Abstract

Abstract:

The efficient extraction and utilization of oil and natural gas are closely related to the security of China′s energy development.Continuously improving the efficiency of oil and gas extraction and resource utilization is an important development direction for China's oil and gas extraction.However，salt scaling is often accompanied by the exploitation of oil and gas fields，leading to the blockage of key equipment such as pipelines，drilling tools，and oil and gas wells and seriously reducing the efficiency of oil and gas exploitation.To conduct in-depth analyses of the principles behind salt scale formation in oil and gas fields and develop a series of anti-salting techniques is the direction to address the challenge.The research results on the composition and mechanism of salt crystallization in existing oil and gas fields were reviewed. The commonly used antisalt technologies were systematically analyzed.The types and principles of developed antisalt agents were summarized.The screening principles of antisalt agents，the challenges faced in their research，and the future development trends were summarized，providing theoretical support and practical guidance for the design and development of new antisalt agents in future oil and gas field system.

Key words: oil and gas field, salt scale, salt formation mechanism, crystallization inhibition, antisalt agents
