未开发储量价值量评价思路及方法

Evaluation thoughts and methods in the undeveloped reserves value

通过对注水开发油藏井网密度与单井增加可采储量关系特征分析,建立了未开发储量或新探明储量品位特征值计算模型,论证了储量品位特征点及其与主要地质参数的关系.结合一定经济条件下新钻井增加可采储量经济界限要求,建立了反映储量静态价值量分布的计算模型,提出了评价储量品位及价值的新方法.

The model for calculating the characteristic value of the quality of undeveloped reserves or newly proven reserves is established based on the analysis of the relationship between well spacing density and an increase in single-well recoverable reserves of water-flooding reservoirs,and the characteristic points of the reserve quality and their relations with main geologic parameters of reservoirs are discussed.The model reflecting the distribution of reserves static value is established according to economic limit requirement of the increase in the recoverable reserves of a new well under certain economic conditions.A new method for evaluating the quality and value of reserves is presented.
