摘要
实施保护油气层技术是当今石油勘探开发过程中的一项关键技术,成功的前提是要获得对地层损害客观、真实和准确的评价结果。模拟井下地层温度120℃、围压50MPa和钻井完井动静态滤失条件的高温高压多点岩心电阻率渗透率测量系统,沿着长达96cm的柱状岩心轴向上分布有16个测电测压点,通过多点岩心电阻率的渗透率的同时测量,不仅可以直接精确地确定工作液侵入深度和损害程度,并获得工作液动静态滤失数据,从而优选工作液;而且,通过井下真实模拟的转换,并结合现场生产资料,可直接用于确定钻井完井损害、测井解释以及水驱效率和三采效果评价等,具有极为广泛的应用范围和极其广阔的应用前景。
It is a key technique to protect reservoir in oil exploration and development nowaday. The objective,real and accurate evaluations on formation damage are requlred before applying the technique. The multipoint core resistivity and permeahility measurement system with sixteen ports along 96 centimeter long core axial direction, which can simulate formation temperature 120℃,confining pressure 50 MPa and dynamic and static conditions of borehoie fluids,can simultaneously test cores' resistivities and permeabilities. Not Only are the invasion depth and the damage degree as well as the filtration data of fluid obtained in order to select the best borehole fluld,but aiso the evaluations and studies on formation damage during well drilling and completion,well logging anaiysis,water flooding and enhanced oil recovery can be obtained after the experiment results in exchange for operation conditions. Therefore,the system has various application fields and a bright future.
