“…Крім того в роботі [9] приведені результати визначення відкольної міцності для сталей типу 12Х18Н10Т з оцінкою тиску в ударній хвилі і швидкості деформування, а також з вимірюванням товщини відколу методом зважування. Залежність від відкольної міцності від тиску ударної хвилі невизначена, оскільки має широке поле розсіювання.…”

Compound perforation fracturing technology is a space combination type ultra-deep perforating that can overcome some flaws conventional perforation has, such as shallow penetration and compaction damage. It can remove the compaction band and near wellbore pollution in rock matrix which results from conventional perforation. This paper introduces the theory of effect and influence factor of compound perforation fracturing technology and summarize the advantages for low permeability gas well on the basis of analyzing the mechanism of action about increase production of compound perforation. In order to evaluate the effects of application of this technology in in low permeability reservoir, 11 compound perforation wells and 12 conventional perforation wells were selected which have the similar physical property and the evaluation was conducted in two blocks. The results show that compound perforation can make the formation fracture pressure decrease in 3~5MPa and increase the permeability near the perforation channel. This technology has better effects than the conventional and decrease the cost effectively, improving production in low permeability oil and gas field.

“…Some of these models adopt restrictive assumptions to simplify the model formulation, but such assumptions also limit the applicability of these models to special classes of problems. So the higher requirement is put through for the concrete material model [8], [9] . The HJC model is used in this article to describe the character of the concrete [10] .The strength is the function about the pressure, strain rate and degree of damnification (as in Figure2), which is defined as:…”

In previous earthquakes, masonry structures, especially those masonry structures with prefabricated slab was damaged severely, and caused heavy casualty and property losses. In order to improve the seismic behavior of prefabricated slab, a new type of prefabricated slab with longitudinal and transverse joint steel bar was designed. By employing a numerical simulation procedure, LS-DYNY3D, models were established, and their seismic behaviors were analyzed .The results show that, the masonry structure of new type prefabricated slab with longitudinal and transverse joint steel bar is better than the structure with traditional prefabricated slab in structural integrity and stability. That is to say, its seismic behavior is better than the masonry structure with traditional prefabricated slab.
