The method finishes the well cementation operation by connecting the circulating head in the well mouth area, finishes the 20" surface layer sleeve well cementation operation without occupying well mouth time, finishes the all-well-section sealing by returning cement to the well mouth according to high-temperature and high-pressure shaft completeness requirements, and guarantees the integration of the 20" sleeve and a 30" pile pipe to realize the shaft completeness.

The invention provides a kind of fermented milk and its preparation method which can increase the drinking physical examination and reduce wall-hanging. The preparation method of the fermented milk comprises the following steps: degassing, homogenizing, sterilizing, and cooling the raw materials; then adding a starter, fermenting at 41-43°C for 2-3 hours, cooling to 32-37°C, and continuing Ferment until the acidity reaches 75°T, then stop the fermentation; after the fermentation feed liquid is demulsified, use a high-frequency rotor pump to beat the demulsified feed liquid through the cold plate to the tank to be filled; then beat it to the filling machine through the screw pump After filling, the finished product is obtained; after being refrigerated and cooked, the finished product leaves the factory. Using the preparation method of the present invention to produce fermented milk, the best drinking experience of the product can be obtained without reducing the product index and without increasing the dilution step. At the same time, the present invention adopts the secondary fermentation process in the fermentation process to ensure the shelf life of the product stability.

The invention discloses a method for continuous production of 1-hexene and 1-octene, comprising: (1) after mixing a solvent and an alkyl aluminum compound in a mixing tank, they are continuously introduced into a reaction kettle, and ethylene is introduced into the reaction kettle. Under the effect of the catalyzer that feeds, ethylene oligomerization reaction occurs, obtains the reaction solution containing 1-hexene and 1-octene; (2) the reaction solution containing 1-hexene and 1-octene enters through overflow line to the overflow tank reactor; (3) the reaction solution obtained by the overflow tank reactor enters the quenching reactor, and uses alcohols as a quenching agent to quench the reaction to obtain 1-hexene and 1-octene. Wherein, the catalyst used is a solution formed by a metal chromium compound, a PNSiNP ligand and an organic boron compound. In the invention, without changing the reaction temperature, the overflow tank adopts a higher temperature, and the polymer from the reaction kettle can be dissolved in the reaction liquid, thereby reducing the possibility of pipeline blockage and improving the continuous operation time of the device.
