The investment of water injection for a long-distance high-pressure pipeline can be saved, the injection pressure can be guaranteed, the whole water injection process can be succinctly and effectively completed, and the energy-saving and consumption-reducing effect can be obvious, so that a prominent economic benefit is brought to a whole oil extraction industry.
Description
One. technical field: the utility model relates to a kind of oil field flood pattern, particularly relates to a kind of screw pump pressurized water injection system.
Two. background technique: the exploitation of domestic each elephant at present all gets into the middle and later periods, and in order to improve crude output, the most of oil-bearing stratum flooding that adopts in oil field promptly adopts boosting water injection pump to improve water injection pressure to keep formation pressure, reaches the raising oil displacement efficiency.But it is outstanding day by day that the fractional water flooding individual well of each elephant or block high pressure are shorted problem, impels people to recognize the necessity of development pressurized water injection technology gradually.Up to now, boosting water injection pump has begun to take shape centrifugal, reciprocating type two big types, dozens of kind.The oil field has also formed high pressure water injection network in large scale, but the high pressure water injection system is big owing to the teletransmission energy consumption, and cost is high, and shortcomings such as track laying and control flow complicacy make present cost for oil production high.
Three. the model utility content:
The utility model technical problem to be solved is: overcome the deficiency of existing technology, provide a kind of sealing load high, low in energy consumption, operate steadily and screw pump pressurized water injection system that the phase of being excused from a college course is long.
The technological scheme of the utility model is: a kind of screw pump pressurized water injection system; Contain permagnetic synchronous motor and screw pump; The output shaft of said permagnetic synchronous motor is connected with protector; Said protector is connected with said screw pump through connector, and said permagnetic synchronous motor is connected with the interior controller of control cabinet through connecting line.
Be full of dynamo oil in the said protector chamber and be provided with a thrust bearing, said thrust bearing is born the axial force that said output shaft transmission is got off.Said controller is provided with the wireless remote control module, realizes telecontrol.
The beneficial effect of the utility model is:
1, the utility model is based on the single well pressure boost waterflood project of screw pump; Have the sealing load height, low in energy consumption, working medium does not have leakage, vibration is little, noise is low, operate steadily, be excused from a college course characteristics such as the phase is long; Popularizing application prospect is wide in the oil field, has good economic benefit.
2, the installation and maintenance of the utility model whole system are simple and reliable, and the discharge capacity scope is wide, and is easy to adjust.It saves the bulky equipment such as high pressure pump of the long-range conveying process of high pressure, and being supplied water naturally by low pressure to the conveying of well head gets final product, and reduces cost of equipment greatly.Because ground does not have the high pressure link, saves a series of high tension instrument equipment that involve great expense, avoided high pressure to transmit the potential safety hazard that causes simultaneously.Its pressure maximum reaches 30MPa, can regulate power automatically according to pressure, and energy-saving effect is quite obvious.
3, the utility model whole system realizes total digitalization operation and GPRS remote real-time monitoring, and is easy to operate, safe and reliable, is convenient to centralized management, reduces cost of labor greatly.In addition, protective function such as controller possesses to transfinite, overload and inlet and outlet pressure are unusual can be worked under 24 hours unmanneds' situation automatically.
4, that dislocation is installed is convenient for the utility model whole system, receives such environmental effects such as extraneous weather little, safe and reliable.In addition, its floor space is little, and maintenance is little at ordinary times, and mean lifetime is long, has reduced user cost.
5, the utility model adopts permagnetic synchronous motor to drive, and has realized low rotation speed large torque output, the non-inductive electric current excitation of rotor; Its power factor reaches more than 0.9; Thereby improved the quality factor of electrical network, reduced or cancelled the canceller in the corresponding electrical network, reduced cost of investment; Simplified electric network composition, be convenient to administer and maintain.Simultaneously, the efficient of permagnetic synchronous motor is high, and saving power is received remarkable economic efficiency and social benefit in apply in the oil field.
6, the protector structure simple and durable of the utility model employing; Protector is full of dynamo oil in the chamber, in establish a thrust bearing, the axial force of role-taking under pump shaft, connector, the transmission of protector axle; To thrust bearing the lubrication protection effect is provided simultaneously, increases the service life.
Four. description of drawings:
Fig. 1 is the structural representation of screw pump pressurized water injection system.
Five. embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-control cabinet, 2-terminal box, 3-protector, 4-permagnetic synchronous motor, 5-connector, 6-screw pump.
Screw pump pressurized water injection system contains permagnetic synchronous motor 4 and screw pump 6; Wherein, The output shaft of permagnetic synchronous motor 4 is connected with protector 3, and protector 3 is connected with screw pump 6 through connector 5, and permagnetic synchronous motor 4 is connected with control cabinet 1 interior controller through connecting line.
The utility model adopts permagnetic synchronous motor 4 to drive, and has realized low rotation speed large torque output, the non-inductive electric current excitation of rotor; Its power factor reaches more than 0.9; Thereby improved the quality factor of electrical network, reduced or cancelled the canceller in the corresponding electrical network, reduced cost of investment; Simplified electric network composition, be convenient to administer and maintain.
Screw pump 6 motion speed can height can be low, its outlet amount level pressure power can increase with the progression of pump, transports the kind and the range of viscosities broadness of liquid; Because the revolution part inertial force in the pump is lower, so can use very high rotating speed; Suction performance is good, has suction capacity; Flow is evenly continuous, vibrates for a short time, and noise is low; Compare with other rotary pump, not too responsive to the gas and the dirt that get into; Sturdy construction is installed maintenance easily.
Controller in the control cabinet 1 is to three closed loop controls of spinner velocity, position and the stator current of permagnetic synchronous motor 4; The accurately speed and the torque of control motor; Flexible level and smooth drive motor reduces system loss greatly, realizes whole system overall efficiency maximization operation.
As required, can on the controller of control cabinet 1, be equipped with the GPRS remote control module, can down-hole pressure and motor service data be passed to master control room, realize real time monitoring and control, need not execute-in-place and can realize that whole water filling link carries out in order.
