Kushandiswa kweCMC mukukwevera mvura

CarboxyMethyl Cellelose CMC ndeye chena flucculent poda nehuremu hwakagadzikana uye rinopenya mumvura. Mhinduro ndeyekusarerekera kana alkaline yakajeka viscous mvura, iyo inoenderana nedzimwe gluluble glues uye inogara. Chigadzirwa chinogona kushandiswa sekunamatira, kunamatira, emulsifier, kuparadzira, kugarisana, etc. carbolose

Basa reCarboxyMethyl Cellerose C Compulose CMC: 1 2. Mushure mekuwedzera cmc kumatope, iyo yekukwevera inogona kuwana yakaderera shear shea simba, kuitira kuti madhaka anogona kusunungura gasi rakaputirwa mariri, uye panguva imwe chete, marara anogona kukurumidza kuraswa mugomba rematope. 3 Kuwedzera cmc kunogona kuita kuti ive yakagadzikana uye inowedzera hupenyu hwesherufu. 4 5. Iyo ine cmc seyekuchengetera mumiremba wekukwevera madhiri anofuridza mvura, iyo inogona kuramba kusvibiswa kwemakumbo akasiyana siyana ekusanzwisisika. 6 CMC neKudenga kweVanhukombe uye yakakwirira mwero wekutsiva yakakodzera matope ane yakaderera density, uye cmc neyekudzika viscosity uye yakakwirira viscosity uye yakakwirira mwero wekutsiva yakakodzera matope ane yakakura. Sarudzo yeCMC inofanira kutsanangurwa zvinoenderana nemamiriro ezvinhu akasiyana senge madhiri, nzvimbo, uye kudzika kwakadzika.

Kushandiswa kweCMC mukukwevera mvura

1.

CMC iri yakanaka fluid kurasikirwa kuderedza. Kuwedzera iyo mumatope kunowedzera zvimisikidzwa kwechikamu chemvura, nekudaro ndichikura kurwisa kwemitambo, saka kurasikirwa kwemvura kuchaderedzwa.

Kuwedzera kweCMC kunoita kuti matope dendei dense, nekuomarara uye nekukasira kuderedza phenomenon yekumanikidza kusimuka uye kuderedza nguva yekudzikisa tendering aluminium toluminium uye kuderedza chiitiko chekutakura mutsime mutsime.

Muzvakafanana madhaka, huwandu hweCMC yepakati viscous chigadzirwa ndeye 0.2-0.3%, uye kurasikirwa kwemvura, uye kurasikirwa kwemvura kwakawanda kwakaderedzwa.

2. Rakavandudzwa Dombo rinotakura maitiro uye yakawedzera madhaka kugadzikana.

Nekuti CMC ine kugona kwakanaka, mune yakaderera yekubvisa huwandu hweCMC yakakwana kuchengetedza viscosity inodiwa kutakura cuttings uye kumisa barite, uye kuvandudza madhaka kugadzikana.

3. Ramba kupararira kwevhu uye kubatsira kudzivirira kuparara

Kurasikirwa kwemvura kweCMC kuderedza kuita kweiyo hydration mwero shale patsime rematope, uye nekushambadzira kweCMC marefu emadziro

4

CMC inogona kushandiswa pamwe chete nevakaremara vakaremara mumatope evakashata masisitimu, uye vanowana mibairo yakanaka.

5. Kushandiswa kweCMC mukupasira spacer fluid

Iko kuvakwa kwakajairika kwekusimbisa kwakanyanya uye simende jekiseni chikamu chakakosha kuve nechokwadi chekusimanikidza. Iyo spacer fluid yakagadzirirwa ne cmc ine zvakanakira kuderedzwa kuyerera kupesana nekuvakwa kwakakodzera.

6. Kushandiswa kweCMC mu Workover Fluid

Muchiitiko chemafuta uye mashandiro ekushanda, kana madhaka akakwirira anoshandiswa, zvichakonzera kusvibiswa kwakakomba kuofa, uye zvichave zvakaoma kubvisa idzi kusvibiswa. Kana mvura yakachena kana brine ichingoshandiswa seyekurovedza muviri, kusvibiswa kwakakomba kuchaitika. Kupararira uye kurasikirwa kwemvura mumvura mumafuta kuchaita kuti mvura yekukiya phenomenon, kana kukonzera chikamu chine madhaka mumafuta kuti uwedzere kuwanda, isa simba reoya remafuta, uye uuye nematambudziko ebasa racho.

CMC inoshandiswa mu Workover Fluid, iyo inogona kubudirira kugadzirisa matambudziko ari pamusoro. Zvematsime akaderera-ekumanikidza kana matsime ekumanikidza, iyo formula inogona kusarudzwa zvichienderana nemamiriro ezvinhu okusunungura:

Low-Prontours Layer: Little Laakage: Mvura Yakachena + 0.5-0.7% CMC; Generage Lakage: Mvura Yakachena + 1.09-1.2% CMC; Kubhururuka kwakakomba: mvura yakachena + 1.5% cmc.
