浊积岩油藏描述技术及其应用

Turbidite reservoir description technique and its application

由于浊积岩型油藏储层分布广、变化大、埋藏深、隐蔽性强,开发难度大,因此,油藏的前期描述工作就成为开发该类油藏的关键。通过运用区域地质综合分析、地震判识、精细油藏描述等技术,在史南地区共发现沙三中亚段大小浊积砂体75个,并对其中Ⅰ类砂体进行滚动勘探开发,取得了较好的效果,并形成了一套浊积岩型油藏描述及滚动勘探开发技术。

Turbidite reservoirs are broadly distributed, greatly various, deeply buried, more subtle, and difficult to recover, so that preliminary reservoir description is important. Through areal geology analysis, seismic discretion and precise reservoir description, 75 turbidite sands have been discovered in mid - sub member of s3 formation in Shinan area. Progressive exploration and development have been carried out for the Class I sands and resulted in good effect. A set of techniques for turbidite reservoir description and progressive exploration and development has been established.
