Since 1903, cementing technology at home and abroad has made great progress after 100 years effort. Oil cement type extends from one to thirteen, and oil cement additives begin to be used and product technology improves. The abroad additives have increase to 14 kinds and more than 200 varieties. Cementing equipments become automatic operation, precision density control and large energy and high power. Complex strata cementing technology become completed and develop cementing supporting technology which can adapt to the high pressure gas well, plastic strata, low voltage and easy-to-leak well, many pressure system, deep wells, super deep well etc.
