Chida chopangira mphero cha API 7-1 Casing Section
Mbiri ya malonda
Chigayo cha gawo ndi mtundu wa chida chotsegulira zenera la chivundikiro chomwe chimaphatikiza ntchito zodula ndi kugaya. Chigayo cha gawo chimalowa mu chivundikirocho pamodzi ndi BHA, ndikudula kaye chivundikirocho pamalo osankhidwa. Chigayocho chikadulidwa kwathunthu, chidzachotsedwa mwachindunji pamalo awa. Chikafika pamlingo winawake, ntchito yotsegulira zenera la chivundikirocho imamalizidwa. Chigayo cha gawo chili ndi ubwino wosavuta, ntchito yosavuta kuti chikhale chida chothandiza kwambiri chotsegulira zenera la chivundikirocho.
Pakadali pano, mphero yopangira magawo imatha kufinya ndi kulowetsa simenti mu ntchito yosiya chitsime, zomwe zingapangitse simenti kukhudzana mwachindunji ndi kapangidwe kake patali mkati mwa madigiri 360. Simentiyo imatha kulowa m'chitsime malinga ndi ma porosity ndi kusweka kwa kapangidwe kake, ndipo zotsatira zake zimakhala bwino kwambiri kuposa kufinya simenti pambuyo pobowola.
Mfundo yogwirira ntchito
Pambuyo poti mphero ya gawo yatsitsidwa pamalo osankhidwa mu casing pamodzi ndi BHA, yambani tebulo lozungulira, yatsani pampu, pisitoni yomwe ili mu chida imakankhidwira pansi ndi kupanikizika, pisitoni yotsika imakankhira masamba odulira kutsegula ndikukonza dzenje lotseguka. Masamba odulira akatsegulidwa mpaka kukula kwakukulu, kukonza dzenje lotseguka kumatha. Pansi pa kupanikizika kosalekeza kwa pampu, tsamba likhoza kutsegulidwa ndikusinthidwa dzenje mwachindunji. Pambuyo poti pampu yayimitsidwa, pisitoni imabwezeretsedwanso pansi pa ntchito ya kasupe ndipo masamba odulira adzabwezedwa okha.
Zinthu zomwe zili mu malonda
(1) Kapangidwe ka makina, kapangidwe kosavuta komanso ntchito yosavuta
(2) Kuthamanga kochepa koyambira ndi mphamvu yayikulu yothandizira tsamba zimathandiza kudula chivundikiro;
(3) Kapangidwe ka masika amphamvu kwambiri kamathandiza kubweza choduliracho chokha mutadula;
(4) Kapangidwe ka stop block ndi pin kumathandiza kukakamiza chida kuti chibwezeretsedwe;
(5) Tsambali lili ndi kukula kwakukulu ndipo lingagwiritsidwe ntchito pa chivundikiro chomwecho chokhala ndi makulidwe osiyanasiyana a khoma;
(6) Tsambali limapangidwa ndi tungsten carbide yapamwamba kwambiri ndipo Bake hughes ndi njira yofanana yowotcherera, yokhala ndi ntchito yodula bwino komanso nthawi yayitali yogwirira ntchito.
Tebulo la Kukula kwa mphero la Gawo
Zipangizo zofananira - Mphero yapamwamba kwambiri yopangira zinthu
Zipangizo zopukusira zonse zimapangidwa ndi tungsten carbide alloy yapamwamba kwambiri ndipo Baker Hughes ali ndi ukadaulo womwewo wopukusira. Cholinga cha mndandanda wa mpherozi ndikubwezeretsa kwathunthu kusankha zinthu, kapangidwe ka kapangidwe kake, ndi njira yopukusira ya Baker Hughes, kuti akwaniritse mtundu womwewo wa Baker Hughes.
2. Mbiri yapamwamba kwambiri ya mphero yamagetsi
Chitsulo chapamwamba kwambiri chingathe kupanga mphero yofewa kwambiri yokhala ndi mainchesi akunja a 76 mm mpaka 445 mm. Chitsulo chapamwamba kwambiri chimagwiritsidwa ntchito ngati chitoliro chachikulu, zomwe zimathandiza kukonza mabowo akuluakulu amadzi kuti zinyalala za mphero zituluke bwino. Nthawi yomweyo, malinga ndi zosowa za makasitomala, kapangidwe ka chinthucho kangapangidwe kuti kagwiritsidwe ntchito bwino kwambiri.
3. Tebulo la Kukula kwa mphero ya Taper
Kapangidwe ka malonda
1. Mphero ya gawo ili makamaka ili ndi zigawo izi: cholumikizira chapamwamba, thupi lalikulu, pisitoni, nozzle, masamba odulira ndi kondomu yotsogolera, ndi zina zotero.
III. Ubwino waukadaulo wa mphero ya Petrozhr
1. Yopangidwa ndi tungsten carbide yapamwamba kwambiri
Masamba a mphero opangidwa ndi kampani yathu ali ndi ubwino wotsatira:
(1) Ntchito zopera ndi kudula zimakhala zachangu kuposa masamba wamba;
(2) Chepetsani mphamvu yobowola yomwe imafunika podula;
(3) Zilonda za mano ndi zofanana ndipo palibe malo otsetsereka omwe amapangidwa;
(4) Zinyalala zomwe zimapangidwa zimakhala zofanana kwambiri;
(5) Kulimba kwa zipangizo zopangira n’kokwera ndipo kapangidwe kake n’koyenera. Pogwira ntchito, amadula chitsulo m’malo mopera chitsulo.
2. Kuyang'anira zinthu zoyambira
Kabodi ya tungsten yomwe yasankhidwa ndi kampani yathu idzatumizidwa ku bungwe loyesa akatswiri kuti akayang'anire gulu lililonse likafika. Kuti zitsimikizire kuti kuuma kwa alloy ndi zizindikiro zina zikukwaniritsa zofunikira za kampani yopanga.
3. Wangwiro ndondomeko kuwotcherera
Timagwiritsa ntchito katswiri wakale wa Baker Hughes wowotcherera ndipo timasankha zida zowotcherera zomwezo ndi zipangizo zina zothandizira mu workshop ya Baker Hughes kuti tipeze njira yopangiranso ukadaulo wa Becker wowotcherera pogwiritsa ntchito zipangizo ndi makina.
Pofuna kuchepetsa kusintha kwa zida chifukwa cha kusintha kwa kutentha isanayambe komanso itatha kuwotcherera, timakhazikitsa njira yotetezera kuwotcherera kuti titsimikizire kukhazikika kwa mawonekedwe azinthu ndi magwiridwe antchito.
Njira yogwirira ntchito ya mphero ya IV.Section
Kukonzekera dzenje:
1. Konzani chivundikiro. Konzani chivundikiro cha pansi pogwiritsa ntchito mphero ya taper kapena chopangira chivundikiro.
2. Kuyeretsa Zitsime. Tsukani mafuta osakonzedwa kapena zakumwa zina kuchokera m'chitsime ndi madzi oyera.
3. Kukwecha chivundikiro kapena chitsime. Kukwecha ndi kukoka mapaipi kuyenera kuchitika ndi chikwapu chokhazikika ndi m'mimba mwake wokoka mpaka mamita 20 pansi pa malo opukutira gawo.
4. Konzani madzi opera. Makhalidwe ake osiyanasiyana angathandize kuti zinyalala zisamayende bwino.
Kuyesa pansi:
1. Yesani kudalirika kwa zida;
2. Kusintha kwa kuthamanga kwa pampu kumayesedwa pamene masamba odulira atsegulidwa, zomwe zimapangitsa kuti pakhale maziko oweruza ngati chivundikiro cha pansi chadulidwa kwathunthu.
Kusankha malo opukutira:
1. Simenti yomwe ili kunja kwa chivundikiro cha mphero iyenera kupakidwa simenti bwino.
2. Pewani malo omwe chivundikirocho chili ndi kusokonekera komanso kusokonekera. Ngati pali malo otere, ntchitoyo iyenera kuchitika mamita 30-40 kuchokera pamalowo. Ndipo poyambira ntchito yodula iyenera kukhala mamita 1-3 kuchokera pamalo olumikizirana apafupi.
3. Thumba liyenera kusungidwa pansi pa shaft. Nthawi zambiri, kutalika kwa thumba kuyenera kupitirira 100m.
Kudula chivundikiro:
① Mukalumikiza chidacho mu BHA ndikuchiyendetsa mpaka pamalo a mphero, yambani tebulo lozungulira kuti mudziwe malo olumikizirana a casing malinga ndi mbiri ya casing (kulemba), ndikutsitsa chidacho pafupifupi 1-3m pamwamba pa coupling ndi brake yapafupi.
② Yambani tebulo lozungulira poyamba, onjezerani liwiro lozungulira kufika pa 50-60r / min, yambani pampu, pang'onopang'ono onjezerani kusuntha, kuti kuthamanga kwa pampu kukwere. Panthawiyi, kuthamanga kwa pampu kumawonjezeka kuyambira kakang'ono mpaka kwakukulu, pang'onopang'ono kumawonjezeka kufika pa 10-12mpa.
③ Pitirizani kudula chivundikirocho kwa mphindi 20-45. Pamene mphamvu ya pampu yatsika mwadzidzidzi ndi 2-5mpa, chivundikirocho chimadulidwa. Kuti thupi la chodulira litseguke bwino, sungani malo odulirawo pamalo awa kwa mphindi 30 mutadula, ndipo pang'onopang'ono onjezerani kusuntha kuti muwonetsetse kuti kusweka kwasweka kwapangidwa mokwanira.
Chikwama chopukusira:
WOB ikhoza kuwonjezeredwa pang'onopang'ono pambuyo poti chivundikirocho chadulidwa. chomwe chimayendetsedwa pakati pa 10-25kn, liwiro lozungulira limawonjezeka kufika pa 80-120r / min, ndipo kuthamanga kwa pampu kumayendetsedwa mkati mwa 10MPa kuti zitsimikizire kuti kusuntha kozungulira kumatha kunyamula zinyalala zachitsulo. Gawo lililonse likafika pafupifupi 0.5m, likhoza kubooledwa 1m kuti liziyenda bwino komanso kuzungulira, kuti zinyalala zachitsulo zomwe zaphwanyidwa kuchokera ku gawolo zibwerere bwino kudzera mu annulus. Pambuyo pa kuzungulira kwa 1-2, booleraninso kuti mupitirize kupanga ndi kugaya.
[Panthawiyi, ndikofunikira kusintha bwino momwe matope amagwirira ntchito pamene mukuwonjezera kusuntha; nthawi yomweyo, sunthani bwino chida chobowolera ndikusintha kayendedwe ka madzi kuti chitsulo chibwerere bwino ndikuletsa zinyalala kusonkhana]
