高温高压长工作时间系列测井仪的研制

Development of a series of logging tool long-time working under high temperature and high pressure condition

文章介绍了可挂接ECLIPS5700地面系统的高温高压长工作时间系列测井仪器的设计思想、原理、关键技术、温度压力测试方法和现场应用。随着油气田勘探、开发力度的加大,研制耐温204℃、耐压160MPa的长工作时间系列测井仪器以满足超深的水平井、大斜度井等复杂井况下测井的特殊要求具有非常现实的意义。实际应用表明该系列仪器具有高温高压下工作时间长、可靠性高、硬件结构简单、智能化程度高、易维修等特点。

This paper introduces the design idea,principle,key technology,temperature and pressure’testing method and field application of the series of logging tool working under high temperature and high pressure environment in the long time,which can be run in combination with the ECLIPS5700 surface system.With the further exploration and development of oil and gas field,development series of logging instruments can work under high temperature of 204 Celsius degree,high pressure of 160 MPa in the long time to satisfy logging under complex well conditions such as the ultra deep horizontal wells and high-inclination wells is very realistic significant.The application in fields indicates that the instruments can successfully work under high temperature and high pressure in the long time,It is characterized by high reliability,simple hardware structure,high intelligent degree,easy repair etc.
