喇嘛甸油田气顶气藏经济可采储量评价与风险分析

根据喇嘛甸油田气顶气藏储集层特征和构造研究结果,利用现金流量法预测了喇嘛甸油田气顶气藏经济可采储量和经济采收率;同时利用概率分布法对证实储量、概算储量及可能储量的三种经济可采储量进行了风险性评价和不确定性因素分析.研究表明储量价值最敏感的因素是产量,气价、成本影响不是太大,这为该气藏科学开发提供了重要的理论依据.

Evaluation and venture assesment of the economic recoverable reserves of the gas-cap reservoir in Lamadian Oilfield

The economic recoverable reserves and the economic recovery factor of the gas-cap reservoir are predicted by using cash flow method based on the studies of characteristics and the tectonic of the gas-cap reservoir of Lamadian Oilfield.At the same time,the risks of the proven reserves,probable reserves and possible reserves and the uncertain factors of influencing them are analyzed using the probability distribution method.The results show that,gas yield is the most sensitive factor to the reserves values,and the price and the production cost of the natural gas are secondary sensitive factors,which provides important theoretical basis for the scientific development of the gas-cap reservoir.uncertainties of economic recoverable reserves in this paper.
