南方海相富有机质页岩电性特征及勘探意义
|
摘要
页岩气作为一种清洁环保的新型能源,具有极大的开发潜力。我国的页岩气储量在世界范围内所占的比重约为15%左右,尤其是南方地区成藏条件优越,发育多套海相页岩层,每层的有机质含量丰富,是研究页岩气勘探与开发的有利远景区。近年来,受近地表的地质构造及地形条件影响,地震勘探的效果不佳。因此,针对地震页岩气富集层位即"甜点区"的判断,基于富有机质页岩的电性特征展开研究,采用储层描述提取属性参数方法,进行页岩气储层解释电法勘探。
As a clean and environmental friendly new energy, shale gas has great potential for development. China's shale gas reserves account for about 15% of the world's total, especially in the southern region, there are superior reservoir conditions and multiple marine shale formations are developed. The rich organic matter content in each layer is a favorable perspective for the study of shale gas exploration and development. In recent years, under the influence of the geological structure and topographic conditions near the surface, the effect of seismic exploration is not good.Therefore, based on the judgment of the seismic shale gas accumulation horizon, namely the "dessert area", the study on the electrical characteristics of the organic shale was carried out, and the reservoir description and extraction of attribute parameters were adopted to conduct the electrical exploration of shale gas reservoir interpretation.
