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 development of petroleum industry and continuous exploration and development, the tight sandstone reservoirs with low porosity and low permeability have gradually become the focus and focus of oil and gas exploration and development. The evaluation of such reservoirs is also well logging interpretation and reservoir evaluation Difficult problems. The research on the relationship between the four reservoirs, the establishment of pore-infiltration parameter model and the calculation of relevant parameters are the keys to evaluate this kind of reservoir. According to the reservoir geological characteristics of the study block, the reservoir quaternary relationship was studied and the parameters of the rock electrical parameters were obtained. Finally, the porosity, permeability and water saturation interpretation models were established and validated according to the actual situation. Layer logging interpretation and reservoir evaluation.
