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余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。

Comparing with the logistic s and the hu - chen - zhang s mathematic models , this model has taken into account simultaneously the influence due to time duration of development and the subground residual recoverable reserve , so it results in more compact structure of the new model and the more evident interrelation between the variables 與邏輯斯蒂和胡-陳-張等數學模型比較,該模型的特點是同時考慮了開發時間和地下剩余可采儲量對累積產量增長率的影響,從而使模型結構更加嚴謹、變量之間的相關程度更加顯著。

Finally , this paper develops a model for estimation of the reserves value , which allows the estimations of the economic recoverable reserves and the remaining economic recoverable reserves to be more scientific by elaborating given parameters hypotheses and by converting the estimation of physical quantity into that of combination of both physical quantity and value quantity , thus brings the work in line with the international practice for reserves estimation 同時,建立了儲量價位評估模型,對評估過程中參數的假設做了詳細闡述,經濟可采儲量評估由實物量轉向了實物量與價值量相結合,使得對經濟可采儲量、剩余經濟可采儲量的評估更加科學,并與國際儲量評估方法接軌。

Based on study of previous models for production rate prediction , this paper presents a newly established differential equation of accuniulated production increase rate , and works out the practicable equation used for prediction of oilfield annual production sum , accumulated production and recoverable reserve 在研究以往產量預測模型的基礎上,提出了一種新的油氣田累積產量增長率微分方程,并由該方程得到了預測油氣田年產量、累積產量和可采儲量的具體方程。

Based on this method , this paper presents the methods for quickly forecasting the technologically recoverable re - serves , economically recoverable reserves , remaining technologically recoverable reserves and remaining economically recoverable re - serves 基于產量遞減法,提出了預測油氣田技術可采儲量、經濟可采儲量、剩余技術可采儲量和剩余經濟可采儲量的快速方法。

The calculation results demonstrate that the risk of developing maginal oilfield is high and that the uncertainty of investment , oil price and recoverable reserves is the main reason to cause the risk 對某一海上邊際油田的開發進行了示例分析,計算結果表明,邊際油田的開發具有很高的風險,而投資費用、石油價格以及可采儲量的不確定性是引起開發風險的主要因素。

The remaining recoverable reserves are a material base for future development of oil and gas fields , and the reserve - production ratio is a specific index to analyze and judge future development trends of oil and gas fields 摘要剩馀可采儲量是油氣田未來開發的物質基礎,儲采比是分析和判斷油氣田未來開發形勢的特殊指標。

This model provides theoretical basis for rational development of similar reservoirs and improved the calculation method of technical recoverable reserves of heavy oil reservoirs in liaohe oil province 該模型為同類型油藏的合理開發提供理論依據,并完善了遼河油區稠油油藏技術可采儲量計算方法系列。

The technical recoverable reserve of developed ultra heavy oil reservoir is obtained by using iterative method and mathematical model 采用迭代法,通過數學推導,得到已開發超稠油油藏的技術可采儲量。
