Description
Technical field
The utility model relates to field of petroleum exploitation, belongs to the control appliance of Produced Liquid flow, particularly a kind of quick-replaceable oil nozzle turn ball formula resistance oil nozzle sleeve device.
Background technology
In oil extraction process, generally use oil pumper to recover the oil, in order to improve the benefit of gathering, need to control oil recovery well yield, generally adopt oil nozzle to carry out Flow-rate adjustment.
Along with the sustainable development of oil recovery technique, the ratio of occupying of heavy oil wells improves constantly.At present, heavy oil wells exploitation generally adopts " steam soak method ", through processes such as " steam injection, stewing well, blowings, turn and take out ", underground viscous crude is implemented to desaturation processing, to improve crude output, reduces production costs.In whole process, need to adjust accurately, timely oil nozzle latus rectum, throttling open flow is asked product; Simultaneously effectively extend the oil well blowing cycle, reach and make full use of heat energy and increase oily object, protection stratum.
In oilfield exploitation procedure, conventionally adopt oil nozzle control Produced Liquid flow (in GB/T22513-2008 " industrial gas oil drilling well and oil production equipment wellhead assembly and production tree ", to be defined as " choke valve ", be flow regulator, be called traditionally " resistance oil nozzle sleeve " or " oil nozzle ").By regulating oil nozzle latus rectum size, control oil recovery pressure reduction, steadily reasonably control output, realize the scientific management to oil well production situation.
At present, use the most generally fixed choke cover.Be connected with resistance oil nozzle sleeve screw-internal thread fit by oil nozzle external screw thread, realize different current limliting requirements by the oil nozzle of changing different size aperture.But there are the following problems:
1. in steam injection or turn and take out etc. need to change oil nozzle time, can only closing well, pull down resistance oil nozzle sleeve end cap after release and change positive choke, waste time and energy, bring inconvenience to oil recovery scene.
2. while changing oil nozzle at every turn, have pipe inner fluid and flow out, easily cause crude oil pollution.
3. labour intensity is large, and holding time is long, and often freezes winter, affects benefit.
Utility model content
What the purpose of this utility model was to provide a kind of quick-replaceable oil nozzle turns ball formula resistance oil nozzle sleeve device, and it is rational in infrastructure, in the time changing oil nozzle; need not shutdown operation, i.e. replaceable oil nozzle can not cause crude oil to flow out in demolition, installation oil nozzle process; protection of the environment, easy and simple to handle, time saving and energy saving.
What the purpose of this utility model was achieved in that a kind of quick-replaceable oil nozzle turns ball formula resistance oil nozzle sleeve device, comprise that axle center has the resistance oil nozzle sleeve matrix of pore, spherical cavity is being set in resistance oil nozzle sleeve matrix, the centre of sphere of spherical cavity is positioned on the axis of resistance oil nozzle sleeve matrix pore, and at the resistance oil nozzle sleeve basal body pipe hole wall of spherical cavity radius and the perpendicular side of axis, dismounting hole is being set, in spherical cavity, coordinate the spherical resistance oil nozzle sleeve that center is installed has through hole, one end at through hole is installed with tubulose oil nozzle by screw thread, six side's counterbores or dismounting groove in the outer end of tubulose oil nozzle pore is arranging.
In the utility model resistance oil nozzle sleeve matrix, spherical cavity is being set, in spherical cavity, coordinate to be installed with and turn ball formula resistance oil nozzle sleeve, turn in ball formula resistance oil nozzle sleeve and have through hole, self can rotate, between resistance oil nozzle sleeve matrix and resistance oil nozzle sleeve, keep sealing state, the fluid in resistance oil nozzle sleeve matrix through hole can only flow by resistance oil nozzle sleeve endoporus.Oil nozzle aperture can process as requested, and resistance oil nozzle sleeve and oil nozzle are threaded connection.There are interior six side's counterbores in oil nozzle pore one end or tighten the structures such as groove, can rotate demolition, installation oil nozzle by use instrument.Oil nozzle body has a dismounting hole in flow direction side.
Replace the choke valve of installing on production tree with the utility model, when the utility model work:
One, throttling duty:
1, turn in ball formula resistance oil nozzle sleeve and have through hole, turn ball formula resistance oil nozzle sleeve, make through hole consistent with resistance oil nozzle sleeve matrix through hole direction;
2, owing to keeping sealing state between resistance oil nozzle sleeve matrix and resistance oil nozzle sleeve, the fluid in resistance oil nozzle sleeve matrix through hole can only flow by resistance oil nozzle sleeve and oil nozzle endoporus, thus the throttling action of realization.
Two, dismounting oil nozzle:
1, without stopping production, directly resistance oil nozzle sleeve is turned an angle, make oil nozzle forward dismounting hole site to;
2, use kit, probe into dismounting hole, i.e. the oil nozzle in replaceable appropriate bore footpath.
The utility model is rational in infrastructure, and changing when oil nozzle, having realized need not shutdown operation, i.e. replaceable oil nozzle can not cause crude oil to flow out in demolition, installation oil nozzle process, and protection of the environment is easy and simple to handle, time saving and energy saving.
