Chibooreso chepombi yejojo ​​chikamu chepombi yekuboorera, yakakamurwa kuita majoini echirume uye majoini echikadzi, akabatana kumagumo emuviri wepombi yekuboorera. Iyo yekubatanidza inopihwa neshinda sikuruu shinda (gobvu screw thread) yekubatanidza imwe neimwe pombi yekuboorera. Muchibhorani, mubatanidzwa unowanzo patsanurwa, uye nzvimbo yakabatana inoiswa pasi pesimba rakawanda rekuruma, saka pombi yekuchera yakabatana pamadziro yakakura, iyo yakabatana yekunze dhayamita yakakura kupfuura iyo pombi muviri wekunze dhayamita, uye alloy simbi. nesimba rakakwirira rinoshandiswa. Domestic drill pombi majoini anowanzo gadzirwa ne35CrMo alloy simbi.

Kubatana kwescrew thread kunofanirwa kugutsikana nemamiriro matatu, ndiko kuti, saizi yakaenzana, mhando yeshinda yescrew yakafanana, uye shinda yechirume neyechikadzi inofananidzwa. Majoini saizi epombi yekuboora akasiyana akasiyana. Iyo thread yemhando yekuboora pombi yehukuru hwakafanana yakasiyanawo. Mhando yekubatana inoshandiswa nemugadziri wega wega wekuchera pombi yakaomawo kuti inyatsoenderana. Naizvozvo, kuitira kuti kufambisa mutsauko pakati pemajoini epombi yekuchera uye maenjiniya ekushandisa, API yakaita yunifomu gadziriro parudzi rwemajoini epombi yekuboorera, ichigadzira majoini epombi epiipi anowanzoshandiswa muindasitiri yepetroleum.

API pombi fittings inowanikwa mune zvese zvekare uye zvitsva zviyero. Iyo yekare API drill pombi yakabatana inokurudzirwa kushandiswa kwekutanga kwepombi yekubooresa yakanaka, iyo yakakamurwa kuva marudzi matatu: mukati furati (IF), perforated (FH) uye yenguva dzose (REG).

Iyo yemukati yakafuratira yejoini inonyanya kushandiswa kukora kwekunze kwepombi yekuchera, iyo inoratidzwa nemukati dhayamita yepombi yekuchera uye dhayamita yemukati yejoini pakukora kwepombi muviri, uye kudonha kwemvura kuyerera kudiki. , iyo inobatsira kuvandudza simba remvura ye drill bit, asi dhayamita yekunze yejoini yakakura uye iri nyore kupfeka.

Iyo perforated joint inokodzera kukora kwemukati wepombi yekuboorera, iyo inoratidzwa nemadiamediamets maviri emukati epombi yekuchera, uye dhayamita yemukati yejoinhi yakaenzana nedhayamita yemukati yekukora kwepombi muviri, asi isingasviki. iyo yemukati dhayamita yepombi muviri chikamu. Kupokana kwemvura yekuboora inoyerera nemujoini yakakura kupfuura iyo yemukati furati yakabatana, asi dhayamita yaro yekunze idiki pane iyo yemukati furati yakabatana.

Iyo yenguva dzose yakabatanidzwa inokodzera mukati mukati meiyo drill pipe. Iyo yemukati dhayamita yejoini iyi idiki, ishoma pane yemukati dhayamita yechiboora pombi thickening. Naizvozvo, kune matatu akasiyana madhayamita ekubooresa pombi yakabatana nemajoini akajairwa. Mvura yekuchera inoyerera nemujoini iri nekupikisa kukuru, asi ine dhayamita diki rekunze uye simba rakakura. Majoini enguva dzose anowanzo shandiswa diki dhayamita chibooreso nyere uye reverse chibooreso nyere, uyewo chibooreso, hove maturusi, etc. The matatu marudzi majoini ose anoshandisa "V" chimiro shinda, asi sikuruwa shinda mhando (inoratidzwa nehupamhi top cut), iyo screw thread kureba, taper uye saizi zvakasiyana zvakanyanya.

1.hole FH, XH, isingawanzi muchitoro chemidziyo, isingawanzo shandiswa.

2.inowanzo shandiswa IF uye yakajairika REG, musiyano unotevera:
KANA mabhatani mana painji imwe, shinda ine screw yakakora, uye taper idiki, REG 5 mabhatani pa inch, iyo hama screw thread idiki, uye taper yakakura. Saizi yeIF screw thread inotangira pa2-3/8 "kusvika 4-1/2", uye idzo dzakakura kupfuura 4-1/2 "hadzina IF, kazhinji REG, uko 7-5/8" uye pamusoro kwete REG.

3. Nzira yekutaura yakajairika:
Inomiririrwa nenhamba nhatu, senge 310,410,411, nezvimwe.

Nhamba yechipiri inoratidza rudzi rwescrew thread (kune 1, 2, 3), 1-- KANA; 2---FH; 3-- REG;
Nhamba yechitatu inomiririra murume nemukadzi (inomiririrwa ne0 uye 1)
0--Bhokisi( mukadzi); 1--Pini (murume);

4.other akajairika chibooreso chenyere sikuruu shinda mhando vari BTC, MT, AMT, HT55 uye zvichingodaro.

5.mukuwedzera, iyo yakajairika screw thread mhando yemota 7-5/8 "REG, 6-5/8" REG, 4-1/2 "REG, zvakare ine 4-1/2" IF. Iyo yakajairika screw thread mhando yepombi scraper uye hydraulic cutter ndeye REG.
