摘　　要：随着国内外高温深井钻探的逐步增多,针对高温井电成像装备缺乏的市场现状,在传统电成像测量技术的基础上,使用厚膜集成电路技术与保温瓶绝热技术研制出了适用于200℃高温井的电成像测井仪器。在实验室对仪器电路模块进行了高温测试,200℃高温环境下的电路测量信号与常温相比变化很小,可以满足电成像测量需求。在现场某高温井进行了现场作业,测得全井段1 500 m的合格资料,图像清晰地显示了井壁的沉积构造等地质特征,对资料进行了地层岩性识别、沉积构造分析、沉积微相划分与古水流方向分析等地质评价,取得了良好的应用效果。为后续地质分析研究提供了依据,填补了175℃以上超高温井无电成像测井装备的技术空白,对国内外超高温井的油气勘探开发具有重要意义。With the gradual increase of high temperature deep well drilling at home and abroad,aiming at the lack of high temperature electrical imaging tool in market,and on the basis of the traditional electrical imaging tool technology,an electrical imaging tool for 200℃high temperature well has been developed by the thick film integrated circuit technology and thermos insulation technology.In the laboratory,the circuit module of the instrument has been tested at high temperature.The circuit measurement signal in high temperature environment of 200℃high temperature has little change compared with the room temperature,and it can meet the needs of electrical imaging measurement.On-site operation was performed on a high temperature well,and the qualified data of about 1 500 m well section was measured,and the image clearly showed the geological characteristics of the well wall such as the sedimentary structure,and stratum lithology identification,sedimentary structure analysis,sedimentary microfacies division and paleocurrent direction analysis and other geological evaluations on the information were carried out,which has achieved good application results and provides the basis for the follow-up geological analysis.The technical gaps of no electrical imaging logging tool for the ultrahigh temperature well above 175℃are filled,which has great significance for oil and gas exploration and development of ultra-high temperature wells at home and abroad.
