(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

將氟丁基防水嵌縫膠膠筒以25%的壓縮率放人300℃蒸汽環(huán)境中22 h,然后測(cè)定每輪次的壓縮永久變形率,實(shí)驗(yàn)結(jié)果如圖1所示。高溫蒸汽模擬試驗(yàn)輪次氟丁基防水嵌縫膠膠筒多輪次高溫蒸汽模擬實(shí)驗(yàn)結(jié)果可知,300℃實(shí)驗(yàn)溫度下丁基防水嵌縫膠膠筒經(jīng)過(guò)4輪次高溫蒸汽后,壓縮永久變形均小于55%,符合HGlT2701-1995油氣田用壓縮(YS)式封隔器丁基防水嵌縫膠膠筒要求壓縮永久變形不大于55%的要求。在300℃的高溫蒸汽下,對(duì)丁基防水嵌縫膠膠筒進(jìn)行了4輪次老化實(shí)驗(yàn),每輪次老化時(shí)間70 h,每輪次老化后測(cè)定丁基防水嵌縫膠膠筒的拉伸強(qiáng)度和拉斷伸長(zhǎng)率。
可知,經(jīng)過(guò)一輪次300℃高溫蒸汽老化后,丁基防水嵌縫膠膠筒的拉伸強(qiáng)度和拉斷伸長(zhǎng)率都不同幅度的減小,但之后經(jīng)過(guò)2,3,4輪蒸汽老化后,拉伸強(qiáng)度和拉斷伸長(zhǎng)率變化幅度較小,均滿足HG/T 2701-1995油氣田用壓縮(YS)式封隔器丁基防水嵌縫膠膠筒標(biāo)準(zhǔn)的要求,可以應(yīng)用于多輪次注汽防砂。
為驗(yàn)證新型高溫高壓丁基防水嵌縫膠膠筒的可靠性,該丁基防水嵌縫膠膠筒研究成功后,配合充填工具在孤島油田普通稠油油藏、單家寺油田超稠油油藏、王莊油田敏感性稠油油藏中應(yīng)用4口井。液23.9 t,平均日產(chǎn)油11.2 t,累油10 729 t,與同單元其他油井相比,平均日增油6.1 t。取得了良好的增油效果。同時(shí),SJ2-47X9井實(shí)現(xiàn)了三輪次注汽生產(chǎn),為實(shí)現(xiàn)稠油油藏蒸汽吞吐井多輪次注汽生產(chǎn)、達(dá)到長(zhǎng)效生產(chǎn)、提高油井產(chǎn)量提供了可靠的技術(shù)手段。
(1)在深人研究氟橡膠機(jī)理的基礎(chǔ)上,進(jìn)行了高溫高壓丁基防水嵌縫膠膠筒配方改性研究,采用了雙酚類硫化體系、雙補(bǔ)強(qiáng)體系,橡膠密封制品檢驗(yàn)結(jié)果表明,各項(xiàng)指標(biāo)均符合設(shè)計(jì)要求,能滿足多輪次注汽稠油開(kāi)采需要,解決了稠油熱采井多輪次蒸汽吞吐對(duì)封隔器密封件耐高溫、高壓及耐磨蝕的應(yīng)用難題。
(2)新型高溫高壓丁基防水嵌縫膠膠筒配以相應(yīng)的防砂工具及防砂工藝可實(shí)現(xiàn)稠油熱采防砂井多輪次蒸汽吞吐開(kāi)采要求,能夠滿足高溫、高壓及多輪次注汽油井防砂、封隔等復(fù)雜工況,具有良好的現(xiàn)場(chǎng)推廣應(yīng)用價(jià)值。http://hbxqtax.com/
