This ground water mixing filter equipment is including filter screen and ring flange. Jar be equipped with water inlet and delivery port on the body, the top is equipped with relief valve and manometer, goes up that the blowoff valve is established on the upper portion of the jar body, the export setting of blowoff valve is in the bottom of the jar body down, and the delivery port welds at the middle part of blind flange, and the filter screen is fixed in the inboard of delivery port, passes through bolted connection with blind flange and ring flange. This device simple structure, simple to operate. The relief valve and the manometer of tank deck installation, pressure release safety protection is transshipped for the device provides pressure to convenient the observation. The scale deposit that alleviates water mixing hollow bar inner wall is blockked up, is convenient for discharge simultaneously daily management such as greasy dirt and change, clearance filter screen again and maintains, alleviates worker's intensity of labour.
Description
Technical field
The utility model belongs to the ground auxiliary device of oil-field thick-oil well hollow rod water-doped, particularly a kind of heavy oil wells hollow stem ground watering filter, can by water mixing process from contaminant filters such as the greasy filth in pipeline between water mixing, the water quality of water is mixed in purification.
Background technology
Heavy oil wells hollow stem adding water over pumps takes out thick leading technique, and a larger heavy oil block, its water mixing well station can reach tens, water mixing oil well hundreds of mouth, day watering quantity several thousand m3.Because water quality is not up to standard, the serious consequences such as the blocking of water mixing pipeline, hollow stem fouling and greasy filth blocking can be caused.Cause individual well water mixing pressure to rise to 2MPa, 3MPa gradually by the 1-1.5MPa at initial stage, even reach the 4MPa maintained an equal level with dry-pressing.If watering quantity does not reach requirement, water-doped viscosity reduction effect is affected, and causes bar to block up, break well of lying of bar presents the trend increased year by year.Because of bar break, bar blocks up the workover treatment caused and rises year by year, badly influenced that normal steady oil is upper to be produced, and causes the significantly increase safeguarding well operations cost.If improve water quality by transformation water mixing system, be then systematic engineering of business, demand fund is huge.For solving quality problem, by the basket filter be arranged on water mixing main line, water quality is purified.This basket filter is provided with adpting flange, screen pack, housing and gland.Due to water mixing main line by Flange joint on main line, limit the volume of basket filter to a certain extent, contain dirty ability and be extremely restricted.The filter screen particularly wherein installed is generally steel filter net, due to perishable, blocking, does not have again convenient sewage draining exit, change, clear up filter screen difficulty, worker's labour intensity is large, easily causes environmental pollution, can not meet maintenance requirement, is not suitable for production scene use.For this reason, a kind of Novel filter device is needed to solve the problem.
Summary of the invention
The utility model is for above-mentioned heavy oil wells hollow rod water-doped present situation, a kind of heavy oil wells hollow stem ground watering filter is provided, effectively filter and sedimentation from the defeated water that mixes between water mixing, facilitate blowdown and daily management, the maintenance work such as replacing, cleaning filter screen, alleviate the labour intensity of worker, improve the water quality of mixing water, thus reduce workover treatment cost.
Technical solution of the present utility model is:
A kind of heavy oil wells hollow stem ground watering filter, comprises filter screen and ring flange.Tank body is provided with water inlet and delivery port, top is provided with safety valve and Pressure gauge, scum valve is located at the top of tank body, the outlet of down blow valve is arranged on the bottom of tank body, delivery port is welded on the middle part of blind flange, filter screen is fixed on the inner side of delivery port, blind flange and ring flange is bolted.
Be provided with sedimentation chamber in the tank body of described water inlet side, sedimentation chamber is provided with sedimentation diaphragm plate and vertical clapboard, and sedimentation diaphragm plate is provided with sedimentation hole, and the height of vertical clapboard is lower than the height of tank deck, and water inlet is located between two pieces of sedimentation diaphragm plates; Filter screen is supported by screen casing, is welded by screen casing with delivery port.
The beneficial effects of the utility model are: this apparatus structure is simple, easy for installation.The safety valve that tank deck is installed and Pressure gauge, convenient observation, for device provides pressure overload pressure release safeguard protection.Destruction to watering pipe network when preventing the pressure caused because of filter net jam, throttling etc. from exceeding water mixing rated operating pressure.This device can be connected mutually, can install the filter screen of different filtering accuracy in each tank body, thus forms multistage filtering.Filter screen is the corrosion-resistant PE resin strainer of heatproof more than 120 DEG C, is sleeved on outside screen casing, to water mixing filtration.Device and water mixing pipeline, are effectively filtered and sedimentation water between water mixing by clamp connection on water mixing pipeline, improve the water quality of mixing water.Alleviate the fouling and clogging of water mixing hollow stem inwall, be convenient to again discharge greasy dirt and the daily management such as replacing, cleaning filter screen maintenance simultaneously, alleviate the labour intensity of worker.
