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 meaning of crude oil EIA
- Changes in crude oil inventories actually reflect the attitude of the U.S. government on oil prices. If the strategic crude oil inventories increased significantly, indicating that the U.S. government recognized the oil price, it will increase the strategic inventory of crude oil resources, thereby increasing the supply and demand contradiction led to rising oil prices. Vice versa。Therefore, the difference between EIA crude oil inventories and OPEC crude oil inventories for the dollar is that the impact of EIA on the dollar exchange rate is more direct, but also greater impact.
- 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: What does it mean to buy and sell crude oil
- The spot is not the meaning of crude oil empty single positions, but short, popular is simply to buy down the list. Short of crude oil in the process of trading power to promote Huo Jia Ju Huang Wei Dan save one mode of operation of the means, when prices are expected to fall in future, according to the current price of crude oil will be in the hands of sell, so prices fell after the buy, access to post profits.
- Q: How to calculate the deposit of spot crude oil?

This is the embodiment of margin leverage, it is not what we say normally crunching, but in the transaction after the transaction 1~2 working days delivery procedures, although called the spot, but not for the sale of Readymade oil. A lot of spot crude oil investment customers do not carry out the actual transaction of crude oil after the transaction, but only due to the closing position to earn profit margin.What is the marginTo ensure the performance of the products stored in the transaction account, the bank account management funds. A simple understanding is that spot crude oil can be secured before the sale of the operation of the fund, it is also temporarily frozen, and when the deposit will be returned to the deposit account.
