Technical field
The invention belongs to monitoring well fiber optic protection mechanism technology fields, and in particular to one kind is used for carbon dioxide drive and envelope
Deposit the optical fiber stabilizing protector in monitoring well.
Background technique
Utilize CO2Crude oil in oil reservoir is displaced while by CO2It is stored in remaining space, is at present by CO2Emission reduction and oil
The best means that field benefit organically combines.Since oil field is the various wells formed by injection and production wells by science deployment
Net, by liquid or supercritical CO2It injects in target zone, in CO2Under the action of gas property (mobility and onlap), in plane
It is pushed ahead under the action of pressure, to the direction seepage of cap rock and diffusion on longitudinal direction, therefore in order to identify CO2It is in reservoir and complete
Well section distribution evaluates CO2It the displacement of reservoir oil and the oil displacement efficiency sealed up for safekeeping and seals safety up for safekeeping, utilizes fiber optic temperature, strain and vibration
Etc. the variation of induction of signal formation fluid to realize that purpose is a kind of good means, a kind of and completely new method.CO2The displacement of reservoir oil
Cheng Zhong, reservoir are influenced by extraneous factor, can cause temperature field disturbs and pipe Zhou Zhendong changes etc., while reservoir can occur strain and become
Change.Using Distributed Optical Fiber Sensing Techniques, sensing optical fiber laying is installed to outside of sleeve, can temperature to oil bearing bed it is different
Often and abnormal vibration detects and strain deformation monitoring, in order to obtain CO2The displacement of reservoir oil and borehole strain, temperature and vibration during sealing up for safekeeping
Emotionally condition is laid strain, temperature and vibrating sensing optical fiber and is monitored, optical fiber is attached to outside of sleeve and is transferred to drilling,
Then by the outer slip casting well cementation of casing, optical fiber and drilling surrounding formation and casing are achieved the purpose that into coupling.
However, optical fiber decentralization and installation process in there are many security risks, the pit shaft borehole wall is not smooth, optical fiber
Sleeve outer wall is mounted on to be easy to friction, collide in the borehole wall and due to as the bigger casing self weight of casing setting depth increases therewith
Add, optical fiber is also increasing by downward pulling force and leads to install failure, and currently used for straight well, inclined shaft or horizontal well
Centralizer functions only as centralizing function, can not play a protective role to optical fiber, so that the optical fiber installation inside monitoring well is more tired
It is difficult.
Summary of the invention
It is a kind of for titanium dioxide technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art, providing

Inside offers multiple fiber optic protection slots, can complete under the action of fiber optic protection slot when so that optical fiber being installed in monitoring well
Centralizing function, while can also protect to optical fiber uses convenient for the installation of optical fiber in monitoring well with connecting.
2, the present invention is by being fixedly installed multiple lantern columns on the outside of upper positive round card and lower positive round card, and lantern column is by water
Flat indent radian is made of 45 degree, vertical curve degree of 2 degree and width of 3 centimetres of elastic iron sheet, so that centralizer uses
It is independently buffered by after external forces in the process, enhances the protective effect to optical fiber.
3, the present invention is by being provided with multiple idler wheels in the side of lantern column, so that centralizer during the installation process can
The frictional force with monitoring well side wall is reduced by idler wheel, is easily installed going on smoothly for process.
4, upper positive round card is connected composition centralizer by the way that multiple lantern columns are arranged by the present invention with lower positive round card, so that righting
Device is avoided that in use occurs the risk that upper and lower displacement makes optical fiber itself bear pulling force, convenient for normally making for optical fiber
With, while being made between optical fiber stabilizing protector and casing tightly by multiple lateral jackscrews that upper positive round card and lower positive round are arranged with
Closely connected conjunction avoids that axial rotation occurs, and guarantees that optical fiber is not influenced by shearing force.
5, the present invention makes conventional centralizer and protector for optical fiber become a system entirety, in the actual construction process largely
The saving operating time, reduce construction risk.
