白豹袁和庄油藏特征研究

Reservoir characteristics of Baibao yuanhezhuang

研究区域白豹袁和庄地理位置位于延安市吴起县东南白豹镇,构造上处于鄂尔多斯盆地陕北斜坡的西部。随着该油区开采程度不断增加,发现该油藏岩性变化大、油水关系复杂。本文通过对油藏构造特征及类型、沉积特征、油藏纵面及平面分布特征的重新认识,对该区块的油层措施改造、完善注采对应、注采井网调整以及下一步新建产能具有重要的指导作用。

The study area Baibao Yuanhezhuang is located in Baibao Town,southeast of Wuqi county town,yan’an city,in the western part of the northern slope of Ordos Basin.With the increasing exploitation of the oil area,it is found that the lithology of the reservoir changes greatly and the oil-water relationship is complex.In this paper,through the re-understanding of the reservoir structure characteristics and types,sedimentary characteristics,reservoir vertical and plane distribution characteristics,it has an important guiding role for the transformation of reservoir measures in the block,the improvement of injection-production correspondence,the adjustment of injection-production well pattern and the next new production capacity.
