Nhanganyaya YeHardbanding

Hardbanding is wear-resistant metallic coating Hardbanding inzira yekuisa pamusoro pesimbi kana pamusoro pesimbi yakaoma] pane imwe simbi yakapfava. Inoshandiswa negasi simbi arc welding pamusoro pekunze kwechibooreso chepombi chishandiso majoini kuwedzera kudhirowa kwepombi mudziyo majoini, makora, uye inorema huremu yekubooresa pombi yehupenyu hwesevhisi uye kuderedza kupfekwa kwetambo yecasing kubva pakupfeka zvine chekuita nemaitiro ekuchera.

Hardbanding inoiswa apo kutenderedzwa neaxial friction kwakabatana nekuchera nekugumburwa kunokonzeresa kusakara kwakanyanya pakati petambo yekuboorera necasing kana pakati pechibhorani nedombo. Hard alloy overlays inoiswa kune mapoinzi ekunyanya kuonana. Kazhinji, iyo hardbanding inoiswa kune iyo mudziyo wekubatanidza sezvo iri iyo yakakura chikamu chetambo yekubooresa uye ichaita kusangana necasing kazhinji.

Pakutanga, tungsten-carbide zvimedu zvakadonhedzwa mune yakapfava-simbi matrix, ichisara iyo indasitiri chiyero kwemakore mazhinji. Nekudaro, varidzi vematsime vakakurumidza kuona kuti nepo chibatanidza chekushandisa chakachengetedzwa zvakanaka, tungsten-carbide zvimedu zvaiwanzoita semudziyo wekucheka uchipokana necasing, zvichikonzera kuwanda kwekupfeka uye dzimwe nguva kutadza kwecasing. Kugadzirisa kudiwa kwakakosha kwecasing-inoshamwaridzika hardbanding chigadzirwa chinogona kudzivirira zvakakwana majoini emidziyo uye mamwe maturusi ekudzika.

Mhando dze hardbanding:

1. Yakasimudzwa hardbanding (KUDA)

2. Flush hardbanding (FLUSH)

3. Hardbanding pane central upset yeDrill Collar uye Heavy Weight Drill Pipe

Hardbanding mabasa:

1. Inodzivirira chibooreso chepombi yakabatana kubva pakupwanya nekupfeka uye inowedzera hupenyu hwesevhisi yeDP.

2. Inodzivirira majoini emudziyo kubva pakutsemuka kwemafuta.

3. Inoderedza kupfeka kwecasing.

4. Inoderedza kurasika kwekurasika kwekuchera.

5. Hardbanding inobvumira kushandiswa kwe slim OD welded tool joints.

Hardbanding application:

1. Hardbanding inoshandiswa pakuboora mapaipi emhando dzose nemagiredhi.

2. Hardbanding inogona kuiswa pane itsva uye u    sed tubular.

3. Hardbanding inogona kushandiswa pazvibooreso pombi mudziyo majoini akaitwa pa GOST R 54383-2011 uye GOST R 50278-92 kana paunyanzvi nokurondedzerwa enyika pombi zvigayo, uye pamusoro chibooreso pombi mudziyo majoini akaita pa API Spec 5DP.

4. Hardbanding inogona kuiswa pamapombi ekuboorera ane marudzi akasiyana-siyana emajoini emidziyo, kusanganisira majoini ezvishandiso zvemapfudzi maviri.

5. Hardbanding inogona kuiswa pamapombi ekuboorera asingatonhore uye sour-service DP.

Hardbanding inogona kuiswa pane tubular yeanotevera marudzi uye saizi:

1. Muviri wepombi OD 60 kusvika 168 mm, kureba kusvika ku 12 m, OD ye welded tool joints per DP zvinyorwa.

2. Hardbanding inoshandiswa pakugumburwa kweHWDP, panzvimbo yezvishandiso zvakabatana zveHWDP, neDC zvemarudzi ose nemasaizi.

3. Hardbanding inoshandiswawo kune pakati pekushungurudzika kweHWDP neDC.

4. Hardbanding inogona kuiswa pamajoini emudziyo asati aiswa weld kune pombi yekuchera.

Mari inochengetwa nekushandiswa kwepombi yekuchera ine hardbanding:

1. Drill pombi hupenyu hwebasa hunowedzerwa kusvika ku3 nguva.

2. Chishandiso chekubatanidza kupfeka chinoderedzwa ne 6-15 % zvichienderana nerudzi rwekusungirirwa kwakaiswa.

3. Kupfeka kwemadziro ekupfeka kunoderedzwa ne14-20% kana zvichienzaniswa nekupfeka kunokonzerwa nemajoini emidziyo.

4. Inoderedza kurasikirwa kwekukweshana kwematsime.

5. Inodiwa rotary torque yakaderedzwa, nokudaro kuderedza kushandiswa kwesimba.

6. Inovandudza kushanda kwekuchera.

7. Inoderedza nguva yekuchera.

8. Inoderedza kuwanda kwetambo yedrill uye casing tambo kukundikana mumabasa ekuchera.
