确定裂缝性火山岩储集层孔隙容积的油藏工程实用方法

提出了应用试油阶段压力恢复试井和产量、流压矿场测试资料，采用Pollard-Pirson 方法和影响函数法，确定裂缝性火山岩油藏单井泄流范围内的裂缝、基质孔隙容积。提出的方法有效弥补了非均质性十分严重的裂缝性火山岩油藏现有确定裂缝、基质孔隙容积方法所存在的理论和技术上的局限性，对于进一步研究裂缝性火山岩油藏地质、油藏工程和产能特性有较好的理论和实际应用意义。

The Practical Reservoir Engineering Methods for Determination of Porosity Volumes in Fractured Volcanic Reservoirs

The buildup test data and field flow pressure information during production test are used to ascertain the fracture and matrix porosity volume within single well drainage area in fractured volcanic reservoir by means of Pollard-Pirson and influence functions methods. The results show that these methods can be applied to effectively make up the theoretical and technical limitations appeared in existing methods for ascertaining fracture and matrix porosity volumes in fractured volcanic reservoirs. It is significant to further study the reservoir geology, reservoir engineering and productivity performance in fractured volcanic reservoirs.
