【摘要】：針對深井與復雜井尾管下入難度大、尾管重疊段封固能力低等問題,研制了具有坐掛、旋轉(zhuǎn)、封隔等功能的新型尾管懸掛器。在旋轉(zhuǎn)封隔尾管懸掛器整體結(jié)構(gòu)設計的基礎上,開展了軸承、扭矩傳遞、高壓封隔等關鍵技術(shù)研究。利用ABAQUS軟件分析了重載軸承、扭矩套及封隔器鎖緊機構(gòu)的應力和應變情況,據(jù)此優(yōu)化了結(jié)構(gòu)和設計參數(shù),并通過試驗驗證了各部件的性能。地面試驗表明,軸承在800 k N的載荷作用下,旋轉(zhuǎn)壽命達到55 h,扭矩傳遞裝置抗扭達到41 k N·m,高壓封隔器耐溫達150℃、耐壓達70 MPa。在星火101井的現(xiàn)場試驗中,取得了坐掛、丟手、旋轉(zhuǎn)尾管及封隔器坐封等作業(yè)的一次性成功。該井固井質(zhì)量優(yōu)質(zhì)率達到了75.6%,尾管固井質(zhì)量相對鄰井有明顯提高,高性能懸掛器結(jié)構(gòu)設計的合理性和可靠性得到驗證。
[Abstract]:A new type of tailpipe suspension with the functions of sitting, rotating and sealing is developed to solve the problems such as the difficulty of entering the tailpipe in deep and complex wells and the low sealing ability of the overlay section of the tailpipe.On the basis of the integral structure design of the rotary sealing tube suspension, the key technologies such as bearing, torque transfer and high pressure sealing are studied.The stress and strain of heavy load bearing, torque sleeve and Packer locking mechanism are analyzed by using ABAQUS software. The structure and design parameters are optimized accordingly, and the performance of each component is verified by test.The ground test shows that under the load of 800kN, the rotating life of the bearing is up to 55 h, the torsion resistance of the torque transfer device is 41 km, the temperature resistance of the high pressure Packer is 150 鈩，
