Yintoni i-hec ekuthambekeni?

Hec, okanye i-hydroxyyl seluplose, yi-polymer engeyiyo i-ionic, i-polymer enyibilikayo emanzini ethathwe kwi-sellulose. Kwimeko yokugrumba, ngakumbi ukuhlolwa kweoyile kunye negesi, i-HEC idlala indima ebalulekileyo ekwandiseni ukusebenza kunye nokusebenza kwempumelelo kwe-fluids. Ezi zinxibo, zihlala zibhekiswa kuzo njengodaka oluhle, zibalulekile kwimisebenzi eyahlukeneyo, kubandakanya ukupholisa kwaye kuthathe i-drill bit, iphethe uxinzelelo kumphezulu, nokuzinzisa i-hydbore.

Ubume bekhemikhali kunye neepropathi ze-hec
I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheetheetheetheethl iveliswa ngokusabela kwi-seluplose ethylene oxide. Isiphumo siyipolymer eneyunithi ephindaphindayo ezibandakanya zombini i-hydrophilic (enomtsalane wamanzi) kunye ne-hydrophobic (ephindaphinda amanzi). Esi sakhiwo sahlukileyo sidlulisela iipropathi ezininzi:

I-Solubaty yaManzi: I-HEC inyibilikisa ngokulula kumanzi abandayo okanye ashushu, yenza isisombululo seColoidal.
UKWENZA IMPAHLA YOKUGQIBELA
Uzinzo: Izisombululo zeheks ziyazinza malunga ne-PH ye-PH 2-12) kwaye inokunyamezela iityiwa ezahlukeneyo kunye nee-elektrolytes.
Isakhono sokwenza ifilimu: Icacile, icacile, inzima, kwaye iguquguqukayo xa yomisa.
Imeko engeyiyo i-ionic: ukuba yi-ionic, hec ayisebenzi nezinye izinto ze-Ionic kwi-fluid fluid, iqinisekisa uzinzo.

Indima ye-HeC kwiintshukumo zokuntywila
Ukuntywila i-fluids, okanye ukuntywila kodaka, kubaluleke kakhulu kwinkqubo yokuqhuba. Benza imisebenzi emininzi ephambili, kunye nokufakwa kwe-hec exhasa kakhulu ukusebenza kwabo kwezi ndlela zilandelayo:

1. Ulawulo lwe-viscosity
I-HEC isetyenziswa ngokuyintloko ekuthandeni ulwelo ukulawula i-viscosity. I-viscosity ye-fluid fluid ibalulekile ekunqunyanyisweni nasekuhanjisweni kwe-Drill cutrengs ukuya kumphezulu. Ngokuhlengahlengisa uxinzelelo lwe-hec, abaqhubi banokulinganisa i-vickosity ye-fluid fluid ukuba itshatise iimfuno ezithile zokusebenza. Olu lawulo lunceda ukugcina ukusebenza kwenkqubo yokuqhuba kunye nokuthintela imiba efana nokuthengiswa kwemitha.

2. Ulawulo oluqhelekileyo
Ekufeni, ukuthotywa kubhekisele kwinkqubo apho inxenye yolwelo lwe-stid ivuza kwindawo ejikelezileyo, ishiya ikhekhe lokucoca. Ikhekhe lokucoca ngokufanelekileyo linciphisa ilahleko yokuntywila kwaye isebenzise iqula. I-HEC inceda ekunciphiseni inqanaba elililo ngokwenza ikhekhe elicekeceke kodwa lelokishino kwiindonga zequla, ezithintela ilahleko ye-nyibid kwaye zizinzayo.

I-3. Ukuthambisa
I-HEC inegalelo kwiipropathi ezityhafisayo zokwenza ulwelo. Ukucoca okusebenzayo kunciphisa ukungqubana phakathi komtya we-drill kunye nequla, enciphisa ukunxiba kunye nokukrazula kwizixhobo zokuntywila kwaye kuthintele iimeko ezibambe imibhobho. Olu hlaselo luyingenelo ikakhulu ekunciphiseni nasekuthetheleleni apho unxibelelwano luphakathi komtya we-drill kunye nequla le-quobore libhengeziwe.

I-4. Ukuzinza kwe-Wellbore
Ingqibelelo yolwakhiwo ye-qulebore ibalulekile kwimisebenzi ekhuselekileyo nenempumelelo. I-HEC inceda ukuzinzisa iqula ngokunciphisa ukuhlaselwa kweencindi zokuqhuba kumilo, ngaloo ndlela kuncitshiswa umngcipheko wokuwa kwe-Welybore. Amandla akhe efilimu anceda ekutyhaleni iqhekeza elincinci kunye neepores kubumbeko, ngakumbi igalelo kuzinzo olukhuselekileyo.

5. Ukuqwalaselwa kokusiNgqongileyo kunye nokhuseleko
I-Hec yi-polymer enganetyhefu kunye ne-biodegradable, esenza ukuba kuthelekiswa nobuhlobo bendalo xa kuthelekiswa nezinye izinto zokuntywila. Ukusetyenziswa kwayo kwimisebenzi yokuqhuba kuyanceda ukunciphisa i-Loffint yeNdawo, ukuqinisekisa ukubamba okukhuselekileyo kunye nokuzinza okuzinzileyo.

Iindidi kunye namabakala e-hec esetyenziswe ekuthandeni
Kukho amabakala ohlukeneyo e-hec, nganye ilungiselelwe izicelo ezithile kunye neemfuno zomsebenzi. Ukukhethwa kwenqanaba le-hec efanelekileyo kuxhomekeke kwizinto ezinje nge-viscofity oyifunayo, uzinzo lobushushu, kunye neemeko ezithile zokuqhuba. Ngokuqhelekileyo, i-hec yahlulwahlulwa ngokusekwe kubunzima bemolekyuli kunye nenqanaba lokufakwa endaweni (indlela apho amaqela e-hydroxyl kwi-sellulose athathelwa indawo ngamaqela e-hydroxyyl).

Amabakala okwazisa amabakala: Isetyenziswe kwizicelo ezifuna ukuphuculwa kwe-viscofity ebalulekileyo.
Amabakala e-viscosity ye-viscosity: Nikezela ngolungelelwano phakathi kwe-viscofity kunye nokukhulula okuphathelele.
Amabakala e-Viscosity ye-Viscosity: ilungele iimeko apho kufuneka uhlengahlengiso lwe-viscosity olufunekayo.
Iindlela zokusebenza kunye nezona ndlela zibalaseleyo
Ukusetyenziswa kwe-hec ekuthambekeni kulwelo kubandakanya ukuqwalaselwa ngononophelo kwenkqubo yoxinzelelo, iinkqubo zokuxuba, kunye nokuhambelana nezinye izongeziweyo. Ezinye izinto ezilungileyo zibandakanya:

Ukuxuba okufanelekileyo: I-HEC kufuneka yongezwe ngokuthe ngcembe kwi-fluid ngelixa ishukumisa ngokuqhubekayo ukuthintela ukwakhiwa kwe-hump kwaye kuqinisekiswe ukwahlukana.
Ulawulo loXolo: Ukugxininiswa kwe-HEC kufanele ukuba kufezekiswe ukufezekisa iipropathi ezinqwenelekayo ngaphandle kokuthambisa kakhulu ulwelo, olunokubangela imiba efana noxinzelelo olukhulu lwempompo.
UVAVANYO LOKWENZIWA: NGOKWENZA I-HEC ukuya kwi-Sleid yokumba, kubalulekile ukuvavanya ukuhambelana kwawo nezinye izongezo ukuthintela ukuphendula okungafunekiyo.

Imiceli mngeni kunye nezisombululo
Ngelixa i-HCC ibonelela ngezibonelelo ezininzi, kukho imiceli mngeni enxulumene nokusetyenziswa kwayo kwiintshukumo zokuntywila:

Imvakalelo yobushushu: Uhlobo lwe-hec lunokuchaphazeleka kukutshintsha kobushushu. Amaqondo obushushu aphezulu anokunciphisa ukubonwa kwezisombululo ze-Hec, ezinokuthi zenze ukuba kusetyenziswe amabakala anokuzinza ngobushushu okanye ezongeziweyo ezongeziweyo.
Ukonakaliswa kwe-Shear: Hec kungakwazi ukuthoba ukonakaliswa kwemeko ephezulu ye-Shear, okhokelela ekuphulukaneni ne-viscofity. Ukusebenzisa amabakala azinzileyo kunye neendlela ezifanelekileyo zokuphatha kunokunciphisa lo mba.
Ukuqwalaselwa kweendleko: Hec kunokubabiza kakhulu kunezinye izinto ezongeziweyo. Nangona kunjalo, ukusebenza kwayo kunye nezibonelelo zayo zokusingqongileyo zihlala zithetha iindleko.

I-HydroxyEteetheetheetheetheethy (Hec) licandelo elibalulekileyo kwiincindi zokuqhuba zanamhlanje, zibonelela ngolawulo lwe-viscofity, ukuncitshiswa kwesiqulatho, i-qubrication, kunye nokuzinza kwe-cedbore. Imeko yayo engenatyhefu kunye ne-biodegraday yenza ukhetho olunobuhlobo lwendalo kwimisebenzi yokuqhuba. Ngokuthobela iipropathi zayo, iindlela zokufunda, kunye nemiceli mngeni, abaqhubi banokunyusa i-HEC kunye nokukhuseleka kwemisebenzi yabo yokuqhuba.
