摘　　要：TS区块的各油田基本都已经处于开发中后期,水淹严重,剩余油分布不清。为此引入了过套管电阻率测井技术,根据测量解释结果制定了具体的修井作业措施,从而指导生产。通过对比纯水层和泥岩层的电阻率得到K因子,数值基本保持在0.10~0.14范围内,一致性很好。为验证过套管电阻率测井的可行性和可靠性,新井中进行过套管电阻率测井,测量结果显示与裸眼井数据吻合较好。讨论测点质量控制标准和原则,数据解释之前应对异常点进行剔除,以提高解释准确性。过套管电阻率测井仪器已经在TS区块完成17口老井的测量,根据综合解释结果进行了相应的修井作业,增油控水效果显著,过套管电阻率仪器在该区块有较好适用性。Almost all the oilfields in Block TS have entered their mid-late stage of development,and water breakthrough is serious and the distribution of remaining oil is unclear.To improve the production,the cased-hole resistivity logging technique was introduced to help develop specific production stimulation plans based on logging interpretation.In this paper,the K factor obtained by comparing the resistivity of the pure water layer and the mudstone layer is basically within the range of 0.10—0.14,and it is very consistent;then resistivity logging data are collected in new cased wells,and they are well coincided with the resistivity data collected in open-hole wells;and finally the QC standards and principles of measuring points are discussed,and outliers should be eliminated before logging data interpretation.The cased-hole resistivity logging tool has been applied in 17 old wells in Block TS.Stimulation plans have been updated according to the logging interpretation.Stimulation result statistics show that production increase and water control is significant,indicating the cased-hole resistivity logging tool is very adaptable in Block TS.
