提高葡南扶余油层动用程度技术探讨

The Technical Discussion About Improving the Use of Fuyu Block in Punan Oilfield

经过几年的开发实践,葡南扶余油层区块具有总体开发效果欠佳的特征,其主要原因是低孔特低渗透的扶余油层动用程度相对较低。参照低渗透油田的渗流特征与常规开发对策,发现在扶余油层开发中存在着孔隙、油层、井网、油田注水等方面的问题,提出加强油层保护、热采与笼统注水及井网调整试验、点源开发技术兼顾开发葡萄花油层等方法,对有效解决葡南扶余油层动用难的问题具有积极的参考借鉴意义。

After years of development practice,it is poor on overall development effectiveness at Fuyu block in Punan oilfield.The main reason is relative low in the use of Fuyu layer,which is low porosity and low permeability.Reference to the flow characteristics and conventional development strategies of low-permeability oil fields,it is found that there are some problems in the development of Fuyu layer,such as pore and reservoir and well network and oilfield injection etc.To solve these problems,it is necessary to take the following technical measures,enhancing reservoir protection,making field test on thermal production and general injection and adjust well network,and applying the point-source development technologies and taking into account the development Putaohua layer.These technologies has a positive reference to solve the difficult problem about the use of Fuyu layer in Punan field.
