  fractures
The tough fractures on the surface of the PU/PVC composite sample following impact are quite obvious.
      
Stress centralization will, in turn, cause a lot of fractures and faults to develop, and ultimately, result in a gas chimney, which is a seismic smear zone beneath or above the reef flat.
      
A system of two nonlinear equations in partial derivatives, of the hyperbolic type, is obtained for the concentration of one of the liquids in fractures and blocks.
      
The latter problem may be formulated, for example, so as not to permit closure of the fractures in the bottom zone.
      
The equations of horizontal displacement of miscible fluids from thin fractured porous formations are derived with allowance for all three mechanisms of mass transfer between the blocks and the fractures.

Method of numerical analog is discussed.A set of equations is worked out co- nsidering the thickness ,heterogeneity,temperature and rock mechanics of the res- ervoirs,and integrating filtration mechanics with rock mechanics.Despite the co- mplicate nature of the equations,non-linearity of unknown functions and presence of unknown boundaries(fractures),the finite element method for alternating solu- tions has been applied with success and satisfactory results obtained in calculation. Also discussed are...

Method of numerical analog is discussed.A set of equations is worked out co- nsidering the thickness ,heterogeneity,temperature and rock mechanics of the res- ervoirs,and integrating filtration mechanics with rock mechanics.Despite the co- mplicate nature of the equations,non-linearity of unknown functions and presence of unknown boundaries(fractures),the finite element method for alternating solu- tions has been applied with success and satisfactory results obtained in calculation. Also discussed are the opening of fractures in reservoirs nearby the bottom of injection wells,size of fractures,contribution of fractures to the absorbability of reservoirs and interferences between the multi-fractured zones etc.in respect to the application of the method in sandstone reservoirs under high-pressure water flooding.Clarification of all these problems may help determine a reasonable range of water-flooding pressure.

本文在大庆油田提高压力注水的情况下,应用数值模拟方法研究了注水井油层垂直和水平裂缝产生的条件,裂缝的大小,裂缝对油层吸水能力的改善,以及多层裂缝之间的干扰等问题。提出研究合理注水压力范围的重要意义。

This paper, dealing with some pipeline fracture accidents having occured in China a few years ago, is made up of four parts: The first part relates the transition temperature; the second and third ones the criterion of ductile fracture initiation and some factors that influnce the fracture; the last one touches on some problems about fracture arrest.

本文结合我国几年前曾发生过的一些管道断裂事故,分四部分进行了论述:第一部分谈到转变温度,第二三部分讲述了延性断裂起裂的判据和影响断裂的几个因素,最后谈到止裂问题。

This paper presents a mathematical mode of nonsteady flow to a well through, the three-fold media(which has three, constituents: matrix, fractures and vugs).Analytical solutions of flow problems with constant bottom-hole pressure are obtained by more convenient and powerful successive transformations (Laplace-Exteaded Weber and Laplace-finite Hankel).

本文给出粗裂缝(裂隙)——微裂缝——孔隙三重介质不稳定定径向流数学模型,并利用简便的Laplace—“护展”Weber双重积分变换以及Laplace—有限Hankel变换给出井底定压的精确解。
