Qhov tseem ceeb ntawm Pup Joints hauv Downhole Drilling
Pup pob qij txha rau downhole drilling, tseem hu ua spacer pob qij txha, muab ib qho tseem ceeb muaj nuj nqi. Cov ntu luv tubular no feem ntau yog 1-10 ko taw tau muab tso rau ntawm qhov sib txuas ntawm cov yeeb nkab laum. Pup pob qij txha pab kho qhov ntev tag nrho ntawm txoj hlua laum rau lub hom phiaj npaj qhov tob thiab tswj kev ntxhov siab. Lawv kuj them rau threading inaccuracies ntawm tus qauv pob qij txha. Yog tsis muaj pup pob qij txha, cov neeg ua haujlwm yuav ntsib kev txwv loj hauv kev tswj txoj hlua ntev.
Nyob rau hauv kev taw qhia drilling, pup pob qij txha pub zoo-tuning hnyav ntawm me ntsis thiab xyaum txoj hlua nro. Qhov no pab hauv kev tswj lub ntsej muag thiab qhov zoo ntawm qhov borehole. Kev npaj txhij txog drilling tej yam kev mob feem ntau xav tau kev hloov kho kom ntev - ib txoj haujlwm ua tsis tau yog tias tsis yog rau qhov yooj yim pup pob qij txha impart. Lawv siv maximizes precision thiab kev ua tau zoo ntawm drilling.
Tsim thiab Khoom siv
Pup pob qij txha rau downhole drillingNws muaj qhov ntev ntawm tsuas yog ntiv tes mus txog 10 feet ntev. Cov pob qij txha tsis tu ncua muaj tib txoj kab uas hla raws li cov yeeb nkab laum thiab phim nws cov xov sib txuas. Crossover pups hloov ntawm txawv diameters los yog xov hom. Bumper subs muaj cov kab loj loj los nruab nrab ntawm txoj hlua lossis tiv thaiv cov cuab yeej.
Lub zog nruj thiab qhov yuav tsum tau muaj qhov ntev txhais tau hais tias cov pob qij txha pob txha feem ntau yog tsim los ntawm seamless 4145H lossis zoo sib xws lub zog muaj zog laum dab tshos hlau. Thaum tshav kub kub kho lub cev muab siab torsional zog. Cov qib khoom siv feem ntau muaj qhov ua tau zoo ntawm 135 ksi mus rau 170+ ksi thiab toughness mus rau -50 degree F.
Machining tuav nruj heev OD thiab ID kam rau ua, feem ntau nyob rau hauv 0.005 ntiv tes. Floating los yog nias-haum cov cuab yeej txuas txuas ntawm kev sib txhuam welds. Cov kab me me ntawm 2 7/8" lossis 2 3/8" tuaj yeem siv cov alloys muaj zog xws li titanium lossis aluminium rau lub teeb yuag hauv kab rov tav.
Hwm threaded sib txuas tiv thaiv galling thiab xyuas kom meej torsional. Ntau kuj muaj xws li hlau-rau-hlau ntsaws ruaj ruaj los tiv thaiv kev poob siab. Qhov ntev luv ua kom nruj 100% kev soj ntsuam nrog rau cov tsis muaj kev puas tsuaj thermal, ultrasonic, thiab sib nqus particle kuaj.
Cov ntawv thov hauv Drilling Scenarios
Pup pob qij txha rau downhole drillingzoo kho qhov hnyav ntawm me ntsis los ntawm kev tswj txoj hlua buoyancy. Shortening lub laum dab tshos tsub kom WOB thaum menyuam nyob rau hauv kab rov tav seem txo luag. Hauv cov qhov dej ntsug, lawv kho qhov tob tob thiab tensile stresses. Yog hais tias drilling ntsib ib qho kev npaj txhij txog, qhov ntev ntev hloov tweak trajectories lossis loading.
Crossover pups pab kom sib xyaw cov hlua nrog sib txawv diameters thiab threads. Nyob rau hauv kab rov tav qhov dej, me me txoj kab uas hla nyob rau hauv lub lateral txo luag. Disconnecting ntawm crossover pob qij txha simplifies lub cuab tam rov qab mus rau saum npoo. Threaded adapters mates incompatible kev sib txuas ntawm bottomhole assemblies thiab laum yeeb nkab.
Bumper subs tiv thaiv MWD cov cuab yeej thiab LWD cov cuab yeej los ntawm kev poob siab. Lawv kuj tseem muab cov hlua tho hauv qhov loj dua los yog qhib qhov. Hauv kev ua haujlwm, cov menyuam yaus cov ntaub thaiv npog cov ntaub thaiv thaum hla kev txwv thaum lub sij hawm nruab thiab cementing.
Pup pob qij txha ua rau lub hom phiaj tseem ceeb los ntawm lawv qhov yooj yim rau kev ua haujlwm zoo xyaum txoj hlua ntev. Kev txhim kho cov ntaub ntawv txuas ntxiv thiab kev tsim khoom siab ntxiv yuav ntxiv dag zog rau cov peev txheej ntawm cov kev dag ntxias yooj yim tab sis ua haujlwm tseem ceeb.
