1、可伸縮熱采封隔器的設(shè)計(jì)摘要：由于目前熱采封隔器多采用熱脹式，該類型封隔器沒(méi)有管柱受熱膨脹補(bǔ)償裝置，而且解封時(shí)要降溫，但注完蒸汽后井溫很難降低，造成解封困難，密封效果不好。針對(duì)這些問(wèn)題，設(shè)計(jì)了可伸縮熱采封隔器。該封隔器主要由密封機(jī)構(gòu)，坐封機(jī)構(gòu)，解封機(jī)構(gòu)，扶正錨定機(jī)構(gòu)，熱力伸縮補(bǔ)償機(jī)構(gòu)，安全脫卡機(jī)構(gòu)組成。它將封隔器與伸縮管設(shè)計(jì)成一體，確保了管柱受熱膨脹并簡(jiǎn)化了熱采管柱的結(jié)構(gòu)；采用V形膨脹石墨密封圈組成密封系統(tǒng)，確保伸縮管熱力伸長(zhǎng)時(shí)封隔器的密封性；采用左旋上提管柱坐封，右旋脫鎖，上提管柱解封，操作過(guò)程中不需降溫，確保了坐封與解封的可靠性。與常規(guī)熱采封隔器相
2、比，該封隔器上提坐封時(shí)操作簡(jiǎn)單、安全，坐封顯示準(zhǔn)確；注汽施工過(guò)程中，封隔器懸掛在套管內(nèi)，承受單向壓差；采用碟形彈簧壓力補(bǔ)償復(fù)合式密封件，密封性能好；上提管柱解封時(shí)操作方便，封隔器解封順利。關(guān)鍵詞：熱采封隔器；伸縮管；密封；熱力補(bǔ)償；結(jié)構(gòu)設(shè)計(jì)42ScalablePackerOfThermalRecoveryAbstract：Mostofthermalrecoverypackersbeingusedcurrentlyarethermalexpansionpackers.Withpoorsealingperformance,thosepackershave
