摘要
依据泥质岩盖层封闭油气的机理，选取与泥质岩盖层质量相关的测井信息，以实验分析地层岩样为基础，经岩电归位后，运用计算机进行回归─拟合，选取最佳数学模型，利用测井信息计算泥质岩盖层的突破压力和储层的排替压力等评价参数。同时根据油气在地层中运移、渗滤的条件建立了相应的定量评价参数标准。在吐哈盆地的盖层研究中应用效果良好。
According to shaly rock sealing mechanism for oil and gas, this paper presents a quantitative logging evaluation of cap rock quality through choosing log data related to shaly cap rock quality, and builds up the optimum mathematical model to obtain the standard cap quality evaluation parameters, such as breakthrough pressure and displacement pressure, bases on the experimental analysis of rock specimen. The desired results have been obtained in cap rock study for Turpan-Hami basin.
