CFA murwi. tsananguro

CFA murwi kazhinji kushandiswa kuwana chikonzero mukuvaka achirapwa gadziridzo. Wide zvakakwana kuzvishandisa nokuda zvinoverengeka. Chokutanga, CFA murwi vane diki kukura chaizvo hwokugadzira nezvaanogona kuita mafomu. mazano aya kukubvumira kushanda mumakamuri ane kureba - kusvika mamita maviri, punching gomba kubudikidza masonry, zvakasimbisa kongiri, zvakasimbisa kongiri kusvika millimeters mazana matatu dhayamita uye kudzika mashanu mamita. Compact kugadzwa vangaita kuchera mukamuri riri kunze simba chikwata.

CFA murwi vane-siyana. Imwe mhando kuvakwa zvinoshandiswa zvivako zvitsva kusimbisa diaphragm masvingo uye fenzi kuti tote dzakatenuka. Vari kunzi "jekiseni zvimiso." Muchiitiko chino, shandisa anokosha yakanyatsoti hurongwa.

Zvichienderana ivhu mamiriro akaita kusarudza mumwe Chinoshandiswa kuchera. CFA murwi ane kureba uye dhayamita maererano akafanorongerwa mutoro-kubereka vanokwanisa yemamota kana Mbambo akaziva kuedza.

Drilling mune kusagadzikana pasi uye mvura nokugeza matsime rinoitwa kushandisa slurry kana uchishandisa casing.

Midziyo kufinhikana inoungana rinoitwa vachishandisa chisimbiso. Saka, maererano yezvakaita chisimbiso kuita mutoro rinoitwa pasi rose urefu kana pamusoro. Kureba chisimbiso chikamu kunotemwa zvinoenderana kukwirira mukamuri. Chisimbiso wakaiswa pashure, pamberi kana panguva nevezera bvunzo patsime.

Midziyo nuolet nheyo presupposes kugadzira zvinoumba murwi kuvakira Houses to Rent uye kupa zvakakodzera pakukora runodzivirira rukoko yacho kongiri. With welded majoini kunosimbiswa remubatanidzwa chitunha chisimbiso pakureba uye, naizvozvovo, dzakafanana simba chisimbiso. The gandiwa pakati nemurwi zvichida dhayamita wetsvimbo vanoda pematanda. Kazhinji, muchinjikwa-sectional nharaunda iri longitudinal chisimbiso haidereri pane 0.5% muchinjikwa-sectional nzvimbo pamurwi pachayo.

Kugonesa nemurwi inotakura unhu, nokuda compaction, rinoitwa crimping madziro tsime uye dzichangobva akadurura kongiri.

Pressure kunovhenekwa zvinogona kuitwa nenzira dzakasiyana-siyana.

Saka, dhanilodhi anogona kutakura zvimwe chikamu pombi mvura kuburikidza tampon iyo decompresses ari wellhead, mumwe wellhead kana huripo mutopota chawo. Panyaya iyi, Kuumbwa rinoitwa panguva kumanikidzwa 0.2-0.3 MPa kwemaminitsi maviri. Kana akabata kufurirwa panguva ino hazvibviri, basa rinoitwa zvakare pashure kweawa kana mbiri, kusvikira zvinodiwa mugumisiro inotengwa.

The kumanikidzwa bvunzo anogonawo pasangano chikamu chimwe kubva nemurwi kana kuti pasi patsime kubudikidza the bushing screws.

Mabasa vakatakudzwa kubva nokushandiswa Electro rwokugadzira. Kana izvi zvaitwa downhole electrohydrodynamic crimping kana masvingo.

Chimwe nzira kuti "kunenge jekiseni". Muchiitiko chino, Kuumbwa rinoitwa pasi chimwe chikamu nemurwi kuburikidza jekiseni dhiramu discontinuity chepuraimari aizomupa kongiri.

CFA murwi zvakarongwa maererano imwe muitiro kutenderera zvinosanganisira remapazi akawanda:

1. Drilling.
2. Organization zvakasimbisa pamatanda.
3. Achizadza buri pamusoro kongiri (fines) nezvakasanganiswa.
4. Crimping yakachena nezvakasanganiswa.

Zvinofanira akati kuti zvakasimbisa puranga Unotenderwa iiswe ive pashure uye asati rokuzadza hole musanganiswa.

Munguva ichangopfuura, pane kuramba kuvandudzika pakati midziyo, muitiro matanho uye unyanzvi kuti kunge zvainanga kunatsiridza uye kukwanisa rokupupurira mirwi.
