利用P油气田F构造F1断块上钻探的6口开发井的测井、测试等资料,本文对原油藏描述中关于储集砂体的研究解释进行了验证,作了新的认识。提出:(1)原标定的六个油气层的地震层位和极性基本与钻井吻合。(2)由于地震速度谱点间隔太大,无法控制地层速度横向变化,造成构造形态有所失真。

Based on the data of the logging and thesting of the 6-exploratory wells drilled in the F1 fault block,this paper has verified the series of top-structure-map of Sandstone made in the reservoirdescription. Some new knowledge have been achieved:(1) The original 6 seismic horizons marked by reservoir and their polarities basically coincide with the drilling data.(2) The distance between the spots of the velocity spectrum is too large to control the lalend variety of interval velocity, and cause the shape of the structure inconsistent with the facts.
