A油田三叠系储层敏感性研究

根据岩石薄片、铸体薄片、X-衍射、压汞、地层水矿化度等资料，对影响A油田三叠系储层敏感性的粘土矿物特征及粘土矿物与储层敏感性的关系，进行较为深入的研究。在此基础上提出了单相关系数加权的储层敏感性预测方法，总结了理论排序表。用该方法所预测的储层敏感性与岩心流动实验结果基本符合。这与直接应用粘土矿物等资料进行定性分析同样可靠、符合实际，因此大大节省岩心敏感性流动实验的费用和时间，对油田勘探开发中的油气层保护具有重要意义。

Reservoir Sensitivity Study of A Oilfield Tertiary Formation

Based on the thin slice,cast slice,granularity analysis,mercury injection,micros canning,porosity and permeability analysis,X ray analysis,core flui d sensitivity tests,and etc,this paper deals with various characters and clay mi neral character of the oilfield tertiary formation.A new theoretical table is pu t forward,and a new single variable regression coefficient method is put forward at the same time,which is used to predict reservoir sensitivity.The obtained re sults show that the reservoir sensitivities are consistent with the core fluid s ensitivity test results.These results are as convincible and feasible as the res ults obtained by clay mineral analysis,and can save the cost and time of core fl uid sensitivity experiments,which is very valuable to reservoir protection in th e process of oil exploration and exploitation.
