Daim ntawv thov
Acidification yog ib qho kev hloov pauv ntawm lub pas dej ua tau zoo rau kev tsim cov qhov dej thiab nce qhov dej. Lub hauv paus ntsiab lus yog txhaj cov kua qaub rau hauv lub qhov dej hauv qab lub pob zeb tawg, thiab cov kua qaub yog nyem rau hauv qhov pore qhov chaw nyob ze ntawm -wellbore. Los ntawm kev sib cais thiab kev sib cais ntawm cov kua qaub rau ntawm cov pob zeb cements los yog tsim cov pores, ntsaws rau hauv cov kab nrib pleb, thiab lwm yam, cov pob zeb hauv cov kua qaub intrusion txoj siv tau ua tiav tiav, tsim cov channel uas pab cov seepage ntawm cov roj thiab dej thiab rov qab permeability ntawm kev tsim. Cov txheej txheem cov kua qaub feem ntau yog hydrochloric acid lossis av acid + acidification corrosion inhibitor + hlau ion stabilizer + kua dej + av nplaum stabilizer + anti- mis nyuj - demulsifier + anti- sludge tus neeg saib xyuas, thaum siv cov pa acid qhov tob rau acidification, Cov tshuaj tiv thaiv ntawm cov kua qaub qhov system thiab cov txheej txheem ceev ceev ntawm cov kua qaub, qhov kev txiav txim siab luv luv ntawm cov kua qaub thiab cov pob zeb ua kom ceev ceev yog cov kua qaub. yog me me, feem ntau tsis ua tiav lub hom phiaj npaj. Kev qeeb cov tshuaj tiv thaiv ntawm cov kua qaub thiab qhov tsim yog qhov teeb meem tseem ceeb rau kev nce lub vojvoog ntawm
acid kho thiab txhim kho cov nyhuv acidification. Ua kom cov viscosity ntawm cov kua qaub tuaj yeem txo qis cov kua dej thiab ua kom qeeb ntawm cov dej num ntawm hydrogen ions. Nws yog qhov zoo tshaj plaws
retarding txoj kev thiab yog txoj kev zoo tshaj plaws los daws cov carbonate reservoirs hauv tsev thiab txawv teb chaws.
Thickening acid system
Lub thickened acid system yog ib tug 2% cationic emulsion polymer thickener ntxiv rau ib tug pa system. Tom qab ntxiv 2% cationic emulsion polymer thickener, tus nqi ib tuj ntawm acid tov system yog nce li ntawm 500 yuan / t piv nrog cov pa acid tov system. Txawm li cas los xij, hauv kev ua haujlwm acidification, tib cov kua qaub yog siv los siv tib yam. Lub vojvoog kho cov kua qaub ntawm lub thickened acid system tuaj yeem nce ntau zaus piv rau cov kua qaub kho lub vojvoog ntawm cov pa acid kua system, thiab thaj chaw kho cov kua qaub tuaj yeem nce ntau dua kaum npaug.
Lub thickening acid system yog cov tshuaj polymer acid, muaj cov viscosity ntau dua, thiab muaj cov txiaj ntsig hauv qab no piv nrog cov kua qaub kua qaub:
1. Cov pob zeb acid muaj cov tshuaj tiv thaiv qis, ua kom lub sijhawm tawg ntawm cov kua qaub hauv qhov tsim, thiab ua kom cov acidity nce ntxiv. Ua haujlwm nrug;
2, Tsawg tus nqi ntawm cov kua qaub pom, tus nqi siab ntawm kev siv cov kua qaub;
3, Tsis tshua muaj kev sib txhuam ntawm cov kav dej;
4, Shear tsis kam, zoo stability ntawm kub kub;
5, Degradation tsis tsim teeb meem residues;
6, Thickening acid Lub kaw lus tuaj yeem siv tsis tau tsuas yog rau matrix acidification tab sis kuj rau kev tsim cov kua qaub.
Kev ntsuam xyuas sab hauv tsev ntawm thickening acid system
Raws li tus qauv SY/T6214-1996 "acid thickener evaluation method" ntawm lub thickening acid system ua ib qho kev ntsuam xyuas sab hauv tsev:
1, Thickener acid dissolution lub sij hawm
Lub thickener yog thawj zaug ntxiv rau 20% hydrochloric acid nyob rau hauv 2% increments thiab muab tso rau hauv ib tug tig viscometer nruas ntawm chav tsev kub kom nplawm thiab yaj (170s-1). Lub viscosity ntawm cov kua qaub tau ntsuas ntawm lub sijhawm sib txawv kom txog thaum lub viscosity ntawm cov kua qaub ruaj khov. , sau lub sijhawm tsawg kawg nkaus thaum cov kua qaub viscosity ruaj khov.
| Sijhawm (min) | Viscosity (mPa.s) |
| 0 | 3.6 |
| 5 | 27.4 |
| 10 | 41.3 |

| 40 | 57.1 |
Raws li cov ntaub ntawv nyob rau hauv cov lus saum toj no, cov thickening tus neeg sawv cev muaj zoo dispersibility nyob rau hauv cov kua qaub, thiab viscosity ntawm cov kua qaub kua qaub nce sai sai tom qab cov thickening tus neeg sawv cev ntxiv rau cov kua qaub. Tom qab li 35 feeb, lub viscosity ntawm cov kua qaub yuav tsum ruaj khov, qhia tias cov thickener tau yaj tag nrho hauv cov kua qaub. Qhov ceev - solubility ntawm cov thickener pab kom luv cov kua qaub
Cov sijhawm ua haujlwm.
2, Thickness acid system thermal stability
Cov txheej txheem thickened acid tau rhuab mus rau 30℃thiab tom qab ntawd khaws cia ntawm qhov kub thiab txias rau 5 feeb. Lub viscosity ntawm thickened acid yog ntsuas ntawm 170 s-1. Tom qab ntawd lub thickened acid system tau muab tso rau hauv 500 mL hub nrog condensing device thiab rhuab mus rau 60 degree, tshem tawm tom qab qhov kub thiab txias 240min, ntuj txias rau 30℃C, sim cov viscosity ntawm cov kua qaub.
170s-1:
| 30℃viscosity (mPa.s) | Viscosity (mPa.s) tom qab qhov kub thiab txias ntawm 90℃rau 4 teev | Thermal stability (%) |
| 57.1 | 35.9 | 62.5 |
Lub viscous acid system tuaj yeem tswj tau nws cov viscosity ntawm 35.9 mPa.s tom qab cua sov ntawm 90℃rau 240 feeb. Nws muaj qhov zoo thermal stability, uas yog qhov tsim nyog rau kev ua tiav ntawm acidification kev tsim kho.
3, Thickening acid system shear stability
Lub thickened acid system yog thermostated ntawm 30℃thiab tsis tu ncua sheared nrog ib tug viscometer rotational ntawm qhov kub no. Lub shear tus nqi yog 170 s-1 thiab lub sij hawm tsis tu ncua yog 120 feeb. Cov ntaub ntawv txhua xyoo ntawm cov kua qaub tau sau tseg txhua 20 feeb:
| Lub sijhawm txiav (min) | Viscosity (mPa.s) |
| 0 | 57.2 |
| 20 | 56.7 |
| 40 | 56.1 |
| 60 | 55.3 |
| 80 | 54.5 |
| 100 | 53.8 |
| 120 | 53.1 |
Lub kaw lus kua qaub tseem tuaj yeem tuav nws cov viscosity ntawm 53.1 mPa.s tom qab 120min nruam shearing, qhia tau hais tias cov thickened acid system muaj zoo shear stability.
4, Kev ua haujlwm qeeb qeeb ntawm thickened acid system
Configure cov pa acid system thiab cov thickening acid system feem nyob rau hauv ib tug 500-mL wide- lub qhov ncauj lub raj mis. Ntxiv 4 × 2 × 2 cm marble thaiv nyob rau hauv qhov tsis tu ncua - da dej kub ntawm 90 ° C. rau 30 feeb thiab sau lub sijhawm pib. Tsis muaj npuas nyob hauv cov kua qaub. Kev khiav tawm rau lub sijhawm txiav tawm, raws li cov qauv R=(t'-t1) / (t'2-t2) suav cov kua qaub thickening ncua sij hawm ntau:
|
Lub sij hawm teb nrog marble block(s)
|
|
| Pa acid system | 683 |
| Thickening acid system | 1972 |
Raws li cov qauv saum toj no, lub sij hawm polycondensation ntawm lub thickened acid system yog 2.887 lub sij hawm, uas qhia tau hais tias lub thickened acid system muaj kev ua tau zoo qeeb - ceev. Nyob rau hauv daim ntawv thov daim teb, lub thickened acid system tuaj yeem ua rau kom cov acidification txoj kev kho lub vojvoog piv rau cov pa acid systems.
