The importance and application of scale and corrosion inhibitors in oilfield development are summarized. The scale and corrosion problems that may occur in oilfield production are summarized. Type and composition of scale and corrosion inhibitor: 1. Organic scale and corrosion…
This paper discusses the research and application of scale inhibitor in oilfield, analyzes the importance of scale inhibitor in oilfield development and its working principle. Through literature review and practical cases, this paper focuses on the different types, components, working…
Drilling fluid is a chemical agent that plays an important role in the process of oil and gas exploration and production. Drilling fluid, also known as drilling mud, is a special liquid used in the drilling process, mainly composed of…
In the petrochemical industry, hydrocracking is an important process used to convert heavy petroleum distillates into light, high-value products. Hydrocracking scale inhibitor is a chemical additive used to prevent hydrogen from forming a scale layer during hydrocracking. The main purpose…
Reverse demulsifier can effectively improve the interfacial tension of oil-in-water (W/O) or oil-in-water (O/W) emulsion, so that the colloidal particles in the sewage lose their stable repulsion and attraction, and eventually lose their stability and form floc, and further through…
On July 26, 2021, China National Petroleum Corporation (CNPC) announced that its Daqing oilfield in northern China has successfully achieved an annual production of more than 50 million tons of oil. This marks the 33rd consecutive year that Daqing Oil…
Introduction: During oil field production, the mixture of gases and liquids often forms foam, which can affect production efficiency and operational stability. To solve this problem, oil field defoamer is widely used as a chemical additive designed to reduce the…
Introduction: Oilfield acidification is an important method to increase productivity, but it also comes with the risk of corrosion. In order to solve this problem, acidizing corrosion inhibitor, as a key chemical additive, is widely used in oilfield production. Acidizing…
Point depressant refers to the chemical that can reduce the freezing point of lubricating oil, generally polymer organic compounds, many varieties and oil and gas use point depressant. The commonly used varieties of lubricating oil are alkyl naphthalene, polymethacrylate, polya-olefin…
Oil field water corrosion inhibitor can be used to delay the corrosion of oil field water to metal, so what is its principle of action? They are complex dissolution, lattice distortion, electrostatic repulsion and so on. When we choose it,…
