The specific embodiment
Application principle of the present invention, effect and effect are explained through following embodiment with reference to accompanying drawing 1-3.
A kind of crystallization prevention control device for high temperature brine of the present invention is made up of well casing 1, valve body 9, spool 3, spring 4, valve seat 8 and jam pot cover mouth 5, and well casing 1 communicates with valve pocket 7; Its top links to each other with lifting appliance; And cavity wall axial sliding fit on its outer wall and the valve body 9, valve seat 8 are hollow structure among the upper and lower opening, and its cavity and valve pocket 7 connect; Valve seat 8 is fixed in valve body 9 bottoms through jam pot cover mouth 5; Being located on the cannular boss at valve seat 8 centers of spring 4 to the lower surface, it joins to upper surface and spherical valve core 3, and the hypomere of well casing 1 is provided with some circular pod apertures 6.The external diameter of spherical valve core is slightly larger than the internal diameter of well casing 1 hypomere, the external diameter of spring 4 and the internal diameter of valve seat 8 upper surfaces.The last top of chamber of valve body 9 is up big and down small inner conical surface 10.Pod apertures is located at well casing 1 hypomere, and when spring 4 was between the minimax compression travel, pod apertures was positioned at valve pocket 7.
Consult accompanying drawing 1, the mouth of pipe of well casing 1 props up spherical valve core 3, spherical valve core 3 to lower compression spring 4 to the minimum stroke place, this moment spherical valve core 3 with the boss close proximity of valve seat 8, close the internal orifice of valve seat 8, then down-hole bittern is blocked, the bittern well shutting in.This is the following closed condition of this control device.
Consult accompanying drawing 2, when needs drove a well, it was up to promote well casing 1 through surface drive; Spherical valve core 3 is also along with the thrust of compression spring 4 is upwards moved; When reaching correct position, stop to promote well casing 1, this moment, pod apertures 6 was positioned at valve pocket 7; High-temperature bittern gets into well casing 1 inner chamber through pod apertures, and carries earthward.
Consult accompanying drawing 3; When on needs use, closing mode, it is up to promote well casing 1 through surface drive, and spherical valve core 3 is also along with the thrust of compression spring 4 is upwards moved; Be in the range place until compression spring 4; Spherical valve core 3 is withstood on the top sealing part of valve pocket 7, and bittern was mended and was blocked the bittern well shutting in this moment.
When the bittern well need close the stopping time; It is up to promote well casing 1 through surface drive, gets into valve body inner conical surface 10 regions or is higher than 2 regions, valve body upper surface until the lower end of well casing 1, and compression spring 4 is in the range place; Spherical valve core 3 is withstood on the top sealing part of valve pocket 7; This moment, bittern was blocked, and the bittern well shutting in can clean with clear water etc. pipeline and the cavity of spherical valve core more than 3; Discharge the bittern water of high-temperature high concentration wherein, avoid static bittern water to reduce post crystallization and solidify and blocking pipe in temperature.
Simultaneously because this control device is installed in the down-hole; And be arranged at top, high temp. salt bittern source; High temp. salt bittern in the valve pocket 7 can Yin Wendu not be crossed low and crystallization takes place and is solidified, thereby guarantees that this control device faults such as bittern water crystallization and freezing and blocking pipe can not take place.
After closing down, need drive a well again, then only need make well casing 1 descending through surface drive, compression spring 4 be descending under the effect of well casing 1; Spherical valve core 3 is also along with compression spring 4 moves downwards; When reaching correct position, the well casing 1 that stops to descend makes pod apertures 6 be positioned at valve pocket 7; High-temperature bittern gets into well casing 1 inner chamber through pod apertures, and carries earthward.
From the above; A kind of crystallization prevention control device for high temperature brine of the present invention; Can prevent effectively that high-temperature bittern is at the well casing intercrystalline; Stop up well casing, have simultaneously and can directly drive a well again after closing down, needing to have avoided the removing of labor human and material resources and time to be jammed in the plurality of advantages such as operation of the interior a large amount of bittern crystallizations of well casing.
