Abstract
The utility model provides an isotope tracer safety injector including an injector casing, and the injector is characterized in that the injector casing is composed of a stainless steel cavity, a sealing plug being capable of tightly combined with the casing, an extrusion rod, and a screen mesh, a rubber sealing ring is arranged on the sealing plug, the extrusion rod is fixed on the sealing ring by means of a jack screw, and the screen mesh is arranged at the bottom of the stainless steel cavity. The safety injector provided is advantageous in that 1. the non-open operation of the isotope tracer is realized to ensure the safety of environment and personnel; 2. the injector provided can be normally used under the on-site temperature ranging from -30 DEG C to 50 DEG C; 3. the bearing pressure of the whole system is not less than 60MPa, thus, leakage phenomenon can be prevented; 4. because a plurality of Phi 3 small holes are drilled in the bottom and the circumferential wall of the screen mesh, the isotope fluid can flow out and the glass fragments are left in the mesh to prevent the system pipeline from being blocked due to the flow-out of the glass fragments, thereby keeping the gate being unblocked.
Description
(1) technical field
The utility model relates to the servicing unit in a kind of isotopic tracing determination in well process, particularly a kind of isotopic tracer safety injector.
(2) background technology
In the research and development of tagging inter-well test project, an important step is to hope and can isotopic tracer safety be injected in the wellhole smoothly.At present, the injection of isotopic tracer is by injecting water pressure, carries tracer and gets into pit shaft; General water injection pressure is at tens MPa; Therefore whole injection technology system no seepage and no leakage under so big pressure is difficult to realize, and operating process is open when injecting isotope in the field operation; Often cause environment pollution, operating personnel's health also is on the hazard.Inventing a device that can make isotopic tracer realize that safety is injected is the new problem that research and development design.
(3) summary of the invention
The purpose of the utility model is to design a kind of isotopic tracer safety injector, to solve the problem that isotopic tracer safety is injected.
The technical scheme of the utility model: a kind of isotopic tracer safety injector; Constitute by the injector casing; It is characterized in that: sealing-plug that its injector casing can be combined closely with it by a stainless steel cavity and and pressure ram and screen cloth constitute; On sealing-plug, be provided with rubber seal, pressure ram is fixed on the sealing ring by jackscrew, and screen cloth is arranged at the stainless steel cavity bottom.
Aforesaid pressure ram just in time is positioned at screen cloth inside, and it combines with screen cloth closely, and can be free to slide.
At the bottom of the aforesaid screen cloth, Side wall drill is equipped with intensive φ 3 sieve apertures.
Constitute radioisotope unit between aforesaid pressure ram and the screen cloth.
Aforesaid stainless steel cavity is provided with inlet valve and injects valve, is connected with pipeline.
The sealing means of " O " cushion rubber is adopted in the sealing-plug design of aforesaid airtight injection container, and high pressure valve and high-pressure hose line are adopted in other coupling part.
The superiority of the utility model: 1, realized the no open operation of isotopic tracer, guaranteed environment and personal security; 2, this equipment can normally use under-30 ℃～+ 50 ℃ field conditions; 3, the whole system pressure-bearing is not less than 60MPa, no seepage and no leakage; 4, owing to bore on the end of screen cloth and the perisporium and beat a plurality of φ 3 apertures, the isotope fluid can flow out, and glass fragment stays in net, avoids glass fragment to flow out the block system pipeline, and the maintenance gate is unimpeded.
(4) description of drawings
Accompanying drawing is the structural representation of the utility model, wherein:
1, stainless steel cavity, 2, sealing-plug, 3, pressure ram, 4, screen cloth, 5, rubber seal, 6, sieve aperture, 7, radioisotope unit, 8, inlet valve, 9, inject valve, 10, jackscrew, 11, pipeline.
(5) specific embodiment
As shown in the drawings: a kind of isotopic tracer safety injector; Constitute by the injector casing; It is characterized in that: its injector casing is made up of with screen cloth 4 a stainless steel cavity 1 and a sealing-plug 2 and the pressure ram 3 that can combine closely with it; On sealing-plug 2, be provided with rubber seal 5, pressure ram 3 is fixed on the sealing ring 2 by jackscrew 10, and screen cloth 4 is arranged at stainless steel cavity 1 bottom.
Aforesaid pressure ram 3 just in time is positioned at screen cloth 4 inside, and it combines with screen cloth 4 closely, and can be free to slide.
4 ends of aforesaid screen cloth, Side wall drill are equipped with intensive φ 3 sieve apertures 6.
Constitute radioisotope unit 7 between aforesaid pressure ram 3 and the screen cloth 4.
Aforesaid stainless steel cavity 1 is provided with inlet valve 8 and injects valve 9, is connected with pipeline 11.
The sealing means of " O " cushion rubber is adopted in sealing-plug 2 designs of aforesaid airtight injection container, and the valve of other coupling part adopts high pressure valve and high-pressure hose line.
When isotopic tracer safety injector uses; With individual (vial encapsulation) screen cloth of packing into of the isotope through sealing of production and supply, sealing-plug drives pressure ram, and the isotope vial is crushed; Isotope liquid discharges, and squeezes into the injection pit shaft with injecting water through system; Because the end and the perisporium of screen cloth are provided with a plurality of φ 3 apertures, the isotope fluid can flow out, and glass fragment stays in net, avoids glass fragment outflow block system pipeline valve unimpeded.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
