利用地震信息定量预测烃源岩TOC质量分数
Total organic carbon quantitative prediction using seismic information
摘要
Abstract
Considering that source rock evaluation is an important step of the whole process of oil and gas exploration in low exploration areas (deep water, deep layer), where the mass fraction of total organic carbon (TOC) of source rocks determines the resource potential and oil and gas reserves, based on the combination of seismic data and a few of drilling data, the mass fraction of TOC could be quantitatively predicted by seismic velocity inversion. The mudstone resistivity prediction model was established by velocity based on the FAUST equation-transformation. Furthermore, less well constrained seismic prediction model of mass fraction of TOC was built in combination with ΔlgR method. The mass fraction of TOC of C Sag of Y1 Member in the north of South China Sea was predicted by using this model. The results show that the mass fraction of TOC of the delta and coastal plain facies on the edge of the Sag is higher than that of shore-neritic facies in the sag center. The results are consistent with those of sedimentary facies, which verifies the reliability of this method.关键词
