Yintoni umsebenzi weePaki kwi-oyile kunye negesi?

IiPackers zizixhobo zokulahla phantsi ezisetyenziselwa ungenelelo olwahlukeneyo kunye nemisebenzi yokuvelisa ukudala ukwahlukana phakathi kwe-tubing kunye ne-casing.

Ezi zixhobo zinedayamitha encinci xa ziqhutywa emngxunyeni kodwa kamva xa ubunzulu obujoliswe kubo bufikelelwe ziyanda kwaye zityhale kwi-casing ukuze zinikeze ukwahlula.

Abapakishi bemveliso basetyenziselwa ukukhusela iityhubhu yemveliso equleni kunye nokubonelela ngokuzimeleyo kwi-tubing / casing annulus emva kokuba iqula ligrunjwe kwaye livuselelwe.

Ngokuthintela ulwelo lwamaqula ekudibaneni ne-casing kunye nokwenza umhlwa, ubomi bayo bunokwandiswa.

Ngokuqhelekileyo kulula kakhulu ukutshintsha iityhubhu yemveliso kunokulungisa i-casing eyonakeleyo.

Izipakishi zihlala zisetyenziselwa imisebenzi eyahlukeneyo yokugqibezela iqula elinje ngokuqhekeza, ukwenza iasidi, okanye ukufaka isamente.

Kwezi zicelo, umpakishi udla ngokuqhutywa emngxunyeni njengenxalenye yendibano esezantsi yomngxuma.

Emva kokuba umsebenzi ugqityiwe (umzekelo ummandla waphukile) umpakishi akasetwanga kwaye isixhobo sinokufuduselwa kwindawo elandelayo.

Ngawaphi aMalungu aphambili ePaki?

I-Mandrel - umzimba wepaki

I-Slips - isetyenziselwa ukubamba ngokubhekiselele kwi-diameter yangaphakathi (ID) ye-casing kunye nokuthintela umpakishi ukuba ahambe.

I-Packing-element - ngokuqhelekileyo i-rubber element ebonelela ngokuzimela. Le element iyanda xa umpakishi efikelela kubunzulu obufunwayo kwaye usetwe.

Ikhowuni – into etyhala kwiziliphu xa kusetyenziswa amandla angaphandle.

Umsesane wokutshixa - uthintela umpakishi ukuba angamiseli xa kususwa amandla angaphandle.

Iintlobo zePackers

Abapakisheli bohlulwe babe ziindidi ezimbini eziphambili: ezisisigxina nezinokubuyiswa.

Iipakethe ezisisigxina zisetyenziswa kwimisebenzi engafuni ukususwa kwangoko.

Babonelela ngotywino olungcono kuneepakethe ezinokubuyiswa kwaye zihlala zitshiphu.

Ukuba kuyimfuneko, abapakishi abasisigxina banokususwa ngokusila nge-tubing edibeneyo.

Ngokuqhelekileyo, kwiindawo eziphezulu zokushisa kunye noxinzelelo oluphezulu, iipakethi ezisisigxina zikhethwayo.

Iipakethe ezibuyiselwayo zinokususwa ngokulula kwaye ziphinde zisetyenziswe kwakhona ngokusebenzisa amandla angaphandle kubo.

Zihlala zisetyenziselwa imisebenzi yokungenelela kakuhle apho iindawo ezithile kufuneka zibekwe zodwa amaxesha amaninzi ngexesha lokusebenza.
