查询词典 fractural

Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.

In fractural area, because the elasticity is heterogeneity, seismic wave absorbed and scattering, the seismic record is more complex. Thus, the Hurst exponent in fractural area is less than in non-fractural one.

在裂缝发育区段，由于地层介质弹性的非均质性及地震波的散射、吸收等使得地震反射序列变得更为复杂，这样，裂缝发育区地震信号的赫斯特指数小于非裂缝发育区。

The studies also show that the increased supporting force can reduce the radius of the fractural zone in surrounding rock derectly, but the main effect of the increased supporting force is to improve the compressive stress on rock in elastoplastic region, and to increase the rock strength of whole fractural zone so as to reduce the scope of fractural zone.

而当围攻岩中出现了塑性区和破裂之后，支护力的作用才开始显现。提高支护力可直接减小围岩破裂区范围，但提高支护力的主要作用是提高弹塑性区围岩压应力，达到提高破裂岩体宏观强度的目的，从而减小塑性区和破裂区的范围。

If the condylar fracture is treated inappropriate, it may cause some complications, eg: limitation of mouth opening, pain in TMJs, occlusion disorder, arthrocleisis and so on. The fractural condylar can't rebuild well without treatment. For any kind of condylar fracture, treatment should strive for anatomic replacement and avoid removing the fractural residual.

研究结论：髁状突骨折如治疗不当，容易出现一些后遗症或并发症，如张口受限、关节区疼痛、咬合错乱以及关节强直等；成人髁状突骨折如不作处理，并不能自行改建形成新的功能完好的关节；所有类型的髁状突骨折，治疗时都应争取达到解剖复位，不应轻易摘除骨折残端。

Because of increase of the oil-gas production of fractural reservoir, fractural reservoir is more and more important in the petroleum industry in China.

在我国，随着裂缝性储层油气产量的逐渐增加，裂缝性储层在我国的石油工业中占有越来越重要的地位。

In addition, this paper studied using the stochastic fractural theory to simulte the form of fracture, and thought that it is correct to describe fracture by the fractural characteristics of fracture grid.
