岩心裂缝重定向的古地磁方法研究
|
摘要
裂缝信息对于低渗透储层的勘探开发具有重要意义。本文在深入探讨利用古地磁方法进行岩心裂缝重定向原理的基础上,详细介绍了岩心裂缝重定向的工作方法。针对垂直及平行于岩心中心轴的两种样品加工方式,推导出可直接利用退磁结果表达的裂缝方向的公式,并将这一结果应用于鄂尔多斯盆地一口有裂缝井的岩心,取得较好的应用效果。研究结果表明,利用古地磁方法进行岩心裂缝重定向具有操作简便、成本较低、且精度相对较高的特点。本文研究结果对于鄂尔多斯盆地的裂缝系统研究具有参考意义。
The crack information is of great significance for the exploration and development of lowpermeable reservoirs.After principle of reorientation core-cracks with paleomagnetic method was discussed,the operational approach of that was introduced specially.According to vertical and parallel drilling ways of samples,formulas for crack-redirection were elicited with the results of demagnetization.And the method was applied to the cores of a fractured well in Ordos Basin and achieved good results.The research shows that using paleomagnetic method to redirect cores-cracks has the characteristics of easy operation,low cost and high precision.At the same time,the research is reference for the study of Ordos Basin cracks.
