摘要
辽河曙光油田曙三区油井结蜡、出砂严重，油井经常蜡卡。通过使用电加热及化学清防蜡技术，整个区块的清防蜡工作大有改现，取得了较好的经济效益。本文报道两种清防蜡剂的筛选及在曙三区现场应用情况。
Downhole wax deposition is extensive in production wells of District Shuguang Ⅲ in Liaohe. To solve this trouble problem a wax deposite remover in organic solvents, MH-20, and an aqueous waxing inhibitor acting as surface wetting agent, Inhibitor 933, are selected out and the period Inhibitor 933 functionates downhole is determined in several wells by chemical tracer method. Wax removal/waking inhibition operations using MH-20,Inhibitor 933 or MH-20 + 933 in four types of trouble wells by four different technologies are described.
