I-spiral seam efakwe emanzini i-arc welded steel pipe igrunjwa ngokujikeleza kwaye iqala ukungena kukwakheka okuthambileyo.Ngaphantsi kwesenzo se-tri-cone, i-drill kuqala ivelisa i-elastic shear deformation ye-stratum kwaye isuswe phantsi koxinzelelo lwe-tri-cone.Kwimeko edibeneyo, umhlaba othambileyo ungudongwe olulinganayo, kungakhathaliseki ukuba i-stratum kunye nokuqhekeka komhlaba.I-Horizontal directional drilling iqhutyelwa kwi-formation ngokukhawuleza, kwaye ukubunjwa ku-random kunye ne-dynamic contact kunye ne-roller cone bit.Ukukhuhlana kwenzeka xa ikhowuni idibana nomhlaba.Amandla empembelelo abangela ukuba umthungo ojikelezayo ontywiliselwe i-arc wentsimbi umbhobho wentsimbi ungcangcazele.Xa isuntswana le-tri-cone lisuka kulwakhiwo oluthambileyo ukuya kulwakhiwo oluqinileyo, ngokuqinisekileyo luya kuvelisa ukungcangcazela okukhulu okusecaleni kunye nokunyuka nokuhla kwentshukumo.

Xa isantya sokomba siyi-0.008m/s kunye nesantya sokujikeleza kancinci si-2 radians / s, igophe lamandla e-pseudo-strain ngexesha lenkqubo yokuqhubela phambili ye-roller cone bit ikakhulu ibandakanya i-viscosity kunye ne-elasticity.Nangona kunjalo, kuba igama le-viscous lihlala lilawula, ukuguqulwa kwamandla amaninzi kumandla oxinzelelo lwepseudo alunakuguqulwa.I-deformation energy ye-spiral seam submerged arc welded steel pipe ngawona mandla asetyenzisiweyo ukulawula ukuguqulwa kwehourglass.Ukuba i-pseudo strain energy iphezulu kakhulu, oko kuthetha ukuba amandla okulawula ukuguqulwa kwe-hourglass inkulu kakhulu, kwaye i-mesh kufuneka icocwe okanye iguqulwe.Ukunciphisa uxinzelelo olugqithisileyo lwe-pseudo amandla.Utshintsho olukhawulezileyo lwe-pseudo strain energy kulo mzekelo luyenzeka ikakhulu xa i-drill bit ingena kumaleko omhlaba othambileyo kwaye i-cone bit idlula kwi-interface yokwakheka kotshintsho ngequbuliso.Okukhona ukuqina kokwakheka, kokukhona ukuqina koxinzelelo lwe-pseudo kwi-drill bit ekubunjweni.Linganisa inkqubo yokomba yombhobho we-spiral welded ekubunjweni ngokukhawuleza kwaye uqikelele utshintsho lwe-drill bit's drilling trajectory.

(1) Utshintsho olukhawulezileyo lwamandla obuxoki luyenzeka ubukhulu becala xa i-drill bit ingena kumaleko othambileyo womhlaba kunye nentwana yecone iwela ujongano lwenguquko yokwakheka ngesiquphe.Okukhona buphezulu ubulukhuni bokubumba, kokukhona amandla angeyonyani e-spiral seam antywiliselwe i-arc welded steel pipe xa ingena kwinkqubo yokuyila.

(2) Xa kusembiwa kulwakhiwo ngesiquphe, i-spiral seam entywiliselweyo i-arc welded steel pipe ihamba ngobude kwaye intwana ye-drill iyangcangcazela.Ubunzima obukhulu bokwakheka, ngakumbi i-amplitude ye-drill bit.

(3) Phantsi kwemeko yediphu ethile yestratum, kokukhona isantya sokomba sikhulu, kokukhona ukutenxa kwilongitudinal kwindlela yokomba, kwaye kokukhona isantya sesuntswana lokomba, kokukhona sincipha ukutenxa kwilongitudinal yendlela yokomba.Xa isantya sokujikeleza kancinci singaphantsi kwe-2.2rad / s, impembelelo yesantya sokujikeleza kwi-longitudinal deteation ye-drilling trajectory iyancitshiswa.

(4) Kwisantya esithile sokujikeleza, xa idip angle yokwakheka kwendawo ingu-0° kunye ne90°, ayinayo impembelelo kwi-drilling trajectory;xa i-angle yediphu yendawo ikhula ngokuthe ngcembe, ukuphambuka kwe-longitudinal yendlela yokwemba kuyanda;xa i-engile yediphu yendawo ingaphezulu kwama-45°, Impembelelo kwi-trajectory ye-drilling longitudinal deviation iyancitshiswa.Iziphumo zophando kwesi sahluko zibaluleke kakhulu ekuphuculeni ukuchaneka kwe-tri-cone drill bit kwiminqantsa kwaye ibeka isiseko sethiyori sokulungiswa kwe-spiral seam entywiliselwe i-arc welded steel welding trajectory yokomba ngomngxuma wokulinga othe tye.
