| 摘 要： | 前河油田九佛堂组为一套水下扇沉积。通过对不同层位取心井粒度资料分析及对比,分析其差异的原因,确定各层位搬运方式及沉积作用形式,并运用霍姆斯水流强度图分析从湖盆边缘向湖盆内的水流强度变化。根据岩性组合及测井曲线特征,识别出扇根、扇中前缘及扇端3种微相。并认为沿水流及砂体发育方向为部署有利区带。

| Abstract: | The Jiufotang Formation in the Qianhe Oil Field, Ludong depression, Liaoning is built up of a succession of submarine fan deposits generated by the gravity flows and tractional currents during the deposition of the Jiufotang Formation and Shahai Formation. Three sedimentary microfacies have been distinguished, according to lithologic associations and well logs, including the proximal fan, mid-fan front and terminal fan, of which the mid-fan front sandstones turned out to be excellent reservoir rocks because of the discovery of the industrial oil run indicated by the L1 well in the study area. |
