【摘要】 以GSM地区沙一段储层为例,提出了一套陆相碎屑岩储层的预测方法:在地质、测井研究的基础上,建立储层的地质概念模型。用反射强度、地层倾角变化、波形分类等方法研究地震相,在相分析的基础上重建储层的沉积演化过程,引入随机建模技术反演物性参数,查明有利物性区,并结合断裂分析对含油气性进行评价。这套方法技术在该区的应用中成效显著,所提供的钻探目标均获工业性产能。更多还原

【Abstract】 In the paper, taking Shalmember reservoir of GSM structure as an example, we present a set of prediction methods of clastic facies reservoirs: to build geologic model of the reservoirs based on geologic and well logging data, then reconstruct depositional evolution process in light of seismic facies analysis using the methods such as reflection strength, strata dip variation, waveform classification etc. and adopt random modeling technique to invert petrophysical parameters and determine favorable petrophysical zones, evaluate reservoir condition in combination with fracture system analysis. The satisfaction results have been achieved with commercial productions being encountered in the all provided drilling objectives in GSM region with the set of techniques.更多还原
