The invention relates to a production increase method for a deep layer shale gas reservoir. The production increase method comprises the following steps that (1) compressibility and ground stress evaluation is conducted on a stratum; (2) cluster perforation parameters are determined, and the perforation mode is circumferential perforation; (3) after crake parameters and construction parameters are determined, fracturing is conducted on target stratum shale; (4) pre-acid-fracturing treatment is conducted, and acid fracturing adopting high mucic acid and closed acidizing treatment adopting low mucic acid are included; (5) slickwater containing a propping agent is injected, and the sand-to-liquid ratio is gradually increased to be 20% from 1%; and (6) high viscosity glue liquid containing a propping agent is injected, and the sand-to-liquid ratio is gradually increased to be 23% from 5%. A deep layer shale gas well is transformed by using the production increase method, and the productive potential of the deep layer shale gas reservoir can be increased.

The present invention provides a method of synthesizing an ester of a saturated carboxylic acid from a saturated polyhydroxycarboxylic acid by performing a deoxydehydration reaction and a hydrogen transfer reaction.

The invention discloses a method of promoting colonization of delftia tsuruhatensis at plant rhizospheres, and provides application of mucic acid in the aspects of promoting colonization of delftia tsuruhatensis at the plant rhizospheres and preparing preparations for promoting colonization of delftia tsuruhatensis at the plant rhizospheres. By adopting the method, a signal molecule, namely mucicacid capable of promoting colonization of delftia tsuruhatensis at the plant rhizospheres is screened out from secretions of plant root systems, research shows that mucic acid has significant chemotactic and swarming effects on delftia tsuruhatensis and can significantly promote colonization of delftia tsuruhatensis at the plant rhizospheres; besides, when mucic acid and delftia tsuruhatensis comeinto play together, reproduction of delftia tsuruhatensis at the plant rhizospheres can be significantly promoted; the total fresh weight, the total root weight, the plant height, the chlorophyll content and the root system nifH gene abundance of plants are significantly increased; a growth-promoting effect on the plants is further improved significantly, and thus the method has excellent application value and broad development space.

The invention belongs to the technology of oil field acid fracturing and water injection for recovery rate enhancement. A physical solute of reducing viscosity and resistance PSR has the general principles: the PSR is prepared through optimization of a profile control agent PCA, a polymer physical solute PPS and a rock physical solute RPS, and profile control, the polymer viscosity reduction rate and the displacement resistance-reducing rate are the maximum. The PSR has the characteristics of no oxidizing agent, safety, environmental friendliness, no toxicity, neutral property, no corrosion, no flammable or explosive materials, low molecules, no harm, no impurities, low friction resistance, and no deterioration; the corrosion inhibition rate and the retardance rate of organic acids and inorganic acids are greatly improved, and the acidification is fully effective; the dissolved polymer chain-breaking viscosity-reducing rate is high; fillings and cements in rock pore seams are dissolved, nano pore seams are opened and expanded, and the resistance reduction rate is high; the profile control is good, and the injection pressure is not increased but falls. The PSR is used for high permeability, ultra-low permeability oilfield profile control, polymer viscosity reduction, acid fracturing, water injection and oil driving, improves the polymer depolymerization viscosity reduction rate, improves the displacement resistance-reducing rate, improves the ultralow-permeability rock permeability rate, and increases reservoir, injection and yield.
