罗家地区页岩油气测井评价方法

页岩油气已成为中国能源新的增长领域。为了建立针对页岩油气的测井评价方法,以胜利油区罗家地区重点探井罗69井为例,系统研究了泥页岩的岩相、储集空间类型、物性、含油性及测井响应特征。研究结果表明,该类地层孔隙性越好,含油性越好。在此基础上,构建了泥页岩中钙质、石英、粘土等矿物组分含量及孔隙度、含水饱和度、总有机碳含量等评价参数的定量计算模型;进一步根据不同层段的含油气品质,将泥页岩地层划分为4类,其中Ⅰ类层含油气性最高,主要为纹层状泥质灰岩相。该测井评价方法有效地辅助了胜利油区罗家地区泥页岩水平井渤页平1、渤页平2、渤页平3井的部署,目的层良好的油气显示也进一步验证了该评价方法的实用性。

Logging evaluation method of shale oil and gas reservoir in Luojia area

Shale oil and gas has become new energy growth area in China. In order to establish the well logging evaluation method of this kind of reservoir, taking the exploration well Luo 69 of Luojia area as example, the shale lithofacies, reservoir space type, physical properties and oiliness are systematically analyzed, and the logging parameter quantitatively models including mineral constituent of calcium, quartz, and clay content, and porosity, water saturation and total organic carbon are also established. urthermore,the shale formation is divided into four types based on the varied oil and gas quality, in which, the type I is of the best oil quality. This research provides an effective reference for the deployment of the first shale horizontal well in Shengli Oilfield, and achieves a good result. It can provide reference for todays shale oil and gas exploration.
