Qhov siab tshaj plaws tso cai Annular Surface Pressure ( MASP ) nyob rau hauv cov ntsiab lus yooj yim yog lub siab uas tsim yuav ua txhaum tawm ntawm hydrostatic lub taub hau ntawm cov av nkos nyob rau hauv lub casing. kev coj ua. Ua qhov Kev Xeem Leak Off yog (LOT) feem ntau yog ib qho kev coj ua thaum lub sijhawm drilling feem ntau.
Dhau li ntawm no, koj yuav ua li cas xam qhov siab tshaj plaws pub av nkos hnyav?
Qhov siab tshaj plaws pub av nkos hnyav = 13.0 ppg (los ntawm cov ntaub ntawv xau tawm) Av nkos hnyav at TVD = 12.0 ppg. Casing khau TVD = 5000 ft. Qhov tob TVD = 10,000 ft.
Ib yam li ntawd, koj yuav suav li cas tua qhov hnyav ntawm cov kua? Koj tua hnyav mud (KWM) is the mud hnyav uas yuav tso cai rau koj tswj hwm koj lub qhov dej thaum lub sijhawm ncaws pob yuav tshwm sim. Ntawm no yog qhov equation rau xam koj tua hnyav mud: KWM = Mud hnyav (ppg) + (Shut-in laum yeeb nkab siab (psi) / 0.052 / Well TVD (ft)) KWM = MW + (SIDPP / 0.052 / TVD)
Kuj paub, koj ua li cas xam qhov siab?
Siab yog ntsuas nyob rau hauv units ntawm Pascals, thiab nrhiav tus siab exerted rau a nto , tsuas yog faib cov quab yuam (hauv Newtons) los ntawm thaj chaw uas nyob rau hauv kev sib cuag nrog lub nto (hauv m2).
Yuav ua li cas koj xam qhov sib npaug av nkos hnyav?
Hloov siab mus rau qhov sib npaug av nkos hnyav
- Hloov siab hauv psi unit mus rau qhov sib npaug av nkos qhov hnyav hauv ppg los ntawm kev siv ko taw ua qhov ntsuas ntsuas. Sib npaug Mud Nyhav, ppg = siab hauv psi ÷ 0.052 ÷ True Vertical Depth (TVD) hauv ft.
- Hloov siab nyob rau hauv psi unit mus rau qhov sib npaug av nkos qhov hnyav hauv ppg los ntawm kev siv meters raws li qhov ntsuas ntsuas.

Dab tsi yog qhov ua rau muaj kev hloov pauv hauv kev tswj cov txheej txheem txheeb cais?
'Ib qho laj thawj' kev hloov pauv yog qhov kev hloov pauv uas xav tias yuav muaj nyob rau hauv cov txheej txheem ruaj khov thiab feem ntau yog vim qhov yuam kev xws li kev kaw lossis ntsuas qhov yuam kev. Cov peev txheej ntawm qhov yuam kev no yuav tshwm sim tsis hais txog lwm yam, thiab yuav ua rau muaj qhov sib txawv me ntsis ntawm kev ntsuas
Dab tsi yog qhov txawv ntawm kev tswj thiab qhov tsis tu ncua hauv kev tshawb fawb?
Qhov sib txawv ntawm qhov tsis tu ncua thiab Tswj Ib qhov hloov pauv tsis tu ncua tsis hloov. Ib qho kev tswj hwm qhov sib txawv ntawm lwm qhov kev hloov pauv, tab sis txhob txwm ua kom tas mus li thoob plaws qhov kev sim kom qhia txog kev sib raug zoo ntawm kev vam thiab kev ywj pheej
Dab tsi yog txoj hauv kev zoo li kev tshawb fawb thiab kev sib raug zoo?
Qhov zoo sib xws ntawm natural science thiab social sciences yog ob qho tib si saib cov xwm txheej tshwj xeeb. Tab sis kev soj ntsuam rau social scientist tuaj yeem muab faib ua kev soj ntsuam, nug cov lus nug, kawm cov ntaub ntawv sau. Tab sis tus kws tshawb fawb ntuj tsis tuaj yeem siv cov kev no
Dab tsi yog kev tswj zoo thiab kev tswj tsis zoo hauv gel electrophoresis?
Kev tswj qhov zoo thiab qhov tsis zoo yog cov qauv uas tau siv los lees paub qhov siv tau ntawm gel electrophoresis sim. Cov kev tswj tau zoo yog cov qauv uas muaj cov cim paub txog DNA lossis cov protein thiab yuav txav mus rau ib txoj hauv kev tshwj xeeb ntawm cov gel. Kev tswj tsis zoo yog cov qauv uas tsis muaj DNA lossis cov protein
Cov cai tswj kev tswj hwm yog dab tsi?
Kev hloov pauv hauv lub dav hlau sib koom tes feem ntau yog sawv cev los ntawm 'coordinate rules' ntawm daim ntawv (x, y) --> (x', y'). Qhov no txhais tau hais tias ib lub ntsiab lus uas nws cov kev tswj hwm yog (x, y) tau kos npe rau lwm lub ntsiab lus uas nws cov kev tswj hwm yog (x', y')
