Mukukura kuri kuenderera mberi kwekudiwa kwezviwanikwa zvepasirese, midziyo yemigodhi inoshanda uye yakagadzikana yave yakakosha pakuona simba nezvicherwa. Polycrystalline diamond compact (PDC) cutters, nekuita kwavo kwepamusoro, zvishoma nezvishoma vari kutsiva echinyakare carbide cutters sechinhu chakakosha mukubvisa zviwanikwa. Kukosha kwavo kwepakati kuri mumatanho matatu akakosha: kubudirira kwetekinoroji, kushandiswa-chaiyo kuchinjika, uye hunyanzvi hwekuvandudza.

Kubva pakuona kwehunyanzvi, PDC cutters vakawana quantum leap mukuoma uye kupfeka kuramba. Yakagadzirwa pasi pekupisa kwakanyanya uye kudzvanywa kwedhaimondi micro poda uye carbide substrate, vanogara nhaka yekuoma-kwepamusoro kwedhaimondi (kupfuura HV10,000) vachichengeta kuomarara kwecarbide. Izvi zvinogadzirisa dambudziko rakatarisana nevacheki vechinyakare: kuomarara kwakanyanya kunotungamira kune brittleness, nepo kuomarara kwakanyanya kunotungamira kupfeka. Mumigodhi yakadzika-shaft, PDC cutters, anoshanda mumatombo akaomarara akadai segranite nebasalt, anoratidza mwero wekupfeka unongori chikamu chimwe chete muzvishanu chevanocheka carbide, vachiwedzera hupenyu hwavo hwebasa ne3-5 nguva. Izvi zvinoderedza zvakanyanya kuwanda kwekutsiviwa kwechikamu pasi pevhu uye zvinoderedza njodzi yekukanganiswa kwemigodhi. Panyaya yekuchinjika, kuwanda kwePDC cutters kunosangana nezvinodiwa zvakasiyana zvekubvisa zviwanikwa. Mukuchera oiri negasi, micheto yavo yakapinza inopwanya nokukurumidza matombo. Maprofiles emazino akasarudzika (akadai seweji nechipunu maumbirwo) anochinjika kune akasiyana matsime emugodhi, achiwedzera kugona kuchera mumatsime akachinjika uye anotungamira neanopfuura 40%. Mumigodhi yemarasha, vanocheka-simba PDC vanocheka vanoshingirira kukanganiswa kwemarasha seam inclusions, kudzivirira kutsemuka kwezino uye kuona kuenderera mberi kwekushanda kwemichina yakanyatsogadzirwa migodhi. Mumigodhi yesimbi, maPDC cutters ane machira asingadziviriri anodzivirira kukukurwa kubva mumvura ine acid yemugodhi, zvichiita kuti ive yakakodzera kune ese akavhurika uye mugodhi wepasi pevhu munzvimbo dzakaoma dze geological.

Kubva pamaonero eindasitiri, vacheki vePDC vakabatsira zvakananga mukudzikisa mutengo uye kuvandudzwa kwehunyanzvi mukubvisa zviwanikwa. Kune rumwe rutivi, hupenyu hwavo hurefu hunoderedza mutengo wekutenga uye kutsiva zvinoshandiswa. Semuenzaniso, mukuchera mafuta, mari yevanocheka patsime inogona kuderedzwa ne20% -30%. Uyezve, kushanda kwavo kwakanaka kwekucheka kunopfupisa kutenderera kwemigodhi. Semuenzaniso, mushure mekutora maPDC cutters, mugodhi mukuru wemarasha wakawedzera mifananidzo yemazuva ese evaveuri kubva pamamita makumi masere kusvika pagumi nemakumi maviri, zvichiwedzera huwandu hwekugadzira pagore ne15%. Uyezve, iyo yakaderera-yekupfeka zvivakwa zvePDC cutters inoderedza kugadzirwa kwekucheka uye kurerutsa kuedza kwekuchenesa gole, zvisina kunanga kuvandudza kuchengetedzeka kwemigodhi.

Sezvo kudhirowa kwezviwanikwa kunowedzera zvakadzika uye mune mamwe maumbirwo akaomarara, shanduko yetekinoroji yePDC cutters inoramba ichiwedzera. Mune ramangwana, nekusimudzira kupikisa kwepamusoro-soro kuburikidza ne-nano-coating tekinoroji uye nekugadzirisa iyo yekucheka chimiro kuburikidza ne3D kudhinda, PDC cutters ichawedzera kukurira mabhodhoro ekuita, ichipa rutsigiro rwakasimba mukuvandudza kwezvakaoma-kubvisa zviwanikwa senge shale gasi uye yakadzika-mugungwa zvicherwa, uye nekuwedzera kusimbisa chinzvimbo chavo chakakosha mukubvisa zviwanikwa.
