Pup pob qij txhayog cov ntu luv ntawm cov yeeb nkab siv hauv ntau yam kev siv downhole thaum lub sij hawm drilling, ua tiav, thiab kev ua haujlwm ntau lawm. Raws li qhov chaw uas lawv tau xa mus, lawv tau muab faib ua casing, laum yeeb nkab, ib qho, lossis cov pob qij txha. Txhua hom ua haujlwm tshwj xeeb.
1. Tubing Pup Joints
Cov hlau luv luv no yog siv rau hauv cov tubing cov hlua ntawm cov tubing li niaj zaus. Qhov ntev ntev yog 2 ft rau 10 ft.
- Ua kom raug tsaws ntawm cov khoom ntim khoom.
- Kho cov hlua hlua ntev raws li kev ntsuas kev ntsuas siab.
- Pom cov gels lossis tshuaj thaum muaj kev cuam tshuam zoo.
- cais thaj chaw rau xaiv perforation.
- Ua kom yooj yim rau kev ua haujlwm ua haujlwm los ntawm kev muab qhov chaw tawm yooj yim.
- Rub lossis khiav ua tiav cov khoom sib dhos zoo li subsurface li qub.
2. Casing Pup Joints
Nws yog cov kav hlau luv luv tso rau hauv nruab nrab ntawm cov hlua khi li niaj zaus. Ntev ntev li ntawm 2 ft mus rau 10 ft.
Nws muaj threaded kev sib txuas sib xws nrog cov hlua casing specifications. Lawv yog cov cuab yeej siv hauv:
- Ua kom tiav qhov kev tsaws ntawm cov khau khau ntawm lub hom phiaj qhov tob.
- Kho cov hlua tag nrho ntev kom haum rau qhov sib txawv ntawm qhov tob.
- Txhim kho cov plugs ib ntus thaum tso tseg zoo.
- Circulating hauv qab mus tom qab casing cementing.
- Tshem tawm cov khib nyiab pov tseg ntawm lub rooj zaum khau.
- Muab kev hloov pauv hauv kev khiav cov hlua ntev ntev.
- Ua kom yooj yim ntawm cov kab hauv kab.
Kev siv kom zoo yuav txuag lub sijhawm tseem ceeb ntawm cov rig thiab txo cov kev pheej hmoo ua haujlwm thaum lub sijhawm tsim kho qhov dej tseem ceeb.
3. Drill Pipe Pup Joints
Cov no yog cov kav hlau luv luv uas siv rau hauv txoj hlua laum ntawm cov yeeb nkab sib txuas. Ntev ntev li ntawm 2 ft mus rau 10 ft.
Daim ntawv thov:
- Txhim kho BHA cov cuab yeej zoo xws li stabilizers, MWD cov cuab yeej, LWD sensors, av nkos motors, thiab lwm yam.
- Circulating bottoms mus ntxuav qhov tom qab drilling los yog cementing hauj lwm.
- Khiav kev ntsuas siab thoob plaws kev tsim siv kev sib koom ua ke kom cais cov cheeb tsam.
- Tso cov kev ncig thaum lub sij hawm cov yeeb nkab daig thiab sim pom cov kua dej hla lub sijhawm luv.
- Dawb daig laum hlua los ntawm kev rov ua dua rov qab jarring nrog cov menyuam yaus ntsia.
- Pab kom txiav thiab khaws cov ntses thaum nuv ntses rau cov hlua khi hlua khi.
4. Integral Pup Joints
Cov menyuam dev no muaj cov cuab yeej sib koom ua ke ntawm ob qhov kawg thiab yog siv los ua qhov sib koom ua ke ntawm cov yeeb nkab sib txuas. Integral pups muab kev ua haujlwm yooj yim zoo ib yam li cov qauv tho yeeb nkab.
Cov ntawv thov tseem ceeb yog:
- Kho qhov laum txoj hlua ntev rau qhov tseeb BHA qhov chaw.
- Kev sib txuas ntawm qhov sib txawv ntawm cov tho yeeb nkab sib txuas ntawm qhov sib txawv ntawm qhov ntev.
- Pab nuv ntses thiab jarring dej num.
- Ua kom yooj yim laum txoj hlua sib dhos thiab tuav ntawm qhov chaw rig.
Kev xaiv kom raug thiab siv cov casing, laum yeeb nkab, ib qho, lossis tubingpup sibtxhim kho kev ua haujlwm tau zoo thaum lub sij hawm tsim kho, ua tiav, thiab kev pabcuam, uas txuas ntxiv muab txoj hauv kev pheej yig los ua kom zoo dua tubular hlua ntev rau cov kev xav tau tshwj xeeb hauv downhole.
