Mapulagi ebhiriji anogona kubvisika here kutsiva mapulagi ebhiriji akajairwa?

Parizvino, tekinoroji yekutsemura tsime rave chishandiso chakakosha chekugadzirisa dhamu uye nekuwedzera kugadzirwa kwetsime rimwe chete. Seimwe yezvishandiso zvakakosha zvekutsemuka, mabhiriji plugs ari kuwedzera kushandiswa zvakanyanya. Parizvino, mapulagi ebhiriji akajairwa anosanganisira maplugs ebhiriji anodhirika uye mapulagi makuru edhayamita ebhiriji. Drillable bridge plugs inokonzeresa tsaona dzemugomba uye kushanda kwakakwirira nemitengo yekuvaka panguva yekugaya maturusi ekuchera mushure mekutsemuka, ukuwo marara uye mvura yekushandisa zviri nyore kusvibisa dura.

Muviri mukuru weiyo dissovable bhiriji plug inogadzirwa neyakareruka uye yakakwirira-simba dissovablealloy zvinhu zvine simba rakawanda, kumanikidza kuramba kwe70 MPa, dissovablein mvura, uye inodzoreka kunyungudika nguva. Mushure mekutsemuka, chivharo chebhiriji chinonyungudika chinopindirana nemvura iri mugomba pasi petembiricha yakakwira uye nekumanikidzwa kukuru, inonyunguduka uye yoburitswa mugomba nemvura inoyerera. Kugadzirwa kwechishandiso ichi kudzoreredza kwakazara kwechinyakare bhiriji plug fracturing chishandiso.

Mutengo wekunyungudika bhiriji plugs wakangofanana neanobva kunze kwenyika anoumbwa mabhiriji mapulagi, asi nzira yekutevera yemapulagi echinyakare mabhiriji akareba uye anodhura, nepo kushandiswa kwemapulagi ebhiriji anonyungudika kunogona kudzikisa zvakanyanya mutengo wepashure pekuvaka kwekutsemuka. mabasa. Dissolvable bhiriji plugs anogona kudzikisira mukana wekugara pakati pekutsemuka, uye kunyangwe bhiriji plug rikavharwa, rinogona kunyungudika kuburikidza nekukurumidza kurapwa tekinoroji, nokudaro kuderedza njodzi yekuwedzeredza plug yebhiriji.
