Frac sand companies produce liquid at temperatures lower

Fired frac sand companies production is most important a process, have a great impact on their microstructure and macroscopic properties. After determining the ratio of the specimen, it will produce a fine powder in the firing process at a lower temperature between the liquid phase, but also to frac sand companies and petrochemical reactions corundum frac proppant crystal form transition occurs, and therefore the firing temperature must be controlled so that maintained within the optimum temperature range to ensure after the firing has excellent frac sand companies overall performance. If the temperature is too high there will be over-burning phenomenon, and ferric oxide (Fc203) of content. After the surface of a liquid phase, the oxygen diffusion to the center fracturing proppants of the block, this time occurs Fe203 = 2Fe0 + I / 20z reactions. Since the volume of the frac sand companies strength and the effect of the density of the reaction products are reduced. If the calcination temperature is too low due to burning phenomenon occurs due to insufficient sintering, its intensity is reduced. Firing temperature has little effect on the bulk density, but has a greater impact on the frac sand companies High crush proppants crushing rate and the acid solubility. Minimum firing temperature corresponding crushing rate of 1360 ℃, while the corresponding acid solubility best when firing temperature is 1350 ℃. Therefore, in order to obtain the desired combination of properties, the firing temperature must be between 1350-1370 ℃; producing a frac sand companies to the firing temperature should be controlled at about 1360 ℃, the solubility of the acid <5%, to meet the Claim.

Ceramic proppant is the key material mined fracturing

Our rich shale gas resources. Recoverable shale gas resources of about 26 trillion cubic meters, the resource potential and the United States is similar, the difference is with the United States, China's shale gas exploration more difficult, much deeper than the depth of the U.S. shale gas reservoirs. Some Russian experts believe that China's shale gas development is still in the "young" stage. Americans also believe that technically the development of shale gas is still in its early stages.

However, China's strong demand for natural gas, driving to accelerate the development of shale gas industry. In 2009, China's natural gas consumption amounted to 81 billion cubic meters, of which domestic production of 76 billion cubic hydraulic fracture stimulation‍ meters, accounting for 94%. 2020, China's natural gas gap will exceed 135 billion cubic meters. Thus, there are plans to actively develop unconventional gas resources to meet our demand for natural gas will be an important way and protection.

In order to accelerate the exploitation of shale gas, the National Development and Reform Commission and the National Energy Board in September 2009 began to study the development of shale gas exploration and encourage the development and utilization policies. National Energy Board to establish shale gas exploration and development of key technology research projects, increase scientific and technological research, breakthroughs in core technologies to accelerate the pace of shale gas exploration and development. Specific shale gas development plans and policies being developed and research.

April 13, 2011, the first well ultra-deep wells kilometers Strategic Survey "National shale gas resource potential evaluation and favorable region preferably" special construction of oil and gas resources from the Ministry of Land and organize the implementation of the Strategic Research Center - Cen Page 1 Well, in Guizhou Province, Yang Xiang smoothly Cengong spud.

developing shale gas revolution: the United States

Shale gas resources in the world for research and exploration and development first began in the United States. Rely on the development of mature production technology and improve network facilities, the U.S. shale gas costs only slightly fracturing proppants‍ more than conventional gas, which makes the United States became the only country in the world to achieve large-scale commercial shale gas exploitation. Data show that in 2010 the U.S. shale gas production has exceeded 100 billion cubic meters. In the past five years, U.S. shale gas production increased more than 20-fold - from 1% in 2006 only for its natural gas production, to growth in 2010 to 20% of U.S. gas production. Experts pointed out, relying on shale gas exploitation in the next 10 years, the United States not only a large-scale imports of natural gas changed the situation, to achieve full self-sufficiency, is also expected to become LNG exporter.

American "shale gas revolution" has shaken the world LNG market structure, and this effect will become more significant, and thus change the world's energy landscape. Thanks to breakthroughs in unconventional gas, especially shale gas development technology, in 2009 the United States with 624 billion cubic meters of production for the first time over Russia became the world's first gas-producing countries. Replacement of ceramic proppants/ceramic ‍ production status of the U.S. long-term dependence on imports of natural gas consumption in the situation reversed. U.S. experts believe the excitement, with shale gas, the United States 100 years no worries.

Development of shale gas, particularly a sharp increase in U.S. shale gas production, the majority of people still make this a very strange energy has become a hot topic. Quietly coming of "shale gas revolution" began to have a significant impact on the global natural gas supply and demand changes and price movements, and cause gas production and consumption country concerned. Exploitation of shale gas, a low-carbon economy Coal seam gas‍ impetus strategic development opportunities, become a catalyst for the world's oil and gas geopolitical situation has undergone structural adjustment.

Shale gas is mined out from shale gas, methane-based ingredients, is an important unconventional gas resources. Formation and enrichment of shale gas has its own unique characteristics, often greater thickness distribution in the basin, widely distributed shale source rock formations. Compared to more conventional natural gas, shale gas reservoirs with self-generated self-storage features, both shale source rocks, reservoirs and is Coal seam gas‍ not subject to structural control, no traps, no clear the air-water interface. Shale gas buried large depth range, depth from 200 m to 3000 m deep at. Most widely shale gas distribution, a large thickness, and generally containing gas, which makes possible to stabilize shale gas production rate of long-term gas, having a long cycle life and long exploitation advantages. [2]

Global shale gas resources are very rich. It is predicted that the world shale gas resources of 456 trillion cubic meters, mainly in North America, Central Asia and China, the Middle East and North Africa, Latin America, the former Soviet Union and other regions. And conventional natural gas equivalent, resin coated ceramic ‍ shale gas resource potential may be greater than conventional natural gas.
