Well treatment composition crosslinkers and uses thereof

This invention relates to compositions used in treating subterranean formations, which include a hydrated polymer, and a dry blended multi-functional component. The hydrated polymer and dry blended multi-functional component are mixed at the ground surface of a wellsite, and subsequently injected into the formation providing controlled delay in crosslinking to achieve targeted fluid viscosity properties. The hydrated polymer may be a guar, hydroxypropyl guar, carboxymethyl guar, carboxymethylhydroxypropyl guar, synthetic polymers, and guar-containing compounds. The dry blended multi-functional component may include a crosslinker and a chelating agent, and the well treatment fluid may further include an activator mixed with the hydratable polymer. The chelating agent may be a polyols, gluconate, sorbitol, mannitol, carbonate, or any mixtures thereof. The crosslinker may be any source of boron, alkaline earth metal borates, alkali metal borates, zirconium compounds, titanium compounds, or any combination thereof, while the activator may be a caustic soda or magnesium oxide compound. The invention further provides methods for producing a well treatment composition including providing a hydrated polymer, and providing a dry blended multi-functional component. Also, methods of hydraulically fracturing a subterranean formation, as well as cleanup operations and gravel packing a wellbore are provided as well.

High-quality strawberry planting dedicated slow-release compound fertilizer

The invention relates to the compound fertilizer field, and particularly relates to a high-quality strawberry planting dedicated slow-release compound fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of a 1250-2000 mesh diatomite, 4-5 parts of borax, 2-3 parts of ammonium molybdate heptahydrate, 10-12 parts of sodium humate, 20-25 parts of urea, 18-22 parts of potassium nitrate, 25-28 parts of organic compost, 2-4 parts of fish meal, 1-3 parts of sesame leaves, 8-10 parts of alfalfa meal, 15-18 parts of corn distiller grains, 2-4 parts of brine, 8-10 parts of an erythromycin fungi residue, 1-2 parts of an EM microbial agent, 4-6 parts of a fern root residue, 1-3 parts of nano silver, 1-2 parts of a semen ginkgo powder, 4-6 parts of 1,6-hexanediol diacrylate, 10-12 parts of an acrylic resin dispersion liquid, 1-2 parts of isocyanate, 1-2 parts of calcium stearoyl lactate, 2-4 parts of zinc gluconate, 6-8 parts of table vinegar, and 4-5 parts of an auxiliary agent. The compound fertilizer has multiple nutrients, is low in production cost and good in slow-release effect, allows double coating to be formed on the nutrients by utilizing diatomite and a coating agent in the process, also contains various trace elements, has no toxicity and no pollution, and is excellent in quality of planted strawberry and obvious in yield and income increasing effects.

Color protection preservation method of poached green leaf vegetable instant product

The invention discloses a color protection preservation method of a poached green leaf vegetable instant product, belonging to the field of fruit/vegetable food processing. The method mainly comprises the following steps of: performing pretreatment, blanching for enzyme deactivation and vacuum infiltration soaking with a color protection and crisp protection agent (sodium alginate, calcium chloride, potato starch and zinc gluconate) of the green leaf vegetable; and performing secondary color protection preservation soaking by use of the color protection preservation liquid consisting of table salt, edible glycerin, sodium carboxymethylcellulose and sucrose ester. The method reduces the color protection preservation cost, and improves the color of the poached green leaf vegetable product stored in normal-temperature condition. The nano ZnO antibacterial liquid (in which a sodium hexametaphosphate dispersion protector with concentration of 0.015% is added) is subjected to vacuum packing and low-frequency (915MHz) microwave uniform sterilization. The storage temperature is normal temperature. Through the invention, good color and fresh degree of the poached green leaf vegetable instant product are kept in the normal-temperature storage period.
