Description
Cross reference to related applications
This application claims the U.S. Provisional Application No.62/019 that on July 1st, 2014 submits, 566 equity, by helping
Draw and is incorporated herein.
Technical field
The disclosure relates generally to balanced valve (dummy valve).More specifically, in certain embodiments, the disclosure relates to
And hydraulic locking compensation balance valve and relevant method and system for gaslift.
Background technique
Gas-lift well has just used since 19th century, and has been proved to especially suitable for the natural lifting force in reservoir
Increase effective tar productivity in insufficient situation.In general, the natural gas generated in oil field is compressed simultaneously in gaslift oil well
And by the annular space between sprue bushing and oil pipe, and it is directed into oil pipe from casing to be provided to oil pipe fluid column
" lift " is for making oil-producing go out from oil pipe.Although oil pipe can be used for injecting lift gas and annular space can be used for oil-producing, this
It is rarely found in practice.
A kind of gas-lift well use of common type is attached to the Wave Machine tubular type gas lift valve of oil pipe, to adjust from annular empty
Between into tubing string gas flowing.The example of this gas lift valve is retouched in United States Patent (USP) No.5,782,261 and 5,425,425
It states, entire contents are incorporated herein by reference.In typical bellows-type gas lift valve, bellows is preset or is charged in advance one
Constant-pressure, thus the valve make it possible under Preliminary pressure-filled flow out annular space with entrance oil pipe gas connection.Often
Position, pressure head, the physical condition of underground and various other factor of the pressurising of a valve by oil well engineer according to valve in well
It selects, it is some assuming that or unknown in these factors, or will change during the Production Life of well.
Other types of gas-lift well is in United States Patent (USP) No.6,715,550 and U.S. Patent Application Publication No.2014/
It is described in 0041863, entire contents are incorporated herein by reference.There are also other kinds of gas-lift wells to use balanced valve.It is this
It is described in United States Patent (USP) No.8,162,060 using the example of the gas-lift well of balanced valve, entire contents are incorporated by reference into this
Text.
Double bellows side-pocket mandrels (side pocket mandrel) are generally used in offshore well, desired or requirement
, must not exist between oil pipe and annular space during the movement of gas lift valve intervention and be connected to.Double bellows seating nipples make it possible to
The gas lift valve of enough pull operation, stays in appropriate location for barrier isolating valve at the same time, so that at this time oil pipe can be connected
Lead to annulus.By the movement that operation valve pulls out in the capsule of seating nipple from it can enable to by oil pipe liquid introduce valve capsule with
And it is introduced into the space between operation valve and barrier isolating valve.Once operation valve is replaced by traditional balanced valve, then may deposit
The hydraulic locking the problem of.Since balanced valve is pushed into its capsule by its minimum packing elements group, it is captured at this time
The incompressible fluid in space between barrier isolating valve and balanced valve may prevent the remainder of balanced valve from
It is enough driven in its capsule.Traditional balanced valve does not handle the means of the captured fluid.
It is expected that developing a kind of balanced valve, being able to maintain and handling the fluid being trapped between each capsule.
