For the purpose of balancing pressure and stabilizing formation,better isolating drilling fluid and slurry,improving replacing ratio,the DG high temperature resistant spacer was developed and used.

The well cementing anti-leak spacer FSG-Ⅱ has been developed in view of formation leak and poor cementation between cement and borehole wall result in poor cement quality and the height of cement return is unable to reach design requirement.

In order to solve the problems in wet mixing cementing spacer operation,including time consuming,and limitation to certain situation the injecting while mixing(IWM) spacer was developed.

Re-search and application of MS-R high-density spacer fluid;

Study on high density flushing spacer fluid;

Spacer fluid density is in 1.

The clinical analysis of fluid sequestration in severe acute pancreatitis;

Objective:To analysis fluid sequestration in severe acute pancreatitis(SAP).

In order to decrease the cost of ocean oil storage and prevent pollution of traditional oil and water replacement,a new idea about underwater oil storage with separate replacement of oil and water was put forward.

In recent years, with the rapid development of materiel plasm transportation equipment, the application of oil isolation pump become more and more widely-used in the different kinds of fields such as mine, power station and petroleum etc.
