Product Description:

Expansive oil well cement:

Volume contraction occurring during oil well cement hydration serves as the main reason that leads to poor bond of cement sheath interface, fluid (oil, gas or water) channeling in well and oil reservoir contamination. Under high temperature and pressure, the contracted volume in cement setting is 2.6-5.0% of total volume of cement slurry; while over 95% contracted volume is generated after final set. In plastic state, volume contraction of cement slurry will decrease pore pressure in cement slurry column (weight loss out of gelation) and lead to oil, gas or water invasion. After cement setting, volume contraction will cause trouble in cement bond between the cement sheath and stratum and casing and lead to a micro gap. This will affect cementing quality and cause great loss of oil and gas resources.

For the cementing quality problems caused by high contraction of oil well cement, our company developed expansive cement with many good properties, e.g. high strength, low filtration, anti-pollution, high temperature resistant and low free fluid.

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:Total energy consumption and total energy production
Any of the two secondary energy products produced by the conversion of various energy sources (including other non - energy products and associated products)
Q:What is a high value-added products
For example, river sand, chemical composition is silica
Q:What are the needs and pain points of new energy vehicles in insurance products and related services
The first consumer experience is not very good. Moreover, the first batch of the purchase of electric vehicles in the resale of second-hand car owners, but also encountered a thorny problem. Immature after-sales service with respect to traditional fuel vehicles have been mature after-sales service, new energy vehicles after the market, it seems not to see where the road".
Q:At present, what are the main types of new energy vehicles?
Fuel cell electric vehicle (FCEV):The utility model relates to a motor which is driven by a chemical reaction, and is driven by a motor. The energy of the battery is directly converted into electricity by the chemical action of hydrogen and oxygen, rather than by combustion.
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 types of new energy vehicles
2, 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:What is terminal energy consumption
1 as fuel, power use of energy refers to the energy into a variety of heating, power and other equipment, the production of light, heat, power consumption of energy2 as the raw materials used in industrial production. Energy refers to energy activities, as raw material is put into use, after a series of chemical reactions, gradually transformed into a new non energy products, such as chemical fertilizer plant for the production of synthetic ammonia, chemical factory production of synthetic rubber products such as the consumption of natural gas and coal coke consumption; production of dyes, plastics, textile products of raw oil.
Q:Which products need to be marked energy efficiency logo
As the first step in the construction of China's energy efficiency labeling system, household refrigerators and room air conditioner energy efficiency labeling system was officially implemented in March 1, 2005. According to the first batch of energy efficiency labeling product catalogue and related requirements, since March 1, 2005, every household air-conditioning and refrigerator production, sale, import Chinese must be labeled "Chinese energy label" label, no logo products will be allowed to market sales.
Q:Firewood (dry) is what type of energy
Representative biomass such as crop, crop waste, wood, wood waste and animal waste. Narrow concept: biomass mainly refers to the agriculture and forestry production in addition to food, other than fruit stalks, trees and other wood cellulose (referred to as lignin), Agro industrial waste, agricultural waste and animal husbandry production process such as manure and waste materials. Features: renewable, low pollution, widely distributed.
