Ho na le mabaka a mangata a ho cheka ho khomaretsoeng, ka hona ho na le mefuta e mengata ea ho cheka e khomaretsoeng. Lehlabathe le tloaelehileng Le khomaretsoe, boka ba boka, ntho e oelang e khomaretsoe, casing deformation e khomaretsoe, ho tiisa samente ho khomaretsoe joalo-joalo.

2.1.Phekolo ea Lehlabathe le Khomaretseng

Haeba nako ea ho khomarela sesebelisoa e se telele kapa jeme ea lehlabathe e se e tebileng, khoele ea peipi e ka phahamisetsoa holimo le tlase ho theola lehlabathe le ho fokotsa kotsi ea jeme ea ho cheka.

Bakeng sa phekolo ea lehlabathe le tebileng le khomaretsoeng Wells, pele, mojaro o eketseha butle-butle ha mojaro o fihla boleng bo itseng, 'me mojaro o theoha hang-hang' me ka potlako o laolloa. Ntlha ea bobeli, ka mor'a nako ea mesebetsi e holimo le e tlaase, mohala oa phala o tiisoa hore o emise, e le hore mohala oa pipe o emisitsoe ka nako e itseng tlas'a boemo ba ho otlolla, e le hore tsitsipano e atolohe butle-butle ho khoele e tlaase ea pipe. Mefuta ena ka bobeli e ka sebetsa, empa mosebetsi o mong le o mong o lokela ho emisoa bakeng sa 5 ho isa ho 10min ka nako e itseng ho thibela khoele hore e se ke ea khathala le ho senya.

Lehlabathe le ts'oarellang le ka phekoloa ka mekhoa ea compression reverse circulation release, tokollo ea liphaephe, tokollo e matla ea ho phahamisa, ho lokolloa ha jack, tokollo ea reverse casing milling, joalo-joalo.

2.2.Phekolo ea ho khomarela ntho e oelang

Ho khomarela ntho e oelang ho bolela hore meno a pliers, meno a thellang, lisebelisoa tse ling tse nyenyane li oela ka selibeng ebe lia qaoa, 'me sena se fella ka ho cheka.

Ho sebetsana le lintho tse oelang ho khomarela ho cheka, u se ke ua phahamisa ka matla, e le ho thibela ho khomarela, ho baka mathata. Ho na le mekhoa e 'meli ea phekolo e akaretsang: Haeba khoele e khomaretsoeng e ka fetoloa, e ka phahamisoa ka bonolo 'me ea fetoha butle-butle. Thepa e oelang e pshatleha ho etsa hore khoele ea phala e ka tlas'a lefatše e se ke ea tingoa; Haeba mokhoa ona o ka holimo o sa sebetse, hoko ea lebota e ka sebelisoa ho lokisa bokaholimo ba tlhapi, ebe joale Refish the drop.

2.3.Tlosa mokotla o khomaretsoeng

Ka lebaka la mehato e ntseng e eketseha ea tlhahiso kapa mabaka a mang, casing e holofetse kapa e senyehile, 'me sesebelisoa sa ho theoha se theoleloa ka phoso holim'a sebaka se senyehileng, e leng se bakang ho cheka ho khomarela. Nakong ea ts'ebetso, mohala oa pipe ka holim'a ntlha e khomaretsoeng o lokela ho tlosoa 'me sekoti se ka lokolloa feela ka mor'a hore casing e lokisoe.
