储层的敏感性与储层砂岩中粘土矿物成份、含量及储层流体性质密切相关，它在油田开发过程中起着重要的作用。
The reservoir sensitivity is closely related to clay mineral contents in sandstone and fluid properties of reservoir, which plays an important role in oilfield development.
分析表明，储层填隙物中的粘土矿物、碳酸盐矿物是导致该区储层敏感性的主要因素。
Shown by analysis, the main factors causing the reservoir sensibility in this area are clay minerals and carbonate.
但是，对于某些粘土含量高，敏感性强的致密油气藏，采用水力压裂技术改造尽管能获得工艺上的成功，但是最终增产效果却大打折扣。
However, for some special reservoirs with high clay content and sensitivity, the final effictiveness is greatly reduced although hydraulic fracturing process can be successful.
