Iyo spiral seam yakanyura arc welded simbi pombi inoboorwa mukutenderera uye inotanga kupinda munyoro kuumbwa.Pasi pekuita kwe tri-cone, chibooreso chinotanga kuburitsa elastic shear deformation ye stratum uye yozobviswa pasi pekumanikidzwa kwe tri-cone.Munzvimbo inofananidzwa, ivhu rakapfava ivhu rakafanana, zvisinei netambo uye kuputika muvhu.Horizontal directional drilling inoitwa mukukurumidza kuumbwa, uye magadzirirwo ari mune zvisina kujairika uye ane simba kusangana neroller cone bit.Kupokana kunoitika kana koni yasangana nepasi.Simba rekuita rinoita kuti spiral seam yakanyura arc welded simbi pombi izununguke.Kana iyo tri-cone bit ikafamba kubva payakapfava kuumbwa ichienda kune yakaoma kuumbwa, inozoburitsa hombe lateral vibration uye kumusoro nekudzika kwevibration.

Kana kumhanya kwekuchera kuri 0.008m/s uye bhiti kutenderera kumhanya kuri 2 radians/s, pseudo-strain simba curve panguva yekufambira mberi kweiyo roller cone bit inonyanya kusanganisira viscosity uye elasticity.Nekudaro, sezvo izwi rekuti viscous rinowanzo kutonga, shanduko yesimba rakawanda kuita pseudo strain simba haidzokerike.Iyo deformation simba ye spiral seam yakanyura arc welded simbi pombi ndiro simba guru rinoshandiswa kudzora deformation ye hourglass.Kana iyo pseudo strain energy yakawandisa, zvinoreva kuti simba rekumanikidza rinodzora deformation ye hourglass yakakura kwazvo, uye mesh inofanira kunatswa kana kuchinjwa.Kuderedza kuwandisa kwepseudo strain simba.Iko kamwe-kamwe kushanduka kwepseudo strain simba mumuenzaniso uyu kunonyanya kuitika kana chibooreso chichipinda muvhu rakapfava uye bhiti rekoni rinopfuura nepakati pekusangana kwekuchinja kamwe kamwe.Iyo yakakura kuoma kwekuumbwa, iyo yakakura iyo pseudo strain simba re drill bit mukugadzira.Tevedzera nzira yekuchera ye spiral welded pombi mukukurumidza kuumbwa uye kufanotaura shanduko yekuchera bhiti rekuchera trajectory.

(1) Iko kamwe-kamwe shanduko yepseudo-strain simba inonyanya kuitika kana chibooreso chichipinda muvhu rakapfava uye bhiti rekoni rinoyambuka chiratidziro chekuchinja kamwe kamwe.Kukwirira kuoma kwekuumba, ndiko kukura kwesimba rekunyepedzera re spiral seam yakanyura arc welded simbi pombi kana ichipinda mukugadzira.

(2) Paunenge uchiboora mukati mekugadzirwa kamwe-kamwe, spiral seam yakanyura arc welded steel pombi inofamba ichireba uye chibooro chinozunguzika.Iyo yakakura kuoma kwekuumbwa, iyo yakakura amplitude ye drill bit.

(3) Pasi pemamiriro eimwe stratum dip, iyo yakakura kumhanya kwechibhorani, iyo yakakura kutsauka kwelongitudinal yenzira yekuchera, uye yakakura kumhanya kwebhiti, kudiki kutsauka kwelongitudinal kwenzira yekuchera.Kana iyo bit kutenderera kumhanya yakadzikira pane 2.2rad/s, pesvedzero yekutenderera kumhanya pakutsauka kwelongitudinal yekuchera trajectory inoderedzwa.

(4) Pane imwe bhiti kutenderera kumhanya, kana yeko maumbirwo dip angle iri 0° uye 90°, haina mhedzisiro pane yekuchera trajectory;apo dip angle yemunharaunda inowedzera zvishoma nezvishoma, kutsauka kwenguva refu kwekuchera trajectory kunowedzera;apo dip angle yemunharaunda inodarika 45°, Kufurira panzira yekuchera longitudinal kutsauka kunoderedzwa.Mhedzisiro yetsvakiridzo muchitsauko chino yakakosha zvikuru pakuvandudza kufembera kweiyo tri-cone drill bhiti mumateru maumbirwo uye kuisa hwaro hwetioretical hwekugadziriswa kwe spiral seam yakanyura arc welded simbi pombi yekuchera trajectory kuburikidza neyakachinjika pilot gomba.
