ry technology development provides new ideas, which improve the recovery of speeding up the pace of technical research has an extremely important role. Because the reservoir permeability is extremely low, conventional mining style has cannot achieve the desired effect of strata, and caused irreversible damage, for the following assignments, therefore left hidden trouble by physical method, physical method to increase production of oil production including acoustic and ultrasonic extraction technology, highenergy gas fracturing technology, low frequency impulses recovery technique, vibration and artificial earthquake recovery technique, hydraulics oscillation and high pressure water jet solution, plugging technology electric field and magic field, such as microwave field recovery technique. This paper focuses on the acoustic vibration of the system yield mechanism study, summarizes various acoustic vibration characteristics and applicability to increase production. Key words: ultralow permeability reservoirs。由于該油藏滲透率極低,常規(guī)開采方式已不能達到預(yù)期的效果,且對地層造成不可恢復(fù)的損害 ,為以后的作業(yè)留下隱患,因此采用物理法增產(chǎn)技術(shù), 物理法采油包括聲波與超聲波采油技術(shù),高能氣體壓裂技術(shù),低頻電脈沖采油技術(shù),振動及人工地震采油技術(shù),水力振蕩及高壓水射流解堵技術(shù),磁場、電場及微波場采油技術(shù)等。 分類號 : 單位代碼 : 密 級 : 一般 學(xué) 號 : (僅供參考學(xué)習(xí)切勿抄襲) 本科畢業(yè)論文(設(shè)計) 題 目 : 特低滲油藏 聲波振動增產(chǎn)的機理研究 專 業(yè) : 石油工程 姓 名 : XXXXXXXXX 指導(dǎo)教師 : XXXXXXXXX 職 稱 : 講 師 答辯日期 : 二〇一 一 年 六 月 四 日 目錄 1 引言 ................................................................... 1 研究意義 .......................................................... 1 國內(nèi)外現(xiàn)狀 .................................................... 2 2 損害油層的因素 ......................................................... 2 鉆井損害 .......................................................... 2 鉆井泥漿中固相物質(zhì)的侵入 ..................................... 2 鉆井液濾液侵入 .............................................. 3 固井損害 .......................................................... 3 前置液和隔離液損害 .......................................... 3 水泥漿損害 .................................................. 3 射孔損害 .................................................... 3 完井液和修井液的損害 .............................................. 4 礫石充填的損害 .................................................... 4 生產(chǎn)過程中的損害 .................................................. 4 增產(chǎn)措施過程中的損害 .............................................. 4 洗井 ......................................................... 4 酸處理 ...................................................... 5 堵水作業(yè) .................................................... 5 注入井
