西阿纳达科盆地上Morrow砂层的地震显示 Jens R.等郭路平译在西阿纳达科盆地,下宾夕法尼亚组的上 M-orrow 砂层是一个既多产又难以捉摸的勘探层。其中有些砂层的最初石油产量可达1000多桶/天·井但是在偏离生产井350米的井中却见不到 Morrow 砂层,所以出现了干井。文章利用了一维综合测井模拟、二维测井内插模拟、彩色地震反演处理及地震相绘制技术,研究了得克萨斯 Panhandle 地区的Lear 和 Darden 油田及两组上 Morrow 砂层。该地区 Morrow 砂层在2500到3000米深度处厚度约达10到15米。这些 Morrow 砂层位于薄层范围内(在调 Earthquakes in the Morrow Sandstone on the Western Anadarko Basin show Jens R. et al. In the West Anadarko Basin, the lower M-orrow sandstone in the Lower Pennsylvania Formation is a productive and elusive exploration layer. Some of these sand layers initially produced more than 1,000 bbl / d of oil but did not see the Morrow sand in a well that deviated 350 m from the production well, resulting in a dry well. In this paper, the Lear and Darden oilfields in Panhandle, Texas and the Morrow sandstone in both groups are studied using one-dimensional integrated logging simulation, two-dimensional logging interpolation modeling, color seismic inversion processing and seismic facies rendering techniques. The Morrow sand layer in the area is about 10 to 15 meters thick at depths of 2500 to 3000 meters. These Morrow sand layers lie in a thin layer (in tune
