Iimbangela kunye nezisombululo zokuncamathela

Ukuncamathela, okwakwaziwa ngokuba kukuncamathela koxinzelelo olwahlukileyo, yeyona ngozi ixhaphakileyo yokuncamathela kwinkqubo yokomba, ibalelwa ngaphezulu kwe-60% yokungaphumeleli 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 wokubhola 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.

Ngexesha 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 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.Ayidluli 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 ye umbhobho wokubhola.

(2)Vula ikhadi

Ukuba umtya wokubhobhoza unengqayi ngelixa ugrumba, kufuneka uqalise kwangoko isando sangaphezulu phezulu okanye uqalise isando esisezantsi ukusombulula ikhadi, eligxininiswe ngakumbi kunokonyuka nokuhla kwamandla.

(3) Gxilisa i-arhente yokukhulula

I-arhente yokukhulula 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 yokukhululwa, kuxhomekeke kwimeko ethile yommandla ngamnye, uxinzelelo oluphantsi lunokukhethwa ngokuthanda, uxinzelelo oluphezulu lunokukhetha kuphela i-agent yokukhululwa kwe-high-density.
