摘要:
水洗资料表明,在当前开发条件下,喇萨杏油田部分表外储层难以动用。为提高表外储层剩余油的挖潜程度,基于岩心水洗分析、压汞、测井资料等,以长垣Ⅰ类独立表外、Ⅱ类独立表外层为研究对象,研究在当前开发条件下表外储层的动用难易程度。确定当前开发条件的表外储层分类物性、含油性标准,并采用岩心刻度测井技术,分区块、油层组建立不同系列测井分类方法。通过表外单采试验区表明,单井产液强度随射孔厚度中易动用厚度比例的增大而增大,测井解释为难动用的表外层注入百分比较低,注水强度也较低,分类结果和生产动态实际较为吻合。
Abstract:
The washing data show that under the current development conditions some untabulated reservoirs in the Lasaxing oilfield were difficult to develop. In order to improve the recovery rate of residual oil in the untabulated reservoirs based on core washing analysis mercury pressure and log data class I and II independent untabulated reservoirs in Changyuan were taken as the research object to study the difficulty of untabulated reservoir utilization under the current development conditions. Based on the research results the physical and oil-bearing classification standards of the untabulated reservoir of the current development conditions were determined and the different series of log classification methods for different blocks and different oil layers were established by using the technology of “core calibration logging”. Based on the single well production data of the untabulated reservoir in test area the liquid production volume of single well increased with the thickness increase of reservoir which was easy to develop. When untabulated reservoir was interpreted as the reservoir which was difficult to develop the percentage of injection was lower the corresponding water injection intensity was also low. The classification results were in good agreement with the actual production dynamics.
