Kodi mapulagi otsekeka a mlatho angalowe m'malo mwa mapulagi obowoka wamba?

Pakali pano, yopingasa bwino fracturing luso wakhala chida chofunika posungira kukonzanso ndi bwino kuonjezera kupanga chitsime chimodzi. Monga chimodzi mwazinthu zofunika kwambiri zopangira fracturing, mapulagi a mlatho amagwiritsidwa ntchito kwambiri. Pakalipano, mapulagi a mlatho wamba amaphatikizapo mapulagi obowoleredwa ndi mapulagi akuluakulu a mlatho. Mapulagi obowola mlatho amatha kuyambitsa ngozi zapabowo komanso kuwononga ndalama zambiri pakumangira zida zobowola pambuyo pakuphwanyidwa, pomwe zinyalala ndi madzi ogwirira ntchito amatha kuwononga posungira.

Thupi lalikulu la pulagi yosungunula ya mlatho imapangidwa ndi zinthu zopepuka komanso zamphamvu kwambiri zotulutsa mphamvu zambiri, kukana kwa 70 MPa, madzi osungunuka, komanso nthawi yosungunuka. Ikang'ambika, pulagi ya mlatho wosungunuka imakumana ndi madzi a m'chitsime pansi pa kutentha kwambiri komanso kuthamanga kwambiri, imasungunuka ndikutuluka pachitsime ndi madzi otayira. Kupangidwa kwa chida ichi ndikusintha kwathunthu kwa chida chachikhalidwe cha plug fracturing.

Mtengo wa mapulagi osungunuka mlatho ndi wofanana ndi wa mapulagi ophatikizika ochokera kunja, koma njira yotsatirira yamapulagi achikhalidwe ndi yayitali komanso yokwera mtengo, pomwe kugwiritsa ntchito mapulagi osungunuka kumatha kuchepetsa kwambiri ndalama zomanga pambuyo pomanga fracturing. ntchito. Mapulagi osungunuka a mlatho amatha kuchepetsa mwayi wokhala pakati pa ntchito yowonongeka, ndipo ngakhale pulagi ya mlatho itatsekedwa, imatha kusungunuka kudzera muukadaulo wamankhwala ofulumira, motero kuchepetsa chiopsezo chokonzanso pulagi ya mlatho.

Pulogalamu ya Diossovable Bridge

mapulagi a dissovablebridge akupezeka m'makalasi a kutentha awa: <50°C, 50-80°C, 80-120°C, ndi 120-160°C. Pali magawo 4 a kutentha kwathunthu. Malinga ndi kuya kwakukhala, kutentha kwa stratum kwa kuya kumatha kuwerengedwa, ndipo pulagi yofananira ya dissovablebridge imatha kusankhidwa.

Pulagi ya dissovablebridge imapangidwa ndi dissovable magnesium alloy. Itha kukwaniritsa zofunikira zamphamvu pansi pa kutentha kwambiri komanso kuthamanga kwambiri, ndipo mankhwalawa ndi pafupifupi osawola mu Qingshuihe guagel solution. Ndi kusintha chilinganizo, akhoza lizilamuliridwa kupasuka pansi pa kutentha osiyana ndi milingo mineralization, ndi Kusungunuka liwiro n'zogwirizana ndi mlingo mineralization ndi kutentha downhole, ndi mankhwala kusungunuka ndi mu mawonekedwe a inaimitsidwa ufa, amene n'zosavuta kubwezedwa. ku ngalande.

Zinthu zowonongeka zisanachitike

Ufa pambuyo kutha

The mankhwala kudzera mayeso bwino mayeso, 75Mpa zinthu maola 24 pansi pa mavuto popanda kugwetsa kuthamanga, kusindikiza ntchito ndi zabwino kwambiri, kudya kuvunda, kusungunuka mu sanali zomata phala flowable madzi, mokwanira kukwaniritsa zofunika za dissolvable pulagi, akhoza m'malo ofanana kunja kunja. mankhwala.
