Characteristics of ceramic proppant products

After fracturing oil and gas wells chinese proppant in its stimulation effect and production performance depends conductivity cracks. Fracture conductivity fracture conductivity is within the reservoir fluids, fracturing proppant and fracture permeability Aperture product support to represent. Therefore, physical properties and distribution of ceramic proppant in the fracture is an important factor china proppant affecting fracture conductivity. Of ceramic proppant performance requirements are as follows:

1, ceramic proppant have sufficient compressive strength and resistance to abrasion, resistant to strong pressure and friction during injection, and effectively support the artificial cracks.

2, ceramic proppant particles relative density is lower, easy to pump into the underground.

  3, ceramic proppant particle sizes to meet the design requirements of different wells, typically 0.4-0.8mm, roundness and sphericity greater than 0.9, and particle uniformity, smooth surface, turbidity should be less than 1000, in order to obtain the best possible high conductivity.

  4, ceramic proppant particles at a temperature of 200 ℃ conditions, the fracturing fluid and reservoir fluid chemical reaction does not occur, the acid solubility of the maximum allowable value should be less than 7%.

Basic Features ceramic proppant industry

Ceramic proppant ceramic proppant particles is a product with high fracture strength, mainly used in oil well supported, to increase production of oil and gas, an environmentally friendly product. Ceramic proppant is the use of high-quality sintered bauxite and other raw materials, is a substitute for natural quartz sand, glass beads, metal balls and other low-strength proppants to increase oil and gas has a positive effect. When oil and gas exploration in deep, high pressure low permeability deposit closure after fracturing treatment, the hydrocarbon-bearing formation split, passage of oil and gas from the cracks formed in the collection out. Ceramic proppant material along with high-pressure solution is filled into the formation in rock fissures, cracks do not play a supporting closed due to stress lightweight proppant release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production. Practice has proved that the use of ceramic proppant fracturing wells can increase production from 30 to 50%, but also to extend the service life of oil and gas wells.

Ceramic proppant industry analysis

Ceramic proppant oil,fracturing proppant a key material in low permeability gas exploration fracturing oil and gas wells, in a good macroeconomic policy, ceramic proppant products in the future exploration and development of oil and gas wells in the application will be more widely used , in line with national industrial policy. Accelerate local economic development, through the development of energy, increase investment, develop new application of technology, led a complete industrial chain of circular economy and building a harmonious society has become the primary task of the various local governments. Ceramic proppant has played an important role in the application of oil and gas wells, not only to increase oil and gas production,China proppant and can extend the service life of oil and gas wells. Therefore, research and development of ceramic proppant technology, practical point of view, there is a very good market space, in line with the relevant policies of local governments.

Uses proppant

Proppant fracturing ceramic proppant can be used in deep, high-pressure oil and gas layers. High-quality bauxite as the main raw material crushed to a fine powder after fine grinding, together with various additives, repeated kneading, granulation, polishing. High temperature sintering, the product has high strength, low density, good ball, finish high, strong conductivity and so on. By the China Research Institute of Petroleum Exploration and Development,isp proppant Langfang Branch support evaluation laboratory testing, the performance indicators fully meet SY / T5108-2006, SY / T6302-1997 standard, currently in the lead.

Developments in the oil proppant

In recent years, proppant plant with the development of the domestic production of oil fracturing proppant, proppant fracturing of oil product export volume gradually from scratch, from less to more. However, overall, the export volume is still less than imports. And products are mainly concentrated on low value-added low-end products, imports are high value-added high-end products, such as the excellent performance of high strength proppant fracturing of oil products. Development of oil fracturing proppant industry is not fast, the market size of the average annual growth rate of about 15 percent, the average annual growth rate of the enterprise total capacity of around 12%. Large number of enterprises, but most are small businesses, low yield, low-tech, competition means also focused on product prices above, and do not occupy a larger share of the market, especially large-scale enterprise production. Domestic oil demand continues to increase dependence on foreign oil continues to increase. In order to meet the increasing domestic demand for oil,petroleum proppant the oil industry has developed rapidly. Correspondingly related products is rapidly expanding. China's oil fracturing proppant industry at this time, the relatively rapid development, the market scale growth rate reached 20%. In 2009, Chinese oil fracturing proppant industry investment of 470 million yuan, in 2011 increased to 620 million yuan, an average annual growth rate of over 13%.
