陆相储层油田开发工程灾害特征及成因机理——以松滋油田A区为例

基于松滋A区油田工程灾害统计资料,开展陆相储层油田开发工程灾害特征和成因机理研究。以油田开发过程中出现的工程灾害事件"套管损坏"为例,通过比较不同地下地质结构油区工程灾害发育特征的差异,从储层性质、矿物成分、沉积相等入手,分析地下地质结构与套管损坏、油层出砂等工程灾害之间的内在联系;从理论角度分析灾害成因机理,探讨在油田开发注水情况下,地下地质结构对工程灾害的控制和影响;并从工程角度,提出预防和控制灾害的对策和建议。

The Characteristics and Forming Mechanism of Engineering Disasters in Terrestrial Oil Field Development: with "A " Section of Songzi Oil Field as an Example

On the basis of the data statistics of engineering disasters in "A" section of Songzi oil field and with the disaster of casing failure as an example,the differences of disasters developing characteristics among different geological structures are compared.From the aspects of reservoir mineral composition,sedimentary phase and reservoir characteristics,the internal relation between the underground geological structure and the reservoir engineering disasters,such as sand production,casing damage,etc.is analyzed.The forming mechanism of engineering disasters is studied from theoretical aspect,and the effect of underground geological structure on engineering disasters under water injection development is discussed.Finally,engineering prevention and control measures are presented.
