FC-FR220S Fluid loss Control zowonjezera
The fluid loss control sulphonate copolymer (kubowola madzi) FC-FR220S itengera lingaliro la kapangidwe ka maselo kuti apititse patsogolo kulimba kwa molekyulu ya copolymer.The anayambitsa monoma kubwereza wagawo ali lalikulu danga voliyumu, amene angathe mogwira kuonjezera wosabala chotchinga ndi kusintha zotsatira za mankhwala pa kulamulira HTHP kutaya madzimadzi;Pa nthawi yomweyo, mphamvu yake kukana kutentha ndi mchere kashiamu ndi zina kumatheka kudzera kukhathamiritsa kwa kutentha ndi mchere kulolera monomers.Izi zimagonjetsa zofooka za kuwongolera kowonongeka kwamadzimadzi a polima, monga kusamva bwino kwa kukameta ubweya, kusamva bwino kwa calcium yamchere, ndi zotsatira zosakhutiritsa zowongolera kutayika kwamadzi a HTHP.Ndi njira yatsopano yowongolera polima yamadzimadzi.
| Kanthu | Mlozera | Deta yoyezedwa | |
| Maonekedwe | ufa woyera kapena wachikasu | White ufa | |
| Madzi, % | ≤10.0 | 8.0 | |
| Sieve zotsalira(sieve pore 0.90mm), % | ≤10.0 | 1.5 | |
| pH mtengo | 7.0～9.0 | 8 | |
| 30% saline slurry atakalamba pa 200 ℃/16h. | Kutayika kwamadzi a API, ml | ≤5.0 | 2.2 |
| Kutaya madzimadzi a HTHP, ml | ≤20.0 | 13.0 | |
1. FC-FR220S ili ndi kukana kwambiri mchere.Kupyolera mu kuyesa m'nyumba, sinthani mchere wamadzimadzi obowola omwe amagwiritsidwa ntchito poyesa kufufuza kukana kwa mchere wa FC-FR220S mankhwala atakalamba pa 200 ℃ m'matope apansi okhala ndi mchere wosiyanasiyana.Zotsatira zoyeserera zikuwonetsedwa mu Chithunzi 1:
Ndemanga: Mapangidwe a base slurry kuti awonedwe: 6% w/v nthaka ya sodium + 4% w/v yowunikira nthaka + 1.5% v/v alkali solution (40% concentration);
Kutayika kwamadzimadzi kwa HTHP kudzayesedwa pa 150 ℃ pa 3.5MPa.
Zitha kuwoneka kuchokera ku zotsatira zoyesera mu Chithunzi 1 kuti FC-FR220S ili ndi ntchito yabwino kwambiri poyang'anira kutaya kwa madzi a HTHP pansi pa mchere wosiyanasiyana, ndipo imakhala ndi ntchito yokhazikika komanso kukana mchere wabwino kwambiri.
2. FC-FR220S ili ndi kukhazikika kwabwino kwamafuta.Kuyesera kwamkati kumachitidwa kuti afufuze malire a kutentha kwa FC-FR220S mu 30% brine slurry powonjezera pang'onopang'ono kutentha kwa ukalamba wa FC-FR220S.Zotsatira zoyeserera zikuwonetsedwa mu Chithunzi 2:
Ndemanga: Kutayika kwamadzimadzi kwa HTHP kumayesedwa pa 150 ℃ ndi 3.5MPa.
Zitha kuwoneka kuchokera pazotsatira zoyeserera mu Chithunzi 2 kuti FC-FR220S ikadali ndi gawo labwino pakuwongolera kutaya kwamadzimadzi a HTHP pa 220 ℃ ndi kuchuluka kwa kutentha, ndipo ili ndi kukana kutentha kwambiri ndipo ingagwiritsidwe ntchito pachitsime chakuya komanso chozama kwambiri. kubowola.Deta yoyesera ikuwonetsanso kuti FC-FR220S ili ndi chiwopsezo cha kutentha kwapamwamba kwambiri pa 240 ℃, kotero sikovomerezeka kuigwiritsa ntchito kutentha uku kapena kupitilira apo.
3. FC-FR220S ili ndi kuyanjana kwabwino.Kuchita kwa FC-FR220S atakalamba pa 200 ℃ m'madzi a m'nyanja, brine pawiri ndi ma saturated brine pobowola kachitidwe kamadzimadzi amafufuzidwa kudzera mu kuyesa kwa labotale.Zotsatira zoyeserera zikuwonetsedwa mu Gulu 2:
Table 2 Kuwunika Kwantchito Zotsatira za FC-FR220S mu Different Drilling Fluid Systems
| Kanthu | AV mPa.s | FL API ml | FL HTHP ml | Ndemanga |
| Madzi a m'nyanja pobowola madzimadzi | 59 | 4.0 | 12.4 | |
| Compound brine pobowola madzimadzi | 38 | 4.8 | 24 | |
| Amadzaza brine pobowola madzimadzi | 28 | 3.8 | 22 |
Zitha kuwoneka kuchokera pazotsatira zoyeserera mu Table 2 kuti FC-FR220S imayenderana bwino ndipo ndi njira yabwino kwambiri yowongolera kutaya kwamadzimadzi powongolera kutayika kwamadzimadzi a HTHP kumakina obowola monga madzi am'nyanja, brine pawiri ndi saturated brine, ndi zina zambiri.
