Produced after
Hydraulic fracturing proppant reflux can cause serious production problems, increased security risks and greatly reduced cost. For this problem, the Dagang Oilfield downhole drilling hospital research studies that may have been fully completed consolidation proppant indoor studies, the product has come out with good performance.
Prevent backflow of proppant There are many ways in which the resin-coated proppant is a more common approach. The proppant in a foreign country in the late 1970s, and was successfully put into application, received extensive attention, after decades of development, has reached a higher level. Domestic control proppant backflow in its infancy, Dagang drilling hospital aim at the world forefront of technology, can begin developing pre-mixed, safe storage, simplifying the construction process and the good performance and compatibility with the fracturing fluid can be consolidated proppant.
Developed by the drilling hospital
Proppant proppant and general appearance is no different, to meet all common proppant performance requirements. It is the common difference between the proppant, it can maintain high temperatures in the formation conductivity in the case of consolidation together, sealing the seam to prevent proppant reflux. Compared with common proppant, the
ceramic proppant has the following properties: ① has a better crush resistance, corrosion resistance, wherein the etching rate of only tenths of a percentage point; ② cured fracturing fluid environment of high flow resistance properties of proppants up to 11 cm / sec; ③ closure pressure of 50 MPa, may consolidation proppant conductivity of 117 square microns · cm.
The successful application of the product will reduce the sand buried reservoir and pump stuck and other production problems and improve the fracturing effect, extend the validity of fracturing operations, reduce security risks, the effective protection of the reservoir.
Shale gas is mined from shale in natural gas, is an important unconventional gas resources. Compared to more conventional natural gas, shale gas development has a long life and exploitation of the advantages of long production cycle, most of the shale gas production and wide distribution, thickness, and generally containing gas, which makes shale gas wells to a stable long-term rate of gas production.
