Description
Technical field:
The utility model belongs to the oil field equipment field, relates to a kind of automatic control medicine system, especially a kind of long-range well head automatic control medicine system.
Background technology:
Crude oil in China is rich in wax; according to statistics; the content of wax almost accounts for 90% of whole output crude oil over 10% crude oil; and the content of wax of most of crude oil extraction is all more than 20%; have even up to 40%-50%; thereby in the oil recovery manufacturing process in oil field, the down-hole string of oil well and gathering line just might be because the impacts of wax deposition, cause the problems such as the undesired or wellhead back pressure of oil well production is high.Address these problems, need to carry out the clear wax control of tubing string, the existing wax removal technology of China has mechanical paraffin removal, heat to wash down the technology such as wax control, paraffin control with inhibitor, magnetic paraffin control, undercoating, but use at present maximum dewaxing methods or paraffin control with inhibitor, namely adopt from well head and add the paraffin remover medicament, stop the formation of pit shaft wax dirt, thereby reduce wellhead back pressure, safeguard the normal production of oil well.
Some oil fields, carry out to the oil well inner oil tube ring that chemical dosing wax removal is necessity in oil producing operation at home.at present, the mode of traditional artificial regularly upper well dosing is still adopted in the well mouth of oil well dosing, there is complicated operation, labour intensity is large, inefficiency, the personnel vehicle of employing waits problem often, along with the digitized development in oil field, be badly in need of a kind of low permeability oil field that is suitable for from the new equipment of formula well group well head remote automatic control dosing, make the well mouth of oil well dosing can realize automation remote control, the one many wells of machine, data acquisition, teletransmission, minimizing personnel and vehicle employ number of times, significantly reduce the labour intensity of workman's dosing, dosing frequency and dose are accomplished meticulous controlled, reduce the well head medicine-adding cost, really realize " the quantification of well head medicine-adding, ensured sustained development, controlledization, unmanned ", strided forward major step to the intelligentized direction of well mouth of oil well.
The utility model content:
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of long-range well head automatic control medicine system is provided, and has solved the technical problem of " quantification, ensured sustained development, controlledization, unmanned " of well head medicine-adding.
The purpose of this utility model solves by the following technical programs: long-range well head automatic control medicine system comprises remote control terminal, the switch board that is connected with remote control terminal, medicine-chest, high-pressure metering pump and electromagnetism valve island; Described medicine-chest is connected with high-pressure metering pump by ball valve, and high-pressure metering pump is connected with electromagnetism valve island; Described switch board is connected with electromagnetism valve island with high-pressure metering pump by circuit simultaneously.
Described medicine-chest top is provided with inlet filtering apparatus, and medicine-chest and ball valve junction are provided with the egress filtering device.
Be provided with pressure meter between described high-pressure metering pump and electromagnetism valve island.Described electromagnetism valve island is made of a return valve and 8 electromagnetic valves, and return valve is connected with the high pressure measurement pump intake, and electromagnetic valve is connected with the individual well well head, is provided with flap valve between electromagnetic valve and individual well well head.Described remote control terminal and switch board are wireless connections.
Long-range well head automatic control medicine system of the present utility model, be suitable for low permeability oil field from the dosing of formula well group well head remote automatic control, make the well mouth of oil well dosing can realize automation remote control, the many wells of machine, data acquisition, teletransmission, minimizing personnel and vehicle employ number of times, significantly reduce the labour intensity of workman's dosing, dosing frequency and dose are accomplished meticulous controlled, reduce the well head medicine-adding cost, really realize " quantification, ensured sustained development, controlledization, unmanned " of well head medicine-adding, strided forward major step to the intelligentized direction of well mouth of oil well.
