榆树林油田是特低渗透、低产能的油田。油井压裂投产后初期产量较高 ,但油层压力和产量下降速度快 ,并且压力、产量降低之后恢复起来十分困难。为提高油田开发效果 ,使油井产量稳定在较高水平上 ,在室内实验研究的基础上 ,1 993年在树 34井区开展了同步注水开发试验 ,并在其它区块逐步推广 ,取得了明显效果。 Yushulin Oilfield is a very low permeability, low productivity oil fields. Oil well fracturing put into operation after the initial high output, but the reservoir pressure and output decline rapidly, and the pressure, reduce the output recovery is very difficult. In order to improve the oilfield development effect and stabilize the oil well production at a relatively high level, on the basis of laboratory experiments, a synchronous water injection test was conducted in Shu 34 well area in 1993 and was gradually popularized in other areas with obvious effect.
