低渗透气田相对高渗储层描述方法研究——以苏里格气田为例
|
摘要
有效开发低渗透气田的一个重要地质问题就是如何预测相对高渗储层的分布。以苏里格气田为例,综合储层岩石学、测井和地震等信息,分析总结了相对高渗储层的微观特征及测井、地震的响应特征;提出了应用沉积相二级成图、次生孔隙测井识别、砂体叠置规律研究、AVO分析及相控随机建模技术进行低渗透背景下相对高渗砂体的描述及预测方法。文章总结的辫状河沉积环境下的相对高渗储层展布规律对指导苏里格气田有效开发提供了很好的地质基础,同时也为类似低渗透气田相对高渗储层的描述提供了借鉴。
The key to develop tight gas reservoir was to find out the relative-high permeability reservoirs.By taking Sulige Gas Field for example,one of it was investigated in this study and the information from reservoir lithology study,well log and seismic data were combined to make an comprehensive analysis of relative-high permeability reservoir,including microscopic features and response characteristics of well logs and seismic tests.The combination of secondary sedimentary-facies-restitution,well log identifying induced porosity,sand superposition law research,AVO analysis and facies-controlled-stochastic modeling was suggested to predict relative-high permeability sandbodies.As the outcome of this research,the distribution law of relative-high permeability reservoir derived from braid rivers may provide a sound support for effective development of Sulige Gas Field.It could also be introduced to guide the development of similar gas fields.
