective tube 202 so as to be axially movable, and the top of the inner tube 203 is connected to the feed port of the slurry delivery pipeline 1. Thus, the bottom plate 201 and the protective tube 202 provide fixation for the slurry delivery pipeline 1. When the weight of the bottom plate 201 and the protective tube 202 is not enough to ensure the stability of the slurry delivery pipeline 1, additional weights can be pressed on the bottom plate 201 to ensure the fixation effect of the slurry delivery pipeline 1. At the same time, the setting of the inner tube 203 allows the operator to adjust the height of the slurry delivery pipeline 1 by adjusting the axial position of the inner tube 203 in the protective tube 202.
[0036] Preferably, in this embodiment, the bottom plate 201, the protective tube 202 and the inner tube 203 are all made of metal, the bottom plate 201 and the protective tube 202 are fixed by electric welding, and the inner tube 203 and the slurry conveying pipeline 1 are also fixed by electric welding.
[0037] Preferably, see Figure 3 The height adjustment seat 2 also includes a limit pin 204. The bottom of the protective tube 202 is provided with a plurality of limit holes at equal intervals along the axial direction. The bottom of the inner tube 203 is provided with a pair of through holes. The limit pin 204 passes through the pair of limit holes and the pair of through holes at the same time and limits the inner tube 203 axially in the protective tube 202. The circumferential limit between the protective tube 202 and the inner tube 203 is achieved by the matching of the pin hole. Not only can the height of the slurry delivery pipeline 1 be adjusted at any time by adjusting the through position of the limit pin 204, but it is also easy to operate.
[0038] Preferably, four pairs of limiting holes are evenly spaced along the axial direction at the bottom of the protection tube 202, and the distance between the lowest pair of limiting holes and the bottom plate 201 is 10-60 cm.
[0039] After the design of the casing turntable surface grouting tool of this embodiment was completed, it was tested in several wells on site and the effect was very good, labor-saving and safe, especially in the casing operation of the production well group, the advantages were more obvious and the expected effect was achieved. The casing turntable surface grouting tool of this embodiment has a simple structure and is easy to promote, and can be promoted to all drilling and completion casing grouting operations.
[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
