Oil & Gas
Oil&Gas(Oilfield chemicals refer to the chemicalsused in oilfield drilling, completion, oil production,water injection, enhanced oil recovery, andgathering and transportation processes. Oilfieldwastewater comes from processes such as drilling,oil extraction, and well washing during oil and gasextraction. Therefore, the composition of oilfieldwastewater is complex, consisting of organic andinorganic mixtures, and also involves thedistribution of organic matter in the water and oilphases. After steam thermal recovery, tertiary oilrecovery, and other treatment processes, theasphaltene, fatty acid substances, thiols, and similarsubstances in the oil enter the water phase in acertain form under certain conditions, Causingsignificant changes in the relative composition oforganic matter in water and oil. With our oilfieldchemicals and application expertise, our customersin the oil & gas industry can improve resourceefficiency, increase well productivity and make themost out of existing hydrocarbon resources.
Polymer for drilling fluid
Drilling fluid is also known as drilling mud. Its function include breaking rock, carrying rock cuttings, lubricating and cooling drill bits, balancing formation pressure and protecting well walls. Maintaining good mud performance is an important means to improve drilling speed and ensure drilling safety, while treatment agents are the key to ensuring mud performance. Due to our products’ high viscosity, it has good thickening, flocculation, and rheological conditioning effects in drilling fluids, and can be used as a drilling mud conditioner in oil production. In order to improve the performance of drilling and completion fluids for different systems, Sinoblue has developed a series of agents. The function is to modify the rheological properties of drilling fluid, carry rock cuttings, lubricate drill bits, and improve drilling speed. In addition, it can greatly reduce drilling accidents, reduce equipment wear, prevent blowout and wellbore collapse, and avoid formation damage during the drilling process.

Polymer for CEOR
Polymer flooding technology is an important technical measure to improve oil recovery. It achieves high oil displacement efficiency through dual actions such as macroscopic expansion of wave sweep volume and microscopic oil washing. High molecular polymers have the advantages of good water solubility, good injectability, shear resistance, high salinity resistance, and strong salt resistance, as well as good chemical and biological stability.Our company has developed a series of flooding products for conventional and low permeability reservoirs. At the same time, polymer has selectivity for oil and water, preferentially entering high aquifers, and plays a role in plugging water and increasing oil production by adjusting the water absorption profile in the formation and plugging the large outlet channels. It is an ideal choice for deep profile control and water shutoff.

Polymer for fracturing
Hydraulic fracturing of oil and gas wells utilizes the principle of liquid pressure transmission, using high-pressure equipment on the ground to inject viscous fracturing fluid that is more than the reservoir can absorb into the reservoir. As a result, the wellbore pressure gradually increases, and when the formation fracture pressure exceeds, one or more horizontal or vertical fractures will form in the oil layer. It is an important technical measure for increasing production of oil and gas wells and water injection wells at home and abroad.Fracturing fluid drag reduction and thickening materials have gradually transitioned from guar gum systems to polymer products. Our company has developed and produced a variety of series of products suitable for the fracturing of conventional vertical wells and large-scale large displacement horizontal wells. The product can be widely used in groundwater, river and lake water, flowback fluid, seawater, high salinity water and other water quality.

Oilfield iron ion stabilizer
The main components of oilfield iron ion stabilizer OFC-611 are iron chelating agents and reducing agents. The product is mainly used for acidizing operations in oil and gas wells, and has the function of preventing Ferric precipitation from damaging the formation. During the acidizing process of oil and gas wells, the acid solution will dissolve a certain amount of iron ions from the underground metal pipe string and formation rocks. When the acid solution is gradually consumed and becomes residual acid, a large amount of Ferric will form precipitates when the pH rises to 2-3, blocking the formation pore throat and reducing the effectiveness of acidizing transformation. Iron ion stabilizers can prevent the re precipitation of Fe from three aspects: complexation, reduction, and dispersion.
