Comparison and Study over the Biot Coefficients Test Methods in Medium Porosity and Medium Permeability Sandstone Reservoirs
-
摘要: Biot系数是流-固耦合理论的核心参数，但目前缺乏针对特定储层的准确获取Biot系数的推荐方法，为此通过室内试验对比研究了3种可用于中孔中渗砂岩储层的Biot系数测试方法——Cross-plotting法、排水试验法和声波动态法。以胜利油田典型砂岩区块为例，分别从渗透理论、岩石弹性变形特性与声波动态分析3方面入手，进行了试验研究，比较了试验结果，探讨了影响试验结果的因素。试验发现，利用Cross-plotting法获取的Biot系数最大，利用排水试验获取的Biot系数次之，利用声波动态法获取的Biot系数最小，并且动态测试值要明显小于静态测量值。研究认为，对于中孔中渗砂岩，推荐采用基于岩石弹性变形理论的排水试验法，该方法测试精度高、可靠性强。Abstract: The Biot coefficient is the core parameter of the fluid-solid coupling theory,but currently there is a lack of recommended methods for accurately obtaining the Biot coefficient for specific reservoirs.To solve the problem,a comparison and study of three kinds of Biot coefficient test methods for medium porosity and medium permeability sandstone reservoirs have been conducted in the laboratory,including the Cross-Plotting method,the drainage test method and sonic wave dynamic method.Taking the typical sandstone block in Shengli Oilfield as an example,the experimental study was carried out in three aspects,i.e.permeation theory,rock elastic deformation characteristics and acoustic wave dynamic analysis.The experimental results were compared and the factors affecting the experimental results were discussed.It was found that the Biot coefficient obtained by using the Cross-plotting method was the largest,the Biot coefficient obtained by a drainage test was the second,and the coefficient obtained by using acoustic wave dynamic method was the smallest.The dynamic test value was significantly smaller than the static measurement value.Study results indicate that the drainage test method based on rock elastic deformation theory is recommended for medium porosity and medium permeability sandstone reservoirs,because it has high accuracy and strong reliability.
