邊際井
英文
marginal well-
According to actual situation of production wells, external boundary conditions and coupled inner boundary conditions between welibore and adjacent rocks, welibore and production zones, adjacent rocks and production zones are constructed, and an alternate direction implicit finite difference algorithm ( adi ) is used to solve temperature models
根據生產井的實際情況，構建起外邊界條件以及井筒與圍巖、井筒與產層、圍巖與產層之間的耦合內邊界條件，採用交替方向半隱式有限差分方法（ adi方法）求解所建立的井下溫度場模型。Then the shear and torsion strength of the beams and the number of stirrups were checked. the program for this system is pragmatic because it includes some cases that are always met in practice
本文所編制的預應力混凝土井字梁計算機輔助設計系統考慮了實際工程中常遇到的邊梁扭矩較大、預應力筋相碰等問題，因此具有實用性。The analysis illustrates that : the total return of water resources for zhangye oasis agriculture is increasing by degrees as times goes by, and it would be fluctuated accordingly by the natural disaster ; the average returns are comparetively high at the period of late 1990s and early 1980s ; the marginal returns are decreasing by degrees as the water consumption increase ; and the water resources marginal returns in linze and zhangye are nearly of zero. as for the space distribution, the average returns and marginal returns of agriculture consumption in the mountain spring area are higher than those in the well area, which shows that the mountain area has bigger production potential
就空間分佈而言，對張掖地區各子綠洲和甘州區內不同灌區的代表鄉鎮的分析具有相同的結論:山水灌區農業用水的邊際效益高於盆地中心的井水、泉水灌區;山區農業生產受水資源的制約更加明顯，同時也具有比平川綠洲更大的生產潛力;山丹、民樂等山水灌區的綠洲需要增加灌溉水量以促進農業生產的發展，而綠洲核心的井泉灌區在現有技術條件下，不需要再擴大用水規模。According to the new criterion for classification of oil and gas resources / reserves ( gb / t19492 - 2004 ) issued in 2004, this paper reviews the studied methods at home and abroad for the purpose of establishment of new series of recoverable reserves such as technically recoverable reserves, economic recoverable reserves, sub - economic recoverable reserves and remaining economic recoverable reserves of oil - gas fields
摘要按照2004年頒布的新的《石油天然氣資源儲量分類》 （ gb - t19492 - 2004 ）標準，為了建立和形成油氣田技術可采儲量、經濟可采儲量、次經濟可采儲量和剩餘經濟可采儲量等新的可采儲量系列，在總結國內外研究方法的基礎上，結合油田的地質開發特點，根據我國現行的財稅制度，以現金流法為主要方法，進一步研究提出了經濟極限法、井網密度法、邊際成本法、類比法等經濟可采儲量計算方法。Highly - displacement drilling is an effective technology to exploit peripheral oilfield
