Abstract

The exploitation potential of natural gas hydrate is huge. Many countries in the world have carried out research and exploration on the key technologies of natural gas hydrate exploitation. At present, depressurization production of natural gas hydrate is mainly adopted. Due to the limited area of offshore platforms and the limited artificial lift options, gas lift technology, as a mature artificial lift method, has been widely applied in onshore and offshore oil and gas fields, but has not been applied in hydrate reservoir. In this paper, the gas lift technology is proposed as the main means of hydrate depressurization production, and the optimization design of gas lift technology parameters of hydrate reservoir is carried out on the basis of the optimization of multiphase pipe flow calculation model. The calculation results show that the gas lift technology can significantly reduce the bottom hole pressure of the wellbore and can be effectively used for depressurization and drainage of the hydrate reservoir. With the increase of the depth of the gas lift string, the gas injection required to achieve the same bottom hole flow pressure will decrease continuously. In the initial stage of the test production of the hydrate reservoir, attention should be paid to optimizing the depressurization rate to avoid the phenomenon of freezing block near the well of the hydrate reservoir and the secondary generation of the hydrate in the wellbore.
