| titleOfInvention | A kind of Clean-water-carryingpetroleum petroleum proppant for petroleum production of low-permeability petroleum reservoir and preparation method thereof |
| abstract | The invention provides a kind of Clean-water-carryingpetroleum petroleum proppant for petroleum production of low-permeability petroleum reservoir, this propping agent is obtained after macromolecule resin is coated by 3 ~ 100 object high molecular polymerization composition granules, and described high molecular polymerization composition granule is by the polymkeric substance Archon of polymerizing olefin monomers or the polymer microballoon that is composited after adding silane coupler modified mineral material; The volume density of this propping agent is 0.5 ~ 1.0g/cmn 3 , volume density is 1.1 ~ 1.5g/cmn 3 .The present invention additionally provides the preparation method of this petroleum propping agent simultaneously, and the clear water adopting this preparation method to prepare carries the viscosity that petroleum propping agent can reduce sand-carrying agent greatly, reduces the injury of formation and pump, even can realize clean fracturing.Whole construction cost can be made to reduce with this low-density propping agent, propping agent not easily occur and spues or the emptying phenomenon in crack. |
