研究了渤南油田高温低渗透砂岩油藏使用的调剖剂,其中包括酸系单液法调剖剂、铁系单液法调剖剂和硅系双液法调剖剂。这些调剖剂均是无机调剖剂,可满足高温油层调剖的需要,而且都是有近井增注远井调剖作用的调剖剂,因此适合于低渗透地层的调剖。在1993~1994年渤南油田五区的区块整体调剖中,使用了所提供的调剖剂,取得了好的效果。
The profile control agent used in the high temperature and low permeability sandstone reservoirs in Bonan Oilfield is studied, including acid-based single-fluid profile control agent, iron-based single-fluid profile control agent and silicon double-fluid profile control agent. These profile control agents are inorganic profile control agent, which can meet the needs of profile control of high-temperature oil layers, and are all profile control agents with near-well injection and far-well profile control. Therefore, they are suitable for profile control of low permeability strata. In 1993 ~ 1994 Bonn Oilfield five blocks of the overall profile, the use of the profile control agent provided, and achieved good results.
