摘要

The problems of frozen plugging and liquid loading in gas wells affect productions of oil and gas wells all the time. Based on hydrate properties and its generating conditions, a downhole choke bean and its releasing fishing tools have been developed successfully which have been granted as a state patent in 2001. By using wireline setting and fishing, this technique transfers multi-stage choke on the ground to downhole one-stage choke, improving the outlet temperature and liquid carrying capacity after the depres-surization of natural gas, simplifying the ground flowsheet. It has been a very practical patent techniques for prevent oil and gas wells from frozen plugging and liquid loading. It has been applied for 183 times at home and abroad and 0.21 billion yuan has been saved in total. Therefore, significant economic profits has been achieved.
