中原油田开采40多年来,已由最初单纯的油气开采逐渐转向多元化经营,形成了集油气开发于一体的产业链,在为经济社会发展提供能源的同时,石油的开采也对油区周围的土壤和生态环境造成了破坏。由于历史上的种种原因,这些问题始终没有得到有效解决。 相似文献

中原油田高压注水诱发的油水井套管损坏原因分析 总被引:2,自引:0,他引:2
中原油田高压注水开发35年,套管损坏严重,严重的影响了油田的开发效果。据研究,油田水井套管损坏主要有错断、变形及破漏等三类,平面上主要分布在断层发育区、高地层水矿化度区、泥岩层和盐膏层发育区,剖面上主要分布在盐膏层段和主力生产井段。提出断层活动、地应力非均质演化、盐岩蠕变、油田开发历程和开采方式及油气流场、化学场演化是中原油田套损的主要控制因素,建立油田油藏油井多参数动态模式,优选与油藏模式匹配的开采方式及增产措施,改造套管动力学环境和化学环境将能防治套损地质灾害的发生。 相似文献

Pollution characteristics of polycyclic aromatic hydrocarbons (PAHs) in oily sludge from the Zhongyuan Oilfield and its peripheral soils 总被引:1,自引:1,他引:0
The purpose of this study is to determine the degree of contamination caused by polycyclic aromatic hydrocarbons (PAHs) in
oily sludge and soils around it in the Zhongyuan Oilfield. The contents of polycyclic aromatic hydrocarbons in oily sludge
samples were determined with HPLC. The contents of PAHs of oily sludge from three different oil production plants vary from
high to low in the order of the Wenming oily sludge dumping site of No. 3 Oil Production Plant (3W)>the Mazhai oily sludge
dumping site of No. 3 Oil Production Plant (3M)>the Wen’er oily sludge dumping site of No. 4 Oil Production Plant (4W). Naphthalene,
acenaphthylene, acenaphthene, fluorine and phenanthrene are the major pollutants of PAHs in oily sludge. The contents of PAHs
in soil samples around the oily sludge dumping sites vary widely from 434.49 to 2408.8 ng/g. Naphthalene, acenaphthene, fluorine,
phenanthrene and pyrene are the characteristic factors of PAHs in soil samples of 3M and 3W, and naphthalene, acenaphthene,
fluorine and phenanthrene are the characteristic factors of PAHs in soil samples of 4W. According to these data and the ratios
of Fl/Py, PAHs in oily sludge samples come mainly from petrogenic sources, and soil samples are divided into petrogenic soil
samples and mixed-source soil samples, and both petrogenic and pyrogenic soil samples in terms of the sources of PAHs. The
classification by Nemero index P indicates that soils around the oily sludge dumping sites have been seriously polluted. 相似文献
