IsticmaalkaCMC ee OilfieldWarshadaha

Carboxymethyl cellulose (CMC) waxaa si weyn loogu isticmaalaa warshadaha oilfield codsiyada kala duwan ay sabab u tahay sifooyinka gaarka ah iyo functionalities. Waxa ay u adeegtaa sidii wax-ku-darka badan ee dareeraha qodista, dareerayaasha dhamaystirka, iyo sibidhka sibidhka, iyo codsiyada kale. Waa kuwan qaar ka mid ah isticmaalka caanka ah ee CMC ee warshadaha saliidda:

1. Dheecaannada qodista:

• Viscosifier: CMC waxa loo isticmaalaa sida wakiilka galka ah ee dareerayaasha qodista biyaha ku salaysan si loo kordhiyo viscosifier iyo wanaajinta awoodda qaadista dareeraha. Waxay ka caawisaa ilaalinta xasiloonida ceelka, joojinta gooyn, iyo xakamaynta luminta dareeraha inta lagu jiro hawlgallada qodista.
• Xakamaynta Luminta Dheecaannada: CMC waxay u shaqeysaa sidii wakiilka xakamaynta luminta dareeraha iyadoo ku samaynaysa kee khafiif ah oo shaandhayn ah oo aan la nadiifin karin derbiga ceelka, ka hortagga dareeraha xad-dhaafka ah ee samaynta.
• Ka-hortagga Shale: CMC waxay ka caawisaa joojinta bararka iyo kala firdhisanaanta shaleemka iyadoo daboosha meelaha shaleeska ah iyo ka hortagga fuuq-baxa walxaha dhoobada ah, yaraynta khatarta xasillooni-darrada ceelka iyo shilalka tuubooyinka.
• Dejinta dhoobada: CMC waxay dejisaa macdanta dhoobada falcelisa ee dareeraha qodista, ka hortagga bararka dhoobada iyo guuritaanka, iyo hagaajinta waxtarka qodista ee qaababka hodanka ku ah dhoobada.

2. Dheecaannada Dhameystirka:

• Xakamaynta Luminta Dheecaannada: CMC waxaa lagu daraa dareerayaasha dhammaystirka ah si loo xakameeyo luminta dareeraha samaynta inta lagu jiro dhammaystirka wanaagsan iyo hawlgallada shaqada. Waxay ka caawisaa ilaalinta daacadnimada samaynta waxayna ka hortagtaa waxyeelada samaynta.
• Xasilinta Shale: CMC waxay gacan ka geysataa xasilinta shaleeska iyo ka hortagga fuuq-baxa dhogorta iyo bararka inta lagu jiro hawlgallada dhammaystirka, yaraynta xasilloonida ceelasha iyo hagaajinta wax soo saarka wanaagsan.
• Samaynta Keega Filter: CMC waxay kor u qaadaa samaynta labbis, keega filter aan la taaban karin ee wejiga samaynta, yaraynta cadaadiska kala duwan iyo u guuritaanka dareeraha ee samaynta.

3. Sibidhka Sibidhka:

• Dareeraha Luminta Dareemaha: CMC waxay u adeegtaa sida wax lagu daro dareeraha luminta dareeraha sibidhka si ay u yarayso luminta dareeraha qaab-dhismeedyada la dami karo oo loo hagaajiyo waxtarka meelaynta sibidhka. Waxay kaa caawinaysaa in la hubiyo go'doomin ku habboon aagga iyo isku xidhka sibidhka.
• Wakiilka Dhumucda: CMC waxa uu u shaqeeyaa sidii wakiilka dhumuc ee dareeraha sibidhka, isaga oo siinaya xakamaynta viscosity iyo kor u qaadida bamgareynta iyo joojinta walxaha sibidhka inta lagu jiro meelaynta.
• Wax ka beddelka Rheology: CMC waxay wax ka beddeshaa rheology ee dareeraha sibidhka, hagaajinta sifooyinka socodka, caabbinta sag, iyo xasilloonida xaaladaha hoos u dhaca.

4. Soo kabashada saliida la xoojiyey (EOR):

• Daadka Biyaha: CMC waxaa loo isticmaalaa hawlgallada fatahaadda biyaha si kor loogu qaado waxtarka xaaqida iyo horumarinta soo kabashada saliidda kaydadka. Waxay kordhisaa viscosity ee biyaha duritaanka, hagaajinta xakamaynta dhaqdhaqaaqa iyo waxtarka barakaca.
• Daadadka Polymer: Codsiyada daadka polymerka, CMC waxaa loo shaqeeyaa sidii wakiilka kontoroolka dhaqdhaqaaqa si uu u wanaajiyo waafaqsanaanta polymers-ka la duray oo uu kordhiyo waxtarka xaaqida ee daadinta dareerayaasha.

5. Dheecaannada Jajabka:

• Viscosifier dareere ah: CMC waxaa loo isticmaalaa sidii wakiilka galka ah ee dareeraha hydraulic jabinta si loo kordhiyo viscosity dareeraha iyo faafinta awoodda. Waxay ka caawisaa abuurista iyo ilaalinta jabka samaynta waxayna xoojisaa gaadiidka iyo meelaynta.
• Kobcinta Wanaajinta Jajabka: CMC waxay caawisaa ilaalinta hufnaanta xirmada proppant iyo hagaajinta jabka iyadoo hoos u dhigaysa dareeraha dareeraha ah ee samaynta iyo ka hortagga dejinta proppant.

Isku soo wada duuboocarboxymethyl cellulose(CMC) waxay door muhiim ah ka ciyaartaa codsiyo kala duwan oo ka dhex jira warshadaha saliida, oo ay ku jiraan dareerayaasha qodista, dareerayaasha dhamaystirka, dareeraha sibidhka, soo kabashada saliida ee la xoojiyey (EOR), iyo dareerayaasha dillaaca. Kala duwanaanshaheeda sida wakiilka xakamaynta luminta dareeraha, viscosifier, shale inhibitor, iyo reology modifier ayaa ka dhigaya wax lagu daro lagama maarmaanka u ah hubinta hawlo shidaal oo hufan oo guul leh.
