Gwaro Rakakwana reMakirasi ePacker V6-V0 (Chikamu 1): Kunzwisisa Kodhi yeGrading yeDownhole "Sealing Guardians" kubva pamaonero eAPI 11D1 Standard

Mu "nhandare yehondo yepasi pevhu" yekuburitsa mafuta negasi,vapakejindiwo "ma "sealing Guards" anodzivirira kuchengetedzeka kwe "wellboord". Anogona kuparadzanisa kumanikidzwa kwemhando dzakasiyana, kudzivirira kuyerera kwemvura, uye kutsigira tambo dzakatakurwa, zvichishanda sezvishandiso zvikuru zvekuona kugadzikana kwemaitiro ese ekuchera, kupedzisa matsime, uye kugadzirwa kwemafuta. Zvisinei, mamiriro emugomba anosiyana zvakanyanya: mamwe matsime ane tembiricha yemakumi emadhigirii Celsius chete, nepo mamwe achipfuura 200°C; mamwe ane kumanikidzwa kwakagadzikana, nepo mamwe achisangana nekuchinja-chinja kakawanda; mamwe ane mafuta akajairwa, nepo mamwe ane "mhuka" dzinoparadza dzakadai sehydrogen sulfide (H₂S).

API 11D1 Standard yeDownhole Tools muIndasitiri yePetroleum neGasi reMusikirwo - Packers and Bridge Plugs inotsanangura zvakajeka kuti makirasi epacker anowedzera padanho rekushanda kubva paV6 kusvika kuV0: nhamba diki, zvinodiwa pakushanda zvakanyanya. V6 ndiyo "nhanho yekutanga," uye V0 ndiyo "nhanho yekupedzisira yekushanda," nekirasi yega yega inoenderana nemiyero yakajeka yekuedza uye mamiriro anoshanda.

Nhasi, tichakubatsirai kujekesa musiyano mukuru pakati pemakirasi aya manomwe uye kudzivirira mafungiro asiri iwo pakusarudza mapakiti.

Core Logic yeClass Classization mu API 11D1

Vanhu vazhinji vanovhiringidza kurongeka kwemakirasi epacker. Chinhu chikuru chekurangarira ndechekuti dhizaini yekirasi yeAPI 11D1 inotevera musimboti wekuti "kana nhamba diki, kuongorora kwacho kwakazara." Kuwedzera kwemazinga ekirasi kunoreva kuti zvinhu zvekuyedza zvinowedzera zvishoma nezvishoma mamiriro akaomarara (akadai sekutenderera kwekushisa, mitoro yeaxial, kuvharwa kwegasi, uye nharaunda dzinoparadza) kune bvunzo yekutanga iri nyore yekusimbisa static.

Chinangwa chikuru chechikamu ichi ndecheku "kuenzanisa kana uchida" - hazvingodziviriri chete kutambisa mari kunokonzerwa nekushandisa michina yepamusoro-soro mumatsime echinyakare asiwo zvinodzivirira njodzi dzekuchengetedza dzinobva mukushandisa michina yepasi-pasi mumatsime akanyanya.

Kirasi V6: "Varwi veGarrison" vePadanho Rokutanga vane Maitiro Ekutanga Anotsanangurwa Nevagadziri

Zvinoreva zveUnyanzvi

Kirasi V6 ndiyo kirasi yakaderera yekusimbisa dhizaini yevapaki. Nzira dzayo dzekuyedza uye zvinodiwa zvekugamuchira zvinotsanangurwa nevagadziri pachavo. API 11D1 inongotaura chete hurongwa hwekutanga (semuenzaniso, kugadzirisa kuvimbika, kuyedzwa kwemutoro wekuchekwa) uye haina zviratidzo zvekushanda zvakabatana. Nzvimbo yayo huru ndeye "kusangana nezvinodiwa zvekutanga zvekuvhara muzviitiko zvakati nyore."

Mamiriro Ezvinhu Anoshanda Ekushandisa Mutsime weKirasi V6

• Matsime asina kudzika (kudzika kwetsime kazhinji＜mamita chiuru);
• Kumanikidzwa kwekushanda ≤20 MPa (inenge 200 kg);
• Tembiricha yekushanda ≤80°C;
• Pakati nepakati: mvura yakachena, mafuta asina kucheneswa echinyakare;
• Hapana zvinhu zvinorema (semuenzaniso, hapana kushanda kwemugodhi kana mashandiro ekukurudzira, netambo isina kumira zvachose);
• Zvinowanzoitika: matsime emvura isina kudzika ari pamhenderekedzo yegungwa, kuvharwa kwechinguvana kwematsime akasiyiwa.

Zvinodiwa paKuedza kweKirasi V6

Hapana zvinodiwa zvekuyedza zvinosungirwa; kuyedza kunogona kuitwa zvichienderana nezvinodiwa nevagadziri. Kazhinji, kuyedza kumanikidzwa kwekushanda kunoongororwa pasi pemamiriro ekupisa kwemukamuri, zvichida kuvharwa kwesimbi kwemaminitsi gumi pasina kubuda. Hapana chinodiwa chekuyedza kutenderera kwekupisa, kuyedza dynamic load, kana certification yegesi sealing.

Kirasi V5: Shanduro Yekutanga "Varwi VePatrol" — Garandi Yekuvharirwa Kwemvura

Zvinoreva zveUnyanzvi

Zvichibva paKirasi V6, Kirasi V5 inowedzera bvunzo yekubatanidza mvura. Ndiyo "chiyero chekushanda kwepasi" chinotarisirwa neAPI 11D1, nepfungwa yayo huru ichitarisa kuvimbika kwekuisa mvura pasi pemvura.

Mamiriro Ezvinhu Anoshanda Ekushandisa Mutsime weKirasi V5

• Matsime asina kudzika kusvika pakati nepakati (kudzika kwetsime: mamita 1,000-2,000);
• Kumanikidzwa kwekushanda ≤34.5 MPa (inenge 350 kg);
• Tembiricha yekushanda ≤93°C;
• Pakati nepakati: zvinwiwa zvakaita semafuta asina kuchekwa nemvura ine munyu;
• Mamiriro ekushanda akagadzikana, ane kushanduka-shanduka kwedzvinyiriro＜10% yekumanikidzwa kwakayerwa;
• Mamiriro ezvinhu akajairika: danho rekugadzira mafuta mumatsime emafuta emugungwa, matsime ekugadzira mafuta asiri egasi.
• Zvinodiwa paKuedza kweKirasi V5 (Zviratidzo Zvikuru zveAPI 11D1)
• Kuedza kumanikidzwa kwemvura: Chengeta kumanikidzwa kwemvura kwemaminitsi gumi nemashanu pasina kubuda kwemvura;
• Kuedza kuvimbika kwekuisa: Shandisa ±10% yesimba rekuisa rakatarwa pakuedza kuti uve nechokwadi chekuti zvisimbiso zvinokura zvinobudirira;

Hapana kuyedzwa kwekutenderera kwekupisa kana kuyedzwa kwemutoro we axial;

Hapana chinodiwa chekusimbisa kuvharwa kwegesi (chinhu chemvura chete ndicho chinotariswa).

Kirasi V4: "Varindi" Vepamusoro-soro Vanokwanisa Kutsungirira Mitoro YeAxial

Zvinoreva zveUnyanzvi

Zvichibva paKirasi V5, Kirasi V4 inowedzera kuyedzwa kwemutoro we axial. Inogona kuchinjika kumasimba e axial anokonzerwa nekuwedzera/kukwenya tambo uye kuzviremera, nekuvandudzwa kwayo kukuru kuri mukuwedzera "kuramba kwekuchinja kwezvisimbiso."

Mamiriro Ezvinhu Anoshanda Ekushandisa Kirasi V4

• Kudzika kwetsime: 2,000-3,000 metres;
• Kumanikidzwa kwekushanda ≤69 MPa (inenge 700 kg);
• Tembiricha yekushanda ≤121°C;
• Pakati nepakati: musanganiswa wemafuta-gasi-mvura, neCO₂ chikamu chekumanikidzwa ≤1 MPa;
• Mitoro midiki ye axial iripo (semuenzaniso, kuwedzera/kukwenya kwetambo yekupisa, kudedera kudiki);
• Mamiriro ezvinhu akajairika: danho rekugadzirwa kwematsime epombi echinyakare uye matsime egasi asina kupwanyika.

Zvinodiwa paKuedza kweKirasi V4

• Kupasa bvunzo dzese dzeKirasi V5;
• Kuedza kweAxial load: Shandisa simba re ±50 kN axial (kutevedzera kuwedzera/kukwenya tambo) uye chengetedza kumanikidzwa kwemaminitsi gumi nemashanu pasina kubuda kwemvura;
• Kuedza kutenderera kwemvura: Ita madenderedzwa gumi ekukwira nekudonha kwesimba padanho repamusoro, uchivimbisa kuvharwa zvakanaka;
• Kuyedzwa kwekuvharwa kwegasi uye kuyedzwa kwekutenderera kwekupisa hazvisati zvichidikanwa.

Kirasi V3: "Varindi" Vakavandudzwa Vakakodzera Mamiriro Ekuchinja-chinja Kwekupisa

Zvinoreva zveUnyanzvi

Zvichibva paKirasi V4, Kirasi V3 inowedzera kuyedzwa kwekuchinja kwekupisa. Inogona kuenderana nekudzika/kuwedzera kwezvisimbiso zvinokonzerwa nekuchinja kwekupisa kwemugomba, zvichiita kuti ive kirasi yakakosha ye "kuchinja kubva kumatsime echinyakare kuenda kumatsime akaomarara."

Mamiriro Ezvinhu Anoshanda Ekushandisa Mutsime weKirasi V3

• Matsime ari pakati nepakati kusvika akadzika (3,000-4,000 metres);
• Kumanikidzwa kwekushanda ≤103 MPa (inenge 1,050 kg);
• Tembiricha yekushanda ≤150°C (nzvimbo yekuchinja-chinja kwetembiricha ≤50°C);
• Pakati pepakati pane gasi shoma (gasi-oiri chiyero ≤500), ine CO₂ chikamu chekumanikidzwa ≤2 MPa;
• Kuchinja-chinja kwetembiricha/kumanikidzwa kuripo kaviri (semuenzaniso, matsime anoyerera nguva nenguva);
• Mamiriro ezvinhu akajairika: danho rekugadzirwa kwematsime egasi asina kudzika uye matsime emafuta akajairwa.

Zvinodiwa paKuedza kweKirasi V3

• Kupasa bvunzo dzese dzeKirasi V4;
• Kuedza kutenderera kwekupisa: Ita madenderedzwa matatu ari pakati pe -29°C netembiricha yakatarwa, uchichengetedza kumanikidzwa kwemaminitsi makumi matatu mushure mega yega yekudziya/kutonhodza pasina kubuda kwemvura;
• Kuedza kutenderera kwesimba: Ita madenderedzwa zana kubva pa0 kusvika ku80% yesimba rakayerwa, uchivimbisa kushanda kwakasimba kwekuvhara;

Kuedza kuchiri kushandisa nzira yemvura, pasina chinodiwa chekuvhara gasi.
