Kunzwisisa DTH Drilling: Gwaro reVatangi veDown-the-Hole Technology

Munyika ine zvakawanda zvinoda kugadziriswa kwemugodhi, kuchera matombo, uye kuvaka, kushanda zvakanaka hakusi kungogumira pachinangwa—chinodiwa. Pakati penzira dzakasiyana-siyana dzinoshandiswa kupinda mumatombo akaomarara,Kuboorera pasi peHole (DTH)Inonyanya kusarudzwa senzira yepamusoro yekuputira maburi akadzika uye akatwasuka.

Asi chii chaizvo chinoitika pasi pevhu? Kana uri mutsva muindasitiri iyi, gwaro iri richatsanangura mashandiro, zvakanakira, uye zvikamu zvakakosha zvetekinoroji yeDTH.

Chii chinonzi DTH Drilling?

Pamwoyo payo,Kuboora kweDTHsisitimu yekurova. Kusiyana nekuboorera kweTop Hammer, uko simba rekurova rinogadzirwa pamusoro pevhu robva rasundirwa nepakati pematanda ekuboorera,DTH inoisa nyundo iri kumashure kwechinhu chinoboorerwa.

Sezvinoratidzwa nezita racho, nyundo inodonha "mugomba." Izvi zvinoreva kuti simba rekurova rinoiswa padombo chaipo, zvisinei nekuti gomba racho rakadzika sei.

Mashandiro Anoita Maitiro Aya: Mafambiro Matatu Akakosha

Kuboora kweDTHzvinoenderana nemusanganiswa wakabatana wezviito zvitatu zvemakanika:

1. Kurova (Kuridza ngoma):Mhepo yakamanikidzwa inodhonza pistoni mukati mehando, iyo inorova kumashure kwegomba rekuboorera kane zviuru zveminiti.

2. Kutenderera:Mota iri parig yekuboorera inotenderedza tambo yekuboorera, zvichiita kuti mabhatani ecarbide echikamu arove dombo idzva pese painorova.

3. Kudyisa (Kudzvanywa):Kudzvinyirirwa kunogara kuchidzika kunoita kuti chidimbu chirambe chakabatana nedombo, zvichiita kuti simba riwedzere kufambiswa.

Basa reMhepo:Kupfuura simba renyundo, mweya wakamanikidzwa unoshanda basa rechipiri, rinokosha:kusukira.Inofamba nepakati pemabhora, yobuda pamucheto wechinhu, yoputitsa matombo akachekwa (guruva nemachipisi) pamusoro.

Sei Uchifanira Kusarudza DTH Pane Dzimwe Nzira?

Nyanzvi dzeindasitiri dzinofarira tekinoroji yeDTH nekuda kwezvikonzero zvakati wandei zvakajeka:

• Kururama uye Kururama:Nekuti kurovera kunoitika panzvimbo yekubata, kurasikirwa kwesimba uye kutsauka kwemaburi kushoma zvikuru kana tichienzanisa nemasisitimu epamusoro-soro.

• Kugona Kuisa Hole Rakadzika:DTH ndiyo nzira yakanakisisa yekuboorera makomba akadzika (kazhinji inodarika mamita makumi maviri) nekuti simba rinorova harifanirwe kufamba nepakati petambo refu dzematanda.

• Kuchinja-chinja:Inobudirira zvikuru mukugadzira matombo ari pakati nepakati kusvika akaomarara, zvichiita kuti ive yakakosha pakuchera gomba rakavhurika uye kuchera matsime emvura.

• Kushanda Nesimba Zvakanaka:Kurova zvakananga kunoreva kusakara kushoma pamatanda ekuboorera nepamajoini, zvichikonzera kudzikira kwemari yekugadzirisa nekufamba kwenguva.

Zvikamu Zvakakosha zveDTH String

Kuti basa riitwe, gadziriro yeDTH yakajairwa inoda:

• IyoNyundo yeDTH:"Injini" yekushanda.

• IyoDTH Bit:Chishandiso chekucheka, chinowanzo shongedzwa mabhatani etungsten carbide.

• Zvimiti zvekuboorera (Machubhu):Izvi zvinopa nzira yekutenderera uye yemhepo.

• IyoCompressor:Imba yemagetsi inopa mhepo ine simba rakawanda.

Dzimwe Pfungwa dzeVatangi

Kusarudza chakakodzeraZvishandiso zveDTHZvichienderana zvakanyanya nerudzi rwedombo rako uye dhayamita yegomba rinodiwa. Kunyange zvazvo tekinoroji yacho yakasimba, kubudirira kunobva pakuenzanisa marongero emhepo yako nedhizaini chaiyo yebit.

Sezvo nzvimbo dzekuchera dzichiwedzera kuoma, tekinoroji yeDTH iri kuramba ichichinja, ichipa huwandu hunokurumidza kupinda mumabasa uye kushandiswa kwemafuta kwakangwara kunemichina yemazuva ano.
