AdonRoad油田为无裂缝砂岩，油层温度高（79．4℃），渗透率变异系数较大（0．70）。在水驱初期就进行了深部胶态分散凝胶（CDG）技术处理。20个月内共注入CDG溶液564948bbl（8．03％PV），平均聚合物浓度268mg／L。随后17个月内注入未交联聚合物溶液556800bbl（7．91％PV），平均聚合物浓度150mg／L。实施效果非常明显，采油量上升，处理水量下降，注入达32．3％PV后，采收率为45．2％STBOOIP。而在相同条件下的水驱，采收率可达到27％STBOOOP，每增加一桶原油的化学剂成本为0．72美元，实际效果明显地优于方案预测。本文详细地讨论了CDG的方案设计和实施，注入和产出动态监测及效果分析。
The AdonRoad oilfield is fractured sandstone with a high oil temperature (79.4 ° C) and a large variation coefficient of permeability (0.70). A deep colloidal dispersion gel (CDG) technique was performed early in the waterflood. A total of 564948bbl (8.03% PV) of CDG solution was injected within 20 months with an average polymer concentration of 268mg / L. Within the next 17 months, 556,800 bbl (7.91% PV) of the uncrosslinked polymer solution was injected with an average polymer concentration of 150 mg / L. Implementation effect is very obvious, oil production increased, the amount of water treatment decreased after injection of 32.3% PV, the recovery rate of 45.2% STBOOIP. However, under the same conditions of water flooding, the recovery rate can reach 27% of the STBOOOP, and the cost of chemicals per additional barrel of crude oil is 0.72 U.S. dollars. The actual effect is obviously better than that predicted by the plan. This article discusses in detail CDG’s program design and implementation, injection and output dynamic monitoring and effectiveness analysis.
