H地区隔夹层对油水界面的影响分析

Effect of interlayer on the oil-water interface of H area

H油田B油藏的目的层段发育着不同类型的隔夹层,其在空间上的分布也有一定的规律.以测井响应特征分析为基础,研究了H油田B油藏目的层段隔夹层的分布规律,发现在B油藏D砂岩段中的7号砂组隔夹层对油层底部的水层有一定的封堵作用,造成油水界面的不统一.研究结果对H油田进一步的储层评价具有重要意义.

The objective intervals of reservoir B in H Oilfield develop different types of interlayers and its distribution in space also has certain rules. We analyzed distribution law of interlayers on the logging response characteristics analysis as the foundation and got a conclusion that the 7th group interlayers of the sandstones D in H Oilfield had a certain extent blocking effect to the water layer in the bottom of the oil layer and caused non-uniform in oil-water interface. The research results have important significance for further evaluation of reservoir in H Oilfield.
