Product Description:

It is a kind of solid resin coated moulding sands or core sands by using the high quality natural silica sand as raw sand, thermoplastic phenolic resin, urotropin and enhancer as other materials. It is used in the oil and gas fracturing process to support, prevent flow back and increase the production.

How resin-coated sand comes?

As the proppant's flowing back appears in some oil and gas wells after the fracturing, it will negatively impact on fracturing result and the flowing back proppant will destroy the equipment in the well and above-ground. For this kind of well, we should take effectively control measures to prevent the flowing back and ensure the fracturing result

Feature of resin-coated sand

It has the feature of low density (lower than silica sand), easy-pumping, anti-corrosion and high temperature resistance. Besides, it provides good performance of oil penetrating and water blocking.

That's of great significance to continuous stable and high production of low permeability oilfield exploiting and development in the mid to late. But its crush rate will increase along with the rise of closure pressure.

That will narrow the crack width with the effect of resin elastic deformation, grain crushing and rearrangement. Then it will affect the porosity and permeability of the generated cracks

Raw materials of producing resin coated sand:

Silica sand, resin, assorted curing agent, urotropine, calcium, KH-550, epoxy resin curing agent and O-type toughening agent.

Performance of Resin-coated Sand:

1. Low density. Because of low density, the amount of proppant used in fracturing was decreased in the equal crack size. And it can also reduce the carrying fluid consumption to reduce fracturing cost.

2. Good roundness & sphericity.

3. High crush resistance.

4. Low turbidity.

5. Low acid solubility. After resin coated, the sand acid resistance, alkali resistance and salt resistance are enhanced.

6. Good long-term conductivity. The RCS wraps most of the broken sand crushed under high closure pressure, even if the sand is crushed, the debris and fine powder are wrapped in a resin shell to avoid their migration, providing a good conductivity.

Q:What is the difference between foreign exchange and crude oil?
Foreign exchange transactions refer to the way in which a foreign currency is bought in one currency and sold in another currency. In the international market, the exchange rate of various currencies fluctuates frequently, and it is traded in the form of currency.
Q:What is the relationship between EIA and the price of crude oil?
EIA released by the U.S. energy information agency statistics, published every Wednesday night is summer time 22:30, winter time later postponed for an hour. Spot crude oil market traders and international authoritative energy consulting agencies are using EIA inventory data. This data mainly shows when the weekly crude oil inventory data change Shi performance save search front burning gnawing Shi Vollmer are, will have a major impact on the trend of international crude oil.
Q:Crude oil futures trading skills?
Learn the futures investment skills, there are more opportunities for profit. New speculation of crude oil futures and commodity futures, commodities to be actively involved in a large loss of profits of small, when commodity prices are below the cost of production or more than the occasion of sales profits, investors should be based on the reasonable control of the capital, consider bargain gradually built more gradually building space or the rallies, large profit to get the price back the operation result.
Q:What is the mode of operation of crude oil?
Margin trading: leverage principle, the lowest 5% of the income, the funds can be enlarged by 20 times, fully improve the efficiency of the use of funds.5, no delivery: do not have to be like futures as a result of delivery must be done, but also reduce transaction costs.6, the global market: with international standards, no banker manipulation, open and transparent market information
Q:What is the meaning of ADP data, and the relationship between spot crude oil
Published value is greater than expected, favorable U.S. dollars, bad crude oil.The announcement refers to less than expected, bad dollar, bullish crude oil.(negative correlation between us dollar and crude oil)
Q:Spot crude oil with the difference between stocks and futures?
Futures Crude oil is a kind of futures, which is based on forward oil price. The uniform standard of crude oil is formulated by the futures exchange. Many investors do not understand the difference between crude oil and crude oil futures
Q:EIA how to make a single spot crude oil
Crude oil inventory data on the basic judgment done, how to operate it? According to the actual value of the published we can make the following judgment: if the actual value is greater than the predicted value and greater than the previous value, then it must be bad. Because the stock has increased! On the contrary, the actual value is less than the predicted value and less than the previous value. Similarly inventory reduction! Can increase (decrease) based on the amount of inventory to do more than short or other layout operations! If you are in the middle of the value, then Xiaobian recommended not to do a single, long and short are possible, the risk is greater than the profit, there is no need to take the risk!
Q:What is the relationship between crude oil and gold and silver?
Gold prices are positively correlated with crude oil prices. Gold and crude oil are mainly denominated in dollars. Gold is a hedge against inflation, and rising oil prices mean inflation will follow, and the uncertainty of economic growth will increase.
Q:Petroleum crude oil on the human body what harm?
Quality solutionDue to the volatile benzene, exposed to the air. It is easy to spread and animal inhalation or skin contact with a large number of benzene into the body, can cause acute and chronic benzene poisoning. According to the report, partly caused by benzene poisoning is due to in vivo production of benzene phenol.
Q:How much does it cost to open an account?
Some platforms can operate thousands of pieces, the formal large platform generally have a threshold of 30 thousand to about $50 thousand. The amount of money not to operate the recommended amount of money is too small, too small is not easy to operate, large capital it can predict the market operation is very good, full warehouse operation you can double the profit, you don't have to worry about loss, big platform has financial analysts, can also give you a sign investment contract.
