该项研究通过对已开发系统取心井29口,2 065 m岩心观察描述,对比319口井试油热采资料,分层对比1090口井,划分油层有效厚度565口井,系统解释330口井单井参数,结合分析化验数据12项5224块次、岩性、电性、含油性、以及投产资料进行综合研究,对储层重新评价,对“四性”关系进行深入研究,建立超稠油油层标准。完善了稠油松散岩石的孔隙度、含油饱和度、渗透率、泥质含量及储层岩性测井评价解释模型,编制并完善了超稠油储层参数测井解释模块,建立了有效储层参数评价标准,并进行了储层参数平面变化规律研究。该项目对超稠油油藏探明剩余资源量及经济合理地开发超稠油油藏提供依据。
Based on the observation of 29 cores and 2065 m cores of developed coring wells, this study compares the data of 319 wells with the oil and thermal recovery data, and stratifies the comparison of 1090 wells, divides the effective thickness of 565 wells and explains 330 Wells wells parameters, combined with the analysis of laboratory data of 12 5224 blocks, lithology, electrical properties, oil, and production data to conduct a comprehensive study of the reservoir re-evaluation of the “four” relationship in-depth study to establish Super heavy oil reservoir standards. The porosity, oil saturation, permeability, shale content and reservoir lithology logging evaluation and interpretation model of loose rock of heavy oil were perfected. Well logging interpretation module of ultra-heavy oil reservoir parameters was established and improved. Layer parameters evaluation criteria, and carried out a study of reservoir parameters plane changes. This project provides the basis for ascertaining the remaining resources of ultra-heavy oil reservoirs and developing ultra-heavy oil reservoirs economically and reasonably.
