CFA yinqwaba. incazelo

CFA yinqwaba ngokuvamile asetshenziselwa ukuthola ngezizathu ezakhiweni othola ukuvuselela. Wide ngokwanele ukuzisebenzisa ngenxa izici eziningana. Okokuqala, CFA yinqwaba babe Ubukhulu encane nge ekhethekile amakhono obuchwepheshe izicelo. Lezi imiklamo akuvumela ukusebenza amakamelo obude - phezulu ngamamitha amabili, isibhakela imbobo ngokusebenzisa wokwakha, kwagcizelela ukhonkolo, kwagcizelela ukhonkolo kuze kube amamilimitha angu angamakhulu amathathu ubukhulu, futhi amamitha angu amahlanu ukujula. ukufakwa Compact angafeza imishini egumbini sise ngaphandle kwe-amandla iyunithi.

CFA yinqwaba babe ezihlukahlukene. Olunye uhlobo lokudla ukwakhiwa asetshenziswa izakhiwo ezintsha ukuze aqinise izindonga diaphragm kanye ezicijile for nemithambeka mpo. Zibizwa ngokuthi "umjovo amahange." Kulokhu, sebenzisa uhlelo olukhethekile okubambelela.

Kuye izimo inhlabathi owakhetha yanoma yisiphi esinye ithuluzi for imishini. CFA yinqwaba kokuba obuphelele kanye ububanzi ngokuhambisana predetermined umthwalo esindayo nomthamo yinqwaba noma ihange beqonda umzamo.

Drilling emhlabathini engazinzile waphuzisa ngokugeza imithombo Kwenziwa usebenzisa slurry noma usebenzisa bezinhlamvu.

Iinsetjenziswa yinqwaba nesithukuthezi Kwenziwa usebenzisa ukugcizelela. Ngakho, ngokuhambisana ubunjalo ukuqinisa esebenza umthwalo kwenziwa ubude lonke noma phezulu. Ubude kwesigaba ukuqinisa kunqunywa ngokuhambisana ukuphakama egumbini. Ukuqinisa setha emva, ngaphambi noma ngesikhathi test yokucindezela kahle.

Iinsetjenziswa inqwaba izisekelo kusikisela ukulungisa izingxenye inqwaba ngokugxilisa phansi komhlaba bese egcinwa ukunikeza ukushuba ezidingekayo ungqimba ayisivikelo ukhonkolo. Nge emalungeni eziphothene kuqinisekiswa kwakwakhe isidumbu ukuqinisa ubude futhi, ngokufanelekile, iyunifomu amandla ukuqinisa. I nentaba inqwaba okungenani ububanzi induku ngokufanele izinduku. Ngokuvamile, indawo cross-Sectional ku ukuqinisa longitudinal akuyona esingaphansi 0.5% endaweni cross-Sectional inqwaba uqobo.

Ukuze uthuthukise inqwaba yenethiwekhi izici, ngenxa compaction, wenziwa crimping ezindongeni kahle futhi asanda wathela ukhonkolo.

Ingcindezi ukuhlolwa kungenziwa ngezindlela ezihlukahlukene.

Ngakho, kusho ukuthi ifayela elandwayo singase sithwale ingxenye eyengeziwe of futha uketshezi ngokusebenzisa Tampon okuyinto decompresses le wellhead, a wellhead noma ekhona ipayipi isizinda. Kulokhu, ngethonya wenziwa esikhungweni ukucindezela 0.2-0.3 MPA imizuzu emibili. Uma ingcindezi ukubambelela phakathi nalesi sikhathi akunakwenzeka, umsebenzi wenziwa emva kwehora noma amabili, kuze kube yi oyifunayo eyatholakala.

Ukuhlolwa ingcindezi kungase kubangele kwi sigaba esithile inqwaba noma ezansi kahle ngokusebenzisa ngezikulufo bushing.

Imisebenzi abazenzi nokusetshenziswa ubuchwepheshe electro. Uma lokhu sekwenziwe downhole crimping electrohydrodynamic noma izindonga.

Enye indlela iwukuba 'kabusha umjovo ". Kulokhu, udini kwenziwa endaweni ethile inqwaba esebenzisa umjovo emgqonyeni discontinuity ukumnika eyinhloko ukhonkolo.

CFA yinqwaba ahlelwe ngokuhambisana ethile inqubo umjikelezo ehlanganisa imisebenzi eziningana:

1. Drilling.
2. Inhlangano ifreyimu kwagcizelela.
3. imbobo Ukugcwalisa we ukhonkolo (okukhokhwayo) ingxube.
4. Crimping ingxube fresh.

Kufanele ukuthi uzimele kwagcizelela esivunyelwe nguMthetho ukuba efakwe njengenhlangano ngemva futhi ngaphambi kokugcwalisa emgodini nenye.

Muva nje, kukhona ngcono njalo imishini, inqubo izinyathelo namasu Akungabazeki ukuthi okuhloswe ngazo ukuthuthukisa izinga kanye nomthamo yinqwaba izithelo.
