对油气储层的产能进行定性或定量评价一直是勘探开发的一项基本任务。针对徐深气田兴城地区火山岩储层类型多样,孔隙结构复杂,储层非均质性强的特点,在对研究区火山岩储层地质及试气资料分析的基础上,应用常规和成像测井资料,论述了总孔隙度、次生孔隙度、次生发育厚度、孔洞裂缝发育程度等参数与产能的关系。并利用上述参数建立了火山岩储层产能评价标准。在实际应用中取得了比较满意的效果,对今后天然气火山岩储层的产能预测和气田开发部署具有较高的参考价值。
The qualitative and quantitative evaluation of oil and gas reservoir production capacity has always been a basic task of exploration and development. According to the characteristics of volcanic reservoirs of Xingcheng area in Xushen gas field, the pore structure is complex and the reservoir heterogeneity is strong, based on the analysis of the volcanic reservoir geology and gas test data in the study area, conventional and imaging logging Data, discusses the relationship between total porosity, secondary porosity, secondary growth thickness, porosity development degree and other parameters and capacity. Based on the above parameters, the evaluation standard of volcanic reservoir productivity is established. It has obtained satisfactory results in practical application and has a high reference value for future production prediction of natural gas volcanic reservoirs and gas field development and deployment.
