兴城地区火山岩储层孔洞裂缝发育与产能关系研究

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。

On the Relation between Pre-fracture Growth and Productivity of Volcanic Reservoir in Xingcheng Area

Qualitative or quantitative evaluation of productivity for oil and gas reservoirs was a basis task for oil exploration and development. In allusion to the characteristics of multi-types, complex pore structures, strong reservoir heterogeneity of volcanic reservoirs in Xfingcheng Area of Xushen Gas Field, on the basis of analyzing the geology of volcanic reservoir and gas test data, the total porosity, secondary porosity, the secondary thickness, the range of pore and fracture were denoted by using conventional and imaging logging data. A criterion was established for productivity evaluation of volcanic reservoirs by using the parameters stated above. It is used with satisfied result, it is a valuable reference for productivity prediction and arrangement of gas field development for volcanic reservoirs.
