Iimbangela kunye nezisombululo zokuncamathela

Ukuncamathela, okwakwaziwa ngokuba kukuncamathela koxinzelelo oluhlukileyo, yeyona ngozi ixhaphakileyo yokuncamathela kwinkqubo yokomba, ibalelwa ngaphezulu kwe-60% yokusilela kokuncamathela.

Izizathu zokuncamathela:

(1)Intambo yokomba inexesha elide elingashukumiyo equleni;

(2) Umahluko woxinzelelo equleni mkhulu;

(3) Ukusebenza kakubi kolwelo lokomba kunye nomgangatho ophantsi wekeyiki yodaka kubangela ukukhuhlana okukhulu;

(4) Umgangatho ophantsi wamaqula.

Iimpawu zokuncamathelisa i-drill:

(1) Ukuncamathela kukwimo emileyo yomtya wokugrumba kunokwenzeka, njengoko ixesha elingatshintshiyo liya kwenzeka lixinge, linxulumene ngokusondeleyo nenkqubo yolwelo lokomba, ukusebenza, ubume bokomba, umgangatho womngxuma, kodwa kufuneka kubekho inkqubo emileyo.

(2)Emva kokuncamathelisa i-drill, indawo yokuncamathela ayiyi kuba yi-drill bit, kodwa ikhola ye-drill okanye i-drill pipe.

(3) Ngaphambi nangemva kokunamathela, ukujikeleza kwamanzi okugaya kuqhelekile, ukungenisa kunye nokuthumela ngaphandle kokuhamba kulungelelaniswa, kwaye uxinzelelo lwempompo alutshintshi.

Uthintelo lokuncamathela:

Iimfuno ngokubanzi, ixesha lokubhola lokubhola alifanele lidlule kwimizuzu emi-3. Umgama we-drill nganye awukho ngaphantsi kwe-2m, kwaye ukujikeleza akukho ngaphantsi kwemijikelezo ye-10. Emva komsebenzi kufuneka ubuyiselwe kubunzima bokuqala bokunqunyanyiswa.

Ukuba i-drill bit isezantsi komngxuma kwaye ayikwazi ukuhamba kwaye ijikeleze, kuyimfuneko ukucinezela i-1 / 2-2 / 3 yobunzima obunqunyanyisiweyo besixhobo sokubhoboza kwi-drill bits ukuze ugobe umtya wokubhola ophantsi, ukunciphisa indawo yoqhagamshelwano phakathi komtya we-drill kunye nekhekhe lodaka eludongeni, kwaye unciphise ukunamathela ngokupheleleyo.

Ngethuba lokugaya okuqhelekileyo, okufana nokungaphumeleli kwe-faucet okanye i-hose, umbhobho we-kelly akufanele uhlaliswe kwi-wellhead ukwenzela ukulungiswa. Ukuba ukugrumba okuxingileyo kwenzeka, kuya kuphulukana nokuba nokwenzeka kokucinezela kunye nokujikelezisa umtya wokubhola.

Unyango lokuncamathela:

(1) Umsebenzi owomeleleyo

Ukuncamathela kuba ngakumbi nangakumbi ngokwandiswa kwexesha. Ngoko ke, kwisigaba sokuqala sokufumanisa intonga, amandla aphezulu kufuneka aqhutywe ngaphakathi komthwalo okhuselekileyo wezixhobo (ngokukodwa i-derrick kunye nenkqubo yokumiswa) kunye nentambo ye-drill. Ayigqithisi umda womthwalo okhuselekileyo wekhonkco elibuthathaka, kwaye ubunzima bomtya we-drill wonke unokucinezelwa kuxinzelelo oluphantsi, kwaye ukujikeleza okufanelekileyo kunokwenziwa, kodwa akunakudlula inani eliqingqiweyo lokujika kwe-torsion. umbhobho wobhobhoza.

(2)Vula ikhadi

Ukuba intambo yokubhoboza inengqayi ngelixa kusemba, kufuneka iqalise kwangoko isando sangaphezulu phezulu okanye iqalise isando esisezantsi ukusombulula ikhadi, eligxininiswe ngakumbi kunokonyuka nokuhla kwamandla.

(3) Gxilisa i-arhente yokukhulula

Iarhente yokukhupha ukuntywiliselwa yeyona ndlela isetyenziswa ngokuqhelekileyo kwaye ibalulekileyo yokukhulula i-drill ebambekayo. Kukho iintlobo ezininzi ze-jam release agents, xa sithetha ngokubanzi, kubandakanywa ioli ekrwada, ioli yedizili, iikhompawundi zeoli, i-hydrochloric acid, i-asidi yomhlaba, amanzi, amanzi etyuwa, amanzi e-alkali, njl. zezinto ezikhethekileyo zokuphakamisa i-drill yokubambelela, kukho i-oyile-based, kukho isiseko samanzi, ubuninzi babo bunokutshintshwa njengoko kufuneka. Indlela yokukhetha i-arhente yokukhulula, kuxhomekeke kwimeko ethile yommandla ngamnye, uxinzelelo oluphantsi kakuhle lunokukhethwa ngokuthanda, uxinzelelo oluphezulu lunokukhetha kuphela i-agent yokukhululwa kwe-high-density.
