水平井技术在梁家楼油田挖潜增效中的应用

APPLICATION OF HORIZONTAL WELL TECHNOLOGY TO TAP REMAINING OIL IN LIANGJIALOU OILFIELD

梁家楼油田南区在高含水后期，应用水平井技术挖掘剩余油潜力取得显著成效。在水平井的地质设计、油藏工程研究和水平井的管理等方面均具有较高水平。前后投产６口水平井，平均初产是周围老井的１２倍，平均单井增油 １５ × １０４ｔ，提高采收率 ５个百分点。水平井技术是老油田后期挖潜的重要措施，并得以广泛应用。

Horizontal well technology was applied to tap remaining oil in later high water-cut stage in the south zone of Liangjialou Oilfield, and remarkable result has been obtained.High level has also been reached in many aspects including geological design of horizontal well, reservoir engineering study and management. 6 horizontal wells were successively put into production whose initial oil rate was 12 times as much as adjacent old wells'. Average raised oil of single well reached 1. 5 ×104t, and oil recovery coefficient raised by 5. 0%. In one word, horizontal well technology is a kind of major measure to tap remaining oil in later high water-cut stage, and should be extensively popularized.
