马寨油田卫95块经过长期的注水开发已进入特高含水开发期，综合含水95%以上。针对油田开发现状，引入HSG-1油藏流体流向控制技术，使用一种小剂量高强度深度封窜流向控制剂，在充分调剖基础上进行小段塞可运移油藏深部调剖堵水。在室内评价的基础上，于2007年底在卫95块8井组开展了现场应用试验，取得了较好的效果，增油1768 t，试验区块自然递减由2007年的16.8%下降为2008年的11.2%。该技术的应用成功，为类似油藏的开发提供新的思路和方法。

After a long periled of waterflooding, the Wei 95 block of Mazhai Oilfield has entered into an ultra-high water cut period, with the water cut higher than 95%. According to the development state of the Wei 95 block, the HSG-1 reservoir fluid flow control technology is employed. Deep profile control and water shutoff within small sections of reservoirs are conducted, based on using a kind of flow control agent for channeling sealing featuring in small dose, high intensity, and big depth. On the basis of laboratory test, field application of the technology was launched in 8 wells at the end of 2007, 1768 t of crude increment was fulfilled, and the natural decline dropped to 11.2% in 2008 from 16.8% in 2007. The success presents a novel thought and approach to the development of similar reservoirs.
