THMC Fully Coupled Model of Natural Gas Hydrate under Damage Effect and Parameter Sensitivity Analysis

چکیده
In order to study the influence of damage on gas production natural hydrate, a multi-physical field theoretical model considering effect and coupling thermal-hydraulic-mechanical-chemical (THMC) was established by analysis numerical simulation. The THMC establishes relationship between elastic modulus hydrate sediment saturation during whole process decomposition. THC (thermal-hydraulic-chemical) fully coupled models not or were compared analyzed, reliability verified. On this basis, deformation, permeability sediments under different initial saturations depressurization amplitudes, as well rate cumulative production, are analyzed. results showed that higher inhibited development damage, maintained stable increased production. Larger promoted but it easy cause stability problems.

این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
15 صفحه اولSensitivity Analysis of Parameters Governing the Recovery of Methane from Natural Gas Hydrate Reservoirs
Naturally occurring gas hydrates are regarded as an important future source of energy and considerable efforts are currently being invested to develop methods for an economically viable recovery of this resource. The recovery of natural gas from gas hydrate deposits has been studied by a number of researchers. Depressurization of the reservoir is seen as a favorable method because of its relati...

The purpose of this paper is to analysis the viscoelastic models under dynamic loading. A five-parameter model is chosen for study exhibits elastic, viscous, and retarded elastic response to shearing stress. The viscoelastic specimen is chosen which closely approximates the actual behavior of a polymer. The module of elasticity and viscosity coefficients are assumed to be space dependent i.e. f...
متن کاملInvestigation of the Hydrate Formation Equilibrium Conditions of Natural Gas
One of the main problems in oil recovery via the gas injection is the formation of hydrates in thelines. In order to prevent the formation of hydrate in these lines, which leads to the blockage andsometimes explosion, at first, the equilibrium formation conditions must be determined and then toprevent its formation by changing the thermodynamic conditions or by adding the inhibitors. In thisres...
متن کاملMeasurement of Mass Transfer Coefficients of Natural Gas Mixture during Gas Hydrate Formation
In this study, mass transfer coefficients (MTC’s) of natural gas components during hydrate formation are reported. This work is based on the assumption that the transport of gas molecules from gas phase to aqueous phase is dominant among other resistances. Several experiments were conducted on a mixture of natural gas at different pressures and temperatures and the consumed gas was monitored an...
