美国雪佛龙公司承包商HSE管理的经验与启示 总被引:1,自引:1,他引:0
通过对美国雪佛龙公司担任作业者的川东北天然气项目承包商HSE管理模式的调查研究,分析雪佛龙公司在川东北天然气项目中对承包商HSE管理的主要做法,包括资质预审、承包商选择、作业前风险评估、承包商培训、作业过程监督、承包商评价、承包商审计、承包商正向激励等。在此基础上,针对国内石油石化行业承包商HSE管理中的难点问题提出建立完善多元化承包商选择机制、内部承包商绩效评价机制、承包商管理人员培养机制、承包商管理工作标准及程序、承包商管理信息化系统等对策措施。 相似文献

含汞气田汞污染控制技术研究 总被引:1,自引:0,他引:1
痕量组分汞可能出现在大多数天然气气藏中。汞及其化合物均是剧毒物质,在含汞天然气处理过程中可能危害操作人员健康、腐蚀管线设备以及污染环境。针对某气田含汞天然气处理工艺,分析汞在天然气处理过程中分布情况,评价汞对天然气处理工艺及环境的影响,提出了含汞气田汞污染的控制技术以及防护措施,对降低含汞气田开发风险、保护人身健康及防止环境污染具有现实意义。 相似文献

灰岩区是当前地震勘探施工的难点地区。激发因素是地震勘探施工最直接的方法,也是人们进行试验所关注的焦点。虽然前人在灰岩区进行多年多次激发因素试验的选择上取得了一些共识,但仍然没有取得重大突破。在川东北南江地区的地震试验采集施工中,根据多项表层结构调查资料,在一些特定地区进行了有针对性的对比试验,如超大井深试验、超大药量试验、多井组合试验、岩性对比试验、不同封井方式试验、含水性激发试验、不同爆速的炸药类型试验等。在此基础上,提出了在不同条件下对灰岩区需采取的激发因素。 相似文献

气田开发对环境的影响及减少措施 总被引:1,自引:1,他引:0
在天然气的开发过程中,钻井会造成地层结构、地貌和植被(或农作物)的破坏,采气会使地层压力下降,地层压力平衡状态被打破。西南油气分公司通过生产实践,详细探讨了钻井对环境的影响;天然气开采对地层的影响;气田水对环境的影响;SO2对环境的影响;井下作业废液对环境的影响;降低气田开发对环境影响的措施。 相似文献

The water vulnerability of metro and megacities: An investigation of structural determinants 下载免费PDF全文
Thomas Bolognesi 《Natural resources forum》2015,39(2):123-133
Urban areas are becoming increasingly subject to and vulnerable to water‐related natural disasters. Urban areas are a kind of socio‐ecological system wherein the human development dynamics co‐evolve with the natural dynamics. Most of the literature is focused on the impact of natural disasters on human development; we evaluate the impacts of human development on natural disasters and present an analysis of this phenomenon in the context of megacities. The approach is exploratory and begins with the construction of a database on the 595 existing megacities in the world. Multifactor analysis is then used to determine the main characteristics of these megacities. Finally, three structural components (maturity, anthropization and centrality) are identified and then correlated with data on water‐related hazards, distinguishing groups of cities according to their structure and factors of vulnerability to water‐related risks. 相似文献

The impacts of natural disasters on communities living in hazard prone areas are wide ranging and complex. In Mwanza, steep slopes, rocky hills and river valleys are inhabited by society's poorest people. These areas are prone to natural disasters. Residents have accumulated coping mechanisms for disaster risks and impact reduction. We combine spatial data, household surveys and data from focus groups to identify and rank areas based on their exposure to major disasters. We also examine household and communal mitigation efforts in relation to these disasters. Most areas of the city are exposed to at least one of the natural disasters studied. Pre- and post-disaster risk reduction measures are influenced by the site of homesteads and the socioeconomic situation of households. Current resilience measures are skewed towards the development of physical infrastructure. The challenge of reducing disaster risks in Mwanza involves recognizing the role of non-infrastructure based factors that promote urban resilience to natural disasters. 相似文献
