Abstract: In view of the various problems existing in the current production profile testing for horizontal well staged fracturing, the development direction of horizontal well profile testing technology is further clarified by analyzing and comparing the technical principles and adaptability of such three testing technologies as the distributed optical fiber, the production logging and the tracer monitoring to identify advantages and disadvantages of these technologies and providing an outlook on the development trend of each technology. The research shows: The distributed optical fiber monitoring technology is stable and easy to install, but the storage capacity is large and cannot be interpreted quantitatively; the production logging technology has high precision, but it is not applicable in some cases; the tracer logging involves many types, each with its own advantages and disadvantages; In the future, the in-depth research on logging technology can be carried out from the aspects of technical equipment and data interpretation. This research can provide some technical reference for the field test selection, and also provide some new perspectives for the follow-up technical development.
