Formation mechanism and effective clearup of gas hydrate

During completion of oil and gas fields in deep water, the gas hydrate generated inside the tube column may block the channel, influencing the normal operation severely. Through the study on the formation mechanism and prevention of gas hydrates in this paper, solutions to the blocking of gas hydrate during completion are analyzed. Examples are given to illustrate the difficulties in field operation and the specific treatment schemes. This provides valuable theories and experience for deep water completion in near future and may be applied further.
