摘要
随着石油行业的快速发展和勘探开发的不断深入,低孔低渗的致密砂岩储层逐渐成为油气藏勘探与开发的热点和重点,对该类储层的评价也是测井解释与储层评价的难点问题。储层四性关系的研究、孔渗参数模型的建立及相关参数的求取,是评价该类储层的关键。针对研究区块的储层地质特征,进行储层四性关系研究,并求取岩电参数,最后根据实际情况建立孔隙度、渗透率、含水饱和度解释模型并进行了验证,为该类储层的测井解释与储层评价提供参考。
With the rapid expansion of petroleum industry and the deepening of exploration and production, the tight sandstone reservoir with low porosity and permeability gradually becomes the focus and emphasis, and it＇s also a challenge for logging interpretation and reservoir evaluation. In order to evaluate this kind of reservoir, it is impor- tant to study on four properties＇ relationship as well as build interpretation models＇ of porosity, permeability and sat- uration with related parameters. According to the properties of the field, reservoir＇s four properties＇ relationship and rock -electro parameters has been obtained, interpretation models＇ of porosity, permeability and water saturation has been built and proved, which provides some references in reservoir evaluation of tight sandstone.
