Development of petroleum proppant industry

Release time: 2022-12-21

In recent years, with the development of domestic oil fracturing proppant production, the export volume of oil fracturing proppant products has gradually grown from scratch, from less to more. However, overall, exports are still smaller than imports. Moreover, the products are mainly concentrated in the middle and low end products with low added value, while the imported products are high-end products with high added value, such as high-strength oil fracturing proppant products with excellent performance. The development of China's oil fracturing proppant industry is not fast. The average annual growth rate of market size is about 15%, and the average annual growth rate of total production capacity is about 12%. There are a large number of enterprises, but most of them are small enterprises with low output and low technology content. The means of competition are mainly focused on product prices, and there are no super large enterprises that occupy a large market share.

The domestic oil demand continues to increase, and the dependence on foreign oil continues to increase. In order to meet the increasing domestic demand for oil, the oil exploitation industry has developed rapidly. Corresponding to this is the rapid expansion of the production of related products. China's oil fracturing proppant industry has developed rapidly during this period, with the market scale increasing by 20%.

In 2009, the investment amount of domestic oil fracturing proppant industry was 470 million yuan, which increased to 620 million yuan in 2011, with an average annual growth rate of more than 13%.

Research status and progress of functional fracturing proppant used in oil and gas development (I)

When oil and gas are exploited in deep wells, after fracturing treatment of high closing pressure and low permeability deposits, the oil and gas bearing strata will split, and oil and gas will flow out of the channel formed by the fractures. At this time, fluid needs to be injected into the rock base to exceed the pressure of the formation fracture strength, so that the surrounding rock layer around the wellbore will produce fractures, forming a channel with high flow capacity. In order to keep the fractures formed after fracturing open, oil and gas products can pass through smoothly. With the high pressure solution, the oil proppant is used to enter the formation and fill in the rock fractures, which plays a role in supporting the fractures not to be closed due to stress release, thus maintaining high conductivity, making oil and gas unblocked and increasing production.
