塔北地区储层敏感性综合预测

综合分析地质、地震及测井资料，可以准确地预测储层的敏感性。以地质分析及敏感性实验资料为基础，以测井资料为标定手段，以地震信息为横向预测导向，综合处理各种信息，从而实现对区域储层的敏感性预测。其中，利用测井资料预测储层敏感性是关键，须采用多参数相关系数法进行单井储层敏感性分析。以塔北地区侏罗系为例，综合各类信息进行了储层敏感性处理，分析结果表明，该区储层速敏弱，水敏、盐敏、碱敏和酸敏程度中等，与其储层敏感性实验结果基本吻合。

Comprehensive prediction of formation sensitivity in Tabei Area

Formation sensitivity can be predicted exactly with comprehensive analysis of geological,seismic and well logging data. Based on geologic analysis and sensitivity test data, the regional formation sensitivity can be predicted by comprehensive treatment information of well - log and seismic information. The well - log information is the key of predicting the formation sensitivity. The formation sensitivity of single well may be analyzed using multi - parameters correlation coefficient method. Taking Jurassic of Tabei Area as an example, the formation sensitivity is treated using each types of imformaiton. The results show that velocity sensitivity is weak,water,salt,alkani and acid sensitivity are medium, which is almost the same as the experimantal results of its formation sensitivity.
