| 摘 要： | 玉北地区经历过多期构造运动,构造复杂,储层非均质性强.在总结断洼带地层的基础上,针对奥陶系一间房组和鹰山组灰岩段,通过对比断垄带、斜坡和断洼带地层整体电阻率的大小及地震相干特征,研究井位与储层发育之间的关系;结合常规、成像和测试等相关资料分析鹰山组云灰岩段和蓬莱坝组白云岩化程度与储层之间的关系.研究结果表明该地区上部一间房组和鹰山组灰岩段,断垄带的储层较发育,斜坡和断洼带储层基本不发育;鹰山组云灰岩段和蓬莱坝组储层白云岩的发育程度相关.

| Abstract: | After multiple stages of tectonic movement, the Yubei area is featured by complicated tectonic pattern and strong reservoir heterogeneity. Based on the formation evolution in depression area, it was analyzed in this article the relations between well location and reservoir development, by comparing resistivity value and seismic coherence characteristics among depression, slope and broken ridge belt in limestone of the Yijianfang and Yingshan Formations. By means of logging data, imagine data and formation test data, we studied the relationship between dolomite degree and reservoir in dolomitic limestone of the Yingshan Formation and dolomite of the Penglaiba Formation. For the limestone formations, reservoirs were well-developed in broken ridge belt and poorly-developed in depression and slope. For the dolomitic limestones and dolomite formations, reservoir developments were related to dolomitization degree. |
