Abstract
A multi-stream valve for oil well is composed of valve body, valve core and its control mechanism, the inlet and outlet for flowing and measuring well stream. The valve features that its valve core can rotate while moving axially. The sealing surface at well stream inlet is conic. The sealing pressure at all sealing positions can be externally regulated. Its advantages include high sealing performance, long service life of sealing material, and simpel structure.
Description
The present invention relates to the extraordinary valve in a kind of oil field.
In oil field operation, will pursue well, regularly oil, gas, water be tested and measured by the well stream of many mouthfuls of oil gas wells production, and then the well stream of each mouthful well converges with other, is delivered to the separating treatment facility.Need the well stream of each well production is remitted management via production manifold and testing tube that all kinds of valve groups and pipeline combine for this reason.Manifold needs a large amount of valves, pipe fitting, pipeline.Arrange that loaded down with trivial details, floor space is big, troublesome poeration, be difficult to realize that electromechanical integration manages automatically again.Developed the now existing commodity of a kind of multi-stream valve [Multiport Selector Manifold abridge MSM] for this reason abroad and appeared on the market, it can substitute production manifold and test manifold work fully.But also there are some shortcomings in it: sealing surface is that the machining accuracy height of sphere, requirement, the impacting force of sealing material are guaranteed by the spring that is arranged in the valve, can not be regulated by the outside.Easy to wear and the replacing trouble of sealing material.
The object of the present invention is to provide a kind of novel multi-stream valve, it is the advantage of multi-stream valve outside the reserving state both, has overcome its shortcoming again.Its production domesticization will play a part positive to the oil gas field construction of China.This multi-stream valve is made up of the institutes such as import and export of valve body, spool, spool control mechanism, production and test well stream.It is characterized in that spool not only can do rotation motion but also axial displacement can be arranged, the sealing surface of well stream inlet is the conical surface, suffered sealing load is to regulate by being arranged on outside regulating and controlling mechanism, in addition, the impacting force of the sealing between test chamber and outside and production chamber and the test chamber is also regulated by the outside.So not only guarantee sealing but also prolonged life-span of sealing material.The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a multi-stream valve sectional elevation schematic representation, uniform eight well stream imports on the top of valve body 1, and one of them 5 walks the test well stream, and all the other seven are used to walk the production well stream.Be provided with tilt outlet 8 in the bottom of valve body 1 for producing well stream set outlet (being equivalent to produce delivery outlet outside the manifold), after well stream to be tested was come in from import 5, the test chamber 14 in spool 2 was sent to test from the outlet 6 of bottom at last.The well stream of each mouthful well converges with other again after the test, is transported in the separating treatment facility to go.The sealing surface of valve body 1 is that the conical surface 3 and 2 of spools have sealing material 4, and the impacting force between them is regulated by the spool 2 that can move down.It is protected by seal spool material hold down gag 9 and levies.Sealing material 4 and lower seal mechanism 11 have guaranteed the test well stream and have produced well stream and do not mix mutually, the production chamber 13 of 10 assurance valves of top seal mechanism and extraneous sealing, the impacting force of seal spool material hold down gag are to regulate and control by actuator's fork-like farm tool used in ancient China of spring 12 and robot control system(RCS).Fig. 2 is the plan view of multi-stream valve.
This multi-stream valve simple in structure, parts are few in addition, easy processing, cost is low, is easy to production domesticization, and the adjustability that is in operation is good, long service life, the domestic demand amount is big.Applying of it will have a positive effect to promoting China's oil gas field management modernization, after production domesticization and the formation scale, will compete with its good cost performance and external product.
Claims (2)
1, a kind of multi-stream valve is made up of the institutes such as import and export of valve body, spool, spool control mechanism, production and test well stream.The sealing surface that it is characterized in that well stream inlet is the conical surface, and the suffered impacting force of sealing material herein is to regulate by being arranged on the outer spring of valve body and the actuator of robot control system(RCS).
2, a kind of multi-stream valve as claimed in claim 1, the impacting force that it is characterized in that spool top production chamber and outside sealing and bottom test well stream and produce the sealing part of well stream also can be regulated by the outside.
