摘要
通过施工油页岩参数孔,获得油页岩测井与测试数据,在分析油页岩测井曲线响应特征的基础上利用在鱼卡煤田施工的Y-1Y孔资料建立基于ΔlogR模型的油页岩测井解释模型,并在鱼卡、团鱼山、全吉山地区施工钻孔进行验证。验证结果表明,利用油页岩测井模型预测的含油率与实测含油率接近,并与有机质的含量(TOC)高度相关,预测结果较为可靠。利用该模型对以往煤炭钻孔测井资料进行二次开发,可以获得厚度、埋深和含油率等与油页岩评价相关的参数。
Through oil shale parameter boreholes construction, have obtained oil shale well logging and testing data. On the basis of oil shale well logging traces response features analysis using data from borehole Y-1Y in the Iqe coalfield have established oil shale well logging interpretation model based on ΔlogR model, and carried out validation in boreholes drilled in Iqe, Tuanyushan and Quanjishan areas. The validated results have shown that using oil shale well logging model predicted oil content is close to measured oil content, and highly correlated with organic matter content （TOC）, thus the predicted results are rather reliable. Using the model carried out secondary study for previous coal borehole well logging data thus can obtain thickness, buried depth and oil content parameters related to oil shale assessment.
