摘要
过套管电阻率测井是电法测井中一个新的领域,通过测量金属套管壁外岩石的单位电阻率(ρ)可以评价储集层的含水饱和度,进而寻找未动用油气。跟踪油藏流体饱和度的变化以及油藏流体界面的运移情况,对解决老井和部分套管井的重新评价,以及开发过程中的油藏监测具有非常重要的意义和广阔的应用前景。在阐述过套管电阻率测井仪器结构及工作原理的基础上,通过对实际测井资料进行综合分析,总结了过套管电阻率测井资料的优势所在,并针对中低渗透储层评价的技术需求进行了积极地探索。
Cased Hole Formation Resistivity（CHFR） Logging is a new field of the electrical logging. The watersaturation of reservoir can be evaluated by measuring unit resistivity of the rock in the outer metal casing and this method can be used to search for the unused hydrocarbon and track the changes of the fluid saturation and migralion situation in the reservoir fluid interface and solve re-evaluation of old wells and some casing wells, h has very important significance and broad application prospects in the reservoir monitoring of oilfiehl development process. Based on the expatiation of CHFR instrument structure and working principle, advantages of CHFR are summarized and also positively explored technique demands in the middle-low permeability reservoir assessment technology are summarized, by comprehensive analysis to actual logging data.
