塔河油田稠油井在掺稀开采过程中常常出现井筒堵塞的情况，严重影响正常生产。堵塞物的四组分分析结果表明，其主要成分为沥青质，所占质量分数达57％。考察了不同类型化合物对堵塞物的溶解性能，并考察了助剂的复配效果，研制了复合解堵抑堵剂 RPDA-02，该剂对堵塞物的饱和溶解量达2.0 g？g，显著优于现场使用的对比剂。考察了 RPDA-02的抑堵效果，结果表明，该剂对沥青质沉积的抑制时间超过60天。研究了现场工况条件对该剂解堵抑堵性能的影响，结果表明，使用温度变化对其性能影响很小。开发了掺稀连续加剂工艺，可较好地解决稠油井堵塞问题，并对采出液的后续处理无不利影响。

Heavy oil well blockage occurs frequently in dilution exploration process in Tahe oilfield, which influences the production seriously.The SARA analysis of the blockage indicates that about 5 7%of it is asphaltene.This work investigates,based on the analysis,the solubility properties of the plug in different mediums and develops a new composite blockage removing and inhibiting agent RPDA-02.Its saturation solubility for the blockage is up to 2.0 g?g,much higher than the reference agents. The blockage inhibition performance of RPDA-02 shows that the inhibition time for asphaltene deposition is more than 60 days.The field test shows that temperature changes have little impact on the performance of RPDA-02.A continuous agent injection process is developed based on the conditions of the oilfield, which can well solve the problem of blocking and has no undesired effect on the subsequent processing of produced liquid.
