Zaloni油田ZaloniBarailSecond砂岩油藏是1957年发现的。为了保持压力,1973年通过将水注入含水层进行了边缘注水。1975年12月在该油藏实施了聚合物驱项目。该油藏的目前采收率约为原始原油地质储量的42%。为了提高最终采收率,2003年进行了多学科综合研究,以便寻找更多的提高采收率的机遇。于2004年7月在油藏钻了一口加密井,该井的纯油采油量为45m3/d。由于从该油藏未泄油区域/未波及区域成功采油,延长了该油藏的开采期限,所以不仅在该油藏而且还在附近未泄油区域钻了更多的加密井。
Zaloni Oilfield ZaloniBarailSecond sandstone reservoir was discovered in 1957. In order to maintain the pressure, edge water injection was carried out in 1973 by injecting water into the aquifer. In December 1975, a polymer flooding project was implemented in this reservoir. The current recovery rate of this reservoir is about 42% of the original crude oil geological reserve. In order to increase the final recovery, a multidisciplinary and comprehensive study was conducted in 2003 to find out more opportunities for enhanced oil recovery. In July 2004, an oil well was drilled in an oil well with a pure oil production of 45 m3 / d. Due to the successful oil recovery from the undeveloped / undeveloped areas of the reservoir, the period of exploitation of the reservoir was prolonged, so more infill wells were drilled not only in the reservoir but also in the nearby unexploded area.
