Abstract
The utility model relates to an oil and gas well high-pressure buffer spraying device, which is used in the spraying operation of oil test, gas test, major repair and minor repair in the petroleum industry and used for ensuring the continuous normal performance of the spraying operation. The spraying device comprises a throttling nozzle. A liquid inlet and a liquid outlet are arranged on a high-pressure tee joint, wherein the throttling nozzle is mounted in the high-pressure tee joint opposite to the liquid inlet, and a spraying buffer is mounted on the high-pressure tee joint opposite to anther end of the throttling nozzle. The spraying buffer is mounted on the back end of the high-pressure tee joint to effectively weaken the impact force of the high-pressure fluid and effectively protect the downstream device of the spraying device. A filter pipe with the diameter of an aperture being not larger than the diameter of the throttling nozzle is added before the throttling nozzle, the sprayed sundries are prevented from blocking up the throttling nozzle. After the jet energy is weakened, the direction of the fluid is changed by the spraying buffer and the high-speed fluid is split by a corrosion resistant inner liner pipe, so as to effectively weaken the impact energy of the fluid, ensure the safety of the downstream device and increase the service life of the spraying device.
Description
Technical field
The utility model relates to the high pressure open flow device of petroleum industry oil gas well, particularly oil gas well high-pressure buffer open flow device, is used for the open flow operation of formation testing, gas testing, overhaul, light maintenance, and the work of assurance open flow is normally carried out continuously.
Background technology
Along with oil field development is goed deep into, increasing well need carry out pressure break, or even large-scale pressure break, is to guarantee normally carrying out continuously of open flow operation, and it is particularly important that the functional reliability of open flow oil nozzle seems.Present used open flow flow nipple anti-wear performance is poor, if formation sand production, under certain pressure, flow nipple will soon be big by thorn, and effect is undesirable, can not guarantee that the open flow operation normally carries out continuously.
Summary of the invention
The purpose of the utility model provides oil gas well high-pressure buffer open flow device; Weaken the impact energy of high-pressure fluid; Improve the erosive wear resistance of open flow flow nipple and the anti-high-voltage performance of open flow device, open flow work can normally be carried out continuously, guarantee the safety of open flow device upstream device.
The present technique solution can reach above-mentioned purpose: oil gas well high-pressure buffer open flow device comprises flow nipple; On Highpressure Tee, be provided with inlet and liquid outlet; Flow nipple dashes inlet is installed in the Highpressure Tee, on Highpressure Tee, dashes another port of flow nipple is installed the open flow snubber.
Compared with prior art, the utlity model has following useful effect: the interior cover of the utility model flow nipple is that wear-resistant, anti-erosion material is processed, and uses special tool replaceable.In the back port of Highpressure Tee the open flow snubber has been installed, can have effectively been weakened the impact force of high-pressure fluid, effectively protected the safety of open flow device upstream device.Set up the filter pipe that eyelet is not more than the flow nipple diameter before the flow nipple, prevent that the foreign material that open flow goes out from stopping up flow nipple.The open flow snubber is employed in and weakens the flow direction that changes fluid behind the jet energy again, utilizes the erosion resistant internal lining pipe that high-velocity fluid is shunted, and can effectively weaken the impact energy of fluid, guarantees the safety of upstream device, improves the application life of device.This apparatus structure is simple, effect is obvious, the open flow operation that can guarantee the oil gas well continuously, normal, have tangible economic and social benefit.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing; Oil gas well high-pressure buffer open flow device; Comprise flow nipple 3; On Highpressure Tee 4, be provided with inlet 1 and liquid outlet 6, flow nipple 3 dashes inlet 1 is installed in the Highpressure Tee 4, on Highpressure Tee 4, dashes another port of flow nipple 3 is installed open flow snubber 5.Open flow snubber 5 comprises outer tube, interior pipe 7, internal lining pipe 8 and screen casing 9, and the cylindrical of interior pipe 7 is provided with wiper block, internal lining pipe 8 is housed in the interior pipe 7, its rear end is connected with screen casing 9; With interior pipe 7 outer tube of packing into after the assembling, the outer tube front end connects Highpressure Tee 4, and blind plate and blocking cap are installed in the rear end.In the wiper block of pipe 7 cylindricals be provided with at interval around the cylindrical of interior pipe 7, pipe 7 is placed in the middle, stable in guaranteeing, and stays passage for the buffering hydrocarbon fluids that refluxes.The front end and the rear portion of pipe 7 were provided with two places at least in the wiper block of interior pipe 7 cylindricals was arranged on, and improved and set upright effect.Inlay cover in the erosion resistance in the endoporus of flow nipple 3, use special tool can change cover in this erosion resistance, practice thrift cost.The front end mounting filtering pipe 2 of flow nipple 3 prevents that impurity from stopping up flow nipple 3.
During open flow, inlet 1 place of this device Highpressure Tee 4 adopts the open flow outlet of screwed connection at oil gas well well head, and hydrocarbon fluids gets into from inlet 1, behind filter pipe 2, flow nipple 3, gets into open flow snubber 5.Fluid gets into the back from internal lining pipe 8 and flows out from screen casing 9; Return out the annular space between interior pipe 7 and outer tube; Flow in the relief line from liquid outlet 6, the fluid after changing jet direction and reducing the fluid jet energy can not have a negative impact to the equipment at relief line rear portion.
