CMC inoshandisa muPetroleum uye Oiri Drilling Indasitiri

Sodium carboxymethyl cellulose (CMC) inogadzirwa neyechisikigo cellulose nekemikari shanduko yemvura-soluble cellulose ethers derivatives, imhando yakakosha yemvura-inonyungudika cellulose ether, chena kana yero hupfu kana granular, isiri-chepfu, isinganakidze, inogona kunyungudika. mumvura, ine kugadzikana kwakanaka kwekupisa uye kusagadzikana kwemunyu, yakasimba antimicrobial properties. Iyo slurry fluid yakagadzirirwa nechigadzirwa ichi ine yakanaka kurasikirwa kwemvura, inhibition uye yakakwirira tembiricha kuramba. Inoshandiswa zvakanyanya muindasitiri yekuchera mafuta, kunyanya mvura yemunyu Matsime uye kuchera mafuta ekumahombekombe.

Sodium carboxymethyl cellulose CMC sepolymer inonyungudika nemvura, inogona kukurumidza kunyungudika mumvura inotonhora kana mvura inopisa; Seyakakora mumiriri, rheological control agent, adhesive, stabilizer, inodzivirira colloid, suspension agent uye mvura yekuchengeta mumiriri, yakanaka yekuchera madhaka mushonga wekurapa uye kugadzirira kwekupedzisa fluid zvinhu mukuchera oiri. Iine high pulping rate uye yakanaka yemunyu kuramba. CMC yakanakisa kurasikirwa kwemvura yekudzikisa mumiriri wedhaka remvura yakachena uye dhaka remvura yegungwa rakazadza dhaka remunyu, uye ine yakanaka viscosity yekusimudza kugona uye yakakwirira tembiricha kuramba (150).℃) Inokodzera kugadzirwa kwemvura nyowani, yegungwa uye yakazara brine yekupedzisa zvinwiwa, uye uremu hwecalcium chloride hunogona kugadzirwa kune dzakasiyana densities yekupedzisa zvinwiwa, uye kupedzisa fluid viscosity uye kuderera kwemvura kurasikirwa.

Nhanganyaya yeCMC HV uyeCMC LV ye petroleum drilling fluid

(1) Madhaka eCMC anogona kuita kuti madziro emadziro aite mutete uye akasimba sefa keke ine yakaderera permeability, kuitira kuderedza kurasikirwa kwemvura.

(2)Mushure mekuwedzera CMC kumatope, chibooreso chinogona kuwana simba rekutanga rekugera, kuitira kuti dhaka rive nyore kuburitsa gasi rakaputirwa mariri, uye marara anokurumidza kuraswa mugomba rematope.

(3) Kuchera madhaka uye mamwe akamiswa kuparadzira samples ane humwe hupenyu hwese, hunogona kudzikamiswa nekuwedzerwa nekuwedzera CMC.

(4) Madhaka ane CMC haanyanyi kukanganiswa nekuumbwa uye saka haafanire kuchengetedza yakakwira PH kana kushandisa zvinodzivirira.

(5) Iine CMC sekuchera madhaka yekuchenesa fluid kurapwa mumiririri, inogona kuramba kusvibiswa kweakasiyana soluble munyu.

Madhaka ane CMC ane kugadzikana kwakanaka uye anogona kuderedza kurasikirwa kwemvura kunyangwe tembiricha iri pamusoro pe150°C.

Cherechedza: iyo CMC ine viscosity yakakwirira uye yakakwirira dhigirii yekutsiva inokodzera madhaka ane yakaderera density, nepo CMC ine yakaderera viscosity uye yakakwirira dhigirii yekutsiva inokodzera dhaka nehupamhi hwepamusoro. CMC inofanira kusarudzwa maererano nemamiriro akasiyana-siyana akadai semhando yematope, nharaunda uye kudzika kwetsime.

Kunyanya kushandiswa: CMC mukuchera mvura, simende fluid uye fracturing fluid, kusimudza viscosity uye mamwe mabasa, kuitira kuti uwane. Kuchengetedza madziro, takura zvicherwa zvekuchera, chengetedza zvishoma, kudzivirira kurasikirwa nedhaka, kunatsiridza basa rekuchera kumhanya. Wedzera zvakananga kana neglue kuti uwedzere dhaka, wedzera 0.1-0.3% mumatope emvura yakachena, wedzera 0.5-0.8% mumatope emvura yemunyu.

Inogona kukurumidza uye zvinogadzirisa kugadzirisa rheological maitiro emhando iyi yekuchera mvura. Iyo haina chete yakanaka yekusefa kurasikirwa maitiro, asi zvakare ine yakanakisa kugona kuchenesa makucheka uye drill bits.

Iyo polymer yekuchera mvura ine CMC inoenderana nemamwe mapolymer, ine simba rekumisa yakasimba, uye inogona kuchenesa kucheka panguva uye inobudirira. Pamusoro pezvo, mvura yekuchera zvakare yakanakisa kurasikirwa kwemvura mumiriri ine yakaderera solids uye ivhu kupararira.

Yakadzika yakasimba yekuchera mvura ine CMC inogona kukurumidza uye nemazvo kugadzirisa rheological zvimiro zvechibhorani, kugona kumiswa, panguva uye nekugona kubvisa kucheka, kuchengetedza mvura yekuchera ine yakaderera yakasimba, kunatsiridza kumhanya kwekuchera, kudzikamisa madziro echibhorani, uye kuve neakanakisa mvura. kurasikirwa kwekuita kuderedza.

Mvura yekuchera ine hushamwari kwezvakatipoteredza ine CMC ine hushamwari kwezvakatipoteredza, haina chepfu, haina kukuvadza uye haina kunhuhwirira, biodegradable uye haisi nyore kukanganisa panguva yekushandiswa. Mvura yekuchera ine mutengo wakaderera wekugadzirisa uye hutano nekuchengetedzeka kwevashandi vekuvaka kunovimbiswa. Yakakodzera kuchera pasi pezvakasiyana-siyana zvakaoma geological mamiriro uye isingakuvadzi kune kugadzirwa kwekurima.

2. Kushandiswa kwe sodium carboxymethyl cellulose CMC mu simenti fluid (kupedzisa fluid)

Cementing fluid kuyerera inovandudzwa neCEMenting slurry yakagadziridzwa neCMC, ichipa yakakwana yekutanga viscosity uye yakaderera mvura kurasikirwa, uku ichidzivirira tsime uye kudzivirira mvura kupinda mumapores uye kuputsika.

Iwo anotakura ane CMC anogona kugadzirisa fluidity yemvura, thixotropy uye kugona kumisa chikamu chakasimba. Nekuti zvigadzirwa zvine munyu wakanaka wekuramba (kunyanya monovalent metal ions), zvigadzirwa zvinogona kushandiswa kuchenesa mvura yemunyu packer zvinobudirira.

Iyo workover fluid inogadzirwa neCMC yekambani yakaderera-yakasimba uye haivharidzi kupenya kwenzvimbo yekugadzira nekuda kwezvakaoma kana kukuvadza nzvimbo yekugadzira. Uye ine kurasikirwa kwemvura yakaderera, kuitira kuti mvura muchikamu chekugadzira ideredzwe, uye mvura ichavharwa ne emulsion uye inoita mvura inobata chiitiko. Iyo workover fluid yakaumbwa neCMC nePAC inopa zvakanakira pamusoro peimwe workover fluid. Chengetedza nzvimbo yekugadzira kubva mukukuvadzwa zvachose; Cleanhole portability uye kuderedzwa kwechibhorani chekuchengetedza; Inopesana nekupinzwa kwemvura uye silt, uye haiwanzo kuputika; Inogona kuchengetwa kana kushandiswazve kubva patsime kuenda kune zvakanaka nemutengo wakaderera pane yakajairwa mud workover fluid.

3. Kushandiswa kwe carboxymethyl cellulose sodium CMC mu fracturing fluid

Yakagadzirirwa neCMC fracturing fluid, inogona kukurumidza kuvandudza viscosity ye fracturing fluid, inogona kutakura proppant mugomba remafuta kuputsika, kumisikidza nzira dzekuyerera, nekukasira kuderedza kuwanda kwekusefa, kumanikidza kwekugadzira kusimuka nekukurumidza, uye kuwana kufambisa kwakanaka kwekumanikidza. chigadzirwa hachina zvakasara, hapana kukuvadzwa kune yepasi, pumpability yakakwirira, diki friction, uye kugona kutakura proppant.

Kurongedza, kuchengetedza uye kutakura:

Zvigadzirwa zvacho zvakazara mumabhegi-epurasitiki akaumbwa masaga kana akaiswa mabhegi epurasitiki akarukwa uye akavharwa zvakasimba. Huremu hweNet 25kg pabhegi. Ichi chigadzirwa chinofanira kuchengetwa munzvimbo inotonhorera

Nzvimbo yakaoma, mukuchengetedza uye yekufambisa inofanirwa kudzivirira hunyoro, kupisa uye kukanganisa kwekutakura.
