Zvikonzero zvePDC bit balling

1. Geological zvinhu: iyo stratum inofanira kucheneswa ivhu rakapfava risiri diagenetic muchikamu chepamusoro, chiri nyore kwazvo kunamatira kumusoro kwechibooreso uye chinokonzera bit balling mushure mekusangana; kunyange zvazvo dhaka shale mu stratum iri diagenetic, zviri nyore kunyorovesa uye kupararira, zvichiita kuti tsime remvura Inowanikwa mumatope kana kuti yakasimba chikamu mumatope inowedzera zvakanyanya, iyo inoshambadzirwa pamusoro pechibooreso chekugadzira dhaka; kana maumbirwo acho ane gypsum yakapararira, inokonzeresa kusvibiswa kwedhaka, uye chikamu chinokuvadza chakasimba mumadhaka chinonetsa kubvisa, icho chinowedzera zvakanyanya mukana wekuti chibooreso chiri mudhaka; Pasi pekuita kwekumanikidza musiyano, inotora chinokuvadza chakasimba chikamu mutsime uye kucheka izvo zvisingaitwe nenguva, zvichigadzira keke gobvu rematope, iro rinoungana pasi pePDC bit kana richidonha kuti riite bhegi.

3.Engineering tekinoroji zvinhu: kusimuka panguva yekuchera kudiki, pasi pegomba uye dhiri yekudhiraivha haigone kucheneswa zvinobudirira, uye kukurumidza kwekudzoka kumusoro hakuna kukwana, uye kucheka kunogara mutsime kwenguva yakareba, kunamatira. tsime rusvingo kuumba gobvu dhaka keke, kunyanya pakati uye kumusoro zvikamu. Inonyanya kuipa kana kumhanya kwakakwirira; mune yakapfava madhaka ekuumbwa, iyo yekudhirowa yakakurisa, kuumbwa kana kuchera kuchekwa kunogadzira kusangana kwakananga neiyo drill bit surface, zvichikonzera kubhowa;

4.Drill bit kusarudzwa zvinhu: dhizaini yegomba remvura haigone kusangana nezvinodiwa zvekubvisa chip; iyo chip yekubvisa angle yemugero wekuyerera inodzivirira kucheka kubva pasi petsime zvakanaka.

5. Zviitiko zvehutano hwekushanda: kukurumidza kwekuchera kunonyanya kukurumidza, iyo drill bit haisi kutsvedza pasi pe spiral track, asi ichiramba ichichera dhaka keke kana kucheka pamadziro etsime, izvo zvinogona kukonzera nyore bhegi bhegi; Haisi yekubatanidza kelly kugezesa chibooreso chakatenderedza, asi kudzvanya pasi kana kurovera pasi, uye keke yedhaka kana zvidimbu zvakakweshwa kubva pamadziro etsime zvicharongedza bhiti rekuchera; nzira yekushanda haina kunaka kana ichichera kusvika pasi. , Mushure mekutanga pombi, ichaitawo kuti chibooreso chibhegi; pakuchera mune zvinyoro zvinyoro, chibooreso chichaendeswa zvisina kuenzana.

Kubata kwePDC bit mud bag 

1. Nheyo yekutanga yekubata zviboorero ndeiyi: usamhanye kudhiraivha, nekuti iyo yakawanda yakarongedzwa zviri nani;

2. Pasinei nekudzivirira kana kurapwa kwedhaka bhora, hazvidzivisiki kugadzirisa kushanda kwematope. Kana pane chiratidzo chipi nechipi chemabhora ematope pane chibooreso, kuchera kunofanira kumiswa pakarepo uye mumiririri wekuchenesa anofanira kuiswa mugomba kuti achenese chidimbu chekuchera panguva yekutanga;

3. Misa kuchera, wedzera kusimuka kuti uwedzere hydraulic flushing effect, simudza chibhorani kumusoro kuti usiye pasi pegomba, wedzera kumhanya kwekutenderera uye wedzera simba recentrifugal kuita kuti dhaka rive nyore kukanda kunze, uye kukwira kumusoro. uye pasi nhamba huru yenguva, uye wobva wadzvanya pasi kusvika pasi pegomba pasina kushandura Turntable Cycle kwemaminitsi 5-10, uye dzokorora nzira iri pamusoro; kana isingashande mukati memaseji maviri, unofanirwa kufunga nezvekudhonza kunze kwechibhorani.

Mhinduro ndeye: dzora kuwedzera kwevhu chena risina kuparadzirwa zvakanaka uye asphalt yejuniper paunenge uchishandura uye uchigadzirisa matope, tanga midziyo yakasimba yekudzora munguva kuti ubvise zviduku zvinokuvadza zvakasimba mumatope panguva yekuchera, uye kutsiva PDC bit pakati pekuchera. Displacement circulation inobvisa madhaka anonamira pachibhorani uchiboora nenguva. Mushure mokusvika pasi, tangai kutenderedza nzvimbo yakakura yekutama kwemaminetsi mashoma musati maboora. Kubata aya makiyi ekubatanidza kunogona kudzivirira zvinobudirira iyo PDC bit kubva mukubhegi. Izvo zvakakosha kucherechedza kuti matekinoroji anofanirwa kunyatsonzwisisa kuti iyo pombi yekumanikidza yepipepipe inoumbwa nekutenderera kutenderera uye kudonha kwekudzvanywa kwemhino. Chero bedzi kudonhedzwa kwekumanikidzwa kwenozzle iri zero, zvisinei kuti makomba mangani emvura akaiswa, iyo yekumira yekumanikidza haizokanganisike. Naizvozvo, nekudzikinura ziso, kwete chete vertical pressure haigoni kuchinjwa, asiwo PDC drill bit inowanzokonzerwa nyore kubhegi.

2. Ongorora uye ubate mitemo yekudzora yekutungamira zvakanaka trajectory mune imwe neimwe block nekukurumidza sezvinobvira, gadzirisa iyo yekuchera chishandiso chimiro, uye kuderedza kushandiswa kwePDC kunokonzerwa nekugadzirisa azimuth uye tsime kutsauka pakati. Kana zvichidikanwa kushandisa kuchera mukomboni muchikamu chezasi chetsime nekusadhirowa zvakanaka, Kushandisa yakakwirira-magumo ePDC mabheti ane yakanaka kupfeka kuramba kunogona kuvandudza mashandisiro ePDC mabheti uye kuwedzera kukurumidza kuchera.
