The existing formation testing and fluid drainage operation methods are found with problems such as the long operation duration，complex operations，and likely damage to equipment，which seriously restrict the improvement of oil and gas field development efficiency and the reduction of development costs. Given these，this paper conducts a summary and analysis of the current state of technology regarding non-metallic composite coiled tubing materials and their associated running and pulling equipment used in the oil and gas field development sector. The technical parameters and field operation cases of different types of tubing and equipment are listed. Comparative analysis shows that in terms of tubing materials，the non-metallic composite coiled tubing available in China still cannot meet the operation requirements for wells with depths over 2 000 m，due to factors such as material strength and temperature resistance. It is necessary to further optimize material performance and develop and apply composite coiled tubing materials with higher strength and temperature resistance；in terms of equipment selection，skid-mounted operation equipment，combined tubing operation equipment，composite coiled tubing operation vehicles，etc.，can all meet the basic needs of current on-site operations of non-metallic composite coiled tubing in China. Comprehensive comparison of various operating equipment in terms of equipment costs，technical parameters，and operation efficiency suggests the combined use of non-metallic composite coiled tubing and conventional lightweight workover rigs is the most suitable application configuration for the current formation testing and fluid drainage operation using non-metallic composite coiled tubing.
