詳細說明

Y441-115封(feng)(feng)(feng)(feng)(feng)隔器(qi)(qi)具有(you)雙向錨定功能，它廣泛應用(yong)于分(fen)層試(shi)油(you)、采油(you)、找漏、卡堵水等工藝中，特別使用(yong)于井(jing)斜大，常規封(feng)(feng)(feng)(feng)(feng)隔器(qi)(qi)不(bu)易座(zuo)封(feng)(feng)(feng)(feng)(feng)的工藝中。管柱(zhu)可(ke)采用(yong)丟(diu)(diu)手(shou)和(he)不(bu)丟(diu)(diu)手(shou)兩種(zhong)形(xing)式。該封(feng)(feng)(feng)(feng)(feng)隔器(qi)(qi)采用(yong)液(ye)壓座(zuo)封(feng)(feng)(feng)(feng)(feng)，雙向卡瓦錨定，上提油(you)管解封(feng)(feng)(feng)(feng)(feng)，承壓能力高，可(ke)多級使用(yong)。

二、結構 

Y441封(feng)隔器主(zhu)要由(you)座封(feng)液缸機(ji)構(gou)，卡瓦總(zong)成機(ji)構(gou)，鎖(suo)緊機(ji)構(gou)及(ji)解封(feng)機(ji)構(gou)等組成。

三、使用(yong)說明與工作原理 

當封(feng)(feng)隔(ge)(ge)(ge)器(qi)下到設計位置(zhi)后，向(xiang)油(you)管(guan)(guan)(guan)(guan)內(nei)加(jia)(jia)壓(ya)(ya)(ya)，加(jia)(jia)壓(ya)(ya)(ya)過(guo)程(cheng)要(yao)緩(huan)慢（分3-5Mpa，8-10 Mpa，13-15 Mpa，18-20 Mpa加(jia)(jia)壓(ya)(ya)(ya)，每次間隔(ge)(ge)(ge)3-5分鐘），使封(feng)(feng)隔(ge)(ge)(ge)器(qi)座封(feng)(feng)，封(feng)(feng)隔(ge)(ge)(ge)器(qi)坐封(feng)(feng)后，從(cong)套管(guan)(guan)(guan)(guan)內(nei)驗封(feng)(feng)，如(ru)驗封(feng)(feng)失敗，可(ke)(ke)從(cong)油(you)管(guan)(guan)(guan)(guan)加(jia)(jia)壓(ya)(ya)(ya)22-25MPA，穩壓(ya)(ya)(ya)5分鐘，重(zhong)新驗封(feng)(feng)以確認驗封(feng)(feng)是(shi)否可(ke)(ke)靠。（如(ru)采用丟手形(xing)式，不(bu)(bu)裝蘿(luo)卜頭調(diao)卡離井口0.5-1米打(da)壓(ya)(ya)(ya)，工(gong)具(ju)丟開后，上(shang)(shang)提管(guan)(guan)(guan)(guan)柱(zhu)(zhu)3-5m，再緩(huan)慢下放進行探(tan)(tan)井，直(zhi)至探(tan)(tan)著為止，探(tan)(tan)井力不(bu)(bu)大于(yu)10KN。工(gong)具(ju)無位移，說明作封(feng)(feng)可(ke)(ke)靠）。如(ru)單級使用該封(feng)(feng)隔(ge)(ge)(ge)器(qi)，解封(feng)(feng)時，先慢慢上(shang)(shang)提管(guan)(guan)(guan)(guan)柱(zhu)(zhu)，觀察指重(zhong)表的變化，當負荷超過(guo)原(yuan)管(guan)(guan)(guan)(guan)柱(zhu)(zhu)懸重(zhong)70-80KN，沒(mei)解封(feng)(feng)時將管(guan)(guan)(guan)(guan)柱(zhu)(zhu)放回(hui)至超出原(yuan)管(guan)(guan)(guan)(guan)柱(zhu)(zhu)懸重(zhong)10KN左(zuo)右，再上(shang)(shang)提管(guan)(guan)(guan)(guan)柱(zhu)(zhu)，直(zhi)到   解封(feng)(feng)為止。如(ru)多(duo)級使用，參單級解封(feng)(feng)方法。
