摘要
江汉盆地潜江凹陷潜江组砂岩中蕴藏着丰富的卤水资源,卤水品质好,有多个矿种达到了综合利用工业品位,其中溴的品级系数高达6.1。利用测井资料有效识别砂岩卤水矿床是卤水勘探开发的基础。通过测井、试采、分析化验等资料研究深层卤水的岩性、物性、含卤性与测井之间的关系,确定有效卤水层解释标准,建立孔隙度、渗透率及卤水产能模型。
The sandstone of Qianjiang Formation, Qianjiang Depression, Jianghan basin is rich in brine minerals of fine qualities, quite a few of which are valuable for commercial utilization with the grade coefficient of Bromine being as high as 6.1. The identification of brine minerals with logging information is the basis of brine exploration and development. By use of well logging, production test, and analytical data, this paper studies the relationship between lithology, physical properties, mineral content, and logging information, establishes an interpretation standard of effective brine bed, and sets up models of porosity, permeability, and brine productivity.
