Ukuphuhliswa kweendawo ze-oyile kunye negesi yiprojekthi enzima kwaye ebanzi eyenziwe ukuhlola, ukugrumba, ukusebenza phantsi komhlaba, ukubuyiswa kweoli, ukuqokelela kunye nokuthutha.Ubuninzi beekhemikhali ziyafuneka kumsebenzi ngamnye.

Njengezinto ezincedisayo ezibalulekileyo zokuhlola i-geological, izongezo zokomba ziye zafundwa kwaye zisetyenziswa iminyaka emininzi ekhaya nakwamanye amazwe, kwaye amakhulu eemveliso ezinxulumene nazo ziye zaphuhliswa.

I-drilling fluid ikwaziwa ngokuba yi-drilling mud.Umsebenzi wayo kukuqhekeza i-core, ukuthwala izicucu, ukuthambisa i-cooling bit, ukulinganisela uxinzelelo lokubumba kunye nokukhusela i-wellbore. , kunye ne-arhente yonyango isitshixo sokuqinisekisa ukulungelelaniswa kodaka.I-Drilling fluid kunye ne-agent yonyango yokugqiba ulwelo i-akhawunti malunga nesiqingatha seekhemikhali ze-oilfield.

Idizayini yesamente yokufaka isamente

1. Farhente ilahleko luid

Izinto ezinokuthi zinciphise ilahleko yokuhluzwa kwe-sement slurry zibizwa ngokudibeneyo njengeejenti zokunciphisa ilahleko yamanzi kwi-sement slurry.Okwangoku, iiarhente zokunciphisa ilahleko zamanzi ezisetyenziswa ngokuqhelekileyo ziquka i-polyacrylamide, i-carboxymethyl cellulose kunye ne-organic acid compounds.

1. Tsala isinciphisi (diluent, dispersant, water reducer, turbulence regulator)

Ukumpompa okuguquguqukayo kwegrout kaninzi kunokuvelisa iziphumo ezanelisayo.I-Drag reducers ingakwazi ukulawula ukuhamba kwe-grout kwaye ibangele ukuhamba kwe-turbulent kumazinga epompo ephantsi.I-Sulfomethyl tannin, i-tannin lye kunye ne-sulfomethyl lignite inemiphumo emihle yokunciphisa i-drag kuluhlu oluthile lomxholo.

1. Ukutyeba ixesha regulator

Ngenxa yobunzulu obuhlukeneyo besamente, i-sement slurry iyafuneka ukuba ibe nexesha elifanelekileyo lokuqina ukuze lihlangabezane neemfuno zokusebenza ngokukhuselekileyo.

I-Thickening time regulators ibandakanya i-coagulant kunye ne-retarding spines.I-coagulant yi-additive enokwenza i-samente iqine ngokukhawuleza, i-calcium chloride esetyenziswa ngokuqhelekileyo, i-sodium chloride.I-Ammonium chloride, njl.Iiretarders ezisetyenziswa ngokuqhelekileyo ziquka i-lignosulfonates kunye ne-derivatives yazo, iityuwa ze-hydroxycarboxylic acids (ezifana ne-citric tartaric acid) kunye ne-derivatives yazo.

1. Umlawuli womxhuzulane othe ngqo

Ngokweemeko ezahlukeneyo zoxinzelelo lokwakheka, ukuxinana okuhlukeneyo kodaka lwesamente kuyadingeka.Izongezo ezinokutshintsha ubuninzi be-sement slurry zibizwa ngokuba ngabalawuli be-gravity ethile, kubandakanywa i-agent yokukhanyisa kunye ne-weighting agents.I-Lightening agents ziyi-bentonite (eyaziwa nangokuthi ukususwa komhlaba), i-asphalt enzima, njl njl. kwaye nangokunjalo.
