Description
Technical field
The present invention relates to a kind of deep drilling rig control pressurer system, specifically a kind of deep drilling rig monolithic drilling pressure control system.
Background technology
Deep drilling rig is the construction machinery of pore-forming operation in the engineering in the exploration of a kind of applicable hydrogeology, industrial or agricultural well, tunnel, gravity vent, shallow-layer coal bed gas and geothermal heating hole.It mainly utilizes hydraulic swivel head to drive rod boring, is threaded connection between each drilling rod; When drilling depth is more shallow, because drilling rod quantity is few, lightweight, therefore need to apply the requirement that extra plus-pressure makes it to meet drilling pressure, and this plus-pressure will reduce gradually with boring dark increase (i.e. the increase of drilling rod deadweight), therefore needs to regulate drilling pressure in real time.When boring is darker, drilling rod increasing number, weight becomes large, and the pressure therefore acted on drill bit becomes large, when drilling rod weight is greater than required drilling pressure, needs the extra lifting force (namely reduce pressure power) of applying to reduce the pressure acted on drill bit.
At present, domestic deep drilling rig R & D Enterprises all adopts pressurization, the mode that decompression separately controls.Pressurization operating mode generally adopts mechanical gravity formula drill collar to pressurize, and namely relies on the weight of drilling rod upper end metal drill collar to realize pressurization and creeps into, and this form is not only heavy to fall behind, and plus-pressure is unadjustable.External deep drilling rig R & D Enterprises generally adopts the form of hydraulic control to carry out pressurizeing and decompression is crept into, but is split type, but split-type design makes the volume of control panel increase, and brings certain difficulty to the arrangement of panel design.
Summary of the invention
The object of the present invention is to provide a kind of deep drilling rig monolithic drilling pressure control system, integrate pressurization and decompression is crept into, can weigh to drilling tool, realize the real-time adjustment of pressurization to drilling rod and decompression simultaneously.
To achieve these goals, the technical solution used in the present invention is: a kind of deep drilling rig monolithic drilling pressure control system, comprise pressurizing control system and decompression weighing control system, pressurizing control system comprises moulding pressure table, pressurization control valve, and decompression weighing control system comprises lifting control valve, one way valve and table of weighing;
All hydraulic element in pressurizing control system and decompression weighing control system is integrated on valve body, A1, B1 hydraulic fluid port of valve body connects hydraulic system main control valve, A mouth, B mouth connect promote mainly oil cylinder, T1 mouth connects hydraulic oil container; Valve body is also provided with function reversal valve, and moulding pressure table is connected with pressurization control valve oil-in by the M1 mouth of valve body, and the B mouth of pressurization control valve drain tap, function reversal valve is communicated with the B1 mouth of valve body; The A mouth of function reversal valve is communicated with the A1 mouth of valve body, T mouth be communicated with promote control valve spring chamber drain tap and valve body T1 mouth, P mouth with promote control valve draining chamber and be communicated with; Promote control valve oil-in by the M2 mouth of valve body and list catenation of weighing, be connected with the B mouth of valve body simultaneously; One way valve is arranged between the B mouth of valve body and B1 mouth.
Also choke valve is provided with between the P mouth and lifting control valve of function reversal valve.
Function reversal valve is 3-position 4-way hand-operated direction valve.
With prior art control system, the present invention integrates pressurizing control system and decompression weighing control system: the while that in pressurizing control system, pressurization control valve carrying out pressurization to drill bit, moulding pressure table shows moulding pressure in real time; Decompression weighing system realizes weighing to drilling tool, reading of weighing directly reads on table, determine to pressurize to drill bit or reduce pressure according to drilling tool weight, changed by function reversal valve function between two systems, achieve concentrated, real-time control, easy to operate, simple and fast, enormously simplify hydraulic circuit; And be provided with choke valve, the safety of protection drilling pressure control system.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1: deep drilling rig monolithic drilling pressure control system of the present invention, comprise pressurizing control system and decompression weighing control system, pressurizing control system is made up of moulding pressure table 1, pressurization control valve 2, and decompression weighing control system is formed by promoting control valve 5, one way valve 6 and table 7 of weighing; A1, B1 hydraulic fluid port of valve body 8 connects hydraulic system main control valve, A mouth, B mouth connect promote mainly oil cylinder, T1 mouth connects hydraulic oil container.
Pressurizing control system and all hydraulic element reduced pressure in weighing control system are integrated on valve body 8; Valve body 8 is also provided with function reversal valve 3, moulding pressure table 1 is connected with pressurization control valve 2 oil-in by the M1 mouth of valve body 8, the B mouth of pressurization control valve 2 drain tap, function reversal valve 3 is communicated with the B1 mouth of valve body 8, the A mouth of function reversal valve 3 is communicated with the A1 mouth of valve body 8, T mouth be communicated with promote control valve 5 spring cavity drain tap and valve body 8 T1 mouth, P mouth with promote control valve 5 draining chamber and be communicated with; Promote control valve 5 oil-in to be connected with table 7 of weighing by the M2 mouth of valve body 8, be connected with the B mouth of valve body 8 simultaneously; One way valve 6 is arranged between the B mouth of valve body 8 and B1 mouth.
Native system is also provided with choke valve 4 between the P mouth and lifting control valve 5 of function reversal valve 3, when drilling rod is when transferring or in weighing process, stall is fallen, closes the safety that choke valve 4 protects equipment and system.
Function reversal valve 3 is electric change valve also can be 3-position 4-way hand-operated direction valve, and preferred 3-position 4-way hand-operated direction valve, staff can switch according to the pressure size of field condition and drilling tool in real time in real time, simply effectively.
As shown in Figures 2 and 3: rotate to regulate and promote control valve 5 pairs of drilling tools and weigh, reading of weighing directly reads weighing on table 7, determines to pressurize to drill bit or reduce pressure according to drilling tool weight.Rotate the drilling pressure regulating pressurization control valve 2 can control deep drilling rig, and drilling pressure can show on moulding pressure table 1 in real time, turn clockwise increase drilling pressure, is rotated counterclockwise reduction drilling pressure.Function reversal valve 3 is switched by operating grip, after switching to left position, promote the size that control valve 5 can control decompression power, turn clockwise increase decompressed pressure, be rotated counterclockwise reduction decompressed pressure, drilling tool creeps into according to required drilling pressure, and decompressed pressure is directly read by table 7 of weighing.When deep drilling rig is by the oil-feed of B1 mouth, when carrying out the operation of lifting drilling tool, regulate and promote the size that control valve 5 can control adherence pressure; adherence pressure directly shows weighing on table 7; when promoting control valve 5 and losing efficacy, directly oil circuit can be closed by choke valve 4, the safety of proterctive equipment.
In sum, the present invention is by pressurized control, Decompression Controlling, and the function i ntegration such as adherence pressure control are in a hydraulic control module valve body 8; achieve centralized Control, easy to operate, simple and fast; enormously simplify hydraulic circuit, and be provided with safety guard, the safety of protection system.
