Description
Technical field
The utility model belongs to oil field equipment technical field, is related to a kind of flowing well anti-clogging oil of prefilter
Mouth.
Background technology
Flowing well is the energy that oil reservoir itself is relied on by stratum energy, so that crude oil is sprayed onto ground, is called oil flow production.
In order to maintain the energy of oil reservoir that will control rate of withdrawal by atomizer, producing pressure differential is controlled.The effect of oil nozzle be control and
Adjust the quantum of output of oil well.The minimum diameter of oil nozzle is that 1.5m, maximum gauge 20mm or more are selected because of the difference of working system
Oil nozzle specification it is also different.According to oil nozzle installation position difference, two kinds of subsurface choke and surface choke can be divided into.Subsurface choke is adopted
It is mounted under oil reservoir position or oil pipe with special arrangement, surface choke is typically mounted in the oil nozzle threeway after producing gate.
Surface choke is different by structure, is divided into as single hole plain type and adjustable etc. a variety of.The most commonly used is single hole plain type atomizer, by
Crude oil in underground contains particulate contamination, and may block nozzle opening when particle appearance and size is more than the aperture of atomizer makes
It stops production at flowing well.
Authorization Notice No. is that the utility model patent of CN204486055U discloses a kind of flowing well anti-block oil nozzle, by band
The filtering silk plug in prefilter hole and the internal thread hole of oil nozzle are threadedly coupled, and are effectively reduced and are avoided sundries in oil and block oil
Mouth import ensures the unimpeded of oil gas circulation road, extends the usage time of oil nozzle, the utility model be on the basis of the patent into
One step is improved.
Utility model content
The purpose of this utility model is to provide a kind of flowing well anti-block oil nozzle of prefilter, reduces and oil well is avoided to adopt
Go out sundries in liquid and block main jet oilhole, ensures the unimpeded of oil gas circulation road, improve the performance of flowing well oil nozzle.
The technical solution of the utility model is：The flowing well anti-block oil nozzle of prefilter, including main fuel spray nozzle, main jet oil
Mouth is equipped with oil inlet, oil export and oily channel, oil inlet and is connected to oil export by oily channel.Anti-block oil nozzle is equipped with level-one mistake
Filter and secondary filter, secondary filter are the macaroni yarn bridging structure that a headband has filter hole, and the outside of secondary filter is set
There is screw thread.Grade one filter is hollow column structure, and the ring wall of hollow column and one end are equipped with filter hole, hollow column
The head thread of the other end and secondary filter with filter hole connect.The other end of secondary filter and main fuel spray nozzle into
Hydraulic fluid port is threadedly coupled.
The secondary filter of silk plug structure is equipped with six side's fastening structures.The middle part of main fuel spray nozzle is equipped with locating ring.Anti-clogging
The material of oil nozzle is carbon steel, stainless steel or alloy steel material.
The flowing well anti-block oil nozzle of the utility model prefilter has by adding grade one filter and secondary filter
Effect prevents sundries in oil well produced liquid to block main jet oilhole, ensure that the unimpeded of oil gas circulation road, extends the use of oil nozzle
Time improves the performance of flowing well oil nozzle.The utility model is simple in structure, prepares low expense, easy processing, installation operation
Conveniently and convenient for maintaining.Rate when driving a well can be improved using the utility model, increase blowing well yield.
