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

利用计算机程序分析处理了中原油田36口井的斯仑贝谢地层倾角测井仪所测的双井径及相应的测臂方位曲线, 根据孔壁优势崩落方向推断出中原油田所在的东淄凹陷内构造应力场的主应力方向。研究发现, 最大水平主压应力方向在凹陷北部为N(796)W,而在南部为N(798)E,二者相差22左右。利用线弹性平面应力有限单元模型模拟本地区应力场的结果说明, 凹陷区较软的介质和北窄南宽的几何形状可能是引起凹陷北部最大水平主压应力方向相对于周围构造主应力方向产生一顺时针角度偏转的原因。根据某井孔出现明显径向不对称孔壁崩落的起始深度估计了最大和最小水平主压应力大小的取值范围, 展示了反映应力状态随地点和深度而变化的证据。 相似文献
