濮城特低渗断块油田综合开发方法探讨

The Discussion of Synthetic Development Technology in Pucheng Special Low Permeability Pools Oilfield.

针对濮城特低渗断块油田的地质特点,在开发过程中采用了双靶定向井钻井、油层保护、注采井网部署等系列配套技术。在进行综合开发方法探讨的同时,介绍了该油田沙三中6-10层系的成功开采方法,对同类油藏的开发具有一定的借鉴意义。

For low permeability oilfield in Pucheng, technologies, such as reasonable layout of pattern type, dual targeted orientational drilling, high pressure injection increase,early water flood for complement energy, high efficient perforation and bullhead fracturing and etc. are applied to improve pay zone and to prevent production well from being flooded in design of development. Down hole pumping with small power is used to enlarge draw down and increase off-take potential of production wells. The experierce in zones 6-10 of Es3 in Pucheng Oilfield can be used for reference in developing other oilfields with some characters.
