“…For the argillaceous‐silt NGH development, high sand control precision is required because of the small particle size of produced formation sand. The small flowing path on the sand control screen causes an extra pressure drop 59 .

The paper investigates the heat transfer in the exploitation of offshore argillaceous-silt natural gas hydrate reservoirs considering sand control. The temperature prediction model is established in this investigation. The coupled pressure-temperature model of the flowing fluid inside the wellbore is also presented. The sand control for argillaceous-silt natural gas hydrate reservoirs mainly brings two effects into the temperature and pressure profiles simulation, including the moderate sand control and the Joule-Thompson effect. The moderate sand control is reflected by the volume and particle size of produced sand into the wellbore in the mathematical derivation. The Joule-Thompson is considered in the model due to the small diameter of sand control screens. The experiment is designed to measure the pressure drop caused by various mesh diameters of sand control screens. Subsequently, the regression relationship between the pressure drop and the mesh diameter is concluded to calculate the temperature change at the sand control screen. The simulation of heat transfer helps to analyze secondary hydrate formation risk in the wellbore. The proposed model identifies the high-risk location of the secondary hydrate formation. The sand control effect and well geometry effect are discussed quantitatively. The strict sand control in the argillaceous-silt natural gas hydrate (NGH) sediment exploitation reduces the risk of secondary hydrate formation significantly; however, it also has a negative effect on natural gas production. To balance the sand control and the prevention of secondary hydrate formation risk, it is suggested to install the heating electrode in the high-risk location to ensure flow safety with acceptable sand control precision. The heat provided by heat electrodes is calculated by the model presented in this paper. The model can be used to determine the proper arrangement of heat electrodes. The paper also describes the secondary hydrate formation by adjusting the well geometry. The formation depth of the NGH reservoir and the sea interval should be considered in the risk analysis of

Natural gas hydrate (NGH) has the characteristics of low pollution and large reserves, which is considered as a very promising energy source. The extraction of NGH would cause the strength and stiffness reduced in hydrate-bearing sediment (HBS) reservoirs, which could lead to geological disasters. The mechanical properties of HBS have been studied by a large number of scholars, but it has not been sorted out and summarized for HBS under the influence of multiple factors. In this paper, the hydrate types, synthesis methods, and test conditions are summarized. The effects of hydrate saturation, loading rate, temperature, pore pressure, confining pressure, fine content, and clay content on mechanical properties and deformation behavior of HBS are outlined. The microstructure of the synthesis, decomposition, and shear processes of HBS specimens is also analyzed based on the CT triaxial shear test system, and the microscopic mechanism of HBS specimens in the shearing process is summarized. Finally, the shortcomings of current research on the mechanical properties of HBS are discussed, and provided corresponding suggestions to promote the development of the mechanical properties of HBS.
