低渗油藏试井新技术研究及应用

针对低渗油藏特点,从压力监测技术状况分析入手,对采取何种方式缩短测压时间对油藏进行了规律性研究,采用早期资料解释与二流量测试技术相结合,对不同油藏采取不同的解释及测试方式,在利用先进的试井解释方法的同时针对不同的油藏在测试工艺上寻求突破,确定不同渗流条件的储层合理的测试工作制度,科学合理的测试时间既可以满足参数计算要求,同时又不因过长时间的关井而影响产量,有效缩短测试周期。较好地解决了动态监测占井时间长与原油生产之间的矛盾,从而间接增加生产时间,提高单井年产量。

Research and application of well testing new technology in low permeability reservoir

According to the characteristics of low permeability reservoirs,from pressure monitoring technology condition analysis,to take whatever to shorten the time we on the reservoir pressure measuring the regularity study,adopting early data interpretation and 2 flow test technology combining different reservoirs adopt different interpretation and testing methods, in the use of advanced logging interpretation method at the same time according to different reservoirs in testing techniques in the breakthrough,define different seepage condition of the reservoir reasonable testing work system,scientific and reasonable testing time for both can satisfy parameter calculation requirements,while again not for too long time shut-in to affect yield,effectively shorten test cycle.A good solution to the dynamic monitoring of crude oil production wells with long time,the conflict between causing an indirect increase production time and improve production well.
