Ngabe i-blade ye-casing scraper iphuma kanjani ngemva kokugijima umthombo?

Ngemva kwei-casing scrapergijima uye emthonjeni, ngokuvamile uzonwetshwa ngesakhiwo esithile somshini. Inqubo ethile yokusebenza ingase ibe nomehluko othile, kodwa ngokuvamile ihlanganisa lezi zinyathelo ezilandelayo:

Ukulungiselela: Ngaphambi kokusebenzisa umthombo, hlola isimo se-blade se-scraper ukuze uqinisekise ukuthi akukho monakalo noma ukugqoka, qinisekisa ukuthi uxhumano phakathi kwe-blade kanye ne-casing scraper ayikhululekile noma yonakaliswa.

Faka i-scraper: Xhuma i-scraper kumathuluzi we-downhole futhi uyivikele nge-nati noma enye idivayisi yokubamba. Qinisekisa ukuthi uxhumano lwe-wiper luvikelekile ukuze uvimbele ukuxega noma ukuzungezisa ngesikhathi sokusebenza.

Izindlela zokunweba zokusebenza: Ama-casing scrapers ngokuvamile anezinqubo zokunweba zemishini ezisetshenziselwa ukulawula ukunwetshwa nokuhoxiswa kwe-blade. Indlela yokusebenza ingahluka kuye ngohlobo lwe-scraper, kodwa ngokuvamile isebenza ngenye yalezi zindlela ezilandelayo:

a. I-Rotary: Ngokuzungezisa ingxenye engenhla yethuluzi noma ngepulaki exhunyiwe, i-blade izozungeza ngokwewashi noma i-counterclockwise ukuze i-blade iphume kusukela phansi kwe-scraper.

b. I-Push-pull: I-scraper blade iphushwa ngaphandle noma idonswe emuva kusukela phansi kwe-scraper ngokuphusha nokudonsa ingxenye engaphezulu yethuluzi lomthombo noma ngepulaki exhunyiwe.

c. I-Hydraulic noma i-pneumatic: Ngesistimu ye-hydraulic noma ye-pneumatic, lawula ukunwetshwa nokunwetshwa kwe-scraper blade. Ngokulawula i-valve, uketshezi noma igesi kungenziwa ukuze kwenziwe i-scraping blade inwebe noma ihoxise.

Isandiso se-Blade:Ngokusho komklamo we-scraper, ngokusebenzisa ukusebenza okufanelekile kwendlela yokwandisa, yenza umsebenzi ohambisanayo ukuze wenze i-blade ifinyelele endaweni oyifunayo. Ukuzungezisa, ukusunduza nokudonsa, noma amandla we-hydraulic/aerodynamic ngokuvamile asetshenziselwa ukuzuza ukunwetshwa kwe-blade.

Ukusebenza kokukhuhla: Uma i-blade inwetshiwe endaweni, umsebenzi wokukhuhla ungenziwa. I-blade ye-scraper isusa i-sediment nesikali esinamathiselwe olwelweni lwe-casing ukuze luhlanze futhi luhlale luvulekile.

Ukuqinisekisa ukuphepha nokusebenza kahle komsebenzi, opharetha kufanele ajwayele imiyalelo yokusebenza ye-scraper futhi asebenze ngokuhambisana nezinqubo zokusebenza eziphephile ezifanele. Ngaphezu kwalokho, izinto zokusebenza namathuluzi kufanele kugcinwe kusesimweni esihle futhi noma yimaphi amazinga okuphepha asebenzayo kanye nemithethonqubo kufanele kuqashelwe ngaphambi kokusebenza kwemigodi.
