SYL-01破乳剂的合成及性能测试

在国内外研究的基础上通过实验以MAA、AA、BuAc、MMAc为原料，采用乳液聚合的方法合成了一种新型的不含烷氧基的水溶性W／O原油破乳剂SYL-01。反应条件与反应物的用量研究表明：反应物最佳配比为AA：MAA：BuAc：MMAC＝0．75：0．25：10：4。对原油乳液的破乳实验说明：SYL－01与目前使用的9901破乳剂性能相当，脱水率较高。SYL－01原料价廉易得，不使用易燃易爆的气体原料，工艺简单，有较好的开发应用前景。     

废弃水基钻井液的利用──MTC固井技术

治理与利用废弃钻井液是油气田环境保护的主要研究课题之一。MTC固井技术是在废弃钻井液中加入固化剂和化学处理剂使之转变为固井液，研究结果表明：只要固化剂、化学处理剂及配方选择得当，可使废弃钻井液转化为MTC固井液，这样既可节的固井成本，又为解决废弃钻井液的环境污染问题提供了一条行之有效的途径。

灰色聚类分析在环境质量评价中的应用

环境是一个“灰色系统”，可以将灰色聚类分析应用到大气环境评价中。灰色聚类可按６个步骤进行：①给出聚类白化值；②确定灰类的白化函数；③求标定聚类权；④求聚类系数；⑤构造聚类行向量；⑥聚类。将灰色聚类分析方法应用于某油田８个主要矿区的ＳＯ２、ＴＳＰ和ＮＯｘ污染物，得出它们的大气环境质量的相应等级。     

Establishing the link between ammonia emission control and measurements of reduced nitrogen concentrations and deposition

In the context of international efforts to reduce the impactsof atmospheric NH₃ and NH₄ ⁺ (collectively, NH_x), it is important to establish the link between NH₃emissions and monitoring of NH_x concentrations and deposition. This is equally relevant to situations where NH₃emissions changes are certain (e.g. due to changed source sectoractivity), as to cases where NH₃ abatement technologies havebeen implemented. Correct interpretation of adequate atmosphericmeasurements is essential, since monitoring data provide the onlymeans to evaluate trends in regional NH₃ emissions.These issues have been reviewed using available measurements and modelling from nine countries. In addition to historic datasets,the analysis here considers countries where NH₃ source sector activity changed (both increases and decreases) and countries where NH₃ abatement policies have been implemented.In The Netherlands an `ammonia gap' was identified between the expected reduction and results of monitoring, and was attributedinitially to ineffectiveness of the abatement measures. The analysis here for a range of countries shows that atmospheric interactions complicate the expected changes, particularly sinceSO₂ emissions have decreased at the same time, while at manysites the few years of available data show substantial inter-annual variation. It is concluded that networks need to beestablished that speciate between NH₃ and aerosol NH₄ ⁺, in addition to providing wet deposition, and sample at sufficient sites for robust regional estimates to be established. Such measurements will be essential to monitor compliance of the international agreements on NH₃ emission abatement.
