Ukusetshenziswa kwe-CMC ku-Drilling Fluid

I-Carboxymethyl Cellulose CMC iyimpuphu emhlophe ye-flocculent enokusebenza okuzinzile futhi iyancibilika kalula emanzini. Ikhambi liwuketshezi olungathathi hlangothi noma lwe-alkaline olusobala, oluhambisana namanye ama-glues ancibilikisa amanzi nama-resins. Umkhiqizo ungasetshenziswa njenge-adhesive, umkhulu, umenzi we-ejenti, e-emulsifier, i-emulsant, i-stabilizer, i-agentbox, njll.

Iqhaza le-carboxymethyl cellulose CMC: 1 2 3. Ukudonsa udaka, njengokumiswa kokumiswa nokusabalalisa, kunempilo eshalofini. Ukungeza i-CMC kungenza ukuthi zinzile futhi kunwebe impilo yeshalofu. 4. Udaka oluqukethe i-CMC akuvamile ukuthintwa isikhunta, ngakho-ke akudingekile ukugcina inani eliphakeme le-PH futhi lisebenzise amatatifomu. I-5. Kuqukethe i-CMC njenge-ejenti yokwelashwa yokushayela udaka oludonsela amanzi, olungamelana nokungcoliswa kosawoti ohlukahlukene oncibilikayo. I-6. I-CMC-equkethe udaka inokuqina okuhle futhi inganciphisa ukulahleka kwamanzi noma ngabe izinga lokushisa lingaphezulu kuka-150 ° C. I-CMC ene-viscosity ephezulu futhi i-degree ephezulu yokufaka esikhundleni ilungele udaka olunobunzima obuphansi, kanye ne-cmc enokubonakala okuphansi kanye nezinga eliphakeme lokufaka esikhundleni semali lilungele udaka ngobuningi obukhulu. Ukukhethwa kwe-CMC kufanele kunqunywe ngokuya ngezimo ezahlukahlukene njengohlobo lodaka, indawo, kanye nokujula okuhle.

Ukusetshenziswa kwe-CMC ku-Drilling Fluid

I-CMC ukulahleka okuhle koketshezi. Ukungeza odakeni kuzokhulisa ukubonakala kwesigaba se-liquid, ngaleyo ndlela kwandise ukumelana kwekhasi le-filtrate, ngakho ukulahleka kwamanzi kuzoncishiswa.

Ukungezwa kwe-CMC kwenza i-MUD ikhekhe eliminyene, elinzima futhi elibushelelezi, ngaleyo ndlela linciphise umkhuba we-jamming wengcindezelo yokuhlunga kanye nokubamba ithuluzi ekude, ukunciphisa isikhathi sokumelana nenduku ejikelezayo ejikelezayo futhi kudalule umkhathi wokukhulisa emthonjeni.

Ngomdaka jikelele, inani lomkhiqizo we-CMC Medium Viscous ngu-0.2-0.3%, futhi ukulahleka kwamanzi we-API kuncishisiwe kakhulu.

2. I-Rock ethuthukisiwe ephethe umphumela futhi yandisa ukuqina kodaka.

Ngoba i-CMC inekhono elihle lokuqina, esimweni sokuqukethwe okuphansi kwenhlabathi, engeza inani elifanele le-CMC kwanele ukugcina i-viscosity edingekayo ukuthwala ukusikwa nokumisa uBite, futhi kuthuthukise ukuqina kodaka, futhi kuthuthukise ukuqina kodaka.

3. Yenqaba ukuhlakazwa kobumba futhi usize ukuvikela ukuwa

Ukulahleka kwamanzi kwe-CMC kunciphisa ukusebenza kwehlathi kwe-hydration yodaka odongeni kahle, kanye nomphumela wokumboza we-CMC amaketanga ama-CMC eWall Rock uqinisa i-rock deak futhi wenza kube nzima ukusula bese uyawa.

4. I-CMC i-ejenti yokwelashwa ye-mud ngokuhambisana okuhle

I-CMC ingasetshenziswa ngokubambisana nama-ejenti entengo ahlukahlukene odakeni lwezinhlelo ezahlukahlukene, futhi ithola imiphumela emihle.

5. Ukusetshenziswa kwe-CMC ku-Cecting Spacer Fluid

Ukwakhiwa okujwayelekile komjovo we-Cement kanye nokwenza uCement kuyingxenye ebalulekile yokuqinisekisa ikhwalithi yokumanzisa. Uketshezi lwe-spacer olulungiselelwe yi-CMC lunezinzuzo zokunciphisa ukugeleza okuncishisiwe nokwakhiwa okulula.

6. Ukusetshenziswa kwe-CMC ku-Workover fluid

Ekuhlolweni kwamafutha nasekusebenzeni kokudla, uma kusetshenziswa udaka oluphezulu, kuzodala ukungcoliswa okukhulu kungqimba kawoyela, futhi kuzoba nzima kakhulu ukuqeda lokhu kungcoliseka. Uma amanzi ahlanzekile noma i-brine isetshenziswa nje njengoketshezi lwe-Workveover, kuzokwenzeka okunye ukungcola okukhulu. Ukulahleka kwamanzi okuvuvukala nokuhlunga kanye nohlu lwamawoyela kuzodala into yokukhiya amanzi, noma ibangele ukuba yingxenye enodaka engxenyeni kawoyela ukuze wandise, futhi anikeze ukubhekelwa phansi kongqimba kawoyela, futhi alethe uchungechunge lobunzima emsebenzini.

I-CMC isetshenziswa e-Workover fluid, engaxazulula ngempumelelo izinkinga ezingenhla. Ngemithombo yengcindezi ephansi noma izicindezi eziphakeme, ifomula ingakhethwa ngokuya ngesimo sokuvuza:

Ungqimba oluphansi lwengcindezi: ukuvuza okuncane: amanzi ahlanzekile + 0.5-0.7% CMC; Ukuvuza okujwayelekile: Amanzi Ahlanzekile + 1.09-1.2% CMC; Ukuvuza okukhulu: amanzi ahlanzekile + 1.5% CMC.
