Qhov zoo thiab qhov tsis zoo ntawm kev cuam tshuam rov qab ncig drilling rig thiab teb drilling rig hauv kev tsim kho
Raws li cov kev tsim kho, cov strata sib txawv thiab cov cheeb tsam sib txawv tab sis tib qhov drilling txoj kab uas hla yog muab piv, nws pom tau hais tias qhov cuam tshuam rov qab thiab cov rotary zoo ncig muaj lawv tus kheej zoo, feem ntau nyob rau hauv cov av nplaum, loam, silty av txheej, silt txheej. Thaum lub sij hawm tsim kho, los ntawm kev qhia txog cov ntaub ntawv drilling hauv cov pab pawg me thiab siv cov ntaub ntawv nruab nrab ntawm txhua tus txheej txheem, cov rotary drilling rig yog 1.2 npaug sai dua qhov cuam tshuam rov qab ncig drilling rig. Qhov nruab nrab kev tsim kho tsis yog nrawm li qhov zoo ntawm cov pob zeb drilling rig, tab sis nyob rau hauv pebble gravel txheej thiab bedrock kev tsim kho, qhov cuam tshuam rov qab ncig drilling yog pom tseeb 3 zaug sai dua li cov rotary drilling rig, feem ntau ntau dua 2 zaug sai dua rau pob zeb hauv qab no. 5cm, thiab sai dua rau 5-10cm gravel Ntau tshaj 3 zaug, thiab qhov cuam tshuam rov qab ncig drilling rau hauv pob zeb hauv qab qib 5, qhov drilling ceev yog 5 mus rau 6 npaug sai dua li qhov drilling rotary. Lub qhov ua kom nrawm ntawm cov dhuav pawg muaj qhov zoo tshaj plaws, tshwj xeeb tshaj yog nyob rau qee qhov chaw toj siab thiab roob, thiab qhov zoo yog qhov tseem ceeb dua. Piv txwv li, ntu Xiapu ntawm Fujian Funing Expressway yog ib qho piv txwv zoo, lub sij hawm rau tag nrho pawg yuav tsim yog ntau tshaj 3 zaug sai dua li ntawm cov teb drilling rig.
Rau kev tsim ntawm lub qhov, lub qhov taub ntawm qhov cuam tshuam rov qab kev tsim kho feem ntau yog siv rau hauv kev tsim cov av nplaum, loam, silty av thiab silt khaubncaws sab nraud povtseg los tiv thaiv lub qhov los ntawm collapsing. Degree zoo dua. Hauv kev tsim cov qe thiab gravel txheej, cuam tshuam rov qab ncig drilling yog siv. Vim muaj kev cuam tshuam loj heev, nws yog ib qho yooj yim rau kev tawg lub qhov thiab lub filling coefficient loj heev. Cov coefficient yog 1.15; Thaum lub filling coefficient ntawm lub percussion rov qab ncig drilling seem yog 1.25, thiab cov filling coefficients nyob rau hauv cov av txheej yog nyob ze rau 1.1.
Nyob rau hauv cov nqe lus ntawm tus nqi noj: nyob rau hauv kev tsim kho ntawm av nplaum, loam, silty av txheej thiab silt khaubncaws sab nraud povtseg, tus nqi noj ntawm cov kev cuam tshuam rov qab ncig yog loj dua li cov rotary drilling rigs. Lub ntsiab cuam tshuam drilling rigs muaj lub zog siab thiab kev siv hluav taws xob. Tsis tas li ntawd, kev siv cov hlua hlau steel yog qhov loj, vim qhov cuam tshuam ntawm txoj hlua siv, qhov hnyav hnyav, thiab cov nqi thauj mus los siab. Txawm li cas los xij, hauv kev tsim cov qe, gravel txheej, pob zeb, pob zeb, thiab cov pob zeb, qhov cuam tshuam drilling efficiency siab, thaum lub teb drilling rig grinds cov ntaub ntawv. Kev noj yog loj, qhov drilling ceev yog qeeb, lub voj voog ntawm lub qhov ntev ntev, thiab tus nqi yog ntau tshaj 5 npaug ntawm qhov cuam tshuam qhov drilling. Nyob rau hauv cov ntaub ntawv ntawm pob zeb loj, pob zeb loj, thiab granite rotary drilling rigs nrog siab hardness, nws yog tsis yooj yim sua rau xyaum, thiab tsuas yog siv cov kev cuam tshuam rov qab. Rig kom tiav.
Hais txog kev cuam tshuam ib puag ncig, qhov cuam tshuam ntawm kev rov qab ncig drilling kev vibration ntawm ib puag ncig ib puag ncig yog ntau dua li ntawm cov teb drilling, tshwj xeeb tshaj yog thaum cuam tshuam rau lub hauv paus nyuaj pob zeb nto, qhov cuam tshuam kev co ua suab nrov nrov thiab cuam tshuam rau tib neeg so.
Hauv luv luv, kev xaiv cov cuab yeej tseem ceeb heev thaum tsim lub hauv paus, thiab cov txheej txheem kev tsim kho sib txawv yog siv rau cov strata sib txawv. Nyob rau hauv kev tsim kho ntawm cov xuab zeb txheej, rotary drilling yog saws, uas muaj qhov zoo ntawm tus nqi qis, zoo tsim qhov zoo, lub teeb yuag ntawm pawg tsav tsheb, thiab yooj yim txav chaw. Nyob rau hauv cov nqe lus ntawm kev kho mob, kev siv percussion rov qab ncig drilling yog tsim nyog, vim hais tias nws muaj peev xwm ua kom lub sij hawm tsim kho, txhim kho drilling efficiency, thiab xyuas kom meej qhov zoo ntawm qhov project. Yog li ntawd, thaum tsim cov dhuav pawg, peb yuav tsum siv cov kev tshawb fawb los xaiv cov cuab yeej thiab cov txheej txheem raws li qhov chaw, kev tsim kho lub sij hawm, geological tej yam kev mob thiab tus nqi tsom xam, thiab siv cov cuab yeej siv zoo tshaj plaws los xyuas kom zoo, lub sij hawm tsim kho, thiab tus nqi. Tsim cov txiaj ntsig zoo tshaj plaws thaum muaj kev nyab xeeb.
