赛汉塔拉凹陷碳酸盐含量计算及其应用

Calculation and application of carbonate content in Saihantala Sag

赛汉塔拉凹陷储层为典型的低孔低渗储层.根据该区块地质特征,在分析其岩心实验资料、地质资料、测井资料及其响应特征的基础上,进一步研究利用测井曲线计算碳酸盐含量(体积分数)的有效方法,进而建立了基于碳酸盐含量的孔隙度、渗透率计算模型,为提高测井解释符合率奠定了良好的基础.

The Saihantala Sag in Huabei Oil Field is a typical reservoir of low porosity and low permeability.In this paper we analyze the block geological features,core test data,geological data,logging data and its response characteristics,study the effective methods for calculation of carbonate content using the well logs,and then establish the physical parameters calculation model based on carbonate content.It provides a basis for improving well log interpretation coincidence rate.
