摘　　要：针对压缩空气储能注采井地质特征、工程特征以及钻探过程中的技术难点,确定了录井技术评价方向,从3个方面开展了录井技术研究。依托XRD和XRF技术,经过饱和盐水实验,建立了石盐、石膏、芒硝的评价方法;依托综合录井工程参数,结合注采井在入腔卡层过程中的5个阶段,建立了工程异常状况预警标准;依托地质资料,结合工程要求,建立了压缩空气储能注采井卡层方法。经过现场施工7口井验证,工程异常预警18次,准确率为100%,中完卡准盐腔顶部准确率为100%,充分验证了上述评价方法的有效性,为后期压缩空气储能注采井钻探提供了可借鉴的方法和标准。Mud logging technology evaluation is determined in this paper from 3 aspects to solve geological and engineering characteristics and technical difficulties in drilling and exploration process of compressed air energy storage injection-production wells.The evaluation method for halite,gypsum and mirabilite has been established by saturated brine experiment based on XRD&XRF technology.Based on comprehensive mud logging engineering parameters,the forecasting standards for abnormal engineering situation have been built with the combination of 5 stages in determining horizons of entering cavity of injection-production wells.Relying on geological data and combining with engineering requirements,the horizon determination method of compressed air energy storage injection-production wells has been set up.There are 18 abnormal situation alarms in the verification of 7 wells on the site,the accuracy rate is 100%,and the accuracy rate of finding the top of the salt cavity is 100%after midway completion,which fully verifies the effectiveness of the above evaluation methods,and provides reference methods and standards for the later drilling of compressed air energy storage injection-production wells.
