Iphuma njani iblade ye-casing scraper emva kokuqhuba iqula?

Emva kwei-casing scraperbaleka ukuya equleni, iyakwandiswa ngokubanzi ngesakhiwo esithile somatshini. Inkqubo ethile yokusebenza inokuba nomahluko othile, kodwa ibandakanya la manyathelo alandelayo:

Ukulungiselela: Ngaphambi kokuba usebenze iqula, jonga imeko ye-blade ye-scraper ukuqinisekisa ukuba akukho monakalo okanye ukugqoka, qinisekisa ukuba ukudibanisa phakathi kwe-blade kunye ne-casing scraper ayikhululekile okanye yonakaliswe.

Faka i-scraper: Xhuma i-scraper kwi-downhole izixhobo kwaye uyikhusele nge-nut okanye esinye isixhobo sokubamba. Qinisekisa ukuba uqhagamshelo lwe-wiper lukhuselekile ukukhusela ukukhulula okanye ukujikeleza ngexesha lokusebenza.

Iindlela zokwandisa ukusebenza: I-Casing scrapers ngokuqhelekileyo ineendlela zokwandisa oomatshini ezisetyenziselwa ukulawula ukwandiswa kunye nokuhoxiswa kwe-blade. Indlela yokusebenza inokwahluka ngokuxhomekeke kuhlobo lwe-scraper, kodwa bahlala besebenza ngenye yezi ndlela zilandelayo:

a. I-Rotary: Ngokujikeleza inxalenye ephezulu yesixhobo okanye ngeplagi edibeneyo, i-blade iya kujikeleza i-clockwise okanye i-counterclockwise ukwenzela ukuba i-blade ibambelele phantsi kwe-scraper.

b. I-Push-tsali: I-blade ye-scraper ityhalwa ngaphandle okanye itsalwe umva ukusuka ezantsi kwe-scraper ngokutyhala kunye nokutsala indawo ephezulu yesixhobo somthombo okanye ngeplagi edibeneyo.

c. I-Hydraulic okanye i-pneumatic: Ngokusebenzisa i-hydraulic okanye i-pneumatic system, lawula ukwandiswa kunye nokwandiswa kwe-scraper blade. Ngokulawula i-valve, ulwelo okanye igesi ingangeniswa ukwenza i-scraping blade yandise okanye ihoxise.

Ukongezwa kweBlade:Ngokutsho koyilo lwe-scraper, ngokusebenza okufanelekileyo kwendlela yokwandisa, yenza umsebenzi ohambelanayo ukwenza i-blade yandise kwindawo oyifunayo. Ukujikeleza, ukutyhala kunye nokutsalwa, okanye i-hydraulic / aerodynamic force idla ngokusetyenziselwa ukufikelela ukwandiswa kwe-blade.

Umsebenzi wokukrala: Emva kokuba i-blade yandisiwe kwindawo, umsebenzi wokukrala unokwenziwa. I-blade ye-scraper isusa intlenga kunye nesikali esiqhotyoshelwe kwi-lining ye-casing ukuyicoca kwaye igcine ivulekile.

Ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle komsebenzi, umqhubi kufuneka aqhelane nemiyalelo yokusebenza ye-scraper kwaye asebenze ngokuhambelana neenkqubo ezifanelekileyo zokusebenza ezikhuselekileyo. Ukongeza, izixhobo kunye nezixhobo kufuneka zigcinwe zisemgangathweni kwaye nayiphi na imigangatho yokhuseleko esebenzayo kunye nemimiselo kufuneka igcinwe ngaphambi kokusebenza kwe-downhole.
