Key Parameterand Calculation in Shale Oil Reservoir Evaluation

摘要

摘要: 随着非常规油气勘探的进一步深入，页岩油气逐渐成为现今勘探研究的热点和难点。目前国内针对页岩油的勘探开发没有成功的案例可循，实际工作中一直沿用了国外页岩气的勘探及评价思路。通过研究指出，页岩油自身的特点决定了其勘探不能照搬国外的页岩气评价思路，将研究重点仅仅停留在有机碳含量上无法满足勘探需要，页岩油勘探的核心问题在于地层已生成的游离烃含量的评价。利用胜利油区第一口页岩密闭取芯井分析化验资料为基础，系统研究了孔隙度与单位含油体积以及含水体积之间的关系，发现了烃源岩中孔隙性越好，含油性越好的特点。利用孔隙度、含油饱和度等岩心分析数据推导出了反映泥质页岩游离烃含量的评价模型，并构建了基于实测的深侧向电阻率、孔隙度、有机质成熟度等参数的求取模型。利用页岩地层游离烃中有机碳含量和总有机碳含量对比可以直观反映地层中游离烃含量的垂向变化规律，指示页岩层段的有利油气区段。以胜利油田沾化凹陷罗家地区罗69井实验分析资料为例，对模型的参数求取及效果分析进行了阐述，构建的地层有机质成熟度模型及游离烃中有机碳含量均精度较高，在此基础上，通过游离烃有机碳含量绝对值、以及游离烃中有机碳含量与地层有机碳含量的比值实现了对页岩油地层可动油气富集带的指示，可动油气相对富集的层段即为页岩油地层的勘探目标。该思路可为目前的陆相页岩油勘探提供借鉴和参考。

Abstract: Research indicates that focus merely on the organic carbon content can not meet exploration needs because the characteristics of the shale formation. The most important issue of the exploration is to evaluate the free hydrocarbon content in shale formation. The relationship between porosity and oil volume in per cubic meter of rock and the relationship between porosity and water volume in per cubic meter of rock have been studied. The result shows that in the oil source rock, the characteristics of oil-bearing is increasing with the increasing of rock porosity.
On basis of the analysis of closed cored laboratory data such as the porosity and oil saturation in Shengli Oil field, an new evaluation model is constructed to reflect the free hydrocarbon content. And the logging interpretation model has also been established by using the deep resistivity curve response value, porosity and the organic matter maturity to calculate it. The ratio of organic carbon content from free hydrocarbon and total organic carbon content can directly reflect the vertical variation regulation of the free hydrocarbon content, which also indicates the favorable oil and gas exploration section. An example from Luojia area in Zhanhua sag has been reprocessed . A new model of the organic matter maturity was derived based on the experimental data and the depth. The calculating result shows a good application of this method. The indicator of free hydrocarbon enrichment zone can be derived by combining two parameter.
One is the absolute value of organic carbon from free hydrocarbon, the other is the value between absolute value of organic carbon content from free hydrocarbon and the total organic carbon content. The section with high ratio will be the exploration targets of shale oil reservoir. This idea can provide reference for today’s shale oil and gas exploration.
