Ubwoko butandukanye bwo gucukura no gucukura neza

Ubwoko butandukanye bwo gucukura amabuye y'agaciro kandi neza

Ubucukuzi bw'amabuye y'agaciro hamwe no gucukura neza ni umwobo urambiranye ucukamo kandi winjira mu bikoresho byoroshye kandi bikomeye. Zikoreshwa mu bucukuzi bw'amabuye y'agaciro, gucukura neza, gucukura amabuye, gucukura, kubaka, gushakisha geologiya, no guturika.

Ubucukuzi bw'amabuye y'agaciro hamwe no gucukura neza mubisanzwe birahuza umurongo uhuza umugozi hamwe numubiri wuzuye unyuzamo amazi ya drill. Amazi ya drill arasabwa gukuraho ibice byimyitozo, gukonjesha gato, no guhagarika urukuta rwa bore. Ubwoko bwo gucukura neza burimo ibi bikurikira:

Tri-cone cyangwa bitskirimo imitsi itatu yinyo, buri kimwe gifite inguni yikinyamakuru cyerekejwe kuri biti yibanze. Inguni yikinyamakuru yahinduwe ukurikije ubukana bwimikorere. Amenyo ya buri cone arashishanya kugirango arwane mu isi ikomeye. Bito itwarwa nuburemere-kuri-bit (WOB) mugihe ikururwa nigikorwa cyo kuzenguruka cyumutwe wa biti.

Hasi-umwobo (DTH) inyundo bitszikoreshwa hamwe Hasi-umwobo inyundo zo gucukura umwobo unyuze muburyo butandukanye bwamabuye. Hamwe na DTH inyundo, bits ya nyundo bitsindagirizwa hamwe na disikuru ihindagurika yo kuzunguruka bito mu butaka. DTH bits ni bits-umutwe bits ifite conic cyangwa chisel bit yinjizwamo ihujwe na matrix hafi yumutwe wa biti. Iboneza umutwe wa biti irashobora kuba convex, yegeranye, cyangwa iringaniye.

PDC bitshamwe na polycrystalline diamant compact (PDC) yinjizwamo ishobora kwitwa PDC bits. Bitandukanye na tricone, bits ya PDC nigice kimwe cyimibiri idafite ibice byimuka kandi byakozwe kugeza igihe; buri kintu cyateguwe munzu kugirango ikore, ihamye kandi yiringirwa. Hitamo Matrix cyangwa ibyuma-bikomeye cyane kugirango uhuze porogaramu zitandukanye.

Utubutoni kimwe na DTH bits itunganijwe-umutwe bits ifite conic cyangwa chisel biti byinjijwe bihujwe muri matrix hafi yumutwe wa biti. Iboneza imitwe ya biti irashobora kuba convex, yegeranye, cyangwa iringaniye. Utubuto bito ni impande zose zibereye kubutare bukomeye, hejuru yo gucukura inyundo.

Bits bits na chisel bitsni imitwe-imitwe ikomye ibyuma cyangwa karbide. Chisel bits isobanurwa nicyuma kimwe mugihe ibice byambukiranya birimo ibyuma bibiri cyangwa byinshi byambukiranya hagati ya biti. Ubusanzwe ibyuma bifatanyirizwa hasi hejuru yubutaka.
