Abstract
The utility model provides a solid control system for petroleum drilling. The solid control system for the petroleum drilling comprises cylindrical subsidiary tanks, an upper frame, stand columns, stirrers, subsidiary tank ladders and a base; the stand columns are welded around the cylindrical subsidiary tanks, the upper portions of the cylindrical subsidiary tanks are provided with inlet holes, the cylindrical subsidiary tanks are opened, and the tank opening of each cylindrical subsidiary tank is provided with a sand blocking plate; the cylindrical subsidiary tanks are a plurality in number; the bottom ends of the stand columns are assembled on the skid-mounted type base in a welded mode, and the top portions of the stand columns are welded with the upper frame; each subsidiary tank ladder is installed inside each cylindrical subsidiary tank, and communication pipes are installed among the subsidiary tanks; and each stirrer is installed on each cylindrical subsidiary tank. The solid control system for the petroleum drilling has the advantages that by means of the technical scheme of the solid control system for the petroleum drilling, full and even blunging can be achieved; all pipelines are placed outside, and the effective volume is equal to the total volume; bottom sand removal is adopted, and sand removal effects are good; and bottom suction is achieved for all pumps, and zero suction of the pumps is achieved. The solid control system for the petroleum drilling is convenient to operate and has the advantages of being simple in structure, convenient to maintain, low in manufacturing cost, high in production efficiency and the like.
Description
Technical field
The utility model belongs to the petroleum drilling and mining technical field, especially relates to the solid controlling system that a kind of oil drilling is used.
Background technology
At present, domestic petroleum drilling well industry solidification control system for well drilling liguid is comprised of some rectangular tanks.There is following shortcoming in it.
1. because tank body is rectangular configuration, mud stirring is inhomogeneous, has the dead angle; Side plate is corrugated sheet simultaneously, and sand cleaning gate is offered in the side, causes sand removal inconvenience.
2. tank gut line complicated layout takies the jar space, greatly dwindles dischargeable capacity, not easy-maintaining.
3. the Pump Suction Nozzle center of rectangle tank body is higher, and pump can not realize that zero sucks.
It is the solid controlling system of the rectangular tank composition at the end that there are some half elliptics in the overseas market, and the part pipeline is built-in, and part has been avoided the problems referred to above, stirs the dead angle but also exist.
Summary of the invention
Problem to be solved in the utility model provides a kind ofly can make that drilling fluid stirs, sand removal is convenient, effectively utilize the liquid-solid control of the circular drilling system of tank internal volume.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of oil drilling solid controlling system is characterized in that: described oil drilling comprises cylindrical sub-tank, upper ledge, column, agitator, sub-tank ladder, base with solid controlling system; Be welded with column around the described cylindrical sub-tank, top is provided with hand-hole, and described cylindrical sub-tank is uncovered, and the tank mouth is provided with the sand block plate; Described cylindrical sub-tank is some; Described column bottom assembly welding on a skid-mounted base, described column top and tank upper ledge assembly welding; Be provided with sub-tank ladder in the described cylindrical sub-tank, be provided with communicating pipe between the sub-tank; An agitator is installed on the described cylindrical sub-tank.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, can realize that mud stirring is full and uniform; All pipelines are external, and dischargeable capacity equals total measurement (volume); Adopt the bottom sand removal, sand removal is effective; All pump bottoms suck, and realize that pump zero sucks.More convenient to operate, have simple in structurely, easy to maintenance, processing cost is low, the production efficiency advantages of higher.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure:
1. cylindrical sub-tank; 2. upper ledge; 3. column; 4. agitator; 5. sub-tank ladder; 6. base
The specific embodiment
As shown in Figure 1, a kind of oil drilling solid controlling system of the utility model comprises cylindrical sub-tank 1, upper ledge 2, column 3, agitator 4, sub-tank ladder 5, base 6; Be welded with column 3 around the cylindrical sub-tank 1, top is provided with hand-hole, and cylindrical sub-tank 1 is uncovered, and the tank mouth is provided with the sand block plate; Cylindrical sub-tank 1 is some; Column 3 bottom assembly weldings on a skid-mounted base 6, column 3 tops and tank upper ledge 2 assembly weldings; Be provided with sub-tank ladder 5 in the cylindrical sub-tank 1, be provided with communicating pipe between the sub-tank; An agitator 4 is installed on the cylindrical sub-tank 1.
The course of work of this example: have the problems such as religion version poor performance, sand removal and fitting operation difficulty for rectangular tank, this project has been developed cylindrical can.The cylindrical can dischargeable capacity of this system is about 100%, and drilling fluid is stirred; The Pump Suction Nozzle of cylindrical can is positioned at pot bottom, and fully drilling fluid in the suction tank is to receive drilling fluid 100% to suck and waste liquid 100% discharging.
Each well-drilling liquid circulation pot forms by several cylindrical sub-tanks, is welded with column around each cylindrical sub-tank, leans on 4 root post bottom assembly weldings on a skid-mounted base, top and tank upper ledge assembly welding.The tank deck face is checkered steel plate, each is cylindrical tank top is provided with 700mm*700 ~ hand-hole.Single cylindrical tank is uncovered, and the tank mouth is provided with the sand block plate.Sand cleaning gate is opened in the tank bottommost, with the jet wash pipeline.
Drilling fluid tank forms by base, upper ledge, column, some cylindrical sub-tanks, sub-tank ladder 5 parts.Every sub-tank respectively with the welding of 4 root posts, every root post up and down two ends respectively with base and upper ledge assembly welding.Be provided with in each sub-tank and foretell the tank ladder, be provided with communicating pipe between the sub-tank.On each cylindrical sub-tank and an agitator is installed.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
