1. Xaiv cov av nkos
(1) Av nplaum: Siv cov kev xav tau zoo bentonite, thiab nws cov kev xav tau muaj raws li nram no: 1. Pictle loj: ua rau 200 mesh. 2. Cov ntsiab lus noo: Tsis pub ntau tshaj 10% 3. Pulping tus nqi: Tsis pub tsawg tshaj 10M3 / Nyhav. 4. Dej Poob: Tsis ntau tshaj 20mL / min.
(2) Xaiv Dej: Cov dej yuav tsum tau kuaj rau cov dej tsis zoo. Feem ntau, cov dej muag muag yuav tsum tsis pub tshaj 15 degrees. Yog tias nws tshaj, nws yuav tsum tau softened.
(3) Hydrolyzed Polyacrylamide: Qhov kev xaiv ntawm hydrolyzed polyacrylamide yuav tsum yog hmoov av tsis tsawg tshaj li 5 lab thiab ib qib ntawm cov hydrolysis ntawm 30%.
(4) Hydrolyzed Polyacrylonitrile: Kev xaiv ntawm hydrolyzed polyacrylonitrile yuav tsum qhuav hmoov 100,000-200,000, thiab degree ntawm hydrolysis 55-65%.
(5) Dej tshauv (naj npawb2Co3): Decalcify Bentonite txhawm rau txhim kho nws qhov kev ua tau zoo (6) poov tshuaj humate: hmoov dub yog qhov zoo tshaj plaws
2. Npaj thiab siv
(1) Cov khoom xyaw yooj yim hauv txhua cov av nkos: 1. Bentonite: 5% -8%, 50-80kg. 2. Dej tshauv (Naco3): 3% rau 5% ntawm cov av ntim, 1.5 txog 4kg ntawm dej qab zib tshauv. 3. Hydrolyzed Polyacrylamide: 0.015% rau 0.03%, 0.15 rau 0.3kg. 4. Hydrolyzed Polyacrylonitrile Qhuav Qhuav Hmoov: 0.2% txog 0.5%, 2 txog 5kg ntawm hydrolyzed polyacrylonitrile qhuav.
Tsis tas li ntawd, raws li qhov kev tsim cov xwm txheej tsim, ntxiv 0.5 txog 3 kg ntawm anti-slumping tus neeg sawv cev, tus neeg sawv cev dej thiab txo cov meter ntawm cov av nkos. Yog tias qhov kev txiav quas tau yooj yim rau kev vau thiab nthuav dav, ntxiv txog 1% los tiv thaiv tus neeg sawv cev thiab li 1% potassium humed.
(2) Cov txheej txheem npaj npaj: nyob rau hauv ib txwm muaj tshwm sim, txog 50m3 ntawm cov av uas xav tau los xyaum 1000m borehole. Kev npaj 20m3 av nkos ua piv txwv, txheej txheem npaj ntawm "Ob Chav Npaj Polymer Av" yog raws li hauv qab no:
1. Tso 30-80kg ntawm dej qab zib dej so 2. Ua ntej siv, ntxiv cov av nkos rau hauv dej kom huv kom nws ua rau 20m3 lub hauv paus slurry. 3. Dissolve 3-6kg ntawm hydrolyzed polyacrylamide cov hmoov nplej qhuav nrog dej thiab ntxiv rau hauv lub hauv paus slurry; Dilute thiab yaj 40-100kg ntawm hydrolyzed polyacrylonitrile qhuav hmoov nrog dej thiab ntxiv rau hauv paus slurry. 4. Do zoo tom qab ntxiv tag nrho cov khoom xyaw
(3) Kev sim ua ntau yam cuab yeej ntawm cov av nkos yuav tsum tau kuaj xyuas thiab txhua ntu yuav tsum ua tiav cov qauv hauv qab no: Tsawg dua 4%: Tsawg dua 1.06 funnel viscosity (t) : 17 txog 21 lub lim dej ntim dej (b): tsawg dua 15ml / 30 feeb mud khoom qab zib (k):
Cov khoom xyaw ntawm Drilling av nkos ib mais
1. Av nplaum:
Xaiv cov kev ua tau zoo bentonite, thiab nws cov kev xav tau muaj raws li nram no: 1. Cov ntsiab lus noo noo: Tsis pub dhau 10 m3 / tuj 4. Dej poob: Tsis muaj Ntau tshaj 20ml / min5. Kev: 3000 ~ 4000Kg

NAOH (Causic dej qab zib): 10kg. 5. Inert cov ntaub ntawv rau ntsaws (pom ua npuas dej, cottonses husk, thiab lwm yam): 250kg.
Kev sib xyaw ua haujlwm qis theem tiv thaiv kev sib tsoo av nkos
1. NTA
1. Cov kua zoo thiab muaj peev xwm nqa cov hmoov pob zeb. 2. Yooj yim mud kev kho mob, kev saib xyuas yooj yim, ruaj khov ua haujlwm thiab lub neej ntev. 3. Kev siv thoob plaws, nws tuaj yeem siv tsis tsuas yog nyob rau hauv xoob, tawg thiab collapsed strata, tab sis kuj nyob hauv av nkos tawg pob zeb thiab dej-rhiab pob zeb stratum. Nws tuaj yeem ua tau raws phab ntsa kev tiv thaiv cov cai ntawm txawv pob zeb.
4. Nws yog qhov yooj yim los npaj, tsis muaj cua sov lossis ua ntej ua ntej, tsuas yog sib tov ob theem qis theem slurries thiab do zoo. 5. Qhov no zoo ntawm kev cog lus hauv av nkos tsis tsuas yog tawm tsam kev poob qis ua haujlwm, tab sis kuj muaj txoj haujlwm ntawm kev tawm tsam.
2. Kev npaj ntawm kev sib xyaw ntawm cov av qeeg qis 2. Dej tshauv (naj npawb2CO3) 0.5%. 3. Sodium Carboxypotassium cellulose (NA-CMC) 0.4%. 4. Polyacrylamide (Pam molecular hnyav yog 12 lab chav nyob) 0.1%. 5. Cov poov tshuaj tshuaj chloride (KCl) 1%. Kua B: poov tshuaj humate (Khm) qis theem theem tiv thaiv av nkos
1. Bentonite 3%. 2. Dej tshauv (naj npawb2CO3) 0.5%. 3. Cov poov tshuaj humate (Khm) 2.0% rau 3.0%. 4. Polyacrylamide (Pam molecular hnyav yog 12 lab chav nyob) 0.1%. Thaum siv, sib tov cov npaj ua kua a thiab kua b ntawm ib lub ntim piv ntawm 1: 1 thiab do kom huv si.
3. Mechanism Kev Ntsuam Xyuas ntawm kev sib sau ua ke ntawm cov khib nyiab qis anti-slump thaiv kev tiv thaiv av
Ua kua a yog polyacrylamide (PAM) -potassium chloride (KCl) qis-khoom siv av nkos, uas yog cov av nkos zoo nrog kev ua kom poob qis. Cov nyhuv sib xyaw ua ke ntawm Pam thiab KCl tuaj yeem ua tau zoo rau cov hydration nthuav dav ntawm cov nyhuv dej, thiab muaj cov kev tiv thaiv zoo heev rau kev siv dej-rhiab. Nws zoo inhibits lub hydration nthuav dav ntawm hom pob zeb tsim no thaum lub sij hawm tsim kev tsim dej yog nthuav tawm, yog tsis muaj kev sib tsoo ntawm lub qhov ntsa.
Cov kua mis B yog cov poov tshuaj humate (Khm) humed Khm yog cov neeg saib xyuas kev nyab xeeb zoo, uas tiv thaiv lub teeb meem phab ntsa, thiab tiv thaiv kom txhob quav hluav taws xob hauv cov cuab yeej drunting hauv cov cuab yeej drilling.
Ua ntej tshaj plaws, thaum ncig cov txheej txheem ntawm poov tshuaj humate (Khm) humidacle tsis muaj kev sib hloov hauv lub qhov, ntawm cov poov tshuaj yuav nkawm neeg thiab av nplaum hauv cov av nkos tuaj yeem pom Mus rau hauv qhov xoob thiab tawg pob zeb tsim nyob rau hauv kev txiav txim ntawm Centrifugal quab yuam. Qhov xoob thiab tawg pob zeb pob zeb ua lub luag haujlwm ntawm kev ua kom pom kev thiab tsis tiv thaiv kom noo thiab raus rau lub qhov ntsa thawj qhov chaw. Thib ob, qhov uas muaj qhov khoob thiab kev txom nyem hauv lub qhov av, av nplaum thiab kev nyuaj siab nyob rau hauv kev ua ntawm Centrifugal Dag, thiab tom qab ntawd lub qhov ntsa lub zog yuav muaj zog siv zog thiab kho. Thaum kawg, poov tshuaj humate (Khm) theem qis-tau los ua ib lub sijhawm, thiab tuaj yeem ua ib lub sijhawm me me, thiab tuaj yeem ua kom tawv nqaij, thiab cov av duens, uas txuas ntxiv tiv thaiv nws Tiv thaiv cov exaspage thiab yaig ntawm dej ntawm lub pore ntsa, thiab tib lub sijhawm ua lub luag haujlwm ntawm kev txhawb zog ntawm phab ntsa. Cov tawv ntoo av du cov nyhuv ntawm kev txo cov laum ntawm lub ntsuas phoo, tiv thaiv kev puas tsuaj rau lub qhov kev co los ntawm cov cuab yeej drilling vim tias muaj kev tawm tsam ntau dhau.
Thaum ua kua thiab ua kua b yog sib xyaw hauv tib lub zog sib xyaw ntawm 1: 1, ua kua rau hauv thawj zaug, thiab ua kua b tuaj yeem siv rau hauv Thawj thawj zaug nws ua lub luag haujlwm hauv kev lim ntshav thiab ua kom dawb huv ntawm "xoob thiab tawg" pob zeb. Raws li cov sib xyaw ua kua kab hauv lub qhov ntev, kua b yuav kawm tiav ntawm cov av hauv av, yog li maj mam ua lub luag haujlwm tseem ceeb ntawm kev tiv thaiv phab ntsa thiab tiv thaiv kev vau.
