1. Kusarudzwa kwezvinhu zvevhu
(1) Clay: Shandisa bentonite yepamusoro-soro, uye zvido zvayo zvehutano ndezvizvi: 1. Particle size: pamusoro pe200 mesh.2. Hunyoro hunyoro: kwete kupfuura 10% 3. Pulping rate: kwete pasi pe10m3 / ton.4. Kurasikirwa kwemvura: kwete kupfuura 20ml / min.
(2) Kusarudzwa kwemvura: Mvura inofanira kuongororwa kuti ione sei mvura.Kazhinji, mvura yakapfava haifaniri kudarika 15 degrees.Kana yakapfuura, inofanira kunyoroveswa.
(3) Hydrolyzed polyacrylamide: Sarudzo ye hydrolyzed polyacrylamide inofanira kuva yakaoma upfu, anionic, ine molecular uremu kwete asingasviki mamiriyoni mashanu uye dhigirii hydrolysis 30%.
(4) Hydrolyzed polyacrylonitrile: Sarudzo ye hydrolyzed polyacrylonitrile inofanira kuva yakaoma powder, anionic, molecular weight 100,000-200,000, uye dhigirii ye hydrolysis 55-65%.
(5) Soda ash (Na2CO3): Decalcify bentonite kuvandudza kushanda kwayo (6) Potassium humate: Black powder 20-100 mesh ndiyo yakanakisisa
2. Kugadzirira uye kushandisa
(1) Zvinyorwa zvekutanga mumatope ega cubic: 1. Bentonite: 5% -8%, 50-80kg.2. Soda ash (NaCO3): 3% kusvika 5% yevhu revhu, 1.5 kusvika 4kg yesoda ash.3. Hydrolyzed polyacrylamide: 0.015% kusvika 0.03%, 0.15 kusvika 0.3kg.4. Hydrolyzed polyacrylonitrile yakaoma poda: 0.2% kusvika 0.5%, 2 kusvika 5kg yehydrolyzed polyacrylonitrile yakaoma poda.
Uye zvakare, zvinoenderana nemamiriro ekuumbwa, wedzera 0.5 kusvika 3 kg yeanti-slumping agent, plugging agent uye fluid kurasikirwa inoderedza agent pa cubic mita yematope.Kana iyo Quaternary formation iri nyore kudonha nekuwedzera, wedzera nezve 1% anti-collapse agent uye inenge 1% potassium humate.
(2) Gadziriro yekugadzirira: Mumamiriro ezvinhu akajairika, inenge 50m3 yedhaka inodiwa kuchera 1000m chibhorani.Tichitora kugadzirira kwe20m3 madhaka semuenzaniso, maitiro ekugadzirira e "double polymer mud" ndeaya anotevera:
1. Isa 30-80kg yesoda ash (NaCO3) mumvura 4m3 wosanganisa zvakanaka, woisa 1000-1600kg yebentonite, sanganisa zvakanaka, wonyika kweanopfuura mazuva maviri usati washandisa.2. Usati washandisa, wedzera dhaka rakaputirwa mumvura yakachena kuti uinyungudze kuita 20m3 base slurry.3. Dissolve 3-6kg ye hydrolyzed polyacrylamide poda yakaoma nemvura uye woiwedzera kune base slurry;dilute uye nyungudutsa 40-100kg yehydrolyzed polyacrylonitrile poda yakaoma nemvura uye woiwedzera kune base slurry.4. Gadzirai zvakanaka mushure mekuwedzera zvose zvinoshandiswa
(3) Performance test Izvo zvakasiyana-siyana zvedhaka zvinofanira kuongororwa uye kuongororwa zvisati zvashandiswa, uye imwe neimwe parameter inofanira kusangana nemitemo inotevera: yakasimba chikamu chemukati: isingasviki 4% chaiyo giravhiti (r): isingasviki 1.06 funnel viscosity (T) : 17 kusvika 21 masekonzi Huwandu hwemvura (B): isingasviki 15ml/30 maminitsi Keke yedhaka (K):

Composite low solid phase anti-collapse dope
1. Zvimiro
1. Yakanaka fluidity uye simba rakasimba rekutakura rock powder.2. Kurapa nyore kwematope, kugadzirisa kwakakodzera, kushanda kwakagadzikana uye hupenyu hurefu hwebasa.3. Kushandiswa kwakakura, inogona kushandiswa kwete chete mumarara, akaputsika uye akaputsika, asiwo mumadhaka akaputsika dombo uye mvura-inonzwa dombo stratum.Inogona kusangana nemadziro ekudzivirira zvinodiwa zvemhando dzakasiyana dzedombo.
4. Zviri nyore kugadzirira, pasina kupisa kana kutangira kunyura, kungovhenganisa maviri-yakadzika-yakasimba chikamu slurries uye fambisa zvakanaka.5. Rudzi urwu rwemusanganiswa anti-slump mud haruna kungova ne-anti-slump function, asiwo ine basa rekudzivirira-kudonha.
2. Kugadzirira kwekombiki yakaderera-yakasimba anti-slump matope A mvura: polyacrylamide (PAM) ─potassium chloride (KCl) yakaderera-yakasimba anti-slump dope 1. Bentonite 20%.2. Soda ash (Na2CO3) 0.5%.3. Sodium carboxypotassium cellulose (Na-CMC) 0.4%.4. Polyacrylamide (PAM molecular weight is 12 million units) 0.1%.5. Potassium chloride (KCl) 1%.Liquid B: Potassium humate (KHm) yakaderera chikamu chakasimba chinopesana nekudonha madhaka
1. Bentonite 3%.2. Soda ash (Na2CO3) 0.5%.3. Potassium humate (KHm) 2.0% kusvika 3.0%.4. Polyacrylamide (PAM molecular weight is 12 million units) 0.1%.Paunenge uchishandisa, sanganisa mvura yakagadzirwa A uye yemvura B pachiyero che1: 1 uye simbisa zvakakwana.
3. Mechanism Analysis yeComposite Low Solids Anti-slump Mud Wall Protection
Liquid A is polyacrylamide (PAM) -potassium chloride (KCl) low-solid anti-slump mud, iro idhaka remhando yepamusoro rine mashandiro akanaka ekurwisa kudonha.Iyo yakasanganiswa mhedzisiro yePAM neKCl inogona kunyatso kuvharira hydration yekuwedzera yemvura-sensitive formations, uye ine yakanaka kwazvo inodzivirira inokonzeresa pakudhirowa mumvura-sensitive formations.Iyo inobudirira inhibits kuwedzera kwe hydration yerudzi urwu rwekugadzira dombo panguva yekutanga apo kuumbwa kwemvura-kunzwa kunoratidzwa, nokudaro kudzivirira kuparara kwegomba remadziro.
Liquid B is potassium humate (KHm) yakaderera-yakasimba anti-slump mud, iyo ivhu repamusoro-soro rine maitiro akanaka ekudzivirira kudonha.KHm inzvimbo yemhando yepamusoro yekurapa madhaka, ine mabasa ekudzikisa kurasikirwa kwemvura, kunyungudutsa uye kuparadzira, kudzivirira kudonha kwemadziro egomba, uye kuderedza nekudzivirira kukwira kwedhaka mumidziyo yekuchera.
Chokutanga pane zvose, panguva yekutenderera kwe potassium humate (KHm) yakaderera-yakasimba chikamu chekudzivirira-kudonha dhaka mugomba, kuburikidza nepamusoro-soro kutenderera kwepombi yekuchera mugomba, potassium humate uye ivhu mumatope zvinogona kunyura. mune yakasununguka uye yakaputsika dombo kugadzirwa pasi pechiito che centrifugal force.Iyo yakasununguka uye yakatyoka yedombo strata inoita basa rekusimbisa uye kusimbisa, uye inodzivirira hunyoro kubva mukati uye kunyudza mudhuri wegomba pakutanga.Chechipiri, apo pane mapeji uye kuora mwoyo mumadziro egomba, ivhu uye KHm mumatope zvichazadzwa mumapupa uye kuora mwoyo pasi pechiito che centrifugal force, uye ipapo gomba remadziro richasimbiswa nekugadzirisa.Pakupedzisira, potassium humate (KHm) yakaderera-yakasimba chikamu chekudzivirira-kudonha dhaka inotenderera mugomba kweimwe nguva yenguva, uye zvishoma nezvishoma inogona kuumba ganda rakatetepa, rakaoma, rakaoma, uye rakatsetseka pamadziro egomba, iro rinowedzera kudzivirira. inodzivirira kubuda uye kuputika kwemvura pamadziro epore, uye panguva imwechete inoita basa rekusimbisa rusvingo rwepore.Iro ganda revhu rakatsetseka rine mhedzisiro yekudzikisa kudhonza pane chibooreso, kudzivirira kukuvadzwa kwemichina kumadziro egomba kunokonzerwa nekudengenyeka kwechigadzirwa chekuchera nekuda kwekupokana kwakanyanya.
Kana mvura A uye mvura B yakasanganiswa mudhaka rimwechete pachiyero che1: 1, mvura A inogona kuvharidzira kuwedzera kwe hydration ye "yakaputsika madhaka" kuumbwa kwedombo kekutanga, uye mvura B inogona kushandiswa mukati. kekutanga Inobata basa mu dialysis uye cementation ye "yakasununguka uye yakaputsika" maumbirwo ematombo.Sezvo mvura yakasanganiswa inotenderera mugomba kwenguva yakareba, mvura B ichagadzira zvishoma nezvishoma ganda revhu muchikamu chegomba rose, nokudaro zvishoma nezvishoma kutamba basa guru rekudzivirira rusvingo nekudzivirira kuparara.
