The combination of the dipping effect and hydromechanical (H-M) coupling can easily lead to water inrush disasters in water-rich roadways with different dip angles coal mines. Therefore, H-M tests bedded sandstones under identical osmotic pressure various confining pressures were conducted. Then, evolution curves stress-strain, permeability damage, macro- mesoscopic failure characteristics obtained. Subsequently, mechanical behaviour was characterized, finally mechanism revealed. results...
Abstract A Gemini zwitterionic viscoelastic surfactant named self diverting acid ‐ gemini sulfonated (SDA‐GS), which has double quaternary ammonium groups, sulfonate and two hydrophobic tails, was synthesized from oleylamidopropyl dimethylamine, 1,3‐propanesultone, 2, 2‐bis(bromomethyl)propane‐1, 3‐diol. The viscosity of an SDA‐GS aqueous solution varies with calcium chloride concentrations. With a decrease in the HCl concentration, prepared increases to maximum value, followed by decrease,...
Summary The Keshen Reservoir is a naturally fractured, deep, tight sandstone gas reservoir under high tectonic stress. Because the matrix very tight, natural-fracture system main pathway for production. Meanwhile, stimulation still required most production wells to provide rates that sufficiently compensate cost of drilling and completing access this deep reservoir. Large depletion (and related stress change) was expected during course field. dynamic response risks, such as reduction...
Abstract The Keshen reservoir is a naturally fractured, deep, tight gas sandstone under high-tectonic stress. Stimulation critical to the successful development of field. However, due heterogeneity natural fracture system in reservoir, there large variation productivity from production wells, which mandates different types stimulation operations simple acidizing massive hydraulic fracturing. Hence, improve efficiency and overall performance development, reliably evaluating wells optimizing...
Abstract Keshen Gas Field is part of Kuqa Foreland thrust belt, located in Southern foothill Tianshan Mountain, northern margin the Tarim basin, West China. The main pay zone, Cretaceous Bashijiqike (K1bs), has extreme reservoir conditions ultra-deep (6500-8000 m), high temperature (170-190°C), pressure (110-120 MPa)(HTHP). Thick salt and gypsum layers with dip angle above zone also increase safety concerns during drilling completion. Because its low porosity (2-7%), matrix permeability...
Abstract It is beneficial to understand deeply the permeability properties of coal and rock for stability control mining engineering, underground oil gas nuclear waste storage so on. Therefore, new insights bedded are summarized proposed. (1) "Five guarantees" coring technology worth vigorous promotion application. (2) The internal spatial fabric has significant effect on mechanical behavior evolution law (bedded) rock, but not dominant. (3) permeability‐energy models should be constructed...
Owing to the problems of guar gum fracturing fluid and conventional slickwater systems in hydraulic tight oil reservoirs, such as bad fracture network capacity, high damage, low sand-carrying performance, researchers are actively looking for new alternative fluids. This study takes four commonly used additives gas reservoirs western China, including polyacrylamide friction reducer EM30S, bioglue, thickener CHS-1, high-viscosity HVFR-1. By testing water solubility, rheological properties,...
The coal seam floor layout bottom drainage roadway is one of the effective means gas outburst elimination in working face. However, roof surrounding rock will undergo multiple disturbances such as excavation, drilling excavation and face mining, which easily lead to large deformation roadway, greatly affect safety stability mine. In this process, fracture borehole wall extraction expands, it subjected severe dynamic pressure during mining. At same time, redistribution stress brings secondary...
This article presents an effective method for improving the structure and performance of coal rock masses, thereby facilitating coalbed methane extraction—the grouting solidification technique. A systematic review is conducted on materials, process methods, evaluation techniques, other related aspects. In conclusion, it emphasized that technique requires further refinement in its system, continued significance dynamically evolving energy industry underscored. crucial ensuring efficient...
Abstract Gas reservoir K in Tarim oil field which is an abnormal pressure fractured tight sand may generate complex fracture due to the high rock brittleness. Microseismic monitoring technology a effective methods of evaluating network fracturing, but it had been limited by economic cost and service conditions. With extensive application SRV, necessary develop fast way evaluate complexity hydrofracture. The types morphology were evaluated analysis on drawdown after pumping, evaluation was...
Abstract In this paper, it’s studied that the characteristics and causes of adiabatic shear band produced by expansion deformation barrel muzzle during firing shells. The results show failure property launching process belongs to plastic distortion failure, in is caused abnormal contact collision between its internal components. It easy promote generation band, when material strength (hardness) high, but local strain large.
Abstract With the further development of Daqing Oilfield, proportion casing damaged wells is increasing day by day, because damage location mostly located in upper part reservoir, conventional technology can not carry out targeted fracturing construction,the low-yield and low-efficiency which limits efficient oil field. In order to satisfy needs subdivision large-scale construction with damage, this paper studied design principles, determined optimal theory different types wells, make...
