作为一项钻井新技术，小眼井钻井可大幅度降低钻井成本,正愈来愈受到国内外各油气田的重视。小眼井钻井技术在中原油田主要用于φ139.7mm套管开窗侧钻井裸眼段的钻进，根据中原油田20余口φ139.7mm套管开窗侧钻井的钻井实践，探讨了中原油田φ118mm井眼钻 井的若干技术问题，其中包括钻头选择、钻井参数的优选、钻具组合和轨迹控制、固井技术及井下复杂情况和事故处理技术等。     

Effect of misalignment on electrical characteristics of ACF joints for flip chip on flex applications

The effect of misalignment on the electrical properties of anisotropic conductive film (ACF) joints is investigated in this work. It is found that along with the increase of misalignment, the connection resistance of ACF joints increases. When the misalignment in x-direction is less than 5 μm, the increase rate of connection resistance is quite large. Then, along with the severity of misalignment, the increase rate becomes smaller. Finally, when the misalignment is close to 20 μm, the increase rate rises again. The Holm's electric contact theory is used for understanding the connection resistance variation. On the other hand, with the increase of misalignment in x-direction, the insulation resistance between ACF joints decreases. If the misalignment exceeded 10 μm, the decrease is prominent for the Ni particle ACF joints. This phenomenon can be explained by the effect of dielectric damage of the epoxy.Computer programs are also developed to calculate the variation of the probability of open and shorting after misalignment and predicate the maximum misalignment tolerance. The results show that the open and shorting probability increase abruptly after misalignment. On the view of pad parameters, the open probability is mainly related to the pad area, while the pads gap is critical to the shorting probability. Large pads gap (small pad width) can reduce the shorting probability obviously. On the other hand, enlarging the pad area by increasing pad length decreases the open probability significantly. So comparing to square shape pad, rectangle shape pad can reduce the failure probability greatly.

管材拉伸模具定径区摩擦力的探讨

管材拉伸时把模具定径区看作准塑区，利用塑性条件，研究定径区摩擦力对拉伸力的影响，并对计算公式进行探讨。证明管材空拉（减径不减壁）时摩擦力影响可忽略不计，但减径、减壁拉伸同时进行时，定径区摩擦力对拉伸力的影响就必须考虑。

The Synthesis of Sulfated Titanium Oxide Nanotubes

TiO₂ nanotubes can be prepared in gram quantities by treating anatase TiO₂ powder with concentrated NaOH solution. These TiO₂ nanotubes acquired strong acidity after being impregnated with sulfuric acid solution and calcined at 300 °C. The anatase TiO₂ powder used to prepare the nanotube did not catalyze the esterification between cyclohexanol and acetic acid, while sulfated TiO₂ nanotubes were very reactive toward the esterification reaction.
