Accumulation conditions and enrichment controlling factors of natural gas hydrate reservoirs

doi:10.3969/j.issn.1672-7703.2018.03.005

Abstract

Abstract: Natural gas hydrates are solid, ice-like clathrates formed with hydrocarbon gases (mainly methane) and water under appropriate temperature and pressure conditions. Different from conventional hydrocarbon reservoir systems, the key factors controlling gas hydrate accumulation mainly involve stable natural gas hydrates, water source, natural gas source, fluid migration and reservoir space conditions. The accumulation factors of natural gas hydrates determine that gas hydrate production from stable gas hydrate zones is neither continuous nor stochastic, and gas hydrates in different geological settings have different distributions and geological characteristics. Natural gas hydrate accumulation and enrichment controlling factors involve the following points:Controlled by temperature and pressure, natural gas hydrates are dynamically formed, accumulated and distributed in stable gas hydrate zones; natural gas hydrates are contained in loose sediments at relatively shallow layers after the Later Miocene, generally 0-500 m below seabed; natural gas hydrates are generally of low abundance, extensive distribution and local enrichment, and with concentrated "sweet spots" zones; natural gas hydrates have microbiological and thermal genetic characteristics, and their large-area accumulation depends on favorable fluid migration; natural gas hydrates occur in solid form, and their growth and occurrence are diverse, such as in structural, stratigraphic and complex reservoirs.

Key words: natural gas hydrate, accumulation conditions, geologic characteristics, dynamic accumulation, concentrated "sweet spots", zone
