Isimiso kanye nendlela yokusebenza ye-perforation yokubeka kazibuthe

Ngokwezidingo zohlelo lokuthuthukisa, ukubhoboza imbobo kuwukusebenzisa isibhobo esikhethekile somthombo kawoyela ukuze singene odongeni lwebhokisi kanye nomgoqo wendandatho kasimende wongqimba oluqondiwe ukuze kwakheke imbobo yokuxhuma phakathi kongqimba oluqondiwe kanye nomthombo webhokisi. Ngakho-ke, ukubhoboza kuyisinyathelo esibalulekile sokuthuthukiswa kwendawo kawoyela kanye nezindlela ezibalulekile zokukhiqiza uwoyela, igesi namanzi.

1.umgomo wokusebenza we-positioner kazibuthe

Kuyaziwa kusukela emthethweni wokungeniswa kukazibuthe ukuthi uma uzibuthe noma ikhoyili inyakaza okuhlobene, ukugeleza kazibuthe kobukhulu.

inkambu ye-etic ezungeze ikhoyili iyashintsha, intambo kazibuthe isika ukuphenduka kwekhoyili futhi ikhiqize amandla akhona kanye namandla asetshenziswayo, ikhoyili ayiyona iluphu, ayikho i-current induced, amandla akhangiwe kuphela akhona. Isimo esiyisisekelo sokungeniswa kukazibuthe ikhoyili kazibuthe yokusikwa kwentambo kazibuthe ezungeze ikhoyili, futhi ukwenza ikhoyili yokusika intambo kazibuthe, ukugeleza kazibuthe kwenkundla kazibuthe ezungeze ikhoyili kufanele kushintshwe. Okusho ukuthi, uzibuthe kanye nekhoyili kusekunyakazeni okuhlobene, kodwa ukwakheka kwesimo kazibuthe asikuvumeli uzibuthe kanye nekhoyili ukuthi ihambisane nokunyakaza, khona-ke i-flux kazibuthe ezungeze ikhoyili ngeke ishintshe, futhi ngeke ikhiqize. amandla okungeniswa, ukuze sikwazi ukusebenzisa olunye uhlobo loshintsho oluguquguqukayo lukazibuthe, okungukuthi, ukuthembela ekushintsheni kwezinto zangaphandle ze-ferromagnetic. Amandla adaliwe akhiqizwa into yangaphandle ye-ferromagnetic ethinta indawo yayo kazibuthe abonisa izinguquko endaweni yangaphandle. Ngakho-ke, lapho indawo kazibuthe itshuza kukhola ku-casing, ukusatshalaliswa komugqa wensimu kazibuthe kuyashintsha ngenxa yokushintsha kogqinsi lwezinto zangaphandle ze-ferromagnetic - udonga lwe-casing, ukuze amandla okungenisa enziwe ngokusika ikhoyili. Lapho i-waveform yesignali ye-magnetic locator irekhodwa endaweni engaphezulu, kuzonqunywa ukuthi indawo kazibuthe idlula kukhola ekujuleni okuthile emthonjeni. Ngakho-ke, ingakwazi ukuxhumana nengxenye ejulile yensimbi yomhlabathi ukuze iqedele umsebenzi wokuma kwe-perforation.

2.Thobela izinqubo zokusebenza zesayithi lokubhoboza

(1) Bulala kahle ngokwezidingo zohlelo lokuklama.

(2) Lungisa okokusebenza nokufakwa komthomboamathuluzi okulungiselela ngempumelelo ukuvimbela ukuqhuma.

(3) Ngaphambi kokubhoboza, i-casing kufanele idlulengomthombo ngokwemithethonqubo, ukugeza isihlabathi umthombo kuze kufike phansi okwenziwa emthonjeni.

(4) Ingcindezi ye-casing kumele ihlolwe futhi coigcwaliswe ngaphambi kokuthi kubhodlozwe umthombo omusha.

(5) Iphutha lokujula kokubhoboza sihholo akufanele libe ngaphezu kuka-0.1m.

(6) Uma imitha yokubhoboza ingaphezu kwama-3m,umthombo ungagcwaliswa kuphela ngemva kokugezwa kwentambo yepayipi.

(7) Umthombo kajeyini kumele uhlolwe angemva kokubhoboza, ivolumu ye-extrusion inkulu kuno-1m³, ingcindezi ye-extrusion ingaphansi kuka-15MPa, futhi isikhathi sokukhipha asikho ngaphansi kuka-5min.

(8) Ngesikhathi sokubhoboza,kufanele kube nomuntu okhethekile ozonakekela i-wellhead, avimbele izinto eziwayo, futhi anake ukuthi kukhona ukuboniswa kwamafutha negesi. Uma kutholakala ukuchichima, ukubhoboza kufanele kumiswe, intambo yepayipi kufanele ibanjwe ngokushesha, futhi ukucindezela kwekholomu ye-liquid kufanele kulungiswe ngaphambi kokubhoboza.

(9) Enqubweni ye-cannonball, umakukhona ukumelana, ungabi nzima, kumele abeke phambili i-cannonball, futhi athathe izinyathelo ezihambisanayo ngemva kokufunda isimo esingaphansi komhlaba.

(10) Phakathi nakho konke ukwakhiwainqubo, ithimba labasebenza kanzima kufanele lisebenzisane eduze nethimba elibhobozayo ukuze likwazi ukubhobozwa ngokuphephile, futhi azikho iziqhumane ezivunyelwe ukuzungeza umthombo.

(11) Ukuqoqwa kwedatha yokubhobozwa:

① Buyekeza ukwakhiwa kokubhoboza cards;

② Kala ukuminyana koketshezi lokubulala;

③ Indlela yokubhoboza kokubili isibhamupe;

④ Vula ukwakheka, isikhawu kahle, inombolo holes, emissivity;

⑤ Yini eboniswa ngemva kokubhobozwa;

⑥ Isikhathi sokubhoboza nokuhleleka kokusebenza;

⑦ Ezinye izimo ezikhethekile.
