新庄油田XQ45区属于浅层小断块特稠油油藏,2005年投入开发以来,随着吞吐周期的增加,近井地带含油饱和度降低,束缚水饱和度增加,蒸汽热效率降低,造成周期生产效果逐渐变差、汽窜严重、井下故障增加。2006年以来,对XQ45区采取了如下综合治理措施:提高注汽压力,保障注汽速度;面积组合注汽与局部调剖、返层结合;高含水及故障井治理。并对综合治理效果进行了分析,提出了下步措施优化意见。 The XQ45 area of ​​Xinzhuang Oilfield belongs to the superfamily small fault block heavy oil reservoir. Since it was put into development in 2005, with the increase of the throughput period, the oil saturation in the near well bore decreases, the irreducible water saturation increases and the steam thermal efficiency decreases, resulting in the cyclical production The effect is getting worse, steam channeling serious, downhole fault increases. Since 2006, the XQ45 zone has taken the following comprehensive measures: Increasing the pressure of steam injection and ensuring the speed of steam injection; Combined steam injection with local profile control and return layer combination; Control of high water cut and fault wells. And the effect of comprehensive management was analyzed, and the suggestions of next step optimization were put forward.
