Kabati la mafuta Aina tofauti za Casing


Kabati la mafuta Kasoro ya kina kisichozidi chini ya kipenyo cha chini cha uzi au zaidi ya asilimia 12.5 ya unene wa ukuta uliobainishwa (yoyote ni mkubwa zaidi) inaruhusiwa kati ya urefu wa L C na hatua ya kutoweka kwa uzi, lakini hakuna bidhaa za kutu zinaruhusiwa kwenye uso wa Thread. Kumaliza kusaga kunaruhusiwa kuondokana na kasoro, lakini kufungua haruhusiwi kuondokana na mashimo. Chamfer ya nje ya mwisho wa bomba (65°) imehakikishwa kuwa kamili kwenye mzunguko wa 360° wa mwisho wa bomba, na kipenyo cha chamfer kinapaswa kufanya mzizi wa thread kutoweka kwenye uso wa chamfer badala ya mwisho wa bomba. uso, na hakuna makali kama makali. Chamfer ya nje ya mwisho wa bomba ni 65°~70°; Chamfer ya ndani ya mwisho wa bomba inapaswa kuwa 360° kamili chamfer pande zote, na chamfer ya ndani inapaswa kuwa 40°~50°. Iwapo kuna sehemu yoyote ambayo haijamiminwa, toa mwenyewe chamfer.

Casing ya mafuta ni aina ya bomba kubwa la kipenyo, ambalo lina jukumu la kurekebisha ukuta au shimo la mafuta na gesi ya mafuta. Casing huingizwa kwenye shimo la kisima na kulindwa kwa saruji ili kuzuia uundaji wa miamba inayotenganisha shimo na shimo kutoka kwa kuanguka, na kuhakikisha mzunguko wa matope ya kuchimba visima ili kuwezesha kuchimba visima na uzalishaji. Kiwango cha chuma cha kabati la mafuta:



H40, J55, K55, N80, l80, C90, T95, P110, Q125, V150
, nk. Fomu za usindikaji wa mwisho wa casing: thread fupi ya pande zote, thread ya pande zote ndefu, thread ya sehemu ya trapezoid, buckle maalum, nk. Inatumiwa hasa kusaidia ukuta wa kisima wakati wa mchakato wa kuchimba visima na baada ya kukamilika kwa kisima, ili hakikisha uendeshaji wa kawaida wa mchakato wa kuchimba visima na kisima kizima baada ya kukamilika. Sekta ya mafuta ni idadi kubwa ya matumizi ya tasnia ya bomba la mafuta, bomba la mafuta katika tasnia ya petroli linachukua nafasi muhimu sana: kiasi cha bomba la mafuta ni kubwa, gharama ni nyingi, uwezo wa kuokoa gharama na kupunguza gharama ni kubwa. kubwa. Matumizi ya bomba la kisima cha mafuta yanaweza kuhesabiwa kwa idadi ya miguu iliyopigwa kwa mwaka. Kulingana na hali maalum ya nchi yetu, kwa ujumla kila kuchimba visima 1m kunahitaji 62kg ya bomba la kisima cha mafuta, ambapo 48kg casing, neli 10kg. Groove kipofu ya ukubwa sawa na mpasuko huwekwa kwenye ukuta wa ndani wa bomba. Kuchimba bomba 3kg, kuchimba kola 0.5kg; 2. Tabia ya mitambo na mazingira ya mabomba ya petroli ina athari muhimu katika kupitishwa kwa teknolojia ya juu na ongezeko la ufanisi wa uzalishaji katika sekta ya petroli; 3 Upotevu wa bomba la mafuta ni kubwa, kutegemewa na maisha ya mafuta ni muhimu sana kwa tasnia ya mafuta. [(kipenyo cha nje – unene wa ukuta)* Unene wa ukuta]*0.02466=kg/ mita (uzito kwa kila mita).

Hali tofauti za kisima, kina kisima, matumizi ya darasa la chuma pia ni tofauti. Katika mazingira ya babuzi, casing yenyewe pia inahitajika kuwa na upinzani wa kutu.  API imefumwa chuma bomba katika hali ya kijiolojia ya maeneo tata pia zinahitaji casing kuwa na upinzani kuponda. Mirija ya kufyonza hubeba mafuta na gesi kutoka chini ya kisima hadi juu ya uso. Fomu ya uunganisho wa nyuzi: casing fupi ya thread ya pande zote (STC); Ufungaji wa uzi wa pande zote wa muda mrefu (Ltc) Ufungaji wa uzi wa sehemu ya trapezoidal (BTC); Casing iliyounganishwa moja kwa moja (XC) neli isiyofikiriwa (NU); Mirija minene ya nje (EU); Mirija ya kiunganishi cha kuunganisha (IJ).



api 5ct mfuko wa mafuta

,Kiwango cha bomba la mafuta la API 5L, kabati ya mafuta ya API 5CT, kiwango cha bomba la mafuta ya API 5L, kabati ya mafuta imetengenezwa kwa bomba la chuma isiyo na mshono, bomba la chuma lililosocheshwa la umeme na bomba la chuma lililoviringishwa kama malighafi, kwa kugeuza waya wa CNC. Uunganishaji unachukua mchakato wa kimataifa wa hali ya juu wa phosphating wa mfululizo safi wa manganese. Filamu ya phosphating ina nguvu kubwa ya kumfunga, fuwele sare na mnene, ugumu wa juu, upinzani wa kutu na upinzani wa kujitoa. Bidhaa hizo zimekaguliwa na Taasisi ya Utafiti wa Bomba la Petroli la Xi ‘, na viashiria vya utendaji vinaendana na mahitaji ya kiufundi ya kawaida. Bomba la chuma la ASTM linaweza kugawanywa katika daraja tofauti za chuma kulingana na nguvu ya chuma yenyewe, yaani J55, K55, N80, L80, C90, T95, P110, Q125, V150na kadhalika.

Mchakato mzima wa kuchimba visima hautumii tena bomba la kuchimba visima, kola ya kuchimba visima, nk. Sehemu ya kuchimba visima ni matumizi ya uvuvi wa kamba ya waya, kwenye casing ili kufikia kuinua kidogo kwa kuchimba visima, ambayo ni, kufikia uingizwaji wa zana za kuchimba visima, kupunguza. safari na blowout, kukwama na ajali nyingine, kuboresha kuegemea kuchimba visima, kupunguza gharama

Different well conditions, well depth, the use of Steel grades are also different. In the corrosive environment, the casing itself is also required to have Corrosion resistance. API Seamless Steel Pipe in the geological conditions of complex places also require the casing to have a crush resistance. Suction Tubing mainly carries Oil and Gas from the bottom of the well to the surface. Threaded Connection form: short round thread casing (STC); Long round thread casing (LTC) Partial trapezoidal thread casing (BTC); Straight-connected casing (XC) unthickened tubing (NU); External thickened tubing (EU); Integral connector tubing (IJ).
