The polymer dispersing and dissolving device is the key surface equipment used for tertiary recovery, which is mainly applied to achieve the objective of plugging and displacement of oil and increasing the recovery of oil reservoirs by mixing the stock solution of polymer to the design-required density and viscosity through post-treatment such as agitating and maturation after mixing the water with dry powder of water-soluble polymer as per required ratio and dissolving completely.

For the purpose of adapting to the needs of developing the tertiary recovery of Oilfield, the Center started developing the polymer dispersing and dissolving device in 1994. During development, the Center made innovative designs by widely absorbing the advanced technology applied to foreign and domestic similar products, and produced the first polymer dispersing and dissolving device and the matching electric automation control system in 1996 on our own through constant improvement, which was applied to Gudao Oil Production Plant of Shengli Petroleum Administration and was popularized gradually due to excellent application effect. In 1999, the Center was granted with First Prize of Scientific Technology Progress by Shengli Petroleum Administration.

During popularization of the products, the Center has been making constant improvement by perfecting and optimizing the design according to the user’s requirements and field application. As a result, the comprehensive performance of the product is in a leading position in the foreign and domestic similar device and presently a series of products have been developed, including mixing capacities of 20m³/h, 30m³/h, 50m³/h, 60m³/h, 80 m³/h and 100m³/h. Furthermore, dozens of such device have been applied at site. In addition, the Center is capable of designing and producing custom-made products in accordance with the user’s special requirements.
