| 1 | 浅薄层特超稠油开发后期蒸汽驱注采参数优化显示文摘浅薄层特超稠油具有埋藏浅、厚度薄、黏度大、分布散的特点,属于低品位稠油,开采十分困难。特别是到开发后期,由于气窜和地下剩余油分散,导致含水率急剧上升、产油量快速下降。但此时的采收率并不高,地下仍有大量剩余油资源。以河南油田为例,通过对矿场蒸汽驱实验效果的分析,利用数值模拟技术,对注采参数进行了优化:转驱的最佳时机是第9周期后;采用间歇汽驱效果相对较好;当周期注汽速度为120 m^3/d,注汽量为16 144 m^3,间歇时间为50 d时,开发效果最好。 | 霍梦颖 邵先杰 武宁 朱明 彭英明 | 2017 | 重庆科技学院学报(自然科学版)2017，19，5： | 5 |
| 2 | 全开放式单边核磁共振技术研究及系统开发显示文摘为了在单边磁体产生的逸散磁场中实现核磁共振技术,信号检测深度能满足相关应用需求,该文分析了非均匀磁场下的核磁共振技术条件,确定射频场目标,设计了单边平面射频线圈和探头,搭建出一套单边核磁共振实验系统.探头具有短脉宽(90°脉宽2.5μs),系统死时间短(10μs)的特点,可实现15μs的半回波时间.应用该系统,在15.3 T/m的巨大梯度磁场下,实现接近5 mm厚度的信号检测,并利用单边磁体的自然梯度磁场,开展了恒定梯度磁场下的扩散测量方法探索.结果表明,该系统可满足需要一定探测深度的领域的应用需求. | 汪红志 刘翔 苗志英 陈珊珊 施群雁 徐罗元 陆治勇 刘利荣 杨培强 | 2014 | 波谱学杂志2014，31，4： | 3 |
| 3 | Diffusion coefficients of natural gas in foamy oil systems under high pressures显示文摘The diffusion coefficient of natural gas in foamy oil is one of the key parameters to evaluate the feasibility of gas injection for enhanced oil recovery in foamy oil reservoirs.In this paper,a PVT cell was used to measure diffusion coefficients of natural gas in Venezuela foamy oil at high pressures,and a new method for determining the diffusion coefficient in the foamy oil was developed on the basis of experimental data.The effects of pressure and the types of the liquid phase on the diffusion coefficient of the natural gas were discussed.The results indicate that the diffusion coefficients of natural gas in foamy oil,saturated oil,and dead oil increase linearly with increasing pressure.The diffusion coefficient of natural gas in the foamy oil at 20 MPa was 2.93 times larger than that at 8.65 MPa.The diffusion coefficient of the natural gas in dead oil was 3.02 and 4.02 times than that of the natural gas in saturated oil and foamy oil when the pressure was20 MPa.However,the gas content of foamy oil was 16.9times higher than that of dead oil when the dissolution time and pressure were 20 MPa and 35.22 h,respectively. | Yan-Yu Zhang Xiao-Fei Sun Xue-Wei Duan Xing-Min Li | 2015 | Petroleum Science2015，12，2： | 1 |
