    摘要: A circular saw includes a housing, a motor having a rotating axis and a center of gravity on the rotating axis, a handle, a circular blade, a fixed guard, and a base plate having a width supporting the housing. The motor and the circular blade are parallel or coplanar with respect to each other and the circular saw does not extend beyond the width of the base plate in the width direction.

    摘要: Anti-channeling pack-off particles used in a production section of an oil-gas well, a completion method, and a production method are provided. The anti-channeling pack-off particles are macromolecule polymer particles having an average particle diameter of 0.05-1.0 mm and a real density of 0.8-1.4 g/cm3. The particles are compactly filled into a space of the oil-gas well, which is required to be filled and packed off so that there is no channeling path after filling, thus effectively pack-off or sectioning the oil-gas well into multiple, relatively independent regions for production from the oil-gas well, and thus improving the production efficiency of the oil-gas well. Even if a channeling path occurs, a very small flow of channeling fluid of a carrier medium will move some of the anti-channeling pack-off particles in a direction towards the channeling path and accumulate those particles until the channeling path is filled, thereby achieving favorable effects of anti-channeling, packing-off, and sectional flow control.
