华庆地区长6储层敏感性特征分析

Sensitivity Analysis of Chang 6 Reservoir in Huaqing Area

华庆地区是长庆油田2009年投入开发的一个新区块,为使区块合理高效的投入开发,就必须掌握储层敏感性特征。利用岩心薄片及X衍射分析了长6储层潜在伤害的矿物成分,使用流动实验评价了储层的敏感性特征。研究结果表明,长6储层敏感性特征表现为弱水敏、弱～中等酸敏、弱盐敏、弱速敏、弱碱敏。

Huaqing area is a new block invested and developed by Changqing oilfield company in 2009,to realize reasonable and effective development of the block,it is necessary to master sensitivity characteristics of the reservoir.In this paper,potential harmful mineral composition of Change 6 reservoir was analyzed by using core wafer and X-ray diffraction,and sensitivity characteristic of the reservoir was evaluated by using flow experiments.The results show that Chang 6 reservoir sensitivity is weak water sensitivity,weak ~ medium acid sensitivity,weak salt sensitivity,weak speed sensitivity and weak alkali sensitivity.
