Abstract
The utility model relates to a non-stop production changeable well mouth check valve device which comprises a left valve, an upper three-way pipe, a right upper valve, a check valve, a valve joint, a right lower valve and a lower three-way pipe, wherein the upper three-way pipe comprises three through ports, the through port on the left side of the upper three-way pipe is connected with the left valve, the lower three-way pipe comprises three through ports, the left valve is connected with the through port on the left side of the lower three-way pipe, the through port on the right side of the upper three-way pipe is connected with the right upper valve, the right upper valve, the check valve, the valve joint and the right lower valve are sequentially connected, the right lower valve is connected with the through port on the right side of the lower three-way pipe, a pressure release port is arranged on the side surface of the valve joint, the upper part of the check valve is connected with the right upper valve through an oil term, and the lower part of the check valve is connected with the valve joint through the oil term. When the check valve needs to be replaced after being damaged, stop production of an oil well is not required, loss of the yield of the oil well is avoided, well workover operation caused by sticking of a pump due to sand settling during the replacement of the check valve can also be avoided, and the non-stop production changeable well mouth check valve device further has significant economic benefits.
Description
Technical field:
The utility model relates to the device that the oil field pumping well well head is used, and is that a kind of the stopping production can be changed well head ball-and-seat device.
Background technology:
In oilfield, when oil well stopped well for some reason, in the interior extraction liquid of oil pipe can flow backwards Hui Jing on the oil well pump, when pipeline rupture on the oil well pump was missed, the extraction liquid on the oil well pump in the oil pipe also can flow backwards in the Hui Jing.Extraction liquid can flow backwards, and causes production loss on the one hand, also can cause the ground damage layer on the other hand, therefore; Need be at pumpingh well floor mounted ball-and-seat, but the design of present ball-and-seat is unreasonable, damages easily, and application life is short; The damage back needs to stop production when changing, and reduces oil well output, for sand well, after ball-and-seat is changed in stopping production; Sand on the pump in the oil pipe can sink, and causes holddown, causes workover rig service to oil well, causes heavy economic losses.
Summary of the invention:
The purpose of the utility model is that a kind of stopping production of design can be changed well head ball-and-seat device, does not need oil well to stop production when changing ball-and-seat, avoids because of changing the economic loss that ball-and-seat stops production and brings.
The purpose of the utility model is achieved in that and comprises left valve, last tee piece, upper right valve, ball-and-seat, Valve joint, bottom right valve, following tee piece; Last tee piece has three ports; Last tee piece left side port is connected with left valve, and following tee piece has three ports, and left valve is connected with the left side port of following tee piece; Last tee piece right side port is connected with upper right valve; Upper right valve, ball-and-seat, Valve joint, bottom right valve connect successively, and the bottom right valve is connected with the right side port of following tee piece, and the Valve joint side is put and pressed mouth.
Ball-and-seat top adopts oil to be connected the ninth of the ten Heavenly Stems with upper right valve, and the ball-and-seat bottom adopts oil to be connected the ninth of the ten Heavenly Stems with Valve joint.
The beneficial effect of the utility model is: when after ball-and-seat damages, needing to change, do not need oil well to stop production, oil well is lost units not, also can not occur causing sand sinking holddown to cause workover treatment because of changing ball-and-seat, has remarkable economic efficiency.
Description of drawings:
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment:
Below in conjunction with Fig. 1 the utility model embodiment is described.
Can know by figure; The utility model embodiment comprises left valve 1, goes up tee piece 2, upper right valve 3, ball-and-seat 4, Valve joint 5, bottom right valve 7, tee piece 8 down, and last tee piece 2 has three ports, and last tee piece 2 left side ports are connected with left valve 1; Following tee piece 8 has three ports; Left side valve 1 is connected with the left side port of following tee piece 8, and last tee piece 2 right side ports are connected with upper right valve 3, and upper right valve 3, ball-and-seat 4, Valve joint 5, bottom right valve 7 connect successively; Bottom right valve 7 is connected with the right side port of following tee piece 8, and Valve joint 5 sides are put and pressed mouth 6.Ball-and-seat 4 tops adopt oil to be connected the ninth of the ten Heavenly Stems with upper right valve 3, and ball-and-seat 4 bottoms adopt oil to be connected the ninth of the ten Heavenly Stems with Valve joint 5.
Last tee piece 2 upper ports are connected with production tree, and following tee piece 8 lower ports are connected with back pressure valve on the flow line.Close left valve 1 during ordinary production, open upper right valve 3, bottom right valve 7, produce oil is through last tee piece 2 upper ports, upper right valve 3, ball-and-seat 4, Valve joint 5, bottom right valve 7, tee piece 8 lower ports flow out down.When needing to change, open left valve 1 earlier, close upper right valve 3, bottom right valve 7 because of ball-and-seat 4; Beat opening pressure mouth 6; Bleed off the pressure in the ball-and-seat 4, change ball-and-seat 4 then, because ball-and-seat 4 tops adopt oil to be connected the ninth of the ten Heavenly Stems with upper right valve 3; Ball-and-seat 4 bottoms adopt oil to be connected the ninth of the ten Heavenly Stems with Valve joint 5, so change easily.At this moment, produce oil is through last tee piece 2 upper ports, left valve 1, tee piece 8 lower ports outflow down.
After change accomplishing, and close to put and press mouthfuls 6, open upper right valve 3, bottom right valve 7, close left valve 1 again, the oil well ordinary production, ball-and-seat 4 need not stop production.
