摘 要:K344型封隔器是油氣井作業(yè)中使用的一種井下工具。屬于水力擴(kuò)張式封隔器,懸掛式固定,液壓坐封,液壓解封,依靠膠筒的膨脹來密封套管。本次畢業(yè)設(shè)計(jì)設(shè)計(jì)的K344-114型封隔器是一種采用了活動(dòng)式保護(hù)塊的擴(kuò)張式封隔器,主要用于注水、試油、采油、找水、卡堵水、酸化等工藝,K344-114型封隔器易于坐封、解封,不需要機(jī)械力的幫助,對(duì)井眼適應(yīng)性強(qiáng),并且可以重復(fù)使用,所以針對(duì)不同油田的不同情況,可以使用該類型的封隔器進(jìn)行地層測(cè)試。 本文概述了油田常用的封隔器的類型、參數(shù)、命名及其工作原理;討論了目前封隔器所用的膠筒的發(fā)展現(xiàn)狀,密封元件“防突”措施的類型,分析了封隔器的工作原理以及結(jié)構(gòu)特征并對(duì)各重要零部件進(jìn)行強(qiáng)度校核,密封元件坐封力的計(jì)算、彈簧數(shù)據(jù)的計(jì)算、封隔器基本效應(yīng)的分析等。 關(guān)鍵詞:封隔器 密封 防突 坐封力 管柱受力
ABSTRACT:Type K344 packer is a down hole tool used in the oil and gas Wells homework。Belongs to the hydraulic expansion packer, hanging fixed, hydraulic setting,hydraulic un-ban,depend on the expansion of the rubber tube to seal casing。The graduation project designed K344-114 packer is protected with a movable block expansion packer, mainly used for water、oil testing、 oil、looking for water、 plugging the card,acidification and other processes,K344-114 -type packer easy setting,reopened,without the help of mechanical force on the wellbore adaptable,and can be reused,so the different situations for different fields,you can use this type of packer for formation test。 This paper summarizes the field commonly used type of packer,parameters,naming and its working principle, discussed the current packer plastic tube used in the current development,the sealing element " outburst " the types of measures ,analyzes packer working principle and structure of all major components and strength check, packer sealing element force calculation, the calculation of the spring data,packer basic effect analysis。 Key word:Packer;Seal up;The outburst;Seat sealing force;String stress |
