Williams, Texaco, Inc., EPTD ABS7RACT A system has been developed and field tested that can detect NORM contaminated tubing 8s it Is pulled from a welt. E8r)

46、y, automatic identification of contaminated tubing can reduce the manpower required to manu8lly survey ail tubing for contamination. Early detection wit also allow field personnel to separate the contaminated tubing 8nd handle it as needed to prevent the spread of contamination. The system is compos

47、ed of a sodium iodide detector and an 818ming rate meter that can be mounted remotely. The alarm level is adjustable so it can be set to the desired level for different tube sizes, installation geometries, and background levels. INTRODUCTION Oil well tubing contaminated with NORM (Naturally Occurrin

48、g Radioactive Material) is found in many producing fields. To reduce the manpower requirements needed to identify contaminated tubing, we have developed and tested a system to identify contaminated tubing as it is pulled from a well. To reduce the cost of development and reduce the final cost to use

49、rs, we tested components of several commerciaf instruments. We laboratory tested several systems and selected two of them for a field test. One of the systems selected for a field test was mounted in an explosion proof box such as may be required in hazardous locations. Field tests have been held in west Texas and near offshore Louisiana. The field tested systems consisted of a 3x3 inch sodium iodide crystal detector and an alarming ratemeter. The systems were able to detect the contaminated tubing
