I-API 7-1 4145 kunye neKhola yokubhola engeyomakhi

Inkcazo emfutshane:

I-Drill Collar yenziwe ngentsimbi ecinyiweyo nethambileyo ye-AISI 4145H kwaye iphathwa ngobushushu kuyo yonke ubude bayo ukuze iqine ngokulinganayo kwaye ihlale ixesha elide. Uvavanyo oluqinileyo lwe-metallurgical lwenziwa ngokweemfuno ukuqinisekisa ukuba unyango lobushushu luvelisa ubunzima obuhambelanayo nobuphezulu kubunzulu bebha.

I-Landrill inika iikhola zokubhola ezisemgangathweni kwaye zijikelezwe ukusuka kwi-3-1/8” OD ukuya kwi-14” OD ngokweenkcazo ze-API, NS-1 okanye ze-DS-1.

Ingcaciso yeMveliso

Ikhola yokubhola eqhelekileyo yinxalenye engqukuva ejikelezayo, embindini inomngxuma wamanzi, ubukhulu bodonga bukhulu, umlomo wayo mncinci, ubunzima bayo bungaphezulu kobukhulu bombhobho wokubhola phantse amaxesha ama-4-5. Uninzi lwekhola yokubhola lulungiswa ngqo emzimbeni wombhobho, kodwa ezinye zazo zisebenzisa ijoyinti etshintshiweyo.

Ikhola yokubhola ejikelezayo luhlobo lwesixhobo sokubhola ipetroliyam. Olu hlobo lwekhola yokubhola luyakwazi ukuthintela ukubanjwa koxinzelelo oluhlukeneyo lwezixhobo ngexesha lokubhola. Imijelo ejikelezayo iya kwenza udaka luhambe ngokukhululekileyo lujikeleze ikhola yokubhola ukuze kusetyenziswe uxinzelelo lokulinganisela ukuthintela ukwakheka kokuvaleka ukuze kuthintelwe ngempumelelo ukuvaleka koxinzelelo oluhlukeneyo. Indawo yokunxibelelana eludongeni lomthombo inganqunyulwa ukuze kuncitshiswe ngempumelelo amathuba okwenza ukuvaleka koxinzelelo oluhlukeneyo. Imijelo ejikelezayo iya kwenza udaka luhambe ngokukhululekileyo lujikeleze ikhola yokubhola ukuze kusetyenziswe uxinzelelo lokulinganisela ukuthintela ukwakheka kokuvaleka ukuze kuthintelwe ngempumelelo ukuvaleka koxinzelelo oluhlukeneyo. Indawo yokunxibelelana eludongeni lomthombo inganqunyulwa ukuze kuncitshiswe ngempumelelo amathuba okwenza ukuvaleka koxinzelelo oluhlukeneyo. Ubunzima bekhola yokubhola ejikelezayo bungaphantsi nge-4-6% kunobo bekhola yokubhola ejikelezayo.

Ikhola yokubhola engeyoMagnetic: Iikhola zokubhola ezingeyoMagnetic zenziwe ngezinto zekhola yokubhola engeyoMagnetic ezinamandla aphantsi ngokudibanisa uhlalutyo lweekhemikhali oluzimeleyo kunye nenkqubo yokubumba ngehamile ejikelezayo enomoya ophantsi wombane. Singakwazi ukubonelela ngobude ukusuka kwi-10 ukuya kwi-42 yeenyawo kunye nobubanzi bangaphandle ukusuka kwi-3 1/8" ukuya kwi-11'.

Iimpawu kunye neeNzuzo

Uluhlu lobunzima obuphakathi kwe-285 ukuya kwi-341 BHN kunye nexabiso le-Charpy eliyi-40 ft-lbs liqinisekisiwe kwiingongoma ezili-16 ezisasazwe ngokulinganayo kuyo nayiphi na indawo enqamlezileyo kubushushu begumbi;

Iziqhagamshelo zigqunywa nge-phosphate emva kokwenziwa ukuze kukhuselwe imisonto kwizinto ezirhabaxa kwaye kuthintelwe ukurhawuzelelwa xa kusenziwa ulwelo okokuqala;

Iingcambu zemisonto ziqengqeleka ngokubandayo kwiikhonkco ze-API;

Izikhuseli zentsimbi ezicinezelweyo zibonelelwa kuzo zonke iikhola zokubhola ezixhotyiswe ngoqhagamshelo oluqhelekileyo.

Iinketho

I-groove yokunciphisa uxinzelelo. I-relaxation features kwi-API pin kunye neebhokisi zokudibanisa ukunciphisa uxinzelelo oluphezulu ngaloo ndlela kuphucula amandla okugoba ajikeleze iindawo zonxibelelwano.
Ukuqengqeleka kweengcambu zemisonto ngokubandayo kubonakalise imiphumo emihle yokuphucula ukumelana nokudinwa kwezixhobo ngokunciphisa ukuqaliswa kokuqhekeka.

Ukubopha i-Hardband. Ukubopha i-Hardband kwiindawo ezingaphantsi nangaphezulu kwe-slip recess okanye kwi-pin shoulder kwandisa ubomi benkonzo yee-drill collars. Kungasetyenziswa nakwii-configurations ezichazwe ngabathengi.
