Zvinhu Zvinokanganisa Hunhu uye Kumhanya Kwekubhowa

1. Sezvo kumhanya kwekubiridzira kwecompound bit kuri kaviri kupfuura giya rechipiri remuchina wekuboorera, uye kuri kanenge kane giya rekutanga, zviri nyore kuwedzera ROP zvakanyanya.

2. Kumhanya kwakanyanya kwekutenderera kwekuchera kwakabatana kwakakodzera hunhu hwekucheka kwePDC bit pakuumbwa kweshear.

3. Nzira yekufamba kwemvura iri muWellbore yakatsetseka. Kubatanidza kuchera kwakanangana nekwakatsetseka nekudhonza kunotsvedza kuti kuchinjwe nguva nenguva, zviri nyore kudzora kona yemakumbo uye kuona kuti gomba riri pasi rakachengeteka.

4. Chimiro chezvishandiso zvekuboorera chinonyatso nyoreswa. Panguva yekuboorera kwakabatana, kumanikidzwa kwekuboorera kunowanzova <100-120kN, uye zvinodiwa pakuboorera zvinogona kuitwa nekokora shoma kana kuti pasina, uye mukana wekunamira unodzikira zvikuru.

5. PDC drill bit inoshanda zvakanyanya inoshanda pamwe chete nechishandiso chekugadzira matsime, izvo zvinodzivirira kutadza kushanda kwebearing yekoni nekukurumidza uye hazvikonzeri tsaona dzekurasikirwa nekoni.

Kupesvedzera kweMaparameter eKuboorera paKumhanya Kwemhando Yekuboorera

Munguva yekuboora, simba rema parameter ekuboora pakati pezvinhu zvinodzorwa pakumhanya kwekuboora harigone kufuratirwa, zvakaita se: rudzi rwe bit, dhayamita ye bit nozzle, simba remvura ye bit, bit pressure, speed, pombi pressure, displacement, nezvimwewo. Kana paine mamwe mamiriro ezvinhu akakosha, ROP inowanzo wedzerwa nekudzora pressure yekuboora, rotational speed, pombi pressure uye displacement.

Simba reKuchera Mvura paHunhu uye Kumhanya kweKuchera

Mvura yekuboora iropa rekuchera, saka mashandiro emvura yekuboora akakosha zvikuru pakuboora. Zvinhu zvikuru zvinokanganisa ROP ndiko kusimba kwemvura yekuboora, huwandu hwemvura yekuboora uye huwandu hwakasimba huri mumvura yekuboora. Tichifunga kuti mushonga unoshandiswa muhurongwa hwemvura yemugodhi wakadzika uripo wakapfuma muma chromium ions nemamwe ma heavy metal ions ane simba guru panharaunda, zvinokurudzirwa kudzidza nekushandisa hurongwa hwemvura yekuboora wakadzika hune hushamwari nenharaunda kuti uvandudze sisitimu yemvura yekuboora ye silicate iri kushandiswa pari zvino munzvimbo diki muChina. Sisitimu yekuboora yakagadzirwa kuti igadzire nhevedzano yemvura yekuboora yekudzivirira nharaunda yakakodzera mamiriro e geological uye engineering enzvimbo yega yega yekuboora.
