地下含水层热储井位置选择和布置

地下含水层热储开发技术面临一系列问题,寻找适合热储用的含水层和合理布置热储井是解决问题的第一步.综合考虑含水层的地质结构特征,适合热储的含水层应该是承压含水层,热储应该采用同层方式.单个热储井的影响半径可以通过热平衡和热扩散原理求得.合理布置热储井间的相对位置,可以有效抵消原有地下水的流动以及渗流系数不一致的影响.利用井之间的渗流耦合作用,在热储井之间布置调节井,主动控制热储水的波及范围,可以实现热储井布置的相对"紧凑".     

Optical Recording Properties of Metal-Azo Dye as Recording Medium with Super-Resolution Near-Field Structure

A novel metallized azo dye has been synthesized. The absorption spectra of the thin film and thermal characteristic are measured. Static optical recording properties with and without the Bi mask layer super-resolution near-field structure （Super-RENS） of the metal-azo dye are investigated. The results show that the metal-azo dye film has a broad absorbance band in the region of 450-650 nm and the maximum absorbance wavelength is located at 603 nm. It is also found that the new metallized azo dye occupies excellent thermal stability, initiatory decomposition temperature is at 270℃ and the mass loss is about 48% in a narrow temperature region （15℃）. The complex refractive index N （N = n ＋ iκ） is measured. High refractive index （n = 2.45） and low extinction coefficient （κ = 0.2） at the recording wavelength 65Ohm are attained. Static optical recording tests with and without Super-RENS are carried out using a 65Ohm semiconductor diode laser with recording power of 7mW and laser pulse duration of 200ns. The AFM images show that the diameter of recording mark on the dye film with the Bi mask layer is reduced about 42%, compared to that of recorded mark on the dye film without Super-RENS. It is indicated that Bi can well performed as a mask layer of the dye recording layer and the metallized azo dye can be a promising candidate for recording media with the super-resolution near-field structure.
