防止抽油机井结蜡的新方法在抽油机井中，可采用不同的方法控制结蜡。以小剂量向井内添加某种化学剂是普遍采用的方法，因为这种方法能够降低原油粘度并减少管柱内结蜡。这种化学剂叫做降粘剂，在室温下呈半固态。利用计量泵和储罐，通过细管线向套管内连续泵入稀释的化学... New Ways to Prevent Waxing of Sucker Rods Waxing can be controlled in different ways in pumping wells. Adding a chemical to the well at low doses is a commonly used method because it reduces the viscosity of the crude oil and reduces wax formation in the column. This chemical is called a viscosity reducer and is semi-solid at room temperature. Using metering pumps and tanks, continuously pump diluted chemical through thin tubing into the casing ...
