Resin coated ceramic proppant better than traditional proppant

From the mid-1970s, various countries started to develop, the use of resin coated ceramic proppant. As such the proppant to overcome the inherent shortcomings of traditional sand and ceramic proppant , not only to prevent the proppant is crushed and spit phenomenon. Also it reduces the proppant embedment formations ills. In addition, the use of such proppant can prevent fines migration, and therefore at higher fracture closure stress also enables to maintain good long-term permeability. Many fields have been widely used in lieu of such proppant sand and ceramic. Examples illustrate it in hydraulic fracking effect day job better than conventional proppant, oil yield significant role through laboratory evaluation and field. Economic analysis shows that it is before a most economical and reasonable great development of the new force hydraulic fracturing proppant.

Shale gas revolution

As society growing demand for clean energy, natural gas prices are rising, people's awareness of the rapid increase in shale gas. In particular, the level of horizontal drilling and fracturing technology continues to progress, the human exploration and development of shale gas boom is being formed.Shale gas revolution has shaken the world LNG market structure, and this effect will become more significant, thereby changing the pattern of world energy. Development of shale gas, especially shale gas production increased dramatically, making this the majority of people still 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 driven strategic growth opportunities, as a catalyst for world oil and gas geopolitical situation has undergone structural adjustment
         

Ceramic proppant more and more widely used in oil and gas fields.

Proppants currently used mainly in quartz sand, bauxite ceramic sand and resin-coated composite particles. Due to the low cost quartz sand, while low density easy pumping, is widely used, but quartz sand strong low end, the ball is poor, reducing fracture conductivity, does not apply to closed high pressure deep well. Composite resin coated frac sand particles, the sphericity improved corrosion resistance strong, conductivity is also good, but the products remain short-term, the cost is too high, the cost-oriented promotion is not easy today, while the use of bauxite ceramic proppant ceramic technology, high density, good sphericity, corrosion resistance, high temperature, high pressure, while the costs can be better controlled, and therefore more and more widely used in oil and gas fields. Practice has proved that the use of ceramic proppant fracturing of oil wells can increase production by 30-50%, but also to extend the service life of oil and gas wells, a key material in the oil and gas wells in low permeability oil and gas extraction, construction, not only to increase oil and gas production, and can extend the service life of oil and gas wells.

Hydraulic fracking technology widely used in shale gas development drilling

Hydraulic fracking technology is one of the core technology of shale gas development, widely used in shale gas development drilling.Well drilling in shale gas well production, long production time, shale gas development is the most reasonable way, horizontal well location should try to choose natural fracture system development, organic enrichment, low Poisson's ratio and Young's modulus high places.
There are low-pressure horizontal drilling underbalanced drilling, and rotary steerable drilling control pressure drilling technology, low pressure air underbalanced drilling technology is more mature, controlled pressure drilling technology can be a good problem to overcome borehole collapse, rotary steerable drilling technology is shale gas horizontal drilling technology development. Horizontal drilling combined with reasonable measures to increase production is a necessary means of shale gas production increase.

Fracturing proppant relative density is lower

Fracturing proppant into the formation along with high-pressure solution filled in the cracks in the rock, play a supporting fissure is closed not because of stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production.
Petroleum proppant performance requirements:
 1,proppant have sufficient compressive strength and wear resistance, can withstand strong pressure and friction during injection and effectively support the artificial cracks.
 2, proppant particles relative density is lower, easy pumped underground.
 3, proppant particles under conditions of a temperature of 200 degrees, with the fracturing fluid and the reservoir fluid is not a chemical effect, the acid solubility of the maximum permissible value should be less than 7%.
