针对林樊家地区馆陶组河道砂岩储层及其含油性展开描述与评价,依据实钻井的钻、录、测、试及地震振幅能量,以及大量的地质统计分析,采用“振幅极值滤波”技术确定出研究区岩性、厚度、物性与地震波振幅之间的关系。运用储层含油气后频率吸收原理,提出敏感属性,优选衡量频率变化的含油性预测技术,开展浅层河道砂体的地震描述和含油性预测,取得较好的应用效果。
In view of the description and evaluation of the Guantao Formation channel sandstone reservoirs and their oiliness in the Lin Fanjia area, based on the drilling, recording, testing, testing and seismic amplitude energy of actual drilling and a large amount of geostatistical analysis, Filter "technology to determine the relationship between lithology, thickness, physical properties and seismic amplitude in the study area. Based on the principle of frequency absorption after reservoirs containing gas and oil, the paper proposes the sensitive properties, optimizes the oil-bearing prediction technique to measure the frequency variation, and carries out the seismic description and oil-bearing prediction of shallow channel sand body.
