摘要： 为了解决惠州凹陷X构造潜山岩性复杂、流体类型多样、含油气丰度评价标准不一等问题,基于已钻潜山井的岩石薄片鉴定及元素录井资料,对研究区潜山储层复杂岩性的镜下微观成分、结构及构造特征进行梳理,优选特征元素Si、Fe、Mg含量建立复杂岩性识别图板,形成了适用于研究区潜山复杂岩性的快速识别方法;基于FLAIR流体录井资料,优选出表征轻质油和凝析气烃组分差异的参数C₁相对含量和Q'值对轻质油层和凝析气层进行区分,结合校正值单位岩石甲烷气体体积与C₁异常倍数建立解释图板识别油气层和干层。经后续的分析化验及取样、测试等资料验证,该方法在潜山复杂岩性识别中准确率可达93.8%,流体解释评价符合率为89.5%,在随钻过程中可以为复杂岩性的判断与流体评价提供理论依据,对下步地质作业方案制定及勘探作业降本增效起到指导作用,具有较强的推广应用价值。

Abstract: In order to solve the problems of complex lithology, diverse fluid types, and inconsistent evaluation standards for hydrocarbon-bearing abundance in the X structure buried hills of Huizhou depression, based on the petrographic thin section analysis and element logging data of the drilled buried hill wells, the microscopic composition, framework and structural characteristics of the complex lithology under the microscope for the buried hill reservoirs in the study area were sorted out. Select the content of Si, Fe and Mg feature elements to establish the complex lithological discrimination charts, forming the fast identification methods suitable for the complex lithology of buried hills in the study area. On the basis of FLAIR fluid logging data, C₁ relative content and Q' characterizing the differences in hydrocarbon components between light oil and condensate gas were optimized to distinguish the light oil layers and condensate gas layers. Combined with the correction value for methane gas volume per unit rock and C₁ anomaly multiple, the interpretation charts were set up to identify light oil layers, condensate gas layers and dry layers. The methods have been applied in buried hills, with the accuracy of 93.8% in identifying complex lithology and a fluid interpretation and evaluation coincidence rate of 89.5% after subsequent analysis, sampling, testing and other data verification. During the drilling process, the methods can provide theoretical bases for the judgment of complex lithology and fluid evaluation, and guide the further making geological operation plan and reducing costs and increasing benefits in exploration operation, with stronger application value.
