Iyo Yakazara Nhungamiro yePDC Nozzle Mhando uye Mashandisirwo

Muminda yakadai sekuchera oiri uye geological exploration, PDC (Polycrystalline Diamond Compact) nozzles dzave zvinhu zvakakosha zvinovimbisa kudhirowa kwemhando uye hunhu, nekuda kwekunaka kwekupfeka, kuramba kwekushisa, uye kukanganisa kupikisa. Vanoona mabasa akaita sekupwanya kwedombo, kuchenesa dombo, uye drill bit cooling kuburikidza nehigh-pressure jet fluid. Mhando dzakasiyana dzePDC nozzles dzakakodzera kune akasiyana mamiriro ekushanda. Iwo anotevera anodonongodza maitiro avo uye anowirirana mashandisirwo.

1. Kurongwa neStructural Design

PDC nozzles inonyanya kukamurwa kuva mhando nhatu zvichienderana nekugadzirwa kwemaitiro: yakananga-jekiseni mhando, inotenderera mhando, uye hybrid mhando.

Yakananga-jekiseni PDC nozzles: Gamuchira yakatwasuka-chiteshi chimiro. Iyo jet inoyerera inonamirwa nesimba rakasimba rekuita, iro rinogona kukurumidza kuputsa matombo akaomarara. Iwo anoshandiswa zvakanyanya mukudhirowa kwedombo rakaomarara kumatsime akadzika uye ekupedzisira-akadzika matsime, zvinobudirira kuvandudza kushanda kwedombo-kupwanya uye kuderedza dhill bit kupfeka.

Swirling PDC nozzles: Yakashongedzerwa ine spiral inoyerera-inotungamira chimiro mukati. Kana mvura yaiswa jekiseni, inotenderera inoyerera munda inoumbwa, iyo isingango wedzera kugona kwekuchenesa kwematombo ekucheka pasi pegomba asi zvakare inoderedza kudzvanywa kwepasi pasi. Izvo zvakakodzerwa kudhirowa zvimiro zviri nyore kudonha maumbirwo kana maumbirwo ane yakakwira jecha, kudzivirira matombo ekucheka kubva pakuunganidza uye kukanganisa kufambira mberi kwekuchera.

Hybrid PDC nozzles: Sanganisa mabhenefiti emhando mbiri dziri pamusoro, iine ese ari maviri akananga-jekiseni simba rekuita uye inotenderera yekuchenesa maitiro. Vanoita zvakatanhamara mumabasa ekuchera mumhando dzakaoma, senge horizontal tsime kuchera mu shale gasi kukura. Vanogona kuenzanisa zvinodiwa zvekupwanya kwedombo uye kuchenesa dombo, kuvandudza kugadzikana kwese kwekuchera.

2. Classification by Functional Application

Zvinoenderana nekushanda kwekushandisa, PDC nozzles inogona kukamurwa kuita iyo yekupwanya dombo, kuchenesa dombo, uye kutonhora.

PDC nozzles yekutyoka kwedombo: Inowanzo gadzirwa nehombe caliber uye yakakwirira kuyerera. Vanopwanya maumbirwo ematombo kuburikidza ne-high-pressure fluid impact uye vakakodzera kuchera mudombo rakaoma uye dense rock formations.

PDC nozzles yekuchenesa dombo: Tarisa pakugadzirisa kuyerera kwemunda kugovera kuti uve nechokwadi chekuti matombo ekucheka anotakurwa pasi nenguva. Iwo anowanzo shandiswa muakapfava maumbirwo kana tsime zvikamu zvinokarirwa kuyera.

PDC nozzles yekutonhodza: Kuburikidza neyakajeka kuyerera dhizaini dhizaini, ivo vanoendesa nenzira kwayo mvura inotonhorera kunzvimbo yekushanda yedhiri, ichidzikisa tembiricha yekushanda yePDC compact uye kurebesa hupenyu hwesevhisi yechibhorani. Iwo anonyanya kushandiswa mumatsime akadzika ekupisa kana kwenguva refu inoenderera mberi yekuchera.

3. Kuronga Nezvinhu

Mukuwedzera, zvichienderana nekusiyana kwezvinhu, PDC nozzles inogona kukamurwa kuva marudzi maviri:yakachena PDC zvinhu uye composite zvinhu zvePDC uye simende carbide.

Pure PDC zvinhu nozzles:Iva nekuomarara kwakanyanya uye kwakaringana kupfeka kuramba, kwakakodzera kune yakanyanya kuoma nzvimbo dzekuchera.

Composite zvinhu nozzles:Nepo vachiona kusamira, ivo vanoderedza mitengo yekugadzira uye vakakodzera kune yakajairwa kudhiraivha mamiriro ekushanda.

Mumashandisirwo anoshanda, zvinodikanwa kusarudza zvine musoro mhando yePDC nozzle zvichibva pazvinhu zvakaita sekudzika kwekuchera, kuoma kwekugadzira, uye rudzi rwemvura kuti uwedzere kushanda zvakanaka kwekuchera uye kukwirisa mitengo. Sezvo kuongorora nekusimudzira oiri kuchienda kune dzakadzika uye dzakaoma maumbirwo, dhizaini yePDC nozzles inogara ichigadzirwa. Mune ramangwana, ivo vanozokura munzira yekuve yakanyanya kusapfeka, inoshanda zvakanyanya, uye yakanyanya kukodzera kune akawanda ekushanda mamiriro, ichipa yakasimba rutsigiro rwehunyanzvi hwekusimudzira oiri uye gasi zviwanikwa.
