Analysis of ceramic proppant industry and export status

According to Chinese customs statistics, from 2005 to 2007 of ceramic proppant exports continued to grow in recent years, the export situation is good and fast development of the product, is China's ceramic proppant main reason for the rapid growth of exports. The second half of 2008, continuing the international economic downturn, many export-oriented manufacturers have ceramic proppant into the domestic market, in 2008 the export volume of ceramic proppant only 32,900 tons, down 9.4% ; exports of $ 6.315 million, down 15.6%. Into 2009, with the further support of monetary policy around the world, there are signs of the global economy, coupled with the favorable factors brought about by China's domestic financial policies, the 2009 ceramic lightweight proppant export volume of China rebounded.
Japan, Russia and Southeast Asia is our ceramic proppant main export countries and regions, as China occupies an absolute cost advantage, so the products are currently exported to many countries and regions, the current market share in terms of product Overseas markets still much to do.
Look at China's imports, due to our ceramic proppant, the low intensity of products, and the high strength of the product in the past for a long period of time mainly depends on imported products. With our high-strength ceramic proppant production technology successfully developed and industrialized application, breaking the monopoly of foreign products in this category, imports of ceramic proppant products began to fall, but also by the domestic economy in 2008 the impact of slower growth in domestic demand is relatively relaxed than in previous years, this is the 2008 decrease in imports of ceramic proppant of the main reasons. 2008 imports of ceramic ultralight weight for 8765.2 tons, down 2.5%; imports amounted to $ 4,383,000, a decrease of 10.8% with hoot. Into 2009, China's economic embarrassment by the state policy of stimulating domestic demand eased, the market is increasingly active, supporting domestic demand in the high-end ceramic products increased in 2009, China's imports of ceramic proppant reach 9273 tons, while the amount of imports is reach nearly $ 4.65 million. Italy, Japan and the United States is imported ceramic proppant of major countries and regions

Oil and gas well sand production is one of the important problems facing the loose sandstone reservoir

Oil and gas well sand production is one of the important problems facing the loose sandstone reservoir. The harm of sand production is mainly manifested in the following four aspects:
Oil and gas well production or shut down
Oil and gas well sand production, easy to cause sand buried reservoir, sand plug tubing and manifold and storage tanks in the sand, which was forced to shut down operations. Rinse the sand buried reservoir, sand plug removal of tubing, both time-consuming and expensive, hydraulic fracturing benifits can't completely solve problem. To resume production soon and need to work, live, shorter production cycle and make the oil and gas production, homework cost huge increase, serious economic loss.
The ground and underground equipment and pipeline abrasion
Hydrocarbon flow carried in the formation of sand main composition is sio2, the hardness is very high, is a destructive ceramic proppant suppliers abrasive, can make the pump seat wear and no seal, valve ball pitting, rod and pump cylinder strain, ground valve failure, serious erosion, oil transfer pump impeller thus forced to shut-in homework, replace or repair the equipment, cause the loss of production, the cost is rising.
Casing damage to oil and gas Wells scrap
Serious sand production for a long time in outside casing a huge hole, inner and outer force imbalance lead to sudden formation collapse, cause casing deformation, light weight, casing was wrong fault collapsing, lead to oil and gas Wells of scrapped.
Destroy the formation of the original structure or cause the formation permeability near wellbore area of serious decline
Oil and gas well after the sand, sand migration, formation sand near wellbore area of sedimentation is more, far wellbore area becomes loose structure. Caused a significant reduction in the formation permeability near wellbore area, oil and gas well production decline.
Solve the problem of oil and gas Wells sand production, must be based on the early prevention and control, to reduce the damage to the reservoir cementing
