What does oil fracturing sand mean?

Petroleum fracturing sand, referred to as "fracturing sand" for short, is a method of injecting high-pressure liquid into wellhead to fracture natural resource reservoirs such as oil, and then injecting sand particles with a certain size to make them permanently fracture without plugging the fractures, and make them form natural resources such as oil and water to flow circularly. Its principle is to use artificial external force to break the originally closed rock stratum, thus improving the oil and gas recovery rate.

Oil fracturing sand control technology is widely used in the exploration and development of natural resources such as oil, natural gas and coalbed methane. Its advantages are high oil recovery, high efficiency and energy saving, and less environmental pollution. According to statistics, oil fracturing sand adding technology has been widely used in many countries and regions around the world, and great progress has been made.

Although the technology of oil fracturing and sand addition has many application prospects, there are also some disputes and risks. First of all, the exploitation cost of oil fracturing sand adding technology is too high, which will bring great economic pressure. Secondly, the environmental problems caused by oil fracturing sand are also the focus of public attention, destroying groundwater resources and causing seismic source and noise pollution. Therefore, the application of oil fracturing sand control technology must be based on scientific and technological achievements and risk assessment, and strengthen self-restraint and supervision.
