Development status and prospect of CBM well production control technologies

  • In this paper, the development course of the production control technologies of coalbed methane (CBM) well was reviewed. Then, based on the current automatic production technologies, the development directions of smart production technologies in the future were prospected. It is shown that automatic production equipment is advantageous with high control accuracy, convenient maintenance and low composite operation cost and it has been extensively popularized in the field of CBM development, but its production control system and equipment parameters are all manually set according to operators’ experience, so they are of higher uncertainty. One of the important research directions in the field of CBM development in the future is combining the machine learning algorithm with the automatic production technologies of CBM well for the development of smart production decision making system to provide accurate productivity prediction and production system setting for the smart production of CBM wells.
