  vertical
In order to deal with large problems, a pair of trust region subproblems in horizontal and vertical subspaces is used to replace the general full trust region subproblem.
      
The horizontal trust region subproblem in the algorithm is only a general trust region subproblem while the vertical trust region subproblem is defined by a parameter size of the vertical direction subject only to an ellipsoidal constraint.
      
That is, the plot with the fitted response ? on the horizontal axis and the observed y on the vertical axis can be used to visualize the link function.
      
It was found that the vertical magnetic anisotropy would drop lineally with the increase of the array diameter.
      
In contrast, under AFM nanoindentation mode, the tip-induced crystallization occurred when a sufficiently high vertical tip force was applied to the melt droplets of PEO with Mn ? 1.0 × 104 g/mol.

This paper introduces a math model of by-passing flow concerning the ideal gas and real gas produced from the upper permeable reservoir separated from the lower per meable reservoir by a dense intercalation with low permeability and both of the reservoirs may be of single medium or double porous media. The accurate solution of infinite formation and the long-term asymptotic solution applied on the spot are obtained from this math model, from which the interpretation and analysis of the buildup curve, vertical...

This paper introduces a math model of by-passing flow concerning the ideal gas and real gas produced from the upper permeable reservoir separated from the lower per meable reservoir by a dense intercalation with low permeability and both of the reservoirs may be of single medium or double porous media. The accurate solution of infinite formation and the long-term asymptotic solution applied on the spot are obtained from this math model, from which the interpretation and analysis of the buildup curve, vertical interferenc test and vertical pulse well testing of the individual well and multi-well of gas pool with single medium or double porous media are performed.

Xihepu formation (miocene) of Kokeya condensate field can be divided into two members, upper member and lower one. The former, indicated as X_4~2—X_5~2, sequenel, is a secondary oil-gas condensate reservoir with edge water and oil-ring gas cap. During the production, it is recognized that there were three periods of the reservoir pressure, i. e, stable, fall-off and build-up periods. The change in pressure gradient was evidently controlled by its edge water horizontally or vertically.Belonging to fluvial sedimentary...

Xihepu formation (miocene) of Kokeya condensate field can be divided into two members, upper member and lower one. The former, indicated as X_4~2—X_5~2, sequenel, is a secondary oil-gas condensate reservoir with edge water and oil-ring gas cap. During the production, it is recognized that there were three periods of the reservoir pressure, i. e, stable, fall-off and build-up periods. The change in pressure gradient was evidently controlled by its edge water horizontally or vertically.Belonging to fluvial sedimentary facies, this reservoir is characterized by serious heterogeneities with permeability changing from higher for the lower to lower for the upper, and the horizontal higher than the vertical. However, no cross flow occurred between zones. The effect of the edge water and gas cap on the properties of its oil-gas condensate has been variable during the period of production and, with increase of oil-gas ratio, the content of condensate was reduced generally.

柯克亚凝析油气田上第三系中新统西河甫组分上、下两套油组。上油组X_4~2—X_5~2开发层系为具边水、气顶带油环的次生凝析油气藏,地层压力在开发过程中分稳定期、衰减期和回升期三个阶段,平面或垂向的压力梯度变化明显受边水驱控制。 X_4~2—X_5~2储层属河流相沉积,非均质性严重,渗透性能具有下大上小、水平渗透率高于垂直渗透率的特点,但层间不存在窜流现象。开采过程中,油气性质受边水和气顶影响,变化不一;生产油气比不断上升,凝析油含量普遍下降。

Finite element method has been used to study the flow characteristics of perforated wells and to investigate perforator penetration and damage mechanism in combination with core target experiments. Establishment of a finite element mathematical model for a core perforation and its numerical solution are presented in detail. The effect on productivity ratio and skin factor of depth of penetration, hole diameter, hole density, phase, format, damage depth, damage percentage, compaction zone depth, compaction perc entage, wellbore radius, drainage boundary radius, K_z/K_r ratio, bottom hole pressure, boundary pressure and production pressure difference is considered in the mathematical model. Grid sensitivity analysis ensures convergence and accuracy of calculation. An example is given to illustate the flow behavior of the core target, and the effect of perforating parameters on productivity ratio is analyzed. The table listed in API RP 43 is shown by calculation, electric modelling and core target experiment to be less reliable. Revision of these data will help evaluation of core flow efficiency. Compaction zone permeability can also be obtained by back calculation.
