Nheyo uye nzira yekushanda yemagnetic positioning perforation

Zvinoenderana nezvinodiwa nehurongwa hwekuvandudza, perforating ndeye kushandisa yakakosha mafuta tsime perforator kupinda mukati mecasing madziro uye simende mhete yekuvharira yechinhu chinotarirwa kugadzira gomba rekubatanidza pakati peyakanangwa layer uye casing tsime. Naizvozvo, perforation inhanho yakakosha yekuvandudzwa kweoiri uye nzira yakakosha yekugadzirwa kwemafuta, gasi uye mvura.

1.the working principle of magnetic positioner

Izvo zvinozivikanwa kubva mumutemo we electromagnetic induction kuti kana magineti kana coil iri mukufamba kwakafanana, iyo magineti flux yehukuru.

etic munda wakatenderedza coil shanduko, iyo magineti waya inocheka iyo coil inotendeuka uye inogadzira iyo induced inogoneka uye induced ikozvino, iyo coil haisi loop, hapana induced ikozvino, chete induced kugona iripo. Mamiriro ekutanga emagetsi emagetsi induction ndeye magineti waya-akacheka coil yegineti yakatenderedza coil, uye kugadzira iyo magineti waya-yakacheka coil, iyo magineti inoyerera yegineti yakatenderedza coil inofanira kuchinjwa. Iko ndiko kuti, magineti uye coil zviri mukufamba kwakafanana, asi chimiro cheiyo magineti chinzvimbo hachibvumire magineti uye coil kuti ive mukufamba kwakasiyana, ipapo iyo magineti inoyerera yakatenderedza coil haizoshanduke, uye haigone kugadzira. induction kugona, kuitira kuti isu tigone kushandisa imwe fomu remagineti flux shanduko, ndiko kuti, kuvimba nekune dzimwe nyika ferromagnetic zvinhu shanduko. Iyo inonyanyiswa inogoneka inogadzirwa neyekunze ferromagnetic zvinhu inobata yayo yega magineti inoratidza shanduko yekunze nharaunda. Naizvozvo, kana iyo magineti inotsvedza nepakati pecollar mune casing, iyo magineti mutsara wekugovera mutsara unoshanduka nekuda kwekuchinja kwehupamhi hwekunze kweferromagnetic zvinhu - iyo casing wall, kuitira kuti induction inogona kuburitswa nekucheka coil. Kana iyo magnetic locator signal waveform ichirekodhwa pachiridzwa chepamusoro, zvinozotemwa kuti iyo magineti locator iri kupfuura nepakora pane imwe kudzika mutsime. Saka, inogona kurongeka neyakadzama chikamu chechiridzwa chepasi kuti ipedze basa rekuisa perforation.

2.Comply ne perforating site operating procedures

(1) Uraya zvakanaka maererano nezvinodiwa zvechirongwa chekugadzira.

(2) Gadzirira midziyo yetsime uye kuiswazvishandiso zvekugadzirira zvinobudirira kudzivirira kuputika.

(3) Isati yaputika, casing inofanira kupfuurakuburikidza netsime maererano nemirairo, jecha rinosuka tsime kusvika pasi pechitsime chegomba.

(4) Casing pressure inofanira kuongororwa uye cotsime risati raboborwa.

(5) The perforation udzamu kukanganisa simba haifaniri kudarika 0.1m.

(6) Kana iyo perforation mita inodarika 3m,tsime rinogona kupedzwa chete mushure mokunge tambo yepombi yashambidzwa.

(7) Chitubu chemagetsi chinofanirwa kuongororwa after perforating, iyo extrusion vhoriyamu yakakura kupfuura 1m³, iyo extrusion pressure isingasviki 15MPa, uye extrusion nguva haisi pasi pe5min.

(8) Munguva ye perforating process,panofanira kunge paine munhu akakosha kuti atarisire musoro wetsime, kudzivirira zvinhu zvinodonha, uye teerera kana paine mafuta uye gasi kuratidza. Kana mafashama akawanikwa, kupenya kunofanira kumiswa, tambo yepombi inofanira kubatwa nekukasira, uye mvura yekoramu pressure inofanira kugadziridzwa isati yapera.

(9) Mukuita kwecannonball, kanapane kuramba, usave wakaoma, unofanirwa kuisa mberi cannonball, uye kutora matanho anoenderana mushure mekudzidza mamiriro epasi pevhu.

(10) Munguva yose yekuvakation process, timu yekushanda inofanirwa kushanda padhuze nechikwata cheperforating kuti iwane yakachengeteka perforation, uye hapana firework inotenderwa kutenderedza tsime.

(11) Perforation data collection:

① Ongorora perforation kuvaka cards;

② Kuyera kuwanda kwemvura inouraya;

③ Iyo perforating nzira ndeye pfuti type;

④ Vhura kuumbwa, tsime nguva, nhamba yeholes, emissivity;

⑤ Chii chinoratidzwa mushure mekuputika;

⑥ Perforating nguva uye kumhanya kurongeka;

⑦ Mamwe mamiriro ezvinhu.
