| titleOfInvention | The molten hydraulic cementing materials of high temperature resistant theobromine and be used for oil-well cement slurry system |
| abstract | The invention discloses the molten hydraulic cementing materials of high temperature resistant theobromine and it is used for oil-well cement slurry system, the hydraulic cementing materials is made of by weight following each component: 100 parts of lime stone, 10~15 parts of clay, 2~4 parts of bloodstone, 1~3 part of diatomite, 0.1~2 part of ardealite, 1~2 part of gypsum, 30~35 parts of silicon powder, 0~50 part of Iron Ore Powder, 30~45 parts of calcium carbonate.The oil-well cement slurry system prepared by the hydraulic cementing materials includes: 100 parts of cementitious material, 0~1.5 part of kayexalate, 3~6 parts of 2- acrylamide-2-methyl propane sulfonic, 0.5~0.8 part of 2- acrylamide-2-methyl propane sulfonic acrylic copolymer; 1~1.5 part of butadiene-styrene latex; 0.01~0.5 part of dimethicone, 35~50 parts of water.Present invention process is convenient, low in cost, keeps good sedimentation stability in the hot environment of 80 DEG C~130 DEG C of underground by the physical suspension ability of material granule itself, is expected to be applied to the fields such as oil/gas well reservoir temporarily closes, water blockoff, unconventional gas reservoir are cemented the well. |
