摘要
揭示了葵花岛构造区浅层气规模小、埋藏浅、分布散、压力低、储层松散等分布特点,根据沉积环境和地质特征,推测浅层气为生物甲烷气,但并不完全排除是热生甲烷次生气藏的可能性,探讨了浅层气潜在的工程危害并提出相应防治措施,为今后海洋工程建设提供科学依据。
It is shown from the geologic study results that the distribution of shallow gas in the Kuihuadao structure area of Liaodong Bay are characterized by small scale, shallow burial, scattered distribution, low pressure and loose reservoir. It is deduced from the sedimentary environment and geologic characteristics that the shallow gas is biologic methan gas, and can also be secondary thermal methan gas. In this paper, the potential hazard of shallow gas to the engineering is discussed, and the associated prevention and control measures are also proposed, which provides scientific basis for the future marine engineering construction.
