Izinto ezichaphazela uMgangatho woKwemba kunye nesantya

1. Ekubeni i-drill bit speed ye-compound drilling iphinda kabini i-gear II ye-drilling rig, kwaye phantse amaxesha amane e-gear I, kulula ukwandisa kakhulu i-ROP.

I-2.Isantya esiphezulu sokujikeleza kwe-compound drilling ifanelekile kwiimpawu zokusika ze-PDC bit ekubunjweni kwe-shear.

3.Wellbore trajectory igudile. Ukudibanisa i-drilling directional drilling kunye ne-sliding drilling ukwenzela utshintsho lwexeshana, kulula ukulawula i-angle ye-dogleg kunye nokuqinisekisa ukhuseleko lwe-downhole.

4.Isakhiwo sesixhobo sokubhola senziwe lula ngokufanelekileyo. Ngexesha lokugaya i-compound drilling, uxinzelelo lwe-drilling ngokuqhelekileyo <100-120kN, kwaye iimfuno zokugaya zingagqitywa ngeekholeji ezincinci okanye zingabikho, kwaye amathuba okubambelela ayancipha kakhulu.

5. I-PDC ye-drill ye-drill ephezulu isebenzisana nesixhobo sokubhoboza amandla ukugaya amaqula, okuthintela ukungaphumeleli kwangaphambili kwe-cone ethwele ngesantya esiphezulu kwaye engabangeli iingozi zokulahleka kwe-cone.

Impembelelo yeeParameters zokuBomba kwiSpeed ​​​​Speed ​​Quality

Ngexesha lenkqubo yokomba, impembelelo yeeparameters zokomba phakathi kwezinto ezilawulwayo kwisantya sokomba ayinakungahoywa, njengale: uhlobo lwe-bit, i-bit nozzle, i-bit, i-bit, i-bit, i-speed pressure, i-speed pressure, i-displacement, njl. imeko yeemeko ezithile zenjongo, i-ROP idla ngokunyuka ngokulawula uxinzelelo lokugaya, isantya sokujikeleza, uxinzelelo lwempompo kunye nokufuduka.

Impembelelo yokuNgqobhoza kuMgangatho wokuBomba kunye nesantya

I-drilling fluid ligazi lokomba, ngoko ukusebenza kwe-drilling fluid kubaluleke kakhulu ekuqhubeni. Izinto eziphambili ezichaphazela i-ROP yi-viscosity ye-drilling fluid, ubuninzi be-drilling fluid kunye nomxholo oqinileyo kwi-drilling fluid. Kwimbono yokuba i-arhente yonyango esetyenziswa kwinkqubo ekhoyo yolwelo olunzulu ekhoyo ityebile kwii-ion zechromium kunye nezinye ii-ion zetsimbi enzima ezinempembelelo enkulu kwindalo esingqongileyo, kuyacetyiswa ukuba ufunde kwaye usebenzise ulwelo lokugrumba nzulu ngokusingqongileyo. inkqubo yokuphucula i-silicate drilling fluid system esetyenziswayo ngoku kuluhlu oluncinci e-China , Inkqubo yokugaya i-Synthetic esisiseko yokwenza i-deep well-deep drilling fluid series efanelekileyo kwiimeko ze-geological and engineering zommandla ngamnye wokomba.
