王官屯油田官三断块水淹层判别研究

Research on water flooded layer recognition in Guan-3 fault block of Wangguantun oilfield

王官屯油田官三断块经过近30年开发,区块产能逐步下降,层系内一类油层储备越来越少。随着开发技术的进步,层系内可动用低产油层、油水同层等之间成为后期接替层系。通过研究王官屯油田官三断块层系内低产油层、油水同层发育状况,提出在新背景下开发方式,为后续断块稳产打下坚实的基础。

Having been developed for nearly30years,and the capacity of Guan-3fault block in Wangguantun oilfieldis gradually decreasing and Class I reservoir reserves within the layer series is on the decrease.With the progress of developmenttechnology,producing low-production oil layers and oil-water layers within the layer series have become the replacement layer seriesin the late stage.Therefore,this paper mainly researches the development situation in the Guan-3fault block layer series and putsforward a new development way in the new background for the stable production in sequent fault blocks.
