Frac proppant particulate product is a ceramic

It can be widely used in frac proppant fracturing deep, high-pressure oil and gas layers. Frac proppant is a granular product with high fracturing intensity, mainly for oilfield downhole support, to increase fracturing proppants production of oil and gas, an environmentally friendly product. This product is the use of high-quality bauxite and other raw materials, sintered ceramic, is a substitute for natural quartz sand, glass beads, metal balls and other low-strength frac proppant, to increase production of oil and gas have good results. When oil and gas exploration in deep, high ceramic proppants pressure low permeability deposits closed after fracturing treatment, the rock cracked petroleum, oil and gas channel formed from the cracks in the collection out. Ceramic support material along with high-pressure solution into the formation filling in cracks in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high density ceramic conductivity, so that oil and gas flow, increase production. Practice has proved that the use of frac proppant fracturing wells can increase yields by 30-50%, but also to extend the service life of oil and gas wells. By the China Research Institute of Petroleum Exploration and Development Langfang Branch support evaluation laboratory testing.

Hydraulic fracturing is widely used in oil and gas well stimulation prospects

Hydraulic fracturing is the use of ground pressure pump, squeeze with higher viscosity fracturing fluid to the reservoir through the wellbore. When hydraulic fracturing fluid injection rate exceeds the absorption capacity of the reservoir, a high pressure is formed at the bottom of the oil fracturing proppant reservoir, when such pressure exceeds the fracture pressure near the bottom of reservoir rock and the oil will be pressed open cracks. At this time, continue to keep the oil squeeze hydraulic fracturing fluid reservoir internal cracks will continue to expand. In order to maintain pressure to open cracks in the open state, and then to squeeze into the sand-carrying fluid reservoir with proppant (usually quartz sand), followed by sand-carrying fluid Hydraulic Fracturing Proppants into the cracks, one can make the cracks continue to extend forward, on the other hand You can support has been pressure to open the cracks, it Buzhi Yu closed. Then again injected into the displacement fluid, the wellbore fluid carrying sand into the cracks of all replacement with quartz sand to prop up the cracks. Finally, the high viscosity hydraulic fracturing fluid injected degradation automatically discharged outside the wellbore, leaving the reservoir in one or more of length, width, ranging from a high of cracks, so that establish a new path between the fluid reservoir and the wellbore. After fracturing, oil and gas wells generally yield substantial growth.Filled high crush proppants with proppant and support these cracks, when the fracturing fluid reflux proppant will remain to form a channel in these gaps, so oil and gas can flow in the well. Hydraulic fracturing is a broad prospect of oil and gas well stimulation, hydraulic fracturing method is the main form of exploitation of natural gas, requires the incorporation of chemical substances with plenty of water poured into the hydraulically fracture shale to release natural gas.

Fracturing proppant basic information and classification

Fracturing proppant is a granular product with high fracturing intensity, mainly for oilfield downhole support, to increase production of oil and gas, an environmentally friendly product. This product is the use of high-quality bauxite and other raw materials, sintered ceramic, is a substitute for natural quartz sand, glass beads, metal balls and other fracturing proppant fracturing proppant, to increase production of oil and gas have good results. When oil and gas exploration in deep, high pressure low permeability deposits closed after fracturing treatment, the rock cracked petroleum, oil and gas channel formed from the cracks in the collection out. Fracturing proppant material along with high-pressure hydraulic fracturing proppant solution into the formation filling in cracks in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high conductivity, so that oil fracturing proppant and gas flow, increase production. Practice has proved that the use of fracturing proppant fracturing wells can increase yields by 30-50%, but also to extend the service life of oil and gas wells. The product has a high compressive strength, low density, good sphericity, finish high conductivity and strong advantages.
