Iridium (III) complexes have broad application prospects in luminescence detection of analyte due to advantages of large Stokes shift, high quantum yields, long luminescence lifetimes, flexible and adjustable emission spectra, and excellent optical and thermal stability. The novel iridium(III) complex Ir(ppyTPA)₃ was prepared by introducing triphenylamine substituent on 2?phenylpyridine, and the structure, luminescence and electrochemical properties of Ir(ppyTPA)₃ were characterized in detail. Then, the luminescence properties of Ir(ppyTPA)₃ were used to detect five common nitroaromatics and the detection mechanism was studied. The results show that Ir(ppyTPA)₃ has the highest detection efficiency to 3?nitrobenzoic acid with the detection efficiency constant K_SV of 19.78 L/mmol. And the detection limit is as low as 2.89×10^-3 mol/L. Spectral analysis and density functional theory calculations show that the detection mechanism of Ir(ppyTPA)₃ for the five nitroarenes was the charge transfer mechanism.

β?cyclodextrin polymers modified with Fe₃O₄ (β?CDP@Fe₃O₄) was synthesized in alkaline medium using β?cyclodextrin (β?CD) as monomer and epichlorohydrin as crosslinker. The adsorption performances of β?CDP@Fe₃O₄ on bisphenol A (BPA) under static and dynamic conditions were investigated. The results of static experiment show that the adsorption performance of 100 mg/L BPA (pH=5.6) is best at 0.10 g β?CDP@Fe₃O₄. At this point, the equilibrium adsorption capacity, adsorption rate and the maximum adsorption capacity are 45.600 mg/g, 91.3%, and 113.600 mg/g, respectively. The results of dynamic experiment show that the smaller the liquid hourly space velocity, the higher the adsorbent utilization rate, and with the increase of BPA concentration, the adsorption breakthrough time and saturation time are declined. At the same time, the synthesis and adsorption mechanism of β?CDP@Fe₃O₄ were discussed. A rapid adsorption rate for the removal of BPA onto β?CDP@Fe₃O₄ from water solution was achieved, and the adsorption process was mainly due to hydrogen bond and hydrophobic interaction. β?CDP@Fe₃O₄ has good regenerative performance, through 6 cycles of static adsorption?desorption, and 3 cycles of dynamic adsorption?desorption without significant changes in adsorption performance.

Taking well group M of E+K block of YH condensate gas reservoir as a typical example, a numerical simulation model of a typical well group was established to study the main controlling factors and mechanism of EOR by gas injection. The effects of different factors including injection?production positions, injection medium, gas injection volume, injection?production ratio, gas injection timing and pressure recovery degree, on the production performance was simulated and the gas injection scheme of the well group was optimized. The results show that the development of retrograde condensate gas reservoir is optimized under the conditions of "up?down production", cyclic gas injection, gas injection volume（30.50～36.60）×10⁴ m³/d （annual gas injection volume is 2.50%~3.00% of the original geological reserves） and maintain high formation pressure (depleted to no less than the dew point pressure). The research results can provide a basis for the policy formulation of EOR technology in the middle and late stage of gas injection development of YH retrograde condensate gas field and provide guidance for the development adjustment of the gas field in the middle and late stage.

Metal organic framework ZIF?67 has been successfully fabricated via solvothermal method. The as?synthesized ZIF?67 was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X?ray powder diffraction and thermogravimetric analysis. The adsorption property of ZIF?67 for methyl orange was investigated. The effects of pH value, dosage of adsorbent, initial concentration of methyl orange solution, contact time and temperature were discussed. The results show that the most proper dosage of ZIF?67 is 20 mg. When the pH value of the dye solution is 7, the adsorption capacity is the best. At 303 K, the adsorption reached an equilibrium within 25 min. The maximum adsorption capacity of ZIF?67 for methyl orange is 152.67 mg/g at 303 K. The isotherm data followed the Langmuir isotherm model and the kinetic adsorption obeyed the pseudo?second?order model. Thermodynamic parameters illustrated that the adsorption process is spontaneous and endothermic. The spent ZIF?67 has excellent regenerative performance by treating with ethanol, and the adsorption ability of ZIF?67 remains good after six adsorption?desorption cycles.

Water-driven oil in porous media fluid and solid coupled heat transfer control equations was established by the theory of percolation mechanics and the sandstone reservoir was porous medium. Different well pattern was established for the same reservoir numerical simulation, qualitative analysis of the process of oil pressure, the remaining oil distribution, and the various concentration range the proportion of oil, quantitative analysis of the volume fraction of the sum of the remaining oil and various oil recovery year. The results show that 5 to 9 years of oil remaining oil distribution changed in the inert area, during this time recovery changed smoothly; Analysis of a variety of oil recovery wells arrangement size was that five-spot well pattern was larger than nine-pot well pattern, and nine-spot well pattern was larger than Line shape well pattern. When the water intensity constant, from the perspective of recovery. For this reservoir five-spot well pattern was the best well pattern.

Glutamate acid fermentation waste water is a kind of high concentration organic waste water formed during producing monosodium glutamate, which has complicated ingredients and is hard to process. The main treatment technology was introduced. The present status of comprehensive utilization of monosodium glutamate waste water was described. The viewpoint was summarized and expatiated that treatment of glutamate waste water should be combined with comprehensive utilization and cleaner production. This is a new technique development trend of glutamate waste water treating. And a new kind of technique of glutamate waste water treatment is put forward to combine with the whole comprehensive utilization.
