黑河分水计划对临泽绿洲种植业结构调整及生态稳定发展的影响——以黑河中游的临泽县平川灌区为例

黑河分水计划及用水商品化的实施,对绿洲种植业结构调整、节水降耗和退耕,有着较大的积极作用.但也相应出现了一些不可忽视的问题,如在调水方式及适宜时段的合理选择、供需水之间矛盾的有效处置以及流域水资源合理高效利用模式的建立等方面还有待进一步研究.特别是在水资源短缺和市场经济的双重作用下,过度开采地下水以及追逐短期利益行为有所加重,进而导致地下水位波动性变化幅度加大和低效的公益性生态建设与发展受到较大的制约,尤其是荒漠绿洲交错地带的生态环境及生产条件在分水后显现诸多不适宜或退化迹象,并有恶化发展的趋势.     

Allocation of commingled pipeline oils to field production

This paper presents a case study of using oil fingerprinting technology to correctly back allocate commingled pipeline crude to production from six contributing fields in an offshore southeast Asia basin. A large number of oil and pipeline samples were collected over time and analyzed by gas chromatography for their oil fingerprints. In this case, production from each field pipeline could easily be distinguished by their whole-oil fingerprints that changed little with time. However, oils collected from the commingled pipelines showed significant chromatographic variation with time, indicating production contribution from the different fields to the pipelines varied with time. Quantitative results were attained using a proprietary computer program which mathematically calculates relative contributions (±3%) of oil mixes based on a best-fit least-squares regression of selected chromatographic peak ratios. This allocation method assisted operations to more accurately determine production for each field or a group of fields in the basin. The technique, which provides a new approach to supplement and cross-check production metering necessary for defining tax liability, has helped save significant tax dollars for field operation units.

SHORT COMMUNICATION USE OF METEOROLOGICAL DATA TO IDENTIFY EMISSOR SOURCES OF POLLUTANTS

A multivariate statistical analysis was performed by combining metal and anion data found in particulatematter from the atmosphere of Sant Adrià de Besòs(Barcelona)with SO_2,total suspended particle andsmoke values as well as with some meteorological measurements.Factor analysis allowed us in a previous work to recognize some emissor sources(soil,traffic,NO_x-SO_2,fuel oil,sea,incineration)by means of the analysis of some metals and anions.In the presentwork some meteorological data(temperature,humidity and sunshine),the concentration of SO_2 andvalues of total suspended particles and smoke were introduced into the correlation matrix in order tostudy their contribution to the identification of emissor sources.It was found that a decrease in temperature is in accordance with an increase in the presence of tracersfrom traffic emissions;chloride and humidity have a close correlation:SO_2 and sulphates come from thesame source;and oxidation from NO_x and SO_2 to nitrate and sulphate is higher with a decrease in thepercentage of sunshine.
