聚合物与水气交替联驱提高采收率试验研究

采用三种不同沉积韵律平面模型试验研究水驱后聚合物与水气交替联驱提高原油采收率的驱替特征。结果表明,聚合物与水气交替联驱对正韵律油藏提高采收率效果很好;对反韵律油藏和复合韵律油藏也有不同程度提高采收率效果。通过分析两种不同韵律砂岩油藏水气交替提高采收率矿场试验成功实例,认为聚合物与水气交替联驱法可综合发挥两种方法的优势,在类似油藏中比单一方法有更好的提高采收率效果。

Adsorption separation of condensate oil from produced water using ACTF prepared of oil palm leaves by batch and fixed bed techniques

A novel method is applied to produce amorphous carbon thin film (ACTF) from oil palm leaves. The novel prepared ACTF is in the form of thin films like graphene sheets having winding surface. ACTF was characterized by different methods of characterization: FTIR, BET, SEM, EDX, TEM, and Raman. ACTF employed as an adsorbent to separate emulsified condensate oil from synthetic produced water as a treatment process before reinjection in oil reservoirs. The adsorption performance of batch and fixed bed adsorption systems were investigated. Contact time, initial concentration of condensate oil ($C_o$ = 100–2500 mg/l) and temperature were studied by batch experiments. The obtained results indicated that the adsorption capacity and the removal efficiency increased with time up to 132.77 mg condensate/g adsorbent and 66.38% respectively, within 6 h equilibrium time at 308 K. The thermodynamic adsorption experiments conducted at 288, 308 and 318 K, referring exothermic nature of the adsorption process.The performance study of fixed bed adsorption described through the breakthrough curves concept with two parameters: column bed heights (5, 10 and 15 mm) and flow rate (2.2, 5 and 8.4 ml/min). Two models (Thomas and Yoon-Nelson models) were applied to expect different parameters of fixed bed as adsorption capacity and time need for 50% breakthrough. The results exhibited that 2.2 ml /min feed flowrate and 5 mm bed height at 1000 mg/l initial oil condensate concentration were the optimum conditions for the ACTF column. The experimental breakthrough curves showed acceptable fit with the calculated breakthrough profiles obtained by Thomas model.

聚合物驱后地层残留聚合物絮凝再利用技术研究

河南双河油田北断块Ⅱ4.5注聚结束时大量聚合物残留在地层中,聚合物的浓度分布在200—600mg／L之间。聚合物驱后恢复水驱,注入水沿高渗透层窜流,含水率迅速上升。针对双河油田聚合物驱之后出现的实际问题,研究了一种可以进一步提高采收率的采油技术——聚合物絮凝再利用技术。该技术是利用地层残留低浓度聚合物对絮凝荆的桥接吸附作用形成絮凝体封堵高渗透层,达到深部调剖、提高水驱采收率的目的。通过室内实验,筛选出的最佳絮凝剂为3wt％稳定化钠土（YG340-1）,且絮凝荆越旱注入对聚合物再利用效果越好。该项技术已在双河油田进行了矿场试验,并取得了较好的效果,具有广阔的应用前景。
