Inorganicscale which forms in the process of oil field development results in industrial accidents, decreasing economic benefits as well as hinding production.
油田开发中产生无机垢不仅阻碍油气生产，降低经济效益，还可能造成生产事故。

The results show inorganicscale is calcium carbonate and scale in down hole and well bore area is the most severe. It agrees with practical situation basically.
结果表明，油井无机结垢类型主要是碳酸钙垢，结垢最严重区域为油井井底及近井带，与实际情况基本吻合。

High anti-scale efficiency. The maximum allowable value of LSI index in original water is 2.8, and it can control inorganic scales effectively within this range.
