Abstract
The utility model relates to a ground automatic high pressure regulation relief valve device for high-pressure waterjet perforation in petroleum exploitation, which consists of a tubing tee, a filter, a valve body, a pressure sensor, a proportional pressure valve, a control circuit, an enlarging valve, a low-pressure return tube, a power supply, a power switch, a pressure display screen, a pressure regulation knob and a control box, the tubing tee is connected with a downhole tubing through screw threads, the filter is connected with the tubing tee and the valve body through screw threads, the upper part of the pressure sensor is connected with the pressure display screen through a circuit, the proportional pressure valve and the control valve are connected with the pressure regulation knob through a circuit, the enlarging valve is connected with the valve body through screw threads, the low-pressure return tube is connected with the enlarging valve through screw threads, the power supply and the power switch are connected with the control box through a circuit, and the pressure display screen, the power switch and the pressure regulation knob are mounted in the control box and connected through a circuit. The device solves the problem that since the flow of the relief valve is manually regulated on the ground in the prior art, the regulation valve body part can be easily burst to hurt people within the range of high pressure.
Description
Technical field:
A kind of ground high pressure that the utility model relates in the construction of oil exploitation mesohigh water jet perforation is regulated the overflow valve device automatically.
Background technology:
At present, adopt the combination of high-pressure water jet perforation tool in the oil extraction process, above ground portion manual adjustment overflow valve flow, guarantee the smooth perforation of down-hole waterpower perforation tool, since ground under the 40-50Mpa state people for carrying out continual adjusting, be easy to occur in high pressure range the regulation valve body parts existing injury personnel accident that flies out that jumps, this operation does not simultaneously meet present HSE constructing operation standard.
The utility model content:
The purpose of this utility model provides a kind of ground high pressure and regulates the overflow valve device automatically, this device solves in the oil exploitation mesohigh jet perforation tool combination that exists in the prior art, above ground portion is with manual adjustment overflow valve flow, and the regulation valve body parts unsafe problem of hurting sb.'s feelings that jumps appears in manual adjustment easily in high pressure range.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ground high pressure is regulated the overflow valve device automatically by the oil pipe threeway, strainer, valve body, pressure sensor, proportional pressure valve and control circuit, amplifying valve, the low pressure return pipe, power supply, power switch, the pressure display screen, the pressure adjusting knob, control box is formed: oil pipe threeway and down-hole oil tube screwed connection, strainer and oil pipe threeway, the valve body screwed connection, pressure sensor top is connected with pressure display screen circuit, proportional pressure valve and control circuit are connected with pressure adjusting knob circuit, amplifying valve and valve body screwed connection, low pressure return pipe and amplifying valve screwed connection, power supply, power switch is connected the pressure display screen with circuit with control box, power switch, the pressure adjusting knob is installed in circuit connection in the control box.During work, at first the ground high pressure is regulated the overflow valve device automatically and be installed on well head, wherein oil pipe threeway connection reaches with the cementing truck pipeline and is connected with this device, carry out in the waterpower deep penetration work progress, the pressure source part that cementing truck provides enters the down-hole, another part is shunted by control device, reaching under the situation of pressure, the excess liquid shunting is discharged, by pressure sensor inlet fluid pressure is passed in the pressure display screen, the voltage swing of adjusting 0-24V is transferred to the proportional pressure valve instruction through control circuit, thereby the pressure size that the resize ratio pressure valve is controlled, again through the amplification of amplifying valve and proportional pressure valve and the part water yield of shunting function shunting press device, obtain the controlled pressure of needs, control the inflow of perforation tool, can control the pressure of inlet, shunt the unnecessary water yield and return in the water pot recycling by the low pressure return pipe.
The beneficial effects of the utility model are owing to realized ground remote pressure control, to have avoided the moving potential safety hazard of regulating overflow valve of well head armrest in the past, thereby saved the great amount of cost expense, guaranteed that the job site do not pollute, the hydraulic perforating operation procedure is simplified, and has improved construction and operating efficiency.
