【正文】 對特低滲透油層來進行儲層的改造。2 112 RRpc ? 式中: c2p— 第二種毛細管力; R39。 ( 3)巖石表面油膜量大 原油化合物組成的復雜混合物有烴類和非烴類,包含大量的極性物質。早期注水分為油田經過試采,鑒定了油藏主要驅動機理后,就開始注水。特低滲透油層傳導能力較差,生產能力特低,行列注水方式注水井與中間排生產井距離較大,一般并不適應,很多常規(guī)特低滲透 油田一般都采用面積注水的方式。 由此,便可根據以上公式在計算機上采用曲線交匯法算得經濟合理井網密度。非連續(xù)剩余油可在其上形成連續(xù)的油相,委員有流動 提供通道Gpmin,既降低了水的流度,從而改善了流度比,增加了波及系數,提改了采收率,此時 Gpmin 所對應的井距即是油層能夠動用的極限注采井距。 合理的井網密度應以經濟效益為中心,同時要合理利用地下資源,達到較好的開發(fā)效果。 特低滲透油藏有效動用方式研究現狀 直接在油田上進行試驗獲取資料,伊邊境性分析,鉆井觀 察,這種方法可用在勘探初期或油田開發(fā)過程個辦法中,盡可量的延長無水開采期與低含水開采期,一般都先用彈性能量和溶解氣驅能量開采,井下測試,分層測試壓力和油氣水產量,從而分析由曾分析,采用注水保持能量后,開辟生產試驗去,油田開發(fā)初期或為達到某種實驗的目的,如提高采收率的措施,要在油田內部選擇一個代表性的地區(qū),例如大慶油田的小井距進行單層注水和各種提高采收率的方法的實驗方法的有點是,看得見摸得著,因為他客觀存在,避免了人為的誤差,成本高周期長,不能重復進行,其次為邊水驅和彈性驅??晌覈淖鉁y驗起步比較晚,經驗也少,措施不當易于造成氣竄現象這樣很影響開發(fā)的結論。 關鍵詞: 低滲透;合理井距;注水 ;注氣;數值模擬 哈爾濱石油學院本科生畢業(yè)設計(論文) 2 Abstract The ultralow permeability accounts for 10% of the geological reserves of developed oil fild,and occupy half of the proven but untapped reserve on urgent needs to carry on effective exploitation to the ultralow permeability reservoir,satisfies the oil demand of the same time, the rising oil price in recent years creates the economic feasibility for ultralow permeability reservoir development. This paper researches ultralow permeability reservoir development technologies both at home and the well spacing and the well pattern density relations, as well as technical well spacing and economical well spacing putational method,thus the analysis method of rational well spacing through the technical well spacing and the economical well spacing putation has through numerical simulation researching for row well pattern,fivespot pattern,reverse ninespot pattern,skewed fourspot injection pattern and reverse sevenspot patten,determining the wellpattern type that suits the ultralow permeability by the watercut and recovery on the research of rational well spacing and wellpattern, elaborating the waterflooding recovery feature,existing problems and influence factors,studing on advanced and cyclic water injection by using numerical simulation method and analysing it’s influencing ,by using numerical simulation method,studying the carbon dioxide flooding and nitrogen flooding,the consideration influencing factor includes gas injection occasion,injection rate,injection mode,gaswater ratio,slug size and so ,through the prehensive parison to the water fooding and gas flooding, summarizing and analyzing the effective development fashion that suits the ultralow permeability reservoir. Keywords: Ultralow permeability; Rational well spacing ; Waterflooding, Gasflooding; Numerical simulation 哈爾濱石油學院本科生畢業(yè)設計(論文) 3 目 錄 摘 要 .............................................................................................................................. 1 第 1 章 緒論 .................................................................................................................. 5 研究目的和意義 ............................................................................................. 5 國內外研究現狀 ............................................................................................. 5 特低滲透油藏合理井距研究現狀 ...................................................... 5 特低滲透油藏有效動用方式研究現狀 .............................................. 7 第 2 章 特低滲透油藏井距研究 .................................................................................. 8 井距與井網密度的關系 ................................................................................. 8 技術井距 ......................................................................................................... 9 技術井距的分類 .................................................................................. 9 特低滲透油藏井距研究 ...................................................................... 9 技術井距的確定 .................................................................................. 9 經濟井距 ....................................................................................................... 12 合理井距的確定 ........................................................................................... 15 第 3 章 特 低滲透油藏注采井網研究 ........................................................................ 17 面積注水井網合理布置的方法和依據 ....................................................... 17 第 4 章 特低滲透油藏注水開發(fā)方式研究 ................................................................ 20 特低滲透油藏注水開采特征 ....................................................................... 20 特低滲透油藏滲流環(huán)境特征 ............................................................ 20 特低滲透油藏注水開采特征 ............................................................ 23 注水開發(fā)存在問題及其影響因素 ............................................................... 25 注水開發(fā)存在的問題 ........................................................................ 25 注水開發(fā)的影響因素 ........................................................................ 26 超前注水開發(fā) ............................................................................................... 27 超前注水開發(fā)原理 ............................................................................ 27 超前注水數值模擬研究 .................................................................... 27 周期注水開發(fā) ............................................................................................... 31 周期注水開發(fā)原理 ............................................................................ 31 周期注水數值模擬研究 .................................................................... 32 第 5 章 特低滲透油藏開 發(fā)方式選擇 ........................................................................ 34 注水開發(fā)方式分析 ....................................................................................... 34 注氣開發(fā)方式分析 ....................................................................................
