胶态分散凝胶深部调驱技术在辽河油田的应用

Application of Colloidal Dispersion Gels in Deep Profile Control and Displacement of Liaohe Oilfield

普通调剖措施对高渗透率油藏调剖效果不明显,主要表现为"注入剂量低、有效期短、增产幅度小"。通过对聚丙烯酰胺/柠檬酸铝胶态分散凝胶深部调驱堵水技术的室内研究,重点做了胶态分散凝胶与高升油田污水配伍性实验,并应用于矿场试验。在试验期间试验井组产油上升,含水下降,油层吸水状况得到有效改善,增产效果明显,经济效益显著。

Normal profile control for high-permeability reservoir has not obvious effect,mainly appearing as ＂low injected dose,short period of validity,small production increase＂.Based on the indoor study of deep profile control and flooding water shutoff technology of polyacrylamide/aluminum citrate colloidal dispersion gels,the compatibility experiment of colloidal dispersion gels and Gaosheng oilfield sewage was conducted and applied in field experiment.During the trial,the oil production of test well group was increased,water content cut down,reservoir water absorption condition was improved,leading to obvious production increase and significant economic benefit.
