Kuyadingeka ukusebenzisa imbobo yesikhala bese wenza imisebenzi yokufaka i-cement uma ubhoboza ujule oluthile. I-casing izofakwa ukuze kudalwe isithiyo se-annular. Ngemuva kwalokho i-cement slurry izophonswa phansi yi-driller; bese i-cement slurry iya phezulu bese igcwalisa i-annulus ibe phezulu kwe-cement (TOC). Ekusebenzeni kwe-cement ekhethekile, i-liquid cement slurry ikhiqiza ingcindezi ye-hydrostatic lapho ijikeleza phansi kwesikhala bese ikhuphuka i-annulus encane, okubangela ingcindezi ephezulu yokungqubuzana futhi kukhuphule ingcindezi yembobo engezansi.
Uma ingcindezi yembobo idlula izinga elijwayelekile, izophula ukwakheka futhi ibangele isigameko esilawulwa kahle. Ngemuva kwalokho i-slurry yesimende ingena ekwakhekeni. Ngokuphambene nalokho, ukucindezela okwanele kwembobo engezansi akwanele ukubamba ingcindezi yokwakheka. Ngenxa yalesi sizathu, kubalulekile ukusebenzisa ubuningi be-slurry obufanele kanye nesisindo sokucindezela ekujuleni okuthile, ukwethula isikhathi sangempela.imitha yobuningi be-slurry yesimendeukufinyelela ukunemba okulindelekile.
Imitha Yobuningi Be-Slurry Enconyiwe Nokufakwa
Ukunemba okuphezulu nokuzinzileimitha yobuningi be-ultrasonic engeyona eyenuzikuyindlela ekahle yokuqapha ubuningi ngesikhathi sangempela.ukuminyana kwe-simende slurrykunqunywa isikhathi sokudlulisa kusuka kumthumeli kuya kumukeli, ukususa ukuphazamiseka okuvela ku-slurry viscosity, ubukhulu bezinhlayiya kanye nokushisa.
Iimitha yobuningi obungeyona eyenuzi ku-inthanethiKunconywa ukuthi kufakwe eduze kwendawo yokufaka amanzi emapayipini omthombo, okuqinisekisa ukuthi ukufundwa okutholiwe kuyafana ukuze amanzi angene emgodini. Ngesikhathi esifanayo, amapayipi aqondile anele kokubili phezulu nangezansi komfulaimitha yobuningi be-ultrasonickunciphisa ithonya lezimo zokugeleza koketshezi.
Ubulula Okulethwa Amamitha Obuningi Obuqondile
Ukufundwa kobuningi be-slurry yesimende kungaqoqwa futhi kuboniswe ngesikhathi sangempela uma kuhlanganiswe ohlelweni lokulawula oluzenzakalelayo. Abasebenzi bavunyelwe ukubona ama-current density fluctuation current, amanani obuningi bamanje kanye nokuphambuka kusuka ku-density target esethiwe egumbini lokulawula eliphakathi.
Uhlelo lokulawula lulungisa ubuningi be-slurry ngokuzenzakalelayo ngemva kokuthola isignali ye-alamu, ngokusekelwe ezinhlelweni ezihleliwe. Ngamanye amazwi, indlela yokulawula impendulo isebenza ukwandisa ukufakwa kwamanzi noma izithasiselo. Ngokuphambene nalokho, isilinganiso sikasimende sizokhushulwa uma ubuningi buphansi kakhulu.
Izinzuzo ze-New Ultrasonic Density Meter
Imitha yobuningi engeyona eyenuzi ilinganisa ubuningi be-slurry yesimende ngesikhathi sangempela ngomsindo we-ultrasonic, engenazo imikhawulo evela eminyangweni yezemvelo. Ayinawo amagwebu noma amabhamuza ku-slurry. Ngaphandle kwalokho, ingcindezi yokusebenza, ukuguguleka koketshezi kanye nokugqwala ngeke kuthinte ukunemba kokukhishwa kokugcina. Okokugcina, izindleko eziphansi kanye nokuphila isikhathi eside kuyenza ithandwe phakathi kwamamitha amaningi obuningi angaphakathi njengomitha wobukhulu be-tuning fork, imitha yobukhulu be-Coriolis nokunye okunjalo.
