FIELD APPLICATION OF SYSTEM OF TEMPERATURE MEASURING WITH OPTIC FIBER AND PRESSURE MEASURING WITH CAPILLARY TUBING

The technique of temperature measuring with optic fiber and pressure measuring with capillary tubing is a comparatively advanced technique in field test domain at present.The technique can realize the on-line detection and location of information such as temperature and pressure at any complex environment.This paper expatiates on the principle,composition and installation method of the system of temperature measuring with optic fiber and pressure measuring with capillary tubing;introduces the good effect achieved by Liaohe Oilfield when it used the system to conduct bottom hole monitoring in producers at steam auxiliary gravity drainage test center;and evaluates the advantage of the system.The system eliminates the "intrusion" possessed by the conventional method,make it possible for the real time detection of the well completion structure,which can be detected only at high cost before or even can not be detected.Thus,the system can help to obtain the data that can not be acquired by means of conventional monitoring method.
