摘要
通过储层测井响应特征提取地质信息 ,判断沉积环境和储层的空间几何形态 ,分析影响油气运移的因素 ,为油气田的勘探、开发部署提供有力的依据。该工作中利用研究区内 14口井的测井精细解释成果 ,从沉积地层、沉积环境、古水流方向、砂体加厚方向、地层应力方向、裂缝发育程度等方面入手 ,进行了全面的地质分析 ;得出了研究区内的沉积相组合、河床特征、古水流能量、裂缝发育规律及地层应力方向。分析了沉积环境、储层展布、储层物性及储层产能之间的密切关系 。
Geologic information from log responses of reservoirs helps judge the deposits and spacial geometries of reservoirs, analyse the factors effecting the transmigration of oil & gas so as to provide more information for reservoir exploration & development plans. On the basis of the fine interpretations of 14 wells in the areas studied, depositional facies, channel beds, palaeocurrent energy, fracture growth and direction of the crustal stress are identified by analysing sedimentary formation, deposits, palaeocurrent direction and the sand thickening direction, etc.. Relationship among deposits, geometries, physical property and productivity of reservoirs is given. Oil gas rich zones are evaluated.
