Abstract
The invention relates to an oil-water well eccentricity rectification liquid conveying device which is mainly used for a testing process of an oil-water well which needs multiple-channel flow passing. The oil-water well eccentricity rectification liquid conveying device comprises an outer cylinder and an eccentric pipe. The eccentric pipe is arranged in the outer cylinder. A hung inner shoulder is arranged in the outer cylinder. A hung outer shoulder is arranged at the upper end of the eccentric pipe. The hung outer shoulder is not coaxial with a main channel. An axial side flow channel is arranged on the hung outer shoulder. The hung outer shoulder is hung on the hung inner shoulder. Because of adoption of a double-layer tube eccentricity hanging structure, the oil-water well eccentricity rectification liquid conveying device can penetrate through continuous oil pipes, and also can rectify the eccentricity of a tool tightly connected with the upper portion of the device, and meanwhile, the oil-water well eccentricity rectification liquid conveying device is provided with double flow channels to convey formation fluids.
Description
Technical field
The present invention relates to a kind of test kit in oil field development, concretely it is that a kind of oil-water well bias is reformed biography
Liquid device, is mainly used in the oil water well test technique for need multichannel excessively stream.
Background technology
Oil field development enters middle and late stage, and what the horizontal well of early stage large-scale application occurred that oil content gradually reduces successively asks
Topic, is to solve problems, and the analysis that conducts a research understands that its production profile is just particularly important.Cut open in R ＆ D Level well output
During the test technique of face, a kind of such instrument is needed, it can pass through coiled tubing, the instrument that can be close to top again
Bias is reformed naturally, while also formation fluid will be transmitted with dual channel.But existing instrument is all without this specific function, it is impossible to full
The rigors of foot special project test technology.
The content of the invention
To solve the above problems, a kind of oil-water well bias is invented and has reformed biography liquid device, the instrument can be through continuous oil
Pipe, the bias of the instrument that can be close to top again is reformed, while transmitting formation fluid with dual channel.
The present invention is adopted the following technical scheme that：
A kind of oil-water well bias is reformed biography liquid device, including outer tube and eccentric pipe, and eccentric pipe is arranged in outer tube, arranges in outer tube
Shoulder in hanging, eccentric pipe upper end are arranged and hang outer shoulder, and the outer shoulder of suspension is not coaxial with main channel, set on outer shoulder being hung
Axial side stream passages are put, outer shoulder is hung and is suspended in suspension on shoulder.
Preferred embodiment, described side stream passages are axial hole or axial groove.Ring between outer tube and eccentric pipe
Following position in empty in hanging on shoulder arranges centralizer body.
Compared with prior art, the beneficial effects of the present invention is：
As a result of bimetallic tube bias suspended structure, the instrument can pass through coiled tubing, the instrument that can be close to top again
Bias reform, while transmitting formation fluid with dual channel.
Description of the drawings
The present invention is above simply described, enters one with reference next to the drawing of the specific examples below of the description present invention
Step, in detail the narration present invention.These drawings only describe some typical embodiments of the invention, therefore are not construed as limit
The scope of the present invention processed.In these drawings：
Fig. 1 is that a kind of oil-water well bias of the present invention is reformed and passes the structural representation of liquid device preferred embodiment one, the side in figure
Circulation road is axial hole, and inner tube lower end is provided with centralizer body.
Fig. 2 is that a kind of oil-water well bias of the present invention is reformed and passes the structural representation of liquid device preferred embodiment two, in figure
Side stream passages be axial groove.
Fig. 3 is A-A sectional views in Fig. 1.
Fig. 4 is B-B sectional views in Fig. 1.
Fig. 5 is C-C sectional views in Fig. 2.
Specific embodiment
As shown in Fig. 1, Fig. 3 and Fig. 4, a kind of oil-water well bias is reformed biography liquid device, including outer tube 1 and eccentric pipe 2, eccentric
Pipe arrange in the outer tube, in outer tube hang in shoulder 6, eccentric pipe upper end arranges and hangs outer shoulder 4, hang outer shoulder 4 and
Main channel 7 is not coaxial, arrange axial side stream passages 5 hanging on outer shoulder 4, and side stream passages 5 are axial hole, hang outer shoulder 4
It is suspended in suspension on shoulder 6.For the ease of the connection of this instrument and other instruments, in the bottom of eccentric pipe 2, in outer tube and partially
The interior setting in the following position for hanging on interior shoulder 6 of annular space between heart pipe installs centralizer body 3, originally in eccentric state
The righting of eccentric pipe lower end, is allowed to be changed into concentric with outer tube, and the stage casing of eccentric pipe is because hang the constraint of interior shoulder 6 and centralizer body 3
Bending can be produced.
When the instrument of the present invention is connected with lower tool, when lower tool is when being relatively large in diameter, it is also possible to help without installing
Roman, as shown in Fig. 2 using the larger external diameter of lower tool as centralizer body.
As shown in Fig. 2 and Fig. 5, side stream passages 5 can also be axial groove, and the quantity of groove can be more than 1.
Embodiment as herein described is only exemplary embodiments, but is not limited only to these embodiments, those skilled in the art
Member can make modification under the spirit without departing from the present invention and enlightenment.Aspect disclosed herein there may be many changes,
Combination and modification, and be within, therefore, protection domain is not limited only to explanation above, but according to right
Require to define, protection domain includes all equivalents of the target of claim.
