      常規試井分析是指上世紀80年代初,國外學者提出的基于不穩定滲流的解析系列試井方法,主要使用壓力及導數試井分析方法。軟件可完成采油井、注水井及采氣井壓降及壓力恢復試井分析,采用多流量疊加計算典型曲線圖版用于壓力及導數曲線擬合 ……>> 詳情
      試井分析中的半對數解釋方法是基于不穩定滲流的徑向流理論,而壓力及導數雙對數擬合試井分析是基于計算典型曲線圖版,這兩種方法都需要生產及關井時間達到徑向流,對于低滲透油氣藏在有效的測試時間內,很難滿足這個要求。軟件采用早期小信號提取及放大的試井分析方法,節約了關井測試時間,可以提高資料解釋率和壓力資料解釋精度,從而降低成本、增加產量。早期試井分析已在現場得到應用驗證 ……>> 詳情
      DST段塞流動是指在油井開采(或生產)期間,液體不斷地從地層流向井筒,而井筒中的流體還未到達地面。DST段塞流動在我國低滲透油藏中大量存在,而國外沒有提出相應的試井解釋方法。采用已知流量的解釋分析方法進行試井分析不能得到準確的解釋結果,所以軟件首先建立了地層及井筒耦合流動的方程(見圖1),確定了流量與井底壓力的關系,進而提出了流動與恢復的聯合試井分析方法,解決了DST段塞流的壓力資料解釋問題,相關技術已在我國探井測試中得到廣泛應用 ……>> 詳情
      在低滲透(滲透率>10md)及特低滲透(滲透率>1md)油氣藏中,油藏供油能力非常差,已不能連續開采。對這樣油層的開發一般采用間歇方式采油,間歇采油使試井解釋問題十分復雜:生產階段或停產階段,地層都不斷地生產;在生產期間,井筒中的液面也在上升,地層的壓降漏斗也在發生變化;產量和井底壓力都是未知的。辰工科技根據間抽及提撈采油的特點,建立了間歇采油的數學模型,提出了全壓力歷史擬合的試井分析方法 ……>> 詳情
      縫洞型油藏非均質性非常嚴重,儲層基質物性差,基本不含油,產油部位主要在溶洞、裂縫發育段,鉆井過程中如果鉆遇溶洞、裂縫發育帶,則油井產能高。這類油藏試井曲線不僅種類多,而且部分曲線形態復雜。軟件以縫洞型油藏壓力恢復試井曲線特征為研究對象,結合勘探開發期間的地震、地質、測井、錄井等數據,以力學三大守恒定律為基礎,建立井-縫-洞-地層流體流動模型;采用Laplace變換及數值反演技術進行方程求解,得到縫洞型油藏試井分析典型曲線;采用典型曲線擬合及全歷史計算方法,實現縫洞型油藏試井分析 ……>> 詳情
      產能評價是油氣田勘探開發的重要工具之一,軟件根據油氣田勘探開發的特點研制,能對自噴井和非自噴井進行壓降、壓恢和探邊試井設計,特別是非自噴井試井設計功能在國內首次實現。軟件考慮了油、氣、水等流體,地層滲流及各種類型井筒,同時提供各種不同類型的邊界:外邊界可選擇封閉和定壓的隨機組合。對于部分射開、水平裂縫、部分壓開及水平井等提供了考慮氣頂及底水 ……>> 詳情
