摘要/Abstract

摘要： 火山岩油藏属于双重介质油藏，油藏内部天然裂缝发育，由于储层具有应力敏感性，火山岩油藏产量受地层压力变化影响明显，且储层流体流动具有启动压力梯度现象，故目前没有适合火山岩油藏特性的产能模型。基于双重介质模型，分区（基质-裂缝区、缝网改造区、部分缝网改造区、人工裂缝区）建立了火山岩油藏压裂水平井渗流模型，通过Laplace变换、Duhamel原理和叠加原理得到了拉氏空间压裂水平井复合流动模型，利用stehfest数值反演得到了相应的压力动态响应曲线和无量纲产量曲线，并对影响产能的部分因素进行了敏感性分析。结果表明：压裂改造区的宽度和长度等主要影响中间流动阶段，未压裂改造区的宽度、长度、非达西流动和应力敏感性主要影响后期流动阶段。利用建立的复合流动模型准确地预测了无底水火山岩油藏产能，此项研究对于火山岩油藏产能计算具有一定的指导意义。

Abstract: Natural fractures are developed in the volcanic reservoirs which are dual medium. Due to the stress sensitivity of the reservoirs,the production of volcanic reservoirs is significantly affected by changes in formation pressure,and there is a threshold gradient pressure phenomenon,so there is currently no productivity model suitable for the characteristics of volcanic reservoirs. Based on the dual media model,a coupling multi-scale（matrixfracture zone,fracture network reform zone,partial fracture network reform zone,artificial fracture zone）seepage model of fractured horizontal wells in volcanic reservoir was established,which was solved by Laplace transformation,Duhamel principle and superposition principle in Lagrangian space. The corresponding pressure dynamic response curve and dimensionless production curve were obtained by Stehfest numerical inversion,and the sensitivity analysis of different influencing factors was performed. The results show that the width and length of the fractured zone mainly affect the intermediate flow stage,while the width,length,non-Darcy flow and stress sensitivity of the unfractured zone mainly affect the later flow stage. The established compound flow model can accurately predict the productivity of bottomless volcanic reservoirs. There is certain guiding significance for the calculation of productivity of volcanic reservoirs.

Key words: volcanic rock, compound flow model, production calculation, sensitivity analysis
