Kusimuka kweHDD: Kukunda Zvinetso muHard Rock Projects.

Mumakore achangopfuura, kudiwa kwe horizontal directional drilling (HDD) yakawedzera zvinoshamisa. Izvi zvinotarisirwa kuenderera mberi mumakore gumi ari kutevera. Inotungamirirwa nekuwedzera kutaurirana uye simba rinodiwa,HDDmakondirakiti achasangana nematambudziko ari kukura pakuisa tambo dzepasi pevhu nemapaipi.

TraditionalHDD zvishandiso inogona kushandiswa kumapurojekiti akasiyana. Nekudaro, zvigadzirwa izvi hazvisi izvo zvinonyanya kushanda pakuchera mumatombo ane matombo. Kana makondirakiti asangana nematambudziko, maturusi asina kukodzera anogona kuderedza kufambira mberi uye kuwedzera mitengo. Kuti ubudirire kupedzisa mapurojekiti mumatombo akaomarara, zvinhu zvitanhatu zvakakosha zvinofanirwa kutariswa.

1. ShandisaPneumatic Down-the-Hole Sando

Mazhinji anotungamira HDD makondirakiti atora pneumatic pasi-iyo-gomba sando dzekuchera mumatombo. Zvichienzaniswa neyakajairwa nzira yekuchera maturusi anoshandiswa mune akapfava mafomati, pasi-iyo-gomba sando dzinopa zvakakosha zvakakosha. Chinonyanya kukosha, maturusi epasi-gomba anogona kudhiza kuburikidza nemhando dzakasiyana-siyana, kusanganisira dombo rakaoma, dombo rakaputsika, matombo, matombo, uye loose geology. Pamberi peaya mamiriro e geological, pasi-the-gomba maturusi ane yakanyanya budiriro mwero wekupinda. Muchidimbu, maturusi epasi-pagomba anoshanda zvakanyanya pakuchera nepadombo, zvichigona kuganhura nguva yekuchera nehafu kana kupfuura.

2. Gadzirira Maturusi Ese Panzvimbo Yebasa

Geological mamiriro uye magadzirirwo epurojekiti anogona kuchinja chero nguva, saka zvakakosha kuve nemidziyo yemidziyo yakagadzirira kusangana nezvinodiwa zvekuvaka zvakasiyana. Sezvambotaurwa, maumbirwo akasiyana ekuchera anoda maturusi akasiyana. Pakuumbwa kwevhu, zvechinyakare, zvakajairika mabhiti kana maturusi anodiwa, nepo rock geology inoda pasi-paburi sando. Vashandi vanofanirawo kushandisa diverter kubatanidza reamer nepombi panguva yekudzokororwa, zvichibvumira remer kutenderera ichichengeta pombi yakamira, ichingoiswa simba rekudhonza kwete torque, kudzivirira kumonyoroka nekukuvadza pombi. Pamusoro pezvo, ma hydraulic anokurumidza-kuburitsa ma clamps anokurudzirwa kuchengetedza. Chekupedzisira, zvimwe zvinodyiwa zvinofanirwa kugadzirwa, senge zvibooreso, zvitsigiso, zviboorero, uye mabhii ekutungamira. Vashandi vanofanirwa kugadzirira pachine nguva kudzivirira mhirizhonga panzvimbo yebasa.

3. Gara Uchengetedza Zvishandiso Kuti Uwedzere Hupenyu

Kugadziriswa kwakakodzera kwemidziyo kwakatwasuka asi kazhinji kunofuratirwa nevazhinji makondirakiti. Vanogara vachiisa maturusi kure zvakananga mushure mekushandisa, chete kuti vaabudise kunze kwepurojekiti inotevera. Muchokwadi, zvese zvishandiso zvinofanirwa kucheneswa nekukurumidza mushure meprojekiti yega yega. Vashandi vanofanirwa kuona kuti diverter yaiswa mafuta mushure mekunge chirongwa chapera; kune pneumatic down-the-hole sando, zvakakosha kubvisa mweya mushure mekushandisa, kuchengeta sando yakachinjika, uye kuichengeta munzvimbo yakaoma. Nokuda kwekuchengetedza kwenguva refu, sando inofanira kuparadzaniswa, uye zvinhu zvose zvinoongororwa kuti zvive nechokwadi chekushanda kwakakodzera uye kuti mukati memudziyo hauna kusvibiswa.

4. Zvinhu Zvokufunga nezvazvo Pakusarudza Hard Rock Tools

Pane kuchinja kukuru kwekuita pakati pezvishandiso, uye sekureva kunoita chirevo, "unowana chaunobhadharira." Zvese zvikamu zvekuchera, kubva kune rig kusvika kune drill bit, zvinofanirwa kuenderana. Makondirakiti anofanirwa kunyatsosarudza maturusi ekudzivirira zvigadzirwa zvepasi zvinokanganisa kunaka kweprojekiti. Paunenge uchisarudza hard rock zvishandiso, funga zvinotevera pfungwa:

• Kuita kweiyo rig kunofanirwa kuenderana nemamiriro e geological.
• Ongorora mutengo wezvishandiso uye mutengo wakakwana wekuvaka.
• Sarudza kana maturusi chaiwo nemidziyo zvinodiwa.
• Isa pamberi maturusi ane anotungamira maficha, yakakwira mareti ekupinda, kugadzirisa kuri nyore, uye mutengo wakaderera wekuvaka.
• Sarudza vagadziri vezvishandiso vane mbiri.
• Chengetedza kubatana kwepedyo nezvikwata zvenyanzvi dzeprojekiti.

 5. Common Issues muna Hard Rock Directional Drilling Projects

Kuita ongororo yakakwana uye kuronga kweprojekiti usati watanga kunogona kuderedza zvakanyanya kukanganisa kwakajairika. Injiniya yeprojekiti inokwanisa anofanira kuita zvinotevera:

• Nyatsonzwisisa mamiriro ejoloji uye gadzira zvirongwa zvekuvaka zvinoenderana purojekiti isati yatanga.
• Nyatsosarudza maturusi anonyatsoenderana nezvinodiwa zvekuvaka.
• Ita shuwa kuti chibhorani chakapetwa ka1.5 pane chepombi, kudzivirira masaizi akakurisa kana kuti madiki.
• Tsvaka mazano enyanzvi nekukasika kana pamuka matambudziko.

6. Chengeta Zvishandiso Zvakachena

Semuyenzaniso, pneumatic down-the-hole sando dzinoshandisa mweya wakadzvanywa sesimba, nemapistoni anodzokerana mukati memasilinda kuti adzokorore kukanganisa kumashure kwechibooreso, kuita basa rinoenderera uye kugadzira simba repamusoro-frequency padombo rinoda kutyorwa. Panguva imwecheteyo, gasi rinotonhodza chibooreso uye rinobvisa kucheka pasi pemamwe mamiriro ekuyerera kwemhepo kuzadzisa zvinangwa zvekuchera. Ita shuwa kuti maturusi akachena asati ashandiswa kudzivirira jamming panguva yekuvaka. Nekukura kuri kukura kwepasi pevhu fiber optics, kutaurirana, uye mamwe mapurojekiti emanisipala, zvikwata zvine ruzivo rwehunyanzvi hwekuita uye ruzivo rwakapfuma rwekuchera zvichave vatungamiriri mukugadzira indasitiri.
