高尚堡油田明化镇组层序界面的识别及岩性圈闭预测
【摘要】 以高精度层序地层学理论为基础,结合测井曲线和地震解释对高尚堡油田新近系明化镇组储层的层序界面进行精细划分。将明化镇组储层划分为1个长期旋回、4个中期旋回、15个短期旋回,建立了符合实际情况的地质模型。绘制层序三砂泥比等值线图揭示出有利的岩性圈闭区是在基准面上升期间形成河道下切,下降期间能够形成泥质封盖的区域。
【Abstract】 Base on the high resolution sequence of straigraphy,analysis rock cores,well logs and seismic data,the resorvior of minghuazhen formation in Gaoshangpu oil fields would be divided into one long-term cycle,four middle-term cycle and fifteen short-term cycle,establish a reasonable geology model.Drawing the equivalent line diagram of sand to mire of sequense III,to recover the beneficial lithologic trap is a restrict where it become the course of river in the base level under slice in the rise period,can become the district of the mire cover in the decent period.
【Key words】 high resolution sequence of straigraphy base-level cycle lithologic trap;
