摘要

辽河盆地欢喜岭油田欢北杜家台油藏具有低孔、低渗、非均质性强的特点，经20多年的开发，措施产量下降,层间矛盾日益突显。沉积微相特征分析表明，扇三角洲前缘亚相是研究区主要的沉积相类型;通过对水下分支河道、水下分支河道间(湾)、河口砂坝和前缘席状砂等沉积微相的岩性、电性和沉积构造特征进行分析，优选出3个有利目标区块,采用小网格模拟出研究区沉积微相模型，并在此基础上建立了储层物性参数模型。开发验证结果表明，相控条件下所建模型更接近地下地质实际，可为老区剩余油挖潜提供依据。

Abstract

The reservoir of Dujiatai in the north of Huanxiling Oilfield is of low porosity, low permeability and high heterogeneity. The characteristics of the reservoir and the microfacies in the study area was analyzed and researched. The characteristics of the microfacies, including underwater channel, underwater interfluve, debouch bar and sheet sand, were analyzed in the area. The microfacies model and the reservoir model of the study area were built up by using fine grid and lots of indicators in three target blocks. The results show that, under the control of the facies model, the reservoir model can show the underground facts better, and the model is fit for the work of developing the remaining oil.

Key words： Fan delta reservoir; Microfacies study; Reservoir modeling; Dujiatai in the north of Huanxiling.
