Abstract
The utility model discloses a multi-configuration instruction down-transmission device which comprises a receiving stand pipe, a receiving mud pit and high-pressure pipes which are connected with the receiving stand pipe and are used for injecting mud into the receiving mud pit. The multi-configuration instruction down-transmission device is characterized in that at least two high-pressure pipes are arranged between the receiving stand pipe and the receiving mud pit, and the high-pressure pipes are provided with mud flow control valves which are used for controlling mud flow. According to the multi-configuration instruction down-transmission device, damage of one mud flow control valve does not affect normal working of other mud flow control valves, and the reliability and the production efficiency of equipment are improved.
Description
Technical field
The utility model relates under a kind of mud and passes device, particularly, relates to a kind of polygamy and puts under the instruction and pass device.
Background technology
As shown in Figure 1, pass device under existing single configuration-direct and only have a mud flow rate control valve, mud is by connecing standpipe 1 and be injected in the stock tank 4 that grafts clay with connecing the high-voltage tube 2 that standpipe links to each other, and carries out the mud shunting and finishes under the instruction and pass thereby mud flow rate control valve 3 is used for controlling the unlatching of the inside valve block.Because valve block under high-pressure slurry washes away, will be washed out within a certain period of time and be lost efficacy, and must change valve block and could carry out passing under the instruction again.Because mud pressure is higher, flow is larger, the effective time of valve block is just shorter, if run into heavy duty service, the working time that instruction passes down device just can not guarantee the single port well operations, and it is high owing to day hire charge on marine drilling platform, do not change so can not carry out if having time valve block, therefore will affect operation, cause operating efficiency low, operating cost raises.And pass device if there is fault under single configuration-direct, backup can only not quit work, and causes operating efficiency low.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model discloses a kind of polygamy and put under the instruction and pass device, the mud flow rate control valve of having avoided single configuration-direct to pass down device damages and the problem that causes equipment to work.
Polygamy provided by the utility model is put under the instruction and is passed device, comprise connect standpipe, stock tank and connect the high-voltage tube that standpipe is connected, is used for mud is injected into the described stock tank that grafts clay with described grafts clay, wherein said connect standpipe and graft clay between the stock tank at least two high-voltage tubes are set, a mud flow rate control valve that is used for the control mud flow rate all is set on the described high-voltage tube
Preferably, the described mud flow rate control valve on each high-voltage tube and described connecing all arrange a plug valve between the standpipe.
Preferably, described mud flow rate control valve is connected with dynamical system, and described dynamical system is connected with described control system, and described control system is controlled described mud flow rate control valve by described dynamical system.
The utility model adopts polygamy to put under the instruction and passes device, does not affect the normal operation of other mud flow rate control valve in the situation that single mud flow rate control valve damages, and has improved reliability and the production efficiency of equipment.
Description of drawings
Fig. 1 passes the apparatus structure schematic diagram under single configuration-direct of the prior art;
Fig. 2 is that polygamy is put the structural representation that instruction passes down device among the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing embodiment of the present utility model is elaborated.Need to prove that in the situation of not conflicting, the feature among present embodiment and the embodiment is any combination mutually.
Core concept of the present utility model is: only have a mud flow rate control valve for passing device under single configuration-direct of the prior art; if the mud flow rate control valve causes the problem of damaging and equipment can't being worked; design one cover polygamy is put under the instruction and is passed device; plural high-voltage tube is set connecing standpipe and graft clay between the stock tank; one mud flow rate control valve is set on each high-voltage tube; therein in the situation of a mud flow rate control valve damage; other mud flow rate control valve can be worked as usual; need not shut down the mud flow rate control valve that more renews, the safety that has improved operating efficiency and equipment.
In an embodiment provided by the utility model, provide under a kind of pair of configuration-direct and passed device, for example shown in Figure 2, comprise connect standpipe 1, graft clay stock tank 4 and with the high-voltage tube 2 that connects standpipe 1 and be connected, be used for mud is injected into the stock tank 4 that grafts clay, connect standpipe 1 and graft clay two high-voltage tubes 2 are set between the stock tank 4, a mud flow rate control valve 3 that is used for the control mud flow rate all is set on each high-voltage tube 2.When under carrying out instruction, passing operation, open first the front plug valve of one of them mud flow rate control valve, mud is flow through in the mud flow rate control valve of opening, and the plug valve before another mud flow rate control valve cuts out, make its mud flow rate control valve not have the slurry flows mistake, thereby realize passing under mud shunting and the instruction.For example among Fig. 2, the plug valve before the mud flow rate control valve of left-hand side is opened, and the plug valve before the mud flow rate control valve of right-hand side cuts out.
After the interior valve block of mud flow rate control valve (for example, the mud flow rate control valve of left-hand side among Fig. 2) of opening is washed away badly, close the front plug valve of mud flow rate control valve of opening, mud is not flow through in corresponding mud flow rate control valve; Open again the front plug valve (for example, the mud flow rate control valve of right-hand side among Fig. 2) of another mud flow rate control valve, mud is flow through in corresponding mud flow rate control valve, thereby again realize passing under mud shunting and the instruction.
In order to reach the automatically accurately control to the mud flow rate control valve, can be by control system by dynamical system control mud flow rate control valve.Certainly, also can connect standpipe 1 and graft clay between the stock tank 4 as required, more high-voltage tubes 2 are set, the one mud flow rate control valve 3 for the control mud flow rate all is set on each high-voltage tube 2, need to use a certain mud flow rate control valve and divide when flowing down teletype command, only need open connected plug valve and get final product; And other plug valve cuts out, and avoids other mud flow rate control valve to contact with high-pressure slurry, improves reliability and safety.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model is not to limit the utility model.Technician under any the utility model in the technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation in the details that reaches of implementing in form; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
