Description
Technical field
Present document relates to but be not limited to stowage unit field, espespecially one kind exempt from bore exempt to fish out solid completion integral tubing string.
Background technique
Under normal conditions, offshore oilfield well cementing operation and completion practice adhere to two different construction technologies separately, and construction exists
The problems such as construction time is long, casing program is complicated.Land, which is being applied, at present exempts to bore solid completion integral technique and is applied with shortening
Between working hour, casing program is reduced.
Land application at present exempts from that bore solid completion integral process flow as follows:
One, pipe string structure forms: guide shoe+screen casing+exempts from drill tools+casing.
Two, pipe string in place after, well head is suppressed, and envelope swollen first exempts from the external packer of pipe on drill tools, insulates annular space, continues to beat
Pressure, opening exempt from drill tools stage cementing device, establish circulation, normal procedure well cementation, and the later period throws rubber plug bruising, and well cementation terminates.
Three, after Hou Ning, drill tools internal structure, and milling drifting are exempted from the lower macaroni with fishing tool, salvaging, whole
A complete well construction terminates.
But there are biggish hidden danger and deficiency for current solid completion integral technique of exempting to bore:
Casing cementing and rubber plug is needed to replace cement 1. exempting from drill tools, it is endless there may be replacing that rubber plug replaces cement
Entirely, the case where internal surface of sleeve pipe residual cement；
2. the technique closes cementing device circulation port using hydraulic open cementing device circulation port, rubber plug bruising, actually apply
It is easy to appear circulation port in work and opens the case where fitting badly, influences cementing quality；
3. after well cementation, needing lower fishing tool salvaging to exempt from drill tools internal structure, salvaging back and take difficulty.
Summary of the invention
At least one of in order to solve the above-mentioned technical problem, exempt to bore there is provided herein one kind and exempts to fish out solid completion integral pipe

So that cement is passed through the circulation port of mechanical ON/OFF formula cementing device 6, be injected into inside casing tubing string and open hole well, rubber plug 15 with touch
Bruising is realized in the contact of wedge 7.
Five, it slips out of the hand setting tool string tubing string, Hou Ning completes integrated solid well operations.As shown in Figure 5
After bruising, rotation setting tool string tubing string is above mentioned and be buckled to, is closed by anchor mechanism (driving in-migration on inner cylinder)
The circulation port of mechanical ON/OFF formula cementing device 6 is closed, casing tubing string is completed and slips out of the hand with setting tool string tubing string, take out setting tool
String tubing string, Hou Ning complete integrated solid well operations.
Wherein, structure includes: stratum 1, outer layer sleeve 2, outer layer cement 3 and oil pipe 16 in well.
In conclusion brill provided by the invention of exempting from exempts to fish out solid completion integral tubing string, circulation bore closure has been well solved
It is not tight, return the problem for taking rubber plug difficulty etc..Setting tool string tubing string is installed in place recoil sealing tube external packer, pushes setting tool
Tubing string of going here and there opens ON/OFF formula cementing device, and cementing and bottom plug replace in drilling rod, above mention the closing of setting tool string tubing string open/
Pass formula cementing device, which returns, takes rubber plug, and entire construction process is coherent, avoids the Hou Ning waiting time.
