Abstract
The factors which bring the engineering geological disaster mainly consist of the shallow natural gas, natural gas hydrate, and shallow water flow. In this paper, we predict the 2D seismic profile of LW21-1-1 well by the gas chimney volume forecast technique, and the conclusions show that there are not obvious gas chimney characteristics in the location of LW21-1-1 while the possibility that the drill falls across the shallow natural gas and natural gas hydrate is very low.
