I-Hole Opener

1.Ukwethulwa kwamathuluzi

Isivuli sembobo siyi-micro eccentric reamer, engaxhunywa kuntambo yokubhoboza ukuze kuzuzwe ukubuyiswa kabusha okuncane ngenkathi umba. Ithuluzi linamaqembu amabili ama-spiral reamer blades. Iqembu le-blade engezansi linomthwalo wemfanelo wokubuyisela emuva ngenkathi kubhoboza noma ukuphinda kufakwe kabusha ngesikhathi sokumba, futhi iqembu le-blade ephezulu libhekene nokuhlehla kabusha ngesikhathi sokumba. Umsebenzi oyinhloko wethuluzi ukunciphisa ubunzima be-dogleg emthonjeni oqondisayo, ukususa i-downhole micro-doglegs kanye nezinyathelo ezincane, futhi wandise i-borehole ngobubanzi obungaphezudlwana kobubanzi bethiyori be-drill bit ku-shale enwetshiwe. ukwakheka kanye nongqimba olunwabuzelayo lukasawoti-gypsum, ungqimba oluthambile lwetshe lodaka, umthungo wamalahle nezinye izingxenye zomthombo, ezinganciphisa isikhathi sokusebenza kabusha enqubweni evamile yokumba futhi kuqinisekise ukusebenza okuphephile nokushelelayo kokukhubeka, ukugawulwa kwemithi kagesi, ukugijima kwe-casing kanye nokunwetshwa kwepaki. . Ngaphezu kwalokho, leli thuluzi libuye libe nomsebenzi wokukhipha umbhede wokusika emithonjeni eqondisayo kanye nokulawula ngempumelelo i-ECD yemithombo evundlile kanye nemithombo yokufinyelela enwetshiwe.

2. Ububanzi besicelo

· Imithombo ye-Shale

· ukufinyelela enwetshiwe kahle

· Ungqimba lukasawoti-gypsum, ungqimba lwetshe lodaka elithambile, umthungo wamalahle nokunye okukhasa phansi

· I-hydration enwetshiwe

· Serious cuttings embhedeni kahle

3. Izici zesakhiwo

· Ingxenye eyodwa, azikho izingxenye ezihambayo, amandla aphezulu kunamandla wepayipi lokubhoboza elixhunywe nalo

· Ixhunywe kukholomu yepayipi lokubhoboza, akuthinti ukubekwa kwekholomu kanye nokusebenza kweplathifomu enezendlalelo ezimbili kuma-derricks amaningi

· I-Hydraulic, umonakalo wesenzo esiphindwe kabili, susa umbhede wokusika

· Izici eziphakathi nendawo zinganweba usayizi wemigodi ube mkhulu kunethuluzi ngobubanzi

· I-spiral blade isiza ukuthuthukisa ukuzinza kwentambo yokubhoboza ngesikhathi sokusebenza

· Izakhiwo zokusika ezingenhla nezingezansi zingafinyelela ukuphinda kuvuselelwe okuhle noma ukuhlenga kabusha okuhlanekezelwe

· Ingasetshenziselwa ukugqoka i-borehole ngaphambi kokugawulwa kukagesi, ukugijima kwe-casing kanye ne-expansion packer

· Ukunciphisa noma ukuqeda imilenze yenja encane

· Yehlisa isikhathi sokuvuselela kanye nenani lemithombo
