I-App Terrain kanye Nezimpawu ze-Reamer

I-reamer ifaneleka kakhulu ukwakheka okuthambekele ekuthambekeni nasekuncishisweni kobubanzi, ikakhulukazi ekwakhekeni kokumba okuthambekele ekuthambekeni nasekuncishisweni kobubanzi, okubonisa inani layo eliyingqayizivele lesicelo. .

Izinsimbi zokumba uwoyela, ezaziwa nangokuthi izinwebe noma ama-reamer, zidlala indima ebalulekile kubunjiniyela bokumba uwoyela. Umsebenzi wabo oyinhloko uwukwandisa i-borehole ngesikhathi sokumba. Ngokuwafaka phakathi nentambo yokubhoboza enobubanzi obungaphezudlwana kobubanzi be-drill bit, aqinisekisa ukuthi i-reamer engaphezulu ngesikhathi esisodwa ikhulisa imbobo futhi ilungisa umthombo ngesikhathi sokumba. Ukwakhiwa kwaleli thuluzi kucabangela izimo ezihlukahlukene eziyinkimbinkimbi ezingase zihlangabezane nazo ngesikhathi sokumba, njengezinguquko ekubunjweni kwe-lithology, izinga lokushisa kanye nokushintshashintsha kwengcindezi, ngakho-ke kunezici ezithile zobuchwepheshe kanye nezinzuzo:

Isimo sezwe esisebenzayo: I-remer ifaneleka ngokukhethekile ukwakheka okuthambekele ekuthambekeni nasekunciphiseni ububanzi. Ngenxa yesakhiwo se-geological esiyinkimbinkimbi, lokhu kwakheka kujwayele ukuthambekela kwe-wellbore noma izinguquko zobubanzi ngesikhathi sokumba. Ngokusebenzisa isinwezi samehlo, ukuthambekela komthombo kungalawuleka ngempumelelo ngenkathi kuqinisekiswa ukuhambisana kobubanzi bomthombo, ngaleyo ndlela kuthuthukiswe ukuphepha nokusebenza kahle kokumba.

Izici zobuchwepheshe:

I-Hydraulic reamer: Isibonelo, ukusetshenziswa kwe-Shengli hydraulic reamer emithonjeni ejulile kakhulu kubhekane ngempumelelo nobunzima bokwakha obufana nezinga lokushisa eliphezulu, umfutho ophakeme, kanye nokushintshanisa amatshe athambile futhi aqinile ngokuthatha izinyathelo ezinjengokucindezela okuphansi kokumba, ukufuduka okuncane, nokukhetha. izingxenye zokuvala izinga lokushisa eliphezulu ezimelana nezinga lokushisa eliphezulu, eziqinisekisa ukuqhubeka kahle kokwakhiwa kwe-eye expander.

Uhlobo olusha lwe-reamer: Ngokuthuthukiswa kwemboni ye-petroleum, ucwaningo nokuthuthukiswa kohlobo olusha lwesinwebi samehlo seludingeka ukuze ubhekane nezimo eziyinkimbinkimbi emithonjeni ejulile kanye ne-ultra deep, njengemilenze yenja, imigwaqo engukhiye, nama-diameter ancishisiwe. Lezi zinhlobo ezintsha zezandisi zamehlo zinokuqina okuphezulu nokuthembeka, futhi zingahlangabezana nezidingo zokumba umthombo ojulile.

I-Reamer Drilling: njenge-Halliburton's TDReam™. I-reamer yokumba inciphisa ubude be-borehole ibe ngaphansi kwamafidi angu-3, ​​yonga isikhathi sokumba nezindleko, futhi yehlise nezingozi. Ukuklanywa kwaleli thuluzi kuvumela ukunwetshwa okuqondile kwe-borehole ngesikhathi sokumba ngaphandle kwesidingo sezinyathelo ezengeziwe zokukhubeka, ngaleyo ndlela kuthuthukisa ukusebenza kahle komsebenzi.
