Methods of well logging evaluation and identification for carbonate reservoirs with fracture and vug are researched in this paper by using conventional logs and imaging logs.
本文利用常规及成像测井资料,对碳酸盐巖缝洞型储层的识别与评价方法进行研究。
Parameters sensitive to facture and vug reservoirs are chosen. Principles of integrated characteristic parameters in reservoir identification are introduced.
首先提取了对缝洞型储层反映敏感的测井比值参数,介绍了用于储层识别的综合特征参数的原理;
The double logarithmic curve could be divided into four stages-wellbore storage effect reaction stage, fracture reaction stage, vug reaction stage, and boundary reaction stage.
第四段为边界反应阶段,由于忽略基质渗流,故可视为封闭边界,导数曲线上升。
Based on the geological data of Tahe Oilfield, the well test interpretation model of the reservoir with the fracture and vug which are connected with well-bore is established.
