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:Spot crude oil has several investment?
Spot oil trading refers to buyers and sellers from the investment demand for real oil and crude oil sales real purpose, according to the agreed payment and delivery, immediate or a real trading settlement of crude oil in a relatively short period of time. In spot transactions, with the transfer of ownership of goods, while the completion of the exchange and circulation of crude oil. Therefore, crude oil spot trading is a direct manifestation of the operation of crude oil products.
Q:How to understand the change of U.S. EIA crude oil inventories, please enlighten prawns!
The crude oil inventory is down 4 million 960 thousand barrels, significantly higher than the expected 1 million 800 thousand barrels, making the U.S. crude oil prices have a larger increase
Q:NYSE crude oil futures have no limits on the day up or down
No rise or fall limit.New York futures exchange light crude oil:Because of the strength of the United States super oil buyers, coupled with the impact of the New York stock exchange itself, to WTI as the benchmark crude oil futures trading, commodity prices in the global commodity futures became the leader.
Q:What is the difference between crude oil and gold?
Changes in crude oil prices directly affect the operation of the oil exporting countries to gold, which led to fluctuations in the price of gold. Oil producing countries, such as Saudi Arabia, Qatar, the United Arab Emirates, Kuwait, Iran and other places are mostly concentrated in the Gulf region, mostly Arabia countries, holding huge amounts of crude oil. When the international gold price fluctuations, they often have the same direction to the operation of the oil dollar.In order to transfer the risk of crude oil exporting countries often put oil dollars a huge part of the investment on the international financial market, and gold as a good tool to avoid risks, investment, natural in the crude oil selection in abroad.The price of crude oil rose period, held by the producers of crude oil dollar rapid expansion, so these countries will increase the proportion of gold in its international reserves correspondingly, increased demand for gold in the international gold market, thus promoting the rise in the price of gold.
Q:Do spot crude oil should be how to operate it?
The fourth step: the combination of theory and PracticeUnderstanding of the above knowledge, you can simulate the transaction to practice, practice is the fundamental understanding and improve the level of crude oil trading. Note the need to pay attention to the simulation of the transaction: 1, light warehouse orders, avoid heavy. 2, develop the habit of setting stop.Also need to note that the simulated trading and the actual transaction is different, the most essential difference is the different mentality, not only for beginners, many experienced investors would do well to simulate the actual transaction, but bleeding money situation. So, from the simulated transactions to the actual transaction, we must adjust their mentality, to maintain a normal heart can be.
