Product Description:

Deep-sea low-temperature and low-density oil well cement: 

The deep sea water is of low temperature, high pressure, low formation fracture pressure, with commonly associated shallow flow and natural gas hydrate. In the past, the low-density foam cementing for deep sea cementing at a low temperature was adopted, which often involves with complicated construction processes, various changing factors and high cementing risk.

The deep-sea low-temperature and low-density oil well cement developed by our company mainly contributes to overcoming the deficiencies of slow strength development and high density of conventional oil well cement. At the temperature of 5 , the strength can reach above 3.5MPa after 8 hours. Moreover, the slurry density is controlled within the range of 1.50±0.02g/cm3.

Q:At present, what are the main types of new energy vehicles?
Hybrid electric vehicle:Refers to the use of conventional fuels, while with motor or engine to improve low-speed power output and fuel consumption models. In accordance with the different types of fuel, hybrid vehicles can be divided into two types of gasoline hybrid vehicles and diesel hybrid vehicles. At present, the mainstream of hybrid vehicles in China are mainly gasoline hybrid, while the international development of diesel hybrid models are relatively fast.
Q:Firewood (dry) is what type of energy
It includes plants, animals and microorganisms. The concept of biomass includes all plants, microorganisms, animals, plants, microorganisms, and waste products
Q:What is a high value-added products
A lot of houses sold with only a few dollars. But from the spoon river sand refined silicon processing into CPU
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 is the general energy?What do we usually say about energy conservation?
Chapter I General ProvisionsArticle 1 this law is enacted for the purpose of promoting energy conservation, improving energy efficiency and economic efficiency, protecting the environment, ensuring the development of the national economy and society, and meeting the needs of the peopleSecond energy resources referred to in this Law refers to coal, crude oil, natural gas, electric power, coke, coal gas, heat, refined oil, liquefied petroleum gas, biomass energy and other directly or through processing, conversion and made useful to the various resources.
Q:What is the C type of the product type in the notebook computer?
A class of products such as high priced cars, real estate, etc. must have a certain psychological cognitive process,
Q:Energy Star certified product range
Upstairs to answer the news, is the United States energy saving certification, a lot of IT, TV/AV products have to do energy star; but the United States has a California CEC certification, but also energy-saving certification, but different from the energy star
Q:Which products need to be marked energy efficiency logo
China is the world's largest producer and consumer of household electrical appliances. The rapid growth of household appliances has brought huge energy consumption, but also increased the pollution of the environment. Countries around the world through the development and implementation of energy efficiency standards, the promotion of energy efficiency labeling system to improve energy efficiency of energy efficient products, and promote energy-saving technological progress, thereby reducing emissions of harmful substances and environmental protection.
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:What are the new energy sources?
Combustible ice: This is a solid compound of methane and water, which is similar in appearance to ice". Combustible ice is stable at low temperature and high pressure, and the combustible gas released by ice melting is 100 times that of the original solid. It is estimated that the amount of combustible ice is more than the total amount of coal, oil and natural gas on earth.Coalbed methane: during the formation of coal due to the increase in temperature and pressure, while the deterioration of the release of combustible gas. From peat to lignite, per ton of coal produced 68m3 gas; from peat to coal per ton of coal produced 130m3 gas; from peat to anthracite coal per ton of coal produced gas 400m3. Scientists estimate that the earth's coal-bed methane up to 2000Tm3.
