Superfine oil well cement:
It is the cement with certain grain gradation, made from Portland cement clinker mainly composed of hydraulic calcium silicate, and appropriate amount of gypsum by finely grinding. It has the characteristics of strong infiltration ability and extensive density adjustment range. The superfine oil well cement can meet special requirements for oil well cementing, e.g. cement squeezing, water plugging, leakage stopping, micro pore filling and etc. Besides, it also can be applied to new fields such as low density cementing, reservoir cementing and high pressure cementing, etc. At this stage, there is no national or industrial standard available, and the enterprise standard is mainly executed.

- Q: Metro energy feedback products which good?
- Then the annual cost savings of 4.86x350x365=620865 yuan. If you are interested in further understanding can be concerned about Sheng Hong electric WeChat public number in the above there are a lot of introduction of the article, you can also direct contact 0755-86511588, will be a detailed answer
- Q: What are the sources of energy that are common in life and the two energy sources
- The two energy is converted into the form of energy. For example, if coal is used directly to burn, we are using the primary energy. If coal is used to generate electricity, the electricity generated is the two energy.
- Q: State approved products called new energy foods
- The difference between new resource food and health food:1 health food refers to food with specific health functions, and approval must also be clear that what has a health care function, and the need for a health care function marked and defined on the product packaging, the new food resource has one or more functions are not on the product introduction mark in detail.2 new resources of food and health food for the application of the crowd is different, the former applies to any population, while the latter is suitable for specific populations.
- Q: What is the classification of energy?
- Energy can also be divided into different types. There are seven main points: the source is divided into the following 3 categories: the energy of the earth itself usually refers to the earth...
- Q: What are the contents of bio energy
- Biomass includes plants, animals and their waste, garbage and organic waste water and other categories.
- Q: Total energy consumption and total energy production
- For example, the electricity generated by the thermal power generation, cogeneration of electricity, steam, hot water, coal washing coal washing, washing coal, slime, coking coke, coke oven gas and other coking products
- Q: Trademark registration of energy and environmental protection is the first category
- Article 06: common metals and their alloys, metal building materials, transportable buildings of metal, metal rails, non electrical cables wires, five metal fittings, officer, safe, general metal products not included in other classes, oreClass 07: machines and machine tools, motors and engines (except for land vehicles), machine transmission couplings and transmission parts (except for land vehicles), non manual agricultural tools, incubatorsArticle 08: hand tools and implements (manual), cutlery, knives, razorArticle 09: Science, navigation, surveying, electrical, photography, film, optical, weighing, measuring, signal, inspection (supervision), ambulance (rescue) and teaching apparatus and instruments, apparatus recording, transmission or reproduction of sound and image, magnetic data carriers, recording discs, since the mechanical structure dynamic sales device and coin operated devices, cash register, computer and data processing device, fire extinguishing apparatus
- Q: What is the energy consumption per unit product
- Formula: (1) comprehensive energy per unit of product yield comprehensive energy consumption per unit of product yield consumption = production of comprehensive energy consumption of the product (equivalent) / qualified product yield (2) yield of single unit product energy consumption per unit of product yield of single energy consumption = production of the product consumption of a variety of energy the number of qualified products yield (3) than the unit energy consumption of products according to the standard procedure to calculate the energy consumption than the unit energy consumption = comprehensive energy consumption according to the standard calculation of the amount of qualified production process / product yield can be calculated according to the standard energy consumption than single bit = yield statistics method of comprehensive energy consumption volume / year range: standard products report on the production of major products for the annual energy consumption of 5000 tons of standard coal and above the legal unit. The index of the sub item is the production of a product of a number of varieties of the total energy consumption of energy, not including production has nothing to do with the amount of energy for the purpose of life, nor does it include internal recycling energy and enterprise basic construction unit consumption using waste heat and gas; mother is qualified, have procedures for storage products production.
- Q: Coal washing products are primary energy, or the two energy?
- Do not change the shape of coal washing, just reduce the impurities contained in it; coal washing process does not like cracking on oil, coal coking gas, various fuels like will produce high-temperature flue gas, combustible gas, waste steam and load pressure fluid and other available substances. Coal washing process loss of selected substances is only a small amount of coal in mixed sublation in it, this conversion and other primary energy saving, waste rate nap: side, more importantly, in the coal washing and processing did not release any energy, is not the "first time" to be used as a source of energy use.
- Q: What is the cost effectiveness ratio of energy management in energy quality?
- More and more countries pay attention to the energy efficiency of electrical products in the world, and now many countries regard the energy efficiency requirements as one of the mandatory targets for the sale of the products:EU: ErP (instead of EuP), European flower, CoC...United States: Energy Star (Energy Star), CEC, DoE...Canada: NRCan,Australia: MEPS,Korea: MEPS,China: CECP,
