Abstract:

To develop the high sulfurous gas fields safely and efficiently, the features and difficulties of the high sulfurous gas fields different from the general gas fields should be given. Then pertinent countermeasures were put forward to solve the questions and guide high sulfurous gas fields development. According to analysis on many fields materials, the high sulfurous gas fields development had four dissimilar unique features and difficulties: serious sour corrosion, serious sulfur deposition, easy hydrate formation and rigorous desulfuration. Based on the difficulty of high sulfurous gas fields development, pertinent countermeasures to guide high sulfurous gas fields development are put forward, enhancing the prevention and curing study of hydrogen sulfide corrosion, sulfur deposition, hydrate, and desulfidate techniques.

Key words: the high sulfurous gas field, development, key question, countermeasure
