Coal permeability measurements are normally conducted under the assumption that gas pressure in matrix is equalized with fracture and sorption-induced swelling/shrinking strain uniformly distributed within coal. However, validity of this has long been questioned differential between bulk considered as primary reason for inconsistency experimental data poroelasticity solutions. Although efforts have made to incorporate impact into coal models, fundamental nature those split remains...
In complex mountainous areas where earthquakes are frequent, landslide hazards pose a significant threat to human life and property due their high degree of concealment, development mechanism, abrupt nature. view the problems existing hazard susceptibility evaluation model, such as poor effectiveness inaccuracy data need for experts participate in calculation large number factor weight classification statistics. this paper, combined SBAS-InSAR (Small Baseline Subsets-Interferometric...
As urban construction has been leaping forward recently, large-scale land subsidence caused in Kunming due to the special hydrogeological conditions of city; scope stretched out, and rate rising year by year. a consequence, Kunming’s sustainable development seriously hindered. The PS-InSAR (Persistent Scatterer Interferometric Synthetic Aperture Radar) SBAS-InSAR (Small Baseline Subsets technologies were adopted process descending Sentinel-1A data stacks from July 2018 November 2020 monitor...
In the production of high-definition maps, it is necessary to achieve three-dimensional instantiation road furniture that difficult depict on traditional maps. The development mobile laser measurement technology provides a new means for acquiring data. To address issue traffic marking extraction accuracy in practical production, which affected by degradation, occlusion, and non-standard variations, this paper proposes 3D reconstruction method based energy functions template matching, using...
This paper proposes a new method for the automatic generation of digital terrain model (DTM) from airborne laser scanning technique. First, generate regular grids, and then filter points on each grid. Finally, change size grid these grids repeatedly. The data measured by LiteMapper-5600 in city is used to evaluate method. results show that this can remove most non-ground effectively DTM with high-accuracy urban areas.
Abstract For sandstone reservoirs with extra-low permeability, CO 2 injection is regarded as a valid method to enhance oil recovery. When implemented in such reservoirs, the physical properties of formation could be altered owing interactions between , water, and rock. In this study, influence –brine–rock on tight cores was analyzed by comparing obtained T spectrum before after injection. The results revealed that significantly different from original spectrum. changed pore size distribution...
Due to the extensive development of fractures and serious heterogeneity in fractured reservoirs, it is difficult for traditional numerical simulation method invert its geology, which greatly limits efficiency accuracy cannot realize real-time optimization production scheme. The connectivity model can only consider two characteristic parameters conductivity volume, does not involve complex rigorous geological modeling. It quickly accurately reflect state real reservoir, reducing time,...
Kunming, as an important urban interchange point along the "One Belt And One Road", is in peak period of subway construction. However, due to ground characteristics, process construction and operation, it easy cause surface subsidence, which threatens people's lives property safety. Therefore, great practical significance master deformation lines timely accurately. Taking Kunming network example, this paper, 69 Sentinel-1A SAR images city from July 20, 2018, November 18,202,0 were processed...
