Yintoni izongezo zesamente kwaye yintoni isicelo?

I-samente ixhasa kwaye ikhusela ii-casings kakuhle kwaye inceda ukufezekisa ukwahlukaniswa kwendawo.Okubaluleke kakhulu kukhuseleko olukhuselekileyo, oluvakalayo lokusingqongileyo, kunye namaqula anengeniso, ukwahlukaniswa kwendawo kuyadalwa kwaye kugcinwe kumthombo ngenkqubo yesamente.Ukwahlukaniswa kwendawo kuthintela ulwelo olufana namanzi okanye igesi kwindawo enye ekubeni lungaxutywa ne-oyile kwenye indawo.Oku kuphunyezwa ngokudala umqobo we-hydraulic phakathi kwe-casing, i-samente kunye nokwakheka.Izongezo zesamente zizinto ezongeziweyo kwisamente ukwenzela ukuphuculwa kweempawu zesamente kunye nenkqubo yokugaya isamente.Izongezo zesamente zihlelwa ngokwamaqela emveliso ahlukeneyo afana nezincedisi zokusila, izixhasi zamandla kunye neziphuculi zokusebenza.Zimbini iindidi zemisebenzi esisiseko kwisamente, ezizezi, ukufakwa kwesamente okusisiseko nokwesibini.I-cementing ephambili ilungisa i-casing yensimbi ekubunjweni okujikelezayo.I-cementing yesibini isetyenziselwa ukuzalisa iifom, ukutywinwa, okanye ukuvala amanzi.Ukusebenza kunokwahluka ngokongezwa kwezongezo ngokubhekiselele kwimiba eyahlukeneyo.Ngokuxhomekeke ekusetyenzisweni kwesamente, iintlobo ezininzi zezongezo zingabandakanywa.Ezi ziquka i-accelerators, i-retarders, i-dispersants, i-exteners, i-weighting agents, i-gels, i-foamers, kunye ne-additives yokulahlekelwa kwamanzi.I-Foring Chemcials ibonelela ngoluhlu olubanzi lwezongezo zekhemikhali ezikumgangatho ophezulu ezikhethekileyo zosetyenziso lwe-oilfield kwaye zibonelela ngoyilo olwenzelwe ukuxhasa kunye nokuphucula inkqubo yesamente.I-samente dispersants iphucula i-slurry rheology ukwenzela ukuba ukupompa okude kuphuculwe kakhulu kwaye kwangaxeshanye i-slurries ye-cement encitshisiweyo yamanzi inokwenzeka.Izongezo zokulahleka kwe-Fluid, ezizinzile ngokuchasene nokushisa okuphezulu kunye nezisombululo zetyuwa ezigxininisiweyo, ziqinisekisa umsebenzi othembekileyo wokumisa phantsi kweemeko ezinzima.Iiretaretha zinokudityaniswa ngokudibeneyo kunye nezisasazi zethu ezisebenza kakuhle zivumela ixesha elibalulekileyo lemisebenzi yokusamente phantsi kweemeko zobushushu obuphezulu.Izongezo ezichasayo zokufuduka kwerhasi zithintela irhasi ukuba ingahambi ngomjelo kwisamente eqinile kwaye iqinisekise umsebenzi othembekileyo wesamente, ngelixa ii-defoam zethu zineempawu ezibalaseleyo zokulawula ugwebu.
