Abstract
The invention discloses a novel combined valve with functions of water mixing and thermal washing. The combined valve solves the problem that operation of water mixing regulation and inverse well washing needs to frequently go back and forth between a metering room and an oil well site. The combined valve comprises a straight-through stop valve body, an overflowing sleeve, a valve cover, a well washing valve rod, a water mixing valve rod and a pressure measuring mechanism, wherein the well washing valve rod is coaxially and concentrically connected with the valve cover in a sealing thread manner, and a sealing pair is constituted by a valve clack under the well washing valve rod and a valve seat in the valve body; the water mixing valve rod is coaxially and concentrically connected with the well washing valve rod in the sealing thread manner, and the sealing pair is constituted by a needle-shaped valve plug under the well washing valve rod and a valve plug seat arranged on the valve clack. According to the combined valve disclosed by the invention, the well washing valve rod is used for opening and closing a valve flow channel and realizing the well washing operation, the water mixing valve rod is used for timely regulating the water mixing flow and momentarily monitoring the back pressure of a single well, so that under control the water mixing operation does not need to go back and forth between a well opening and the metering room, operation is reduced, and labor intensity of a worker is lowered. The combined valve disclosed by the invention has the double functions of the water mixing and the thermal washing, so that a traditional assembled well opening device in the water mixing process on the ground of the site can be replaced.
Description
Technical field
What the oil well that the present invention relates to a kind of oil field used carries out the valve that water mixing and heat washes.
Background technique
Due to oilfield extraction crude oil winter because outdoor temperature is low, crude oil easily solidifies and poor fluidity, crude oil separates out paraffin easily at oil well casing, petroleum pipeline crystallization, blocking tubing and casing and petroleum pipeline, impact is produced and is caused line fracture security incident, in order to solve this problem, at present water-mixing flow assemblingization well head is mainly installed on production wellhead, in well head Field adjustment watering quantity and anti-flushing well operation, by giving petroleum pipeline mixed with hot water, diluent crude oil, promote temperature, reduce wax precipitation and crystallization, anti-flushing well operation is carried out from sleeve pipe hot-water flooding, remove tubing and casing wax deposition.Because prior art regulates water mixing and clean-out service on well head scene, well site affects large by outdoor temperature and well head is distant to metering room, watering quantity size can not be regulated in time, if watering quantity is excessive, cause waste resource, increase oil-water separation cost, watering quantity is little, water doping valve and the easy frozen block of pipeline or wax deposition, the serious petroleum pipeline that causes breaks, cause serious accident, light then impact is produced and is increased pumping unit lifting energy consumption, and workman needs according to outdoor temperature change and metering room returning-oil temperature and return pressure situation of change, frequently travel to and fro between metering room and oil wells in field, observation returning-oil temperature and pressure regulate watering quantity size, especially in the winter time under subzero more than the 30 extremely cold weather conditions spent, at well head work on the spot bad environments, labor intensity is large, recruitment is many, one people can only manage 2 ~ 3 mouthfuls of wells.
Summary of the invention
The object of the invention is a kind of novel water mixing heat of design and wash combination brake switch and proporting, being arranged on metering room goes on the water mixing hot clean-up well waterline of well head, the gathering and transportation technology flow process broken traditions, and well head anti-flushing well controlling functions mixed with hot water to oil return pipeline are put in metering room and complete, solve existing well site adjust mix control difficulty large, the amount of labour used is large, the problems such as labor strength is high, work under bad environment.
For achieving the above object, the technical solution adopted in the present invention is: a kind of novel water mixing heat washes combination brake switch and proporting, comprise straight-through stop valve body, overcurrent cover, valve gap, well-flushing valve rod, water mixing valve rod and pressure measuring mechanism, arrange seal valve seat in checking-valve body, the upper-end surface of seal valve seat arranges boss; Described valve gap is connected with checking-valve body sealing thread, the lower end mouth of valve gap arranges the concave station corresponding with boss, the lower end mouth of overcurrent cover and upper end-hole respectively with the boss of seal valve seat and the concave station interference fit of valve gap, overcurrent cover for oblate tubular, the uniform some vertical bar shape flowing holes of its sidewall; Described well-flushing valve rod is connected with the coaxial concentric sealing thread of above-mentioned valve gap, and the lower end of well-flushing valve rod is fixed with the flap of stopper by pin, and flap and seal valve seat form sealing pair, and handle with sleeve is fixed in the upper end of well-flushing valve rod; Described water mixing valve rod is connected with the coaxial concentric sealing thread of well-flushing valve rod, needle plug is fixed in the lower end of water mixing valve rod, and the center of above-mentioned flap has vertical through hole, and the suitable for reading of vertical through hole arranges valve piston base, form sealing pair between needle plug and valve piston base, handwheel is fixed in the upper end of water mixing valve rod; Described pressure measuring mechanism, comprises connecting tube, pressure gauge and switch valve, and described connecting tube is welded on the outlet section of checking-valve body, and the suitable for reading of connecting tube is fixedly connected with switch valve, the other end Bonding pressure table of switch valve.
Beneficial effect of the present invention:
1, facilitate production management, increase work efficiency, a people is at metering room ALARA Principle 20 ~ 30 mouthfuls of wells;
2, reed time controll watering flow, monitor individual well back pressure at any time, post workman controls water mixing and need not frequently travel to and fro between well head and metering room again, reduces recruitment and reduces labor strength;
3, open large discharge passage by well-flushing valve rod, realize clean-out service, there is a valve double-purpose functional, traditional field ground water-mixing flow assemblingization wellhead assembly can be replaced.
