Ukusetyenziswa kwe-sodium carboxymethyl cellulose kulwelo lokugrumba

I-Sodium carboxymethyl cellulose (CMC-Na ngamafutshane) yinxalenye ebalulekileyo yepolymer enyibilikayo emanzini kwaye isetyenziswa kakhulu kulwelo lokugrumba ioyile. Iimpawu zayo ezikhethekileyo zenza ukuba ibe yinxalenye ebalulekileyo kwinkqubo yolwelo lokugrumba.

1. Iipropati ezisisiseko ze-sodium carboxymethyl cellulose

I-Sodium carboxymethyl cellulose yi-anionic cellulose ether eveliswa yi-cellulose emva konyango lwe-alkali kunye ne-chloroacetic acid. Ulwakhiwo lwayo lwe-molecular luqulathe inani elikhulu lamaqela e-carboxymethyl, nto leyo eyenza ukuba ibe nokunyibilika kwamanzi okuhle kunye nozinzo. I-CMC-Na inokwenza isisombululo esinobukrakra obuphezulu emanzini, esineempawu zokutyeba, ukuzinza kunye nokwenza ifilimu.

Isithambisi

I-CMC-Na isetyenziswa njengesithambisi kulwelo lokugrumba. Umsebenzi wayo ophambili kukwandisa ubungqindilili bolwelo lokugrumba nokuphucula amandla alo okuthwala iziqwenga zamatye kunye neziqwenga zokugrumba. Ubungqindilili obufanelekileyo bolwelo lokugrumba bunokuthintela ngempumelelo ukudilika kodonga lomngxuma nokugcina uzinzo lomngxuma.

Isinciphisi sokulahleka kolwelo

Ngexesha lenkqubo yokugrumba, ulwelo lokugrumba luya kungena kwiimbobo zokwakheka, nto leyo ebangela ukulahleka kwamanzi kulwelo lokugrumba, olungachithi nje kuphela ulwelo lokugrumba, kodwa lunokubangela ukudilika kodonga lomngxuma kunye nomonakalo wedama. Njengento yokunciphisa ukulahleka kolwelo, i-CMC-Na inokwenza ikhekhe lesihluzo esixineneyo eludongeni lomngxuma, inciphise ngempumelelo ukulahleka kokucoca kolwelo lokugrumba kwaye ikhusele ukwakheka kunye nodonga lomngxuma.

Isithambisi

Ngexesha lenkqubo yokugrumba, ukungqubana phakathi kwento yokugrumba kunye nodonga lomthombo kuya kuvelisa ubushushu obuninzi, nto leyo ebangela ukuguguleka okwandileyo kwesixhobo sokugrumba. Ukutyeba kwe-CMC-Na kunceda ekunciphiseni ukungqubana, ukunciphisa ukuguguleka kwesixhobo sokugrumba, kunye nokuphucula ukusebenza kakuhle kokugrumba.

Isizinzisi

Ulwelo lokubhola lunokutyibilika okanye luwohloke xa kushushu kakhulu kwaye kuxinzelelo oluphezulu, ngaloo ndlela lulahlekelwe ngumsebenzi walo. I-CMC-Na izinzile kakuhle kubushushu kwaye inokumelana netyuwa, kwaye inokugcina uzinzo lolwelo lokubhola phantsi kweemeko ezinzima kwaye yandise ubomi bayo benkonzo.

3. Indlela yokusebenza kwe-sodium carboxymethyl cellulose

Ukulungiswa kokubonakala

Ulwakhiwo lwemolekyuli ye-CMC-Na luqulathe inani elikhulu lamaqela e-carboxymethyl, anokwenza iibhondi ze-hydrogen emanzini ukuze kwandiswe i-viscosity yesisombululo. Ngokulungisa ubunzima be-molekyuli kunye ne-degree yokutshintshwa kwe-CMC-Na, i-viscosity yolwelo lokubhola ingalawulwa ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokubhola.

Ulawulo lokuhluza

Iimolekyuli ze-CMC-Na zinokwenza isakhiwo senethiwekhi esinemilinganiselo emithathu emanzini, esinokwenza ikhekhe lesihluzo elixineneyo eludongeni lomthombo kwaye sinciphise ukulahleka kokuhluzwa kolwelo lokubhola. Ukwakheka kwekhekhe lesihluzo akuxhomekanga kuphela kuxinzelelo lwe-CMC-Na, kodwa nakubunzima bayo beemolekyuli kunye nenqanaba lokutshintsha.

Ukuthambisa

Iimolekyuli zeCMC-Na zinokufunxwa phezu kwento yokubhola kunye nodonga lomthombo emanzini ukuze zenze ifilimu yokuthambisa kunye nokunciphisa i-friction coefficient. Ukongeza, iCMC-Na inganciphisa ngokungathanga ngqo i-friction phakathi kwento yokubhola kunye nodonga lomthombo ngokulungisa i-viscosity yolwelo lokubhola.

Uzinzo lobushushu

I-CMC-Na inokugcina uzinzo lwesakhiwo sayo se-molecular phantsi kweemeko zobushushu obuphezulu kwaye ayithambekeli ekuwohlokeni kobushushu. Oku kungenxa yokuba amaqela e-carboxyl kwii-molecules zayo anokwenza iibhondi ze-hydrogen ezizinzileyo kunye nee-molecules zamanzi ukuze zimelane nomonakalo wobushushu obuphezulu. Ukongeza, i-CMC-Na ikwanokumelana okuhle netyuwa kwaye inokugcina ukusebenza kwayo kwi-saline formations. 

4. Imizekelo yokusetyenziswa kweSodium Carboxymethyl Cellulose

Kwinkqubo yokwemba yokwenyani, isiphumo sokusetyenziswa kwe-sodium carboxymethyl cellulose siyamangalisa. Umzekelo, kwiprojekthi yokugrumba imigodi enzulu, inkqubo yolwelo lokugrumba equlethe i-CMC-Na yasetyenziswa ukulawula ngokufanelekileyo uzinzo kunye nokulahleka kokuhluzwa kwe-wellbore, ukwandisa isantya sokugrumba, kunye nokunciphisa iindleko zokugrumba. Ukongeza, i-CMC-Na ikwasetyenziswa kakhulu ekugrumbeni olwandle, kwaye ukumelana kwayo netyuwa kakuhle kwenza ukuba isebenze kakuhle kwindawo yolwandle.

Ukusetyenziswa kwe-sodium carboxymethyl cellulose kulwelo lokugrumba kubandakanya ikakhulu iinkalo ezine: ukuqina, ukunciphisa ukulahleka kwamanzi, ukuthambisa kunye nokuzinza. Iimpawu zayo ezizodwa zomzimba nezekhemikhali zenza ukuba ibe yinxalenye ebalulekileyo kwinkqubo yolwelo lokugrumba. Ngophuhliso oluqhubekayo lwetekhnoloji yokugrumba, amathuba okusetyenziswa kwe-sodium carboxymethyl cellulose aya kuba banzi. Kuphando oluzayo, ulwakhiwo lweemolekyuli kunye neendlela zokuguqula ze-CMC-Na zinokulungiswa ukuphucula ukusebenza kwayo ngakumbi kwaye kuhlangatyezwane neemfuno zeendawo zokugrumba ezintsonkothileyo.
