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:What are the tax policies for renewable energy companies?
- First, there is no exemptionThe development and utilization of support for renewable energy, energy consumption structure for improving our country's great significance, with the speeding up of the rapid economic development and energy consumption, China's renewable energy development and utilization of tax policies to support increased year by year.The vat has 5 main: since January 1, 2001, belonging to the biomass energy waste generation implementation of VAT refund policy; since January 1, 2001, the wind power generation value-added tax levied policy; since 2005, the denatured fuel ethanol production and marketing enterprises designated state approval of the sale of VAT refunds; in the county the following small hydroelectric power production units, according to a simplified method in accordance with the 6% tax rate to calculate VAT; VAT rebate policy for hydropower enterprises.Consumption tax, since 2005, the state approved the production and sales of fixed-point fuel ethanol production enterprises to be exempted from the consumption tax policy. Part of the tax preferential policies, although only applicable to individual enterprises, but played a good role model.
- Q:What are the new energy products
- Solar products: solar street lights, solar water heaters, etc.Nuclear energy: nuclear powerOcean Energy: wave power, tidal powerWind power: wind powerBiomass: made of liquid or gaseous fuels
- 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:Just hired, listen to the boss, in the United States seems to be subject to tariff barriers, it seems that Europe has to impose punitive tariffs...... Would like to ask the industry, the market will be the future development of the market?
- Because of the decline in the cost of photovoltaic, trade stocks are devalued. Which buyers and sellers do not want to bypass the two dealers
- Q:Can the total energy consumption (equal value) be calculated in terms of the sum of the equal value of electricity and other energy
- Energy consumption: unit energy consumption is the main index to reflect the level of energy consumption and energy saving, the ratio of primary energy supply to gross domestic product (GDP) is an indicator of energy efficiency. The index shows the degree of energy utilization in a country's economic activities, reflecting changes in economic structure and energy efficiency.
