Aging treatment method for accurate die-cast cylinder body of auto air-condition compressor
The invention discloses an aging treatment method for an accurate die-cast cylinder body of an auto air-condition compressor. The aging treatment method comprises the following steps of 1 solution hardening, wherein the compressor cylinder body formed through accurate die casting is subjected to solution hardening; 2 natural aging treatment, wherein the hardened compressor cylinder body stands for 2-26 hours at the room temperature; and 3 artificial aging treatment, wherein the compressor cylinder body subjected to natural aging treatment is put into a box type furnace with the temperature ranging from 175 DEG C to 215 DEG C for heat preservation for 3-9 hours. By means of the aging treatment method, the cylinder body is high in hardness, and the work efficiency is high.
Summary In the pilot study, a new geomodeling technology is presented for developing 3D heterogonous geomodels for Athabasca McMurray (MCMR) oil sands. The geomodels were used to simulate SAGD thermal recovery. Both conventional SAGD completions and SAGD with ICD completions were tested. The simulation results show that for a heterogeneous Athabasca McMurray oil sand reservoir, the ICD completion technology enhances oil production and reduces steam consumption. As a result, the economics of SAGD recovery from the heterogeneous sands is improved.
