Status and development suggestion of horizontal-well production profile testing technologies

As an important oil/gas well performance monitoring method, horizontal-well production profile testing technologies can deepen geological understandings, optimize development schemes and improve single-well production rate, so as to play a role in the cost reduction and efficiency improvement of oil and gas field development. At present, production profile testing of horizontal well is carried out mainly by means of production logging technology, distributed optical fiber monitoring technology and intelligent tracer monitoring technology. These three technologies are different in testing principle, testing process and data interpretation and they have different application conditions, advantages and disadvantages. These three technologies were reviewed from the the aspects of logging instrument’s status, optical fiber sensor’s type, intelligent tracer’s development, testing process and data interpretation method. In addition, the applicability, advantages and disadvantages of the related technologies were compared and analyzed, and the corresponding development suggestions were proposed. The status study and applicability analysis on the horizontal-well production profile testing technologies provides a reference for the selection of oil/gas well performance monitoring methods and promotes the development of horizontal-well production profile testing technologies.
