Kushandiswa kweCMC muPetroleum

Petroleum giredhi CMC modhi: PAC- HV PAC- LV PAC-L PAC-R PAC-RECMC- HVCMC- LV

1. Mabasa ePAC neCMC munzvimbo yemafuta ndeaya anotevera:

1. Madhaka ane PAC neCMC anogona kuita kuti madziro etsime aite mutete uye akasimba sefa keke ine yakaderera permeability, kuderedza kurasikirwa kwemvura;

2. Mushure mekuwedzera PAC neCMC kumatope, chigadziro chekuchera chinogona kuwana simba rekutanga rekuveura rakaderera, kuitira kuti dhaka rive nyore kusunungura gasi rakaputirwa mairi, uye panguva imwe chete, tsvina inokurumidza kuraswa mumatope. gomba;

3. Kuchera madhaka, semamwe kumiswa uye kupararira, kune humwe hupenyu hwesherufu. Kuwedzera PAC neCMC kunogona kuita kuti igadzikane uye kurebesa hupenyu hwesherufu.

2. PAC neCMC vane zvinotevera zvakanakisa zvivakwa muoilfield application:

1. High degree of substitution, good uniformity of substitution, high viscosity, low dosage, zvinobudirira kuvandudza kushanda kwedhaka kushandiswa;

2. Kusagadzikana kwakanaka kwemvura, munyu kuramba uye alkali kuramba, yakakodzera mvura yakachena, mvura yegungwa uye yakazara mvura yemunyu-based matope;

3. Unhu hwekeke yakaumbwa yedhaka yakanaka uye yakagadzikana, iyo inogona kunyatsogadzirisa chimiro chevhu rakapfava uye kudzivirira rusvingo rwetsime kubva pakuputsika;

4. Inokodzera hurongwa hwematope ayo ane zvinyorwa zvakasimba zvakaoma kudzora uye ane huwandu hwakawanda hwekuchinja.

3. Maitiro ekushandisa eCMC nePAC mukuchera oiri:

1. Iine simba rakakwirira rekudzora kurasikirwa kwemvura, kunyanya kuderera kwepamusoro-kuderedza kurasikirwa kwemvura, iyo inogona kudzora kurasikirwa kwemvura pamwero wepamusoro pamwero wakaderera pasina kukanganisa mamwe maitiro ematope;

2. Good tembiricha kuramba uye zvakanakisa munyu kuramba. Pasi peimwe munyu, inogona kuramba iine hunyanzvi hwekudzikisa kurasikirwa kwemvura uye imwe rheology. Mushure mekunyungudutswa mumvura ine munyu, viscosity inenge isina kuchinjwa, kunyanya yakakodzera kushandiswa kwemahombekombe. Kuchera uye kudzika kwetsime zvinodiwa;

3. Inogona kudzora zvakanaka rheology yedhaka, ine thixotropy yakanaka, uye inokodzera chero madhaka emvura mumvura yakachena, mvura yegungwa, uye yakanyungudutswa yemunyu;

4. Mukuwedzera, PAC inoshandiswa sesementing fluid, iyo inogona kudzivirira mvura kuti isapinda pores uye kuputsika;

5. Iyo filtrate yakagadzirwa nePAC inogona kumira 2% KCL mhinduro (inofanira kuwedzerwa pakugadzirisa filtrate) uye ine yakanaka solubility, nyore kushandisa, inogona kugadzirirwa panzvimbo, uye ine kukurumidza kukurumidza gelation uye simba rakasimba rekutakura jecha. Inoshandiswa mukugadzira, uye kudzvanywa kwayo kusefa maitiro kwakanyanya kunaka.
