Ngexesha lokugaya, ukugaya kunye nokusebenza kweoli kunye negesi yendalo, udonga lomthombo luxhomekeke ekulahlekeni kwamanzi, okubangela utshintsho kwi-diameter yomthombo kunye nokuwa, ukwenzela ukuba iprojekthi ayikwazi ukuqhutyelwa ngokuqhelekileyo, okanye ishiywe phakathi. Ke ngoko, kuyafuneka ukuba kuhlengahlengiswe iiparamitha ezibonakalayo zodaka lokomba ngokotshintsho lweemeko zejoloji yommandla ngamnye, njengobunzulu, ubushushu kunye nobukhulu. I-CMC yeyona mveliso ilungileyo enokulungelelanisa ezi parameters zomzimba. Imisebenzi yayo ephambili yile:
Udaka oluqulathe i-CMC lunokwenza udonga lwequla lube yikeyiki ecekethekileyo, eqinileyo kunye nesezantsi-permeability yokucoca, enokuthintela ukuhanjiswa kwe-shale, ukuthintela ukusika ukugrumba ekuhlakazekeni, kunye nokunciphisa ukudilika kodonga lwequla.
Udaka oluqulethe i-CMC luhlobo lwe-arhente yokulawula ilahleko ephezulu, inokulawula ukulahleka kwamanzi kwinqanaba elingcono kwi-dosage ephantsi (0.3-0.5%), kwaye ayiyi kubangela iziphumo ezibi kwezinye iipropati zodaka , ezifana ne-viscosity ephezulu kakhulu okanye i-shear force.
Udaka olune-CMC lunokuxhathisa ubushushu obuphezulu, kwaye ngokuqhelekileyo lunokusetyenziswa kwindawo yobushushu obuphezulu obumalunga ne-140 ° C, njengezinto ezitshintshiweyo eziphezulu kunye ne-viscosity ephezulu, zingasetyenziswa kwindawo yobushushu obuphezulu be-150-170 ° C.
Udaka oluqulathe i-CMC luyaxhathisa kwityuwa. Iimpawu ze-CMC ngokwemiqathango yokumelana netyuwa zezi: kungekuphela nje ukugcina isakhono esihle sokunciphisa ilahleko yamanzi phantsi koxinaniso oluthile lwetyuwa, kodwa lunokugcina ipropati ethile ye-rheological, enotshintsho oluncinane xa kuthelekiswa naleyo kwindawo yamanzi acocekileyo; kukokubini Ingasetyenziswa kulwelo lokugrumba olungenadongwe kunye nodaka kwindawo yamanzi anetyuwa. Ezinye iilwelo zokomba zisenako ukumelana netyuwa, kwaye iimpawu ze-rheological azitshintshi kakhulu. Ngaphantsi kwe-4% yoxinaniso lwetyuwa kunye namanzi amatsha, umlinganiselo wokutshintsha kwe-viscosity ye-CMC enganyangekiyo yetyuwa iye yanda ibe ngaphezu kwe-1, oko kukuthi, i-viscosity ayinakuguqulwa ngokukhawuleza kwindawo enetyuwa eninzi.
I-CMC-equlethe udaka inokulawula i-rheology yodaka.CMCayikwazi ukunciphisa kuphela ukulahleka kwamanzi, kodwa ikhulise i-viscosity.
1. Udaka oluqulathe i-CMC lunokwenza udonga lwequla lube yikeyiki ebhityileyo, elukhuni nesezantsi ekwazi ukutyhutyha, ukunciphisa ilahleko yamanzi. Emva kokongeza i-CMC eludakeni, i-drilling rig inokufumana amandla aphantsi okucheba, ukuze udaka lukhulule ngokulula igesi ehlanganiswe kuyo, kwaye kwangaxeshanye, i-debris ingalahlwa ngokukhawuleza emhadini wodaka.
2. Njengezinye i-suspension dispersions, udaka lokwemba lunobomi obuthile beshelufu. Ukongeza i-CMC ingayenza izinze kwaye yandise ubomi beshelufu.
3. Udaka oluqulethe i-CMC alufane luchaphazeleke ngumbumba, kwaye akukho mfuneko yokugcina ixabiso le-pH eliphezulu kunye nokusetyenziswa kwezinto zokukhusela.
4. Udaka oluqulethe i-CMC lunozinzo oluhle kwaye lunokunciphisa ilahleko yamanzi nokuba ubushushu bungaphezu kwama-150 degrees.
