Umgaqo-siseko wokuSebenza we-Rotary Water Well Drilling Rig-1

Isixhobo sokomba samanzi ajikelezayo sixhomekeke ikakhulu kwintshukumo ejikelezayo yesixhobo sokugrumba ukuqhekeza ukumila kwamatye kunye nokwenza umngxuma. Ezona zixhaphakileyo zizixhobo zokomba ezinkulu nezincinci zembiza, phambili kunye nokubuyisela umva ukujikeleziswa kwezixhobo zokomba ezijikelezayo, iirigi zokomba zamandla oxinzelelo lwehydraulic, kunye nezixhobo zokomba ezijikelezayo eziphantsi komngxuma.

I-rotary drilling rig elula inesixhobo sokubhoboza kuphela, ngelixa i-rotary drilling rig eyenziwe kakuhle iqulethe i-drilling device kunye nesixhobo esijikelezayo sokucoca kakuhle. Isixhobo sokugaya i-rotary-table water well drilling rig ibandakanya umbhobho wokubhobhoza kunye ne-drill bit. Iidayamitha eziqingqiweyo zemibhobho esetyenziswa ngokuqhelekileyo yi-60, 73, 76, 89, 102, kunye ne-114 mm.

Iidrill zahlulahlulwe zibe ziindidi ezimbini: iidrili zokugrumba ngokuzeleyo kunye nokugrumba i-annular drilling. Iicones zembiza ezinkulu nezincinci zisebenzisa iikhowuni zeembiza zazo ukujikeleza nokusika umaleko womhlaba.

Ngokuhambelana nobukhulu bezixhobo zokugaya, zibizwa ngokuba yi-cones enkulu yeembiza kunye ne-cones encinci, enokuthi iqhutywe ngamandla omntu okanye amandla omatshini.

Isixhobo sokubhola esijikelezayo esiqhele ukusetyenziswa ekuhlambeni udaka olujikelezayo olulungileyo kunye nolungalunganga lwezixhobo zokomba ezijikelezayo, ezizezi, isixhobo sokubhola esijikelezayo esinokuhlamba udaka olujikelezayo, senziwe yinqaba, isinyusi, itafile ejikelezayo, isixhobo sokubhola, impompo yodaka, a itephu, kunye nenjini. Ngexesha lokusebenza, umatshini wamandla uqhuba i-turntable ngesixhobo sokuhambisa. Kwaye i-drill bit iqhutywa ngumbhobho wokugaya osebenzayo ukujikeleza kunye nokuphula ukubunjwa kwamatye ngesantya se-30-90 rpm.

Ukucinezela umoya wokuhlamba i-rotary rig yokugrumba isebenzisa isicinezeli somoya endaweni yempompo yodaka kwaye isebenzisa umoya ocinezelweyo endaweni yodaka ukugungxula kakuhle. Ukujikeleza okubuyela umva ngokuqhelekileyo kusetyenziswa kwaye kwaziwa ngokuba yi-gas lift reverse circulation. Umoya ocinezelweyo uthunyelwa kwigumbi lokuxutywa kwerhasi-amanzi equleni ngombhobho wonikezelo lwerhasi ukuze udityaniswe nokuhamba kwamanzi kumbhobho wokubhobhoza ukuze wenze umsinga wamanzi one-aerated kunye nobunzima obuthile obungaphantsi kwe-1.

Ngaphantsi komxhuzulane wekholomu yamanzi e-annular kwi-periphery yombhobho wokubhobhoza, ukuhamba kwamanzi ane-aerated kumbhobho wokubhobhoza kuthwala izisikwa ngokuqhubekayo kwaye ziphuma equleni, zigeleza kwi-tank ye-sedimentation, kwaye amanzi aphelile abuyela equleni. ngomxhuzulane. Xa iqula linzulu (ngaphezu kweemitha ezingama-50), ukufuduswa kwetshiphu kwesi sixhobo sokomba kukhulu kunezinye izixhobo zokomba kusetyenziswa impompo yokufunxa okanye ukujikeleziswa kwejethi umva. Esi sixhobo sokomba sifanelekile kumaqula anzulu, iindawo eziyimiqwebedu, kunye neziqwenga ezibandayo zepermafrost.

Ngolwazi oluthe vetshe, UNGAQHAGAMSHELANA NATHI ngomnxeba okanye ngeposi ekhohlo, okanye SITHUMELE MAIL ezantsi kweli phepha.
