摘要
为了快速、准确、有效地评价储层的敏感性 ,在岩心分析资料的基础上 ,提出了用测井方法评价储层敏感性。从测井信息中提取出石英骨架、长石骨架、岩屑骨架、泥质、蒙脱石、伊利石、高岭石、粒度中值、综合物性参数、孔隙度、渗透率等 1 1个参数 ,经过岩心标定后 ,都可由测井信息处理获得。以这些参数为基础进行储层敏感性与各参数的相关性分析 ,提出了用理论排序表和相关性系数加权的方法来实现测井方法预测储层的敏感性。应用该方法对某油田进行了处理分析 ,结果表明由测井处理得到的速敏、水敏、盐敏。
In order to quickly,accurately and effectually evaluate the reservoir sensitivity,on the base of the data of core analysis,the method of well logging was put forward to evaluate the reservoir sensitivity.The eleven parameters have been obtained from well logging information such as quartz,feldspar,rock fregments,clay volume,montmorillonite,illite,kaolinite,medium granularity value,general poro perm parameter,porosity,permeability and etc They can be received from well logging data after these parameters are Scaled by core data.On the base of these parameters,the relativity analysis of reservoir sensitivity and its factors were studied,then the theoretical compositor table and the method of relativity regression coefficient were put forward to predict reservoir sensitivity in the means of well logging.The method was put into use to evaluate reservoir sensitivity in the studied oilfield,and the processing results showed that the fluid velocity sensitivity,salt water sensitivity,fresh water sensitivity,alkali sensitivity and acid sensitivity were consistent with the core fluid sensitivity test results,which came from well logging method.It is a great aid to mud content design,industrial net pay finding,and reservoir protection in time.
