Reverse Circulation DTH Hammer Drilling Technique

Njira yobowola nyundo ya DTH ndi gawo lofunikira kwambiri paukadaulo wobowola mpweya wa Multi-Tech, ndipo koposa zonse, ndikudutsa kwakukulu kwaukadaulo wakubowola mpweya.Zimaphatikizidwa ndi DTH yowononga thanthwe, kusuntha kwapakati pa reverse ndi kubowola mosalekeza njira zitatu zapamwamba zobowola m'dongosolo limodzi, ndipo mwachibadwa yakhala njira yophatikizira yaukadaulo wapamwamba kwambiri.Chida cholowera m'mphepete mwa DTH, chozungulira chozungulira, ndi chida chobowola pakhoma pawiri chimapangidwa ngati njira yapakati, ndiye sing'anga yothamangitsira pamodzi ndi njira yapakati kuti ipangitse kuzungulira kozungulira, kotero zimazindikirika mayendedwe oyambira pakubowola ndi kubowola. bwino anathetsa vuto la orifice fumbi kuipitsa.Pakadali pano, ukadaulo wobowolawu ukukula mwachangu limodzi ndi ntchito yomwe imakulitsidwa yomwe imakulitsidwa pang'onopang'ono, ndipo ilinso ndi ntchito zabwino pakubowola zomwe zasungidwa monga kufufuza kwapakati pa nthaka, kubowola zitsime zamadzi ndi engineering ya maziko.

Ukadaulo wofunikira pakubowola nyundo ya DTH

1. Mapangidwe apangidwe pa nyundo ya DTH

Chinsinsi cha mapangidwe apangidwe pa nyundo ya DTH ndi mapangidwe a pore.Pakatikati pa mbali zonse za nyundo pali popanga chubu.Bowo-kupyolera mu pore ndi pre-ndi-post mpweya zipinda zatsekedwa kwathunthu, ndi chubu wamkati anapanga dzenje-kupyolera pore akudutsa mbali zonse, ndi kumtunda kulumikiza ndi chubu la mkati kubowola chitoliro ndi m'munsi. pobowola kanyumba kanyumba kuti apange njira yozungulira yozungulira.Panthawi imodzimodziyo, chubu chamkati chimakhala ndi ntchito yogawa gasi.

2 Kutengera pakompyuta kwa nyundo ya DTH

Choyamba, kugwiritsa ntchito chiphunzitso choyambirira ndi masamu kupanga masamu.Kachiwiri, kutengera lingaliro lomaliza lopanga mapulogalamu apakompyuta.Pomaliza, zimatheka kutsanzira pakompyuta pamachitidwe osinthika a hammer, piston reciprocating law motion ndi magawo a ntchito ya nyundo.Ndi makompyuta omwe amathandizidwa ndi mapangidwe abwino kwambiri, magawo enieni a mayeso amapangidwa kwambiri ndi magawo otengera makompyuta.Ntchito yogwira ntchito ndi yabwino, komanso kutentha kwabwinoKuchita bwino ndipamwamba, ndipo chifukwa chake mapangidwe a nyundo amakhala asayansi.Imasintha njira zamapangidwe achikhalidwe, ifupikitsa nthawi yachitukuko, imapulumutsa mtengo wa kafukufuku ndikuwongolera magwiridwe antchito a nyundo.
