中文摘要：
针对缝洞型碳酸盐岩非均质性强、异常压力成因机制复杂的特点,分别建立等效深度法、Eaton法及有效应力法的地层孔隙压力测井预测模型,对比分析各方法的适用性。分析表明,改进的有效应力法综合考虑了孔隙度、泥质含量和密度等因素,可避免单因素导致的精度低和误差大的问题,且无需建立正常压实趋势线,能够满足缝洞型碳酸盐岩地层孔隙压力的预测需求。
英文摘要：
Vuggy carbonate rock has strong heterogeneity and complex genetic mechanism of abnormal pressure. For these characteristics,this thesis established equivalent depth model,Eaton model and effective stress model to predict pore pressure based on logging data. The research indicated that the improved effective stress method,takes the effect of the porosity,clay content and density into overall consideration,which considers more factors in the conformation of abnormal pore pressure and avoided establish normal compaction trend line,so it is fit for the prediction of pore pressure in this area.
