摘　　要：雅-大-轮凝析气藏已进入开发中后期,随着越来越多的气井因高含水停喷,需要利用测井资料寻找剩余油,指导停喷气井补孔转层、堵水等措施,恢复停躺井产能,提高采收率。对比各种测井技术的适应性,优选出适合砂岩凝析气藏的测试技术,并通过改进各俘获截面的取值方法,提高剩余油测井解释结果的符合率。对9口井进行二次解释,发现5口井符合生产情况;指导其余4口井措施挖潜,成功率100%,增油2.4×10^(4) t,增气1.4×10^(8) m^(3),有效提高了开发后期措施挖潜成功率。Ya-da-lun condensate gas reservoir has entered the middle and later stage of development.As more and more gas wells stop injection due to high water cut,it is necessary to use logging data to find remaining oil,guide the measures such as filling hole and transferring layer and plugging water against the stopped injection well,restore the production capacity of the shutdown or failed wells and improve the recovery rate.Through optimizing the testing technology for sandstone condensate gas reservoir based on comparing the adaptability of various logging technology,and improving the accessor methods of capture cross sections,the coincidence rate of log interpretation results of residual oil was improved.For the secondary interpretation of the 9 wells,it is found that 5 wells are in line with the production situation.Tapping measures guided by above interpretation were taken on 4 wells and the success rate is 100%,increasing 24000 tons of oil and 140 million m^(3) of gas,which effectively improves the success rate of tapping measures in the later stage of development.
