Description

[0001] MUD DISTRIBUTION APPARATUS AND SYSTEM [0002]

The present invention relates to a mud dispensing device and system.

The drill ship is a vessel that drills oil and gas underground in the sea floor. To drill a hole in the seabed through a drill rig, you must first be able to destroy the rock and effectively remove the excavated rock debris. And the hole should not collapse, and the oil or gas should be blown away. For this purpose, the mud circulation method is used.

The mud circulation system feeds the mud at high pressure while bringing the drilling pipe down to the seabed. The mud arrives at the tip of the drill pipe is injected with a strong pressure from the nozzle and after the injection it is pushed up through the gap between the wall of the well and the drilling pipe. At this time, the soil and rock debris that have been pushed together with the mud that is pushed up together are transported together, and the flowability supplied by the mud and the drilling torque of the drill progress.

In such a mud circulation system, a plurality of mud pumps for supplying the mud are required. Each of the mud pumps is provided with a plurality of discharge pipes, a gate valve, a mud gutter, a shale shaker, and the like Respectively.

On the other hand, the mud put into the borehole for drilling operations in drilling or semi-submersible drilling rigs is returned to the drilling rig or semi-submersible drilling rig through the riser and then moved to the shale shaker through the mud return line for processing (eg re- do.

Open Patent Application No. 2012-0132595 discloses a drilling mud supply device.

In some embodiments of the present invention, inflow line 200 may be formed from a pipe. Some of the muds introduced into the mud dispense box 100 by the inflow line 200 are conveyed to the shale shaker 402 via the supply line 302 and are delivered by the inflow line 200 to the mud dispense box 100 may be transported to shale shaker 404, for example, via supply line 304. [

The mud dispensing box 100 may include openings 502, 504, 506, 508, 510, 512, 514 that are connected to the supply lines 302, 304, 306, 308, 310, The mud entering the inflow line 200 may enter the openings 502, 504, 506, 508, 510, 512, 514. For example, some of the muds entering the inflow line 200 may flow into the openings 502, while other portions of the muds that flow into the inflow line 200 may enter the openings 504. In some embodiments of the present invention, the spacing between openings 502, 504, 506, 508, 510, 512, 514 may be identical to each other, for example, between openings 502 and 504 May be the same as the distance between the opening 504 and the opening 506. [

Figures 4 to 6 are cross-sectional views of a supply line connecting the mud dispensing box and the shale shaker.

4, one end of the supply line 302 may be connected to the shale shaker 402 and the other end of the supply line 302 may be connected to one side of the mud dispense box 100. Referring to FIG. In FIG. 3, the cross section of the supply line 302 is formed in the shape of a letter 'A', but is not limited thereto. 4, the inflow line 200 is formed on a side wall opposite to one side of the mud distribution box 100 to which the supply line 302 is connected. However, the inflow line 200 is not limited to the inflow line 200, May be formed on the upper surface of the mud dispensing box 100.

5, one end of the supply line 302 'is connected to the shale shaker 402, the other end of the supply line 302' is connected to one side of the mud distribution box 100 at two points, Shaped pipe. As previously described, the supply line 302 'is again a dedicated path for moving the mud to the shale shaker 402, for example, by another shale shaker 404, 406, 408, 410, 412 It is an independent path that is not shared.

6, one end of the supply line 302 " is connected to the shale shaker 402 and the other end of the supply line 302 " is connected to the bottom of the mud distribution box 100, have. That is, the opening 502 '' to which the mud dispense box 100 and the supply line 302 '' are connected may be formed at a lower position than the inflow line 200. In addition, the inflow line 200 may be formed in a sidewall opposite the one side to which the supply line 302 of the mud dispense box 100 is connected.

FIG. 7 is a perspective view of a mud dispensing apparatus according to another embodiment of the present invention, and FIG. 8 is a top view of a mud dispensing box used in a mud dispensing apparatus according to another embodiment of the present invention.

7, a mud dispensing apparatus 1 according to another embodiment of the present invention may include a mud dispensing box 100 and one or more supply lines 302, 304, 306, 308. As shown in FIG. The mud dispensing box 100 may further include an inflow line 200 for allowing the mud to be introduced into the mud dispensing box 100 from the outside.

Referring to Figure 8, the mud dispensing box 100 may include openings 502, 504, 506, 508 that are connected to supply lines 302, 304, 306, 308. The mud entering the inflow line 200 may enter the openings 502, 504, 506, and 508. For example, some of the muds entering the inflow line 200 may flow into the openings 502, while other portions of the muds that flow into the inflow line 200 may enter the openings 504. In some embodiments of the invention, the spacing between openings 502, 504, 506, 508 may be equal to each other, e.g., the spacing between openings 502 and openings 504 is greater than the distance between openings 504 And the opening 506. In this case,

Meanwhile, a mud distribution system according to an embodiment of the present invention includes N shale shakers (where N is a natural number of 2 or more) shale shakers; A mud dispensing device located above the N shale shakers; An inflow pipe for introducing the mud into the mud dispensing device; And N supply pipes, one to one, corresponding to the N shale shakers and spaced apart from one another, each supply pipe may include N supply pipes directly connecting the corresponding shale shaker and mud dispensing device.

Conventionally, a plurality of shale shakers share a portion of a mud return line (i.e., a mud feed line that conveys a mud to a shale shaker), so that the mud is not evenly distributed to each shale shaker, There was a concentration problem. However, according to various embodiments of the present invention, it is possible to prevent overloading of specific shale shakers by evenly distributing the muds to a plurality of shale shakers, further improving the efficiency of operation of the mud dispensing device and shale shaker have.
