YWM区长4+5、长6储层敏感性评价

Sensitivity evaluation on Chang 4+5 and 6 reservoirs in YWM block

为高效开发鄂尔多斯盆地YWM地区的超低渗储层,本文对该区的长4+5、长6储层敏感性评价进行了描述。结果表明,该地区储层具有弱水敏、弱速敏、弱碱敏的特点。

The sensitivity of Chang 4＋5 and 6 reservoirs were evaluated in this article for efficient development of ultra-lowpermeability reservoir in YWM,Ordos Basin. The results show that the reservoir in this block feature weak water sensitivity,lowvelocity sensitivity,and base sensitivity.
