摘要: 油水同采技术是国外20世纪90年代发展的一项新技术,用以消除或抑制底水油藏中油井的水锥。运用数值模拟方法,研究确定红南边底水油藏的油井应用油水同采技术的合理时机为含水率30%~40%,射开水层的位置为油水界面附近,最信水油比为3:1,通过红南油田3口井实际应用效果评价显示,油水同采技术对控制油井舍水率上升、稳定油井产量、提高采收率有较好的效果。

Abstract: Oil-water simulaneous production, a new technology developed abroad since 1990s, is primanily applied to eliminale or control water coning in reservoir with botom water. With numerical simulation method, it is preferred ihat the proper time of oil- water simultane-ous production is when water cut reaches 30%~40%, the reasonable perforation position in water layer is near oil-water contact, the best water- oil ratio is 3:1. Three-well response evaluation shows that oil-water simultaneous production can effectively control raise of water cut, make oil production stable and enhance oil recovery.

Key words: Tuha basin, edge water, bottom water, technology, water coning
