CMC ikoresha munganda za peteroli na peteroli

Sodium carboxymethyl selulose (CMC) ikozwe muri selile karemano muguhindura imiti ikomoka kumazi ya elegitoronike ya selile yamashanyarazi, ni ubwoko bwingenzi bwamazi ya elegitoronike ya eferi, ifu yera cyangwa umuhondo cyangwa ifu ya granular, idafite uburozi, uburyohe, irashobora gushonga mumazi, ifite ubushyuhe bwiza hamwe no kurwanya umunyu, imiti ikomeye ya mikorobe. Amazi meza yateguwe niki gicuruzwa afite gutakaza amazi meza, kubuza no kurwanya ubushyuhe bwinshi. Ikoreshwa cyane mu nganda zicukura peteroli, cyane cyane amazi yumunyu Iriba no gucukura amavuta yo hanze.

Sodium carboxymethyl selulose CMC nka polymer ibora amazi, irashobora gushonga vuba mumazi akonje cyangwa mumazi ashyushye; Nkumubyimba, imiti igenzura rheologiya, ifata, stabilisateur, irinda colloid, agent ihagarika hamwe nogukoresha amazi, nikintu cyiza cyo gutunganya ibyondo no gutegura ibikoresho byamazi byuzuye mugikorwa cyo gucukura amavuta. Ifite umuvuduko mwinshi hamwe no kurwanya umunyu mwiza. CMC ni igihombo cyiza cyo kugabanya amazi meza yicyondo cyamazi nicyondo cyamazi cyuzuyemo umunyu wumunyu, kandi ufite ubushobozi bwo guterura ibibyimba no kurwanya ubushyuhe bwinshi (150℃). Bikwiranye nogutegura amazi meza, yinyanja hamwe nuzuye yuzuye ya brine yuzuye, hamwe nuburemere bwa calcium chloride irashobora gutegurwa mubwinshi butandukanye bwamazi yuzuye, hamwe nubwuzuzanye bwamazi yuzuye hamwe no gutakaza amazi make.

Intangiriro yaCMC HV naCMC LV kumavuta yo gucukura peteroli

(1) Icyondo cya CMC kirashobora gutuma urukuta rwiriba ruba ruto kandi rukomeye rwo kuyungurura kandi rufite imbaraga nke, kugirango bigabanye gutakaza amazi.

(2)Nyuma yo kongeramo CMC mubyondo, imyitozo irashobora kubona imbaraga zambere zo kogosha, kuburyo icyondo cyoroshye kurekura gaze yizingiyemo, kandi imyanda ikajugunywa vuba mumwobo wibyondo.

.

(4) Ibyondo birimo CMC ntibibasiwe cyane nububiko bityo ntibikeneye gukomeza PH ndende cyangwa gukoresha imiti igabanya ubukana.

.

Icyondo kirimo CMC gifite ituze ryiza kandi kirashobora kugabanya gutakaza amazi nubwo ubushyuhe buri hejuru ya 150°C.

Icyitonderwa: CMC ifite ubukonje bwinshi kandi murwego rwo hejuru rwo gusimbuza ikwiranye nicyondo gifite ubucucike buke, mugihe CMC ifite ubukonje buke hamwe nubunini bwo gusimbuza ikwiranye nicyondo gifite ubucucike bwinshi. CMC igomba gutoranywa ukurikije ibihe bitandukanye nkubwoko bwibyondo, akarere nuburebure bwimbitse.

Ibyingenzi bikoreshwa: CMC mugucukura amazi, sima ya sima no kuvunika amazi, guterura ububobere nibindi bikorwa, kugirango ubigereho. Kurinda urukuta, gutwara ibiti byo gucukura, kurinda bito, kwirinda gutakaza ibyondo, kunoza uruhare rwumuvuduko. Ongeramo mu buryo butaziguye cyangwa hamwe na kole kugirango wongere ibyondo, ongeramo 0.1-0.3% mubyondo byamazi meza, ongeramo 0.5-0.8% mubyondo byamazi yumunyu.

Ibiranga ibicuruzwa:

.

Uburyo bwo gutemba. Ifite ibyiza byo guhagarika ikwirakwizwa rya shale, kurwanya ihumana rya ion organique, kugabanya igihombo cyamazi, kongera umuvuduko wogucukura no kugabanya ibiciro.

2.Nkugenzura uburyo bwo gutembera kumazi, ibicuruzwa bifite umwaka utandukanye, imikorere yo kugabanya igihombo hamwe nibikorwa byo guhindura imikorere kandi nibyiza

Irashobora gukoreshwa nkubwiyongere bwiyongera no kuyungurura bigabanya mumazi meza hamwe namazi yumunyu.

1. Ifite umwanda mwiza no kurwanya ubushyuhe.

Gukoresha sodium carboxymethyl selulose CMC mubikorwa byo gucukura peteroli

1. Gukoresha sodium carboxymethyl selulose CMC mumazi yo gucukura

Amazi adashobora gukwirakwizwa afite ibikoresho bya CMC afite ibiti bikomeye bitwara ubushobozi, bikabuza gutatanya ibumba, bigabanya umuvuduko w’ibumba, bigira akamaro mu gutuza neza kandi byongera umuvuduko wo gucukura.

Amazi yataburuwe hamwe na CMC afite ubushobozi bwiza bwo guhagarikwa, arashobora kwakira icyiciro gikomeye, arashobora guteza imbere cyane ihindagurika ryimyanya ndangagitsina, nicyo kibereye cyane amazi yo gucukura cyane, kandi arashobora guhindura neza imiterere ya rheologiya yamazi yo gucukura; Cake yuzuye kandi yujuje ubuziranenge irashobora gukorwa mumazi yo gucukura, ifite igabanuka ryiza rya filteri no kugabanya amazi kubuntu.

Kalisiyumu ivura amazi yo gucukura hamwe na CMC ifite imbaraga zo kurwanya calcium kandi irashobora gukumira ihindagurika ryinshi ryibumba ryibumba muri sisitemu yatewe na calcium ion, kugirango amazi yo gucukura ashobore kugumana imiterere myiza y’ibimera kandi bigumane ibintu bihamye hamwe n’imiterere y’imiterere y’amazi yo gucukura, kugirango tumenye neza imikorere ihamye ya dring.

Hamwe na CMC igizwe na brine, amazi yo mumazi yo mumazi yo mumazi, gutobora amazi yuzuye amazi yumunyu wamazi, kutumva neza umunyu, kurwanya umunyu na calcium, magnesium, bikoreshwa nkumuteguro wa rheologiya, bitewe na dosiye nkeya yo gucukura amazi ya rheologiya byihuse Guhindura, birashobora gukora vuba gutema icyarimwe, kugumana ibintu bikomeye, bifasha kunoza umuvuduko. Iyo ikoreshejwe nkigabanya igihombo cyamazi, cake yuzuye ibyondo irashobora gushirwaho. Nkuko akayunguruzo kayungurujwe kayunguruzo kegereye hafi yo gushiraho amazi yibanze, akayunguruzo ntikangirika cyane kuri peteroli na gaze.

Amazi yo gucukura ashingiye kuri potasiyumu afite ibikoresho bya CMC afite ubushake buke ku myunyu ya potasiyumu, umunyu wa calcium n'umunyu wa magnesium. Irashobora kwihuta kandi neza guhindura imiterere ya rheologiya yubwoko bwamazi yo gucukura. Ntabwo ifite ingaruka nziza zo kuyungurura gusa, ahubwo ifite n'ubushobozi buhebuje bwo guhanagura ibiti no gucukura ibice.

Amazi yo gucukura ya polymer afite ibikoresho bya CMC arahuza nizindi polymers, afite ubushobozi bukomeye bwo guhagarika, kandi ashobora guhanagura ibiti mugihe kandi neza. Byongeye kandi, amazi yo gutobora nayo ni ikintu cyiza cyo gutakaza amazi afite ibintu bike kandi bikwirakwiza ibumba.

Amazi make yo gucukura afite ibikoresho bya CMC arashobora guhindura byihuse kandi neza imiterere ya rheologiya yamazi yo gucukura, ubushobozi buhebuje bwo guhagarika, kuvanaho igihe kandi neza, kugabanya amazi yo gucukura afite ibintu bike, kunoza umuvuduko wo gucukura, guhagarika urukuta rwa boreho, kandi bifite amazi meza ingaruka zo kugabanya igihombo.

Amazi yo gucukura yangiza ibidukikije afite ibikoresho bya CMC yangiza ibidukikije, ntabwo ari uburozi, atagira ingaruka kandi nta mpumuro nziza, ibinyabuzima bishobora kwangirika kandi ntibyoroshye kwangirika mugihe cyo kuyikoresha. Amazi yo gucukura afite amafaranga make yo kubungabunga kandi ubuzima n’umutekano byabakozi bashinzwe ubwubatsi biremewe. Irakwiriye gucukurwa mubihe bitandukanye bya geologiya kandi bitangiza umusaruro wubuhinzi.

2. Gukoresha sodium carboxymethyl selulose CMC mumazi ya sima (amazi yuzuye)

Amazi ya sima yatunganijwe neza hamwe na CEMenting slurry yagizwe na CMC, itanga ubwiza bwambere bwambere hamwe no gutakaza amazi make, mugihe urinda iriba no kubuza amazi kwinjira mumyenge no kuvunika.

Abapakira bafite ibikoresho bya CMC barashobora guhindura amazi, thixotropy hamwe nubushobozi bwo guhagarika icyiciro gikomeye. Kuberako ibicuruzwa bifite imbaraga zo kurwanya umunyu (cyane cyane ioni monovalent), ibicuruzwa birashobora gukoreshwa mugusukura amazi yumunyu neza.

Amazi yo gukora yateguwe hamwe na CMC yisosiyete arakomeye kandi ntabuza ubwikorezi bwakarere gatanga umusaruro kubera ibinini cyangwa byangiza akarere. Kandi ifite igihombo gito cyamazi, kuburyo amazi yinjira murwego rwo kubyaza umusaruro agabanuka, kandi amazi azahagarikwa na emulsiyo hanyuma agire ikintu gifata amazi. Amazi yo gukora yakozwe na CMC na PAC atanga inyungu kurenza andi mazi akora. Kurinda agace k’umusaruro kwangirika burundu; Isuku yikwirakwizwa no kugabanya gufata neza imyobo; Irwanya kwinjiza amazi na sili, kandi ni gake cyane; Irashobora kubikwa cyangwa gukoreshwa kuva iriba kugeza neza ku giciro gito ugereranije n'amazi asanzwe akora.

3. Gukoresha carboxymethyl selulose sodium CMC mumazi yamenetse

Iteguwe na CMC yamenetse, irashobora kwihutisha ubwiza bwamazi yamenetse, irashobora gutwara neza proppant mumavunika yamariba, gushiraho imiyoboro yinyanja, kugabanya vuba ubwinshi bwayunguruzo, umuvuduko wubwiyongere bwihuse, kandi kugirango ugere kumyuka neza, ibicuruzwa ntibisigara, nta byangiritse kubyihishe inyuma, pompability iri hejuru, guterana duto, kandi bifite ubushobozi bwo gutwara proppant.

Gupakira, kubika no gutwara:

Ibicuruzwa bipakiye mumifuka yububiko bwa pulasitike cyangwa imifuka ikozwe mumashanyarazi kandi bifunze neza. Uburemere bwa 25 kg kumufuka. Ibicuruzwa bigomba kubikwa ahantu hakonje

Ahantu humye, mububiko no gutwara abantu hagomba gukumira ubushuhe, ubushyuhe no gupakira.
