I-Drill Collars
I-drill collar njengengxenye yochungechunge lokubhoboza amashubhu ezimboni ngokwedlulele asetshenziselwa ukubhola emhlabathini ukuze anikeze isisindo kubhithi sokumba.Isetshenziselwa ukuhlanganiswa ne-drill pipe.Kunezinhlobo ezicwebezelayo nezivunguzayo ikakhulukazi.Inqubo yethu yokukhiqiza iqinisekiswe ku-API spec 7-1.Ikhola yokubhoboza yenziwe nge-AISI 4145 H noma i-4145 H Modified alloy steel.Izithukuthezi zihanjiswa ohlangothini olulodwa ngaphandle kokungafani.Wonke amakholomu okubhoboza aphathwa ngokushisisa ngobulukhuni phakathi kuka-285 kuya ku-341 BHN, aqinisekiswa iyintshi eyodwa ngaphansi kobuso bepayipi.
Amakholomu okubhoboza okungewona azibuthe anikeza amandla nobulukhuni kuyilapho evimbela ukuphazamiseka kazibuthe okungase kuthikameze ukunemba kokuhlola kazibuthe.Ikhiqizwa ngensimbi ekhethekile ene-permeability ephansi, izakhiwo eziphezulu zemishini kanye nokumelana okuphakeme nokuqhekeka kokugqwala.
Sinikezela ngamakholomu acwebile, amakhola okubhola asongekile kanye namakholomu okubhola angewona azibuthe;ubukhulu bawo busuka ku-3-1/8 kuya ku-11 amayintshi.Ngaphandle kwamakholola okubhola kuthebula elingezansi, singanikeza amanye amakholola ngokucela kwamakhasimende.

Amakholomu okugaya ayijoyinti elinzima elibalulekile elakhiwe ngebha eqinile ye-AISI 4145H modified alloy steel.?Amakholomu ethu ajwayelekile ahlinzekwa ngesimo sokuqeda indawo "egoqekile".Wonke amabha ajwayelekile athola ukwelashwa okushisa okubahlinzeka ngezinto ezidingekayo zokukhanda.
Ama-bar abese ehlukunyezwa futhi akhukhulwe.?Wonke amakholomu ethu okubhola akhiqizwa ngaphakathi
ngokuhambisana ne-API spec 7, Q1 kanye nokuzijwayeza okunconyiwe kwe-7G, njengoba kusebenza.
