Abstract
The utility model relates to a site anti-contamination device convenient to demount and used for an oil field, in particular to an ultrahigh pressure nitrogen injection composite manifold. The ultrahigh pressure nitrogen injection composite manifold comprises two four-way connectors and two three-way connectors, wherein the two four-way connectors and the two three-way connectors are arranged symmetrically, the two four-way connectors are mutually connected through an interface of each of the two four-way connectors, the two three-way connectors are mutually connected through an interface of each of the two three-way connectors, and the two four-way connectors are connected with the other interface of each of the two three-way connectors through the other interface of each of the two four-way connectors; air inlet valves are installed on remaining two interfaces of each the two three-way connectors; a decompression valve is installed on a remaining interface of one of the two three-way connectors; and an air outlet valve is installed on a remaining interface of the other of the two three-way connectors. According to the ultrahigh pressure nitrogen injection composite manifold, a mode of 'four air inlets, one air outlet and one air discharge' is adopted, simultaneous nitrogen injection, of four sets of nitrogen injection equipment, into a wellhead can be achieved, and a needle valve is used for flow regulation, decompression and flow opening when pressure of a wellhole is excessively high.
Description
Technical field
The utility model relates to the oil field and uses the oil tool field, is specially a kind of super-pressure nitrogen and injects compound manifold.
Background technology
At present, what superelevation pressure injection nitrogen equipment used is thousand type well head production trees, adopts production tree to have following problem, 1, can't connect when multiple devices inject simultaneously.2, completion or not easy to operate during pressure release midway.3, the damage that is prone to gate board of the long-term high pressure injection nitrogen of well head causes the accident.
The utility model content
For above-mentioned technological deficiency, the utility model provides a kind of super-pressure nitrogen of reasonable in design, safety and stability to inject compound manifold.
Its technical scheme is: comprise two four-ways and two threeways of being arranged symmetrically with, wherein two four-ways interconnect by an interface on it, two threeways interconnect by an interface on it, and two four-ways are respectively by another interface in two threeways of another interface connection on it; Two four-ways are installed into air valve on remaining two interfaces respectively, on the interface of one of them threeway remainder, relief valve are installed, and on the interface of another threeway remainder, air outlet valve are installed.
Such scheme can further be improved to:
Interface between described any two threeways, four-way is equipped with valve on connecting.
The threeway of described installation air outlet valve is provided with pressure meter.
Compared with prior art, the utility model has following technological merit:
1, can realize multiple devices injection in parallel, adapt to the polytropy of technique.
2, convenient midway or the pressure release in complete man-hour.
3, the convenient adjusting injected discharge capacity.
4, have more safety, play the function that auxiliary blowout prevention and multiple fluid are injected.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of utility model;
In figure: 1.1-1.2, four-way, 2.1-2.2, threeway, 3, air inlet port, 4, pressure relief opening, 5, the gas outlet, 6, needle valve, 7, pressure meter.
The specific embodiment
Be described further with reference to 1 pair of the utility model of accompanying drawing:
A kind of super-pressure nitrogen injects compound manifold, comprise two four-ways 1.1 being arranged symmetrically with, 1.2 and two threeways 2.1,2.2, wherein two four-ways 1.1,1.2 interconnect by an interface on it, two threeways 2.1,2.2 interconnect by an interface on it, and two four-ways 1.1,1.2 connect another interface in two threeways 2.1,2.2 by another interface on it respectively; Two four-ways 1.1,1.2 remaining two interfaces respectively respectively as air inlet port 3, are installed into air valve on it, the interface of one of them threeway remainder is as pressure relief opening 4, needle valve 6 is installed on it, setting pressure table 7 in another threeway, and remaining interface is installed air outlet valve as gas outlet 5 on it.Interface between any two threeways, four-way is equipped with valve on connecting.
The technology path that the utility model is taked is to adopt a kind of brand-new injection-gas manifold, alters the connection gas injection with production tree.This brand-new injection-gas manifold adopt " four advance one to go out and one put " and mode, can satisfy quadruplet and annotate nitrogen equipment simultaneously to the well head gas injection, and when wellbore pressure is too high, come adjust flux by needle valve, carry out pressure release and open flow.A whole set of injection-gas manifold is made of valve, four-way, threeway and pressure meter, and is main by opening and closing valve in gas injection process, controls gas injection pressure and gas flow.During gas injection, close the needle valve of pressure relief opening, open other valve, quadruplet equipment while this moment makes pressure reach the highest to the well head gas injection, also can regulate according to actual conditions, uses a cover or two covers or three cover notes nitrogen equipments to carry out Site Service.When finding that wellbore pressure is too high, can close other gas injection valve, open needle valve, regulate the gas of well head open flow and pressure and the uninterrupted of liquid by needle valve, in time pressure release.
For those skilled in the art, under the prerequisite that does not break away from the utility model principle, might make some improvements and modifications to partial structurtes, these improvements and modifications also should be considered as protection domain of the present utility model.
