I-wireline coring system ibandakanya i-core barrel assembly kunye ne-overshot assembly.I-core barrel assembly ihlanganiswe neqela langaphakathi le-tube kunye neqela le-tube yangaphandle.Iibhubhu zangaphakathi & zangaphandle zinobude obuqhelekileyo be-1.5 yeemitha kunye neemitha ezi-3.

Indibano yentloko ibonelela: iindlela zokuqhawula kunye ne-pivoting ye-spearpoint ukuvumela ukufakwa kunye nokubuyiswa kwendibano ye-tube yangaphakathi, i-bearing assembly ukuvumela ityhubhu yangaphakathi ukuba ihlale imile kwaye igweme umonakalo wesampuli ngelixa i-drilling, izibonakaliso zokusebenza koxinzelelo lwe-fluid kunye ne-valve yokulawula umbane.

Zonke iindibano zentloko zibandakanya indibano yevalve evaliweyo ebonelela ngophawu loxinzelelo lwamanzi kumqhubi we-drill xa amalungu evalve ecinezelwe, ebonisa ityhubhu yangaphakathi epheleleyo okanye evaliweyo.

I-core barrel assembly yenziwe liqela langaphakathi lombhobho kunye neqela lombhobho wangaphandle.Iqela letyhubhu engaphakathi yenziwe: Indibano yeNtloko, iThubhu yaNgaphakathi, iCase yokuphakamisa uNdoqo, uMphakamisi oPhambili, uMsesane wokumisa.

Iqela langaphakathi lombhobho liqokelela isampuli engundoqo ngexesha lenkqubo yokugaya kwaye lizimele kwiqela le-tube yangaphandle.Iqela le-tube yangaphandle liqulunqwe yintsalela yamacandelo e-core barrel: i-Locking Coupling, i-Adapter Coupling, i-Outer Tube.

Iqela lombhobho wangaphandle lihlala lihlala lisezantsi komngxuma kwaye ligcina iqela langaphakathi letyhubhu ngexesha lenkqubo yokomba.
