Downhole throttling technology is to adjust downhole pressure through installing the throttle valve in an appropriate position on the tube. The gas flowing through the throttle valve is heated up by the geotherm and the conditions of gas hydrate formation are changed, so as to effectively prevent gas hydrate formation, decrease transportation pipeline pressure, eliminate attemperator, and reduce the cost of gas production.

The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.
