Natural gas hydrate (NGH) is widely distributed worldwide with great reserves and generally accepted as a promising alternative energy source. However, sustainable, efficient, safe NGH development has been proven to be restricted by series of geomechanical problems, among which sand production become prominent attention-catching. This review systematically summarizes the up-to-date literatures reports our latest work improve fundamental understandings issues in development. It noted that...
Mechanical properties of hydrate-bearing strata are crucial to evaluate hydrate production related geohazards. However, the mechanical parameters reservoirs in Shenhu area South China Sea have been rarely reported. In this paper, sediments from top taken analyze triaxial shearing behaviors clayey-silty containing tetrahydrofuran (THF) hydrates. The results indicate that stress–strain curves THF show strain-hardening failure characteristics under a relatively low mass fraction (≤16.7%)....
Mechanical properties of hydrate-bearing sediments (HBS) are crucial for evaluating drilling- and production-induced geo-hazards. However, investigations on mechanical behaviors clayey-silt samples containing hydrate insufficient due to low efficiency in preparing reconstituted samples. Herein, we carried out a series triaxial shear tests analyze the deformation tetrahydrofuran (THF) hydrate. The were taken from Shenhu Area, northern South China Sea. failure mechanisms during shearing...
Natural gas hydrate is an alternative potential energy source that contributes to depressurizing the pressure of supply and environmental pollution in future. Field production has a close association with geological risks. In this regard, accurate estimation strength deformation properties crucial risk prevention control during development. However, geomechanical hydratebearing sediments their applications remain unclear. Herein, work provides comprehensive summary studies on mechanical...
Deep shale has obvious bedding structure, and its complex anisotropic mechanical characteristics bring challenges to the development of gas resources. In order explore effect on properties failure modes shale. This paper takes Longmaxi Formation in Changning, Sichuan Province as research object, uniaxial compression tests were conducted with different angles, acoustic emission (AE) signals monitored during loading process. The under analyzed, a further comprehensive evaluation brittleness...
Commercial exploitation of marine natural gas hydrate (NGH) is crucial for energy decarbonization. However, production would weaken reservoir mechanical properties and trigger geohazards. Experimental instruments are the basis to obtain responses hydrate-bearing sediments (HBS). Considering deformation processes from elastic residual during exploitation, this study comprehensively reviewed feasibility research progress bender element, resonance column, atomic force microscope, triaxial...
The experimental testing and analysis of strength deformation characteristics hydrate reservoirs is an integral part natural gas exploitation. However, studies so far have failed to deeply explore samples from the South China Sea. Especially, there a lack simple applicable method estimate their mechanical behaviors. Thus, based on test data, improved Duncan-Chang model established in this paper characterize reconstituted with various saturation stress states area. This can accurately...
Aiming at the problem of restart-up for a heavy oil–water ring transportation pipeline due to instability and damage water ring, based on self-developed design small indoor loop simulation experimental device taking four kinds ordinary oil in Lvda oilfield as research object, change trend pressure drop with time is experimentally studied when restarted-up after shutdown constant flow. On basis regression analysis orthogonal data factors (oil holdup, viscosity, standstill period, cleaning...
Natural gas hydrate (NGH) exploitation is severely restricted by geotechnical problems. Deformation behaviors of the hydrate-bearing strata (HBS) control occurrence and evolution problems during extracting natural from HBS.
