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. , njenge-viscosity ephezulu kakhulu okanye amandla okucheba.
Udaka oluqulethe i-CMC lunokuxhathisa ubushushu obuphezulu, kwaye ngokubanzi lunokusetyenziswa kwindawo yobushushu obuphezulu obumalunga ne-140°C, njengeemveliso ezithatha indawo ephezulu kunye ne-viscosity ephezulu, lunokusetyenziswa kwindawo yobushushu obuphezulu be-150-170. °C.
Udaka oluqulathe i-CMC luyaxhathisa kwityuwa.Iimpawu zeCMC ngokwemigaqo yokuxhathisa ityuwa zezi: kungekuphela nje ukugcina isakhono esilungileyo sokunciphisa ilahleko yamanzi phantsi koxinzelelo oluthile lwetyuwa, kodwa inokugcina ipropathi ethile ye-rheological, enotshintsho oluncinci xa ithelekiswa naleyo kwindawo yamanzi acocekileyo. ;kukokubini Ingasetyenziswa kulwelo lokugrumba olungenadongwe kunye nodaka kwindawo engqonge amanzi anetyuwa.Ezinye iilwelo zokomba zisenako ukumelana netyuwa, kwaye iipropathi zerheological 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.
