摘要
G地区P油层砂岩储层普遍含钙,对储层电性、物性均产生较大影响,使得利用电阻率进行储层流体定性识别和定量评价变得困难。利用常规测井系统探讨了钙质含量定量计算模型的建模样本选取方法,并利用微球聚焦曲线和声波时差曲线建立了钙质含量计算模型,在进一步分析流体性质影响情况下,建立了电阻率的钙质校正方法,通过校正,提高了储层评价的解释精度。
The complex sandy bed in G District of P Reservoir was characterized by high calcareous content,which was difficult to qualitatively appraise the reservoir fluid.The calcareous content calculating model,including sample is established by using conventional logging system.Curves of microspherically focused log and interval transit time log are used to establish a model for calculating calcareous content.Under the condition of further analyzing the calcareous influence,its correcting method is determined.The method is used with high evaluating accuracy.
