渤南洼陷渤深6碳酸盐岩潜山储层描述
|
摘要
渤南洼陷渤深6碳酸盐岩潜山油藏埋藏深度大,储集空间复杂且油田开发投资巨大,正确的储层描述成为油藏有效开发的关键。为此总结出一套适合深层复杂潜山的储层描述方法,核心技术包括潜山识别与构造解释、成像和核磁共振测井资料的储层物性及含油性解释、测井参数约束的地震资料反演预测裂缝分布等。在储层描述及综合分析的基础上,所设计的14口新井全部钻遇油层,钻井成功率达到100%,且均为自喷生产,平均单井产油量为60t/d,取得了该区潜山油藏高效开发的良好效果。
Accurate reservoir description is the key of effective exploitation for the deep buried and complex reservoir space and large investment of oilfield development in carbonate reservoir of Boshen6 buried hill in Bonan Subsag. A set of reservoir description methods suitable for deep and complicated buried hill have been found. The key techniques involve buried hill identification and structure interpretation, interpretation of physical and oil bearing properties of the reservoir by imaging and FMI data and prediction of the fissure distribution by inversion of seismic data bounded with well log parameters. Based on reservoir description and comprehensive analysis, oil - bearing formations are drilled in the designed 16 new wells with 100% of the drilling success ratio. Good results of high-effective exploitation are achieved in the buried hill oil reservoir of this region with all flowing producing oil wells and 60t/d of oil production.
