1. Polymer for tertiary oil recovery (EOR).

The company can customize different types of polymers according to different location conditions (ground temperature, salinity, permeability, oil viscosity) and other indicators of each block of the oilfield, so as to effectively improve oil recovery rate and reduce water content. Common models are as follows:

Product name	Electric density	Molecular weight	Application
7226	Middle	High	Medium low salinity, medium low geotemperature
60415	Low	High	Medium salinity, medium geotemperature
61305	Very low	High	High salinity, high geotemperature

2. High efficiency drag reducer for fracturing

Efficient drag reducing agent for fracturing, widely used in fracturing drag reduction and sand carrying in shale oil and gas production.

Has the following characteristics:

i) Ready to use, has high drag reduction and sand carrying performance, easy to return

ii) There are different models suitable for the preparation of fresh water and salt water.

Product name	Electric density	Molecular weight	Application
7196	Middle	High	Clean water and low brine
7226	Middle	High	Low to medium brine
40415	Low	High	Medium brine
41305	Very low	High	High brine

3. Profile Control and Water Plugging Agent

According to different geological conditions and pore size and molecular weight, the profile control water blocking agent can be selected between 500,000 and 20 million, which can realize three different ways of delaying cross-linking, pre-crosslinking and secondary cross-linking.

Product name	Electric density	Molecular weight
5011	Very low	Extreme low
7052	Middle	Medium
7226	Middle	High

4. Drilling Fluid Wrapping Agent

Adding drilling fluid coating agent to drilling fluid can effectively control the apparent viscosity, plastic viscosity and filtration loss. It can effectively cover the cuttings and prevent the cuttings mud from hydration, which is beneficial to the stability of the well wall, and also has the ability to resist high temperature and salt.

Product name	Electric density	Molecular weight
6056	Middle	Middle low
7166	Middle	High
40415	Low	High
