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 crude oil? How produced
Crude oil extraction of oil from the bottom, usually at the wellhead through simple oil-water separation into oil and gas gathering and transportation pipelines, where oil production process did not enter the pipeline leak from oil or oil pipeline in oil and oil production area scattered on the ground (such as criminals from being oil pipeline punctured steal oil caused by the oil spill), usually called "falling oil"
Q:Yesterday crude oil data bullish, how did it fall so much? How should we operate today!
If you want to operate crude oil short-term trading, you can find an analyst, analysts always tell you the trend of the market, bullish bad all crude oil traders will be active together.I think the real deal between small partners to communicate with each other and analysts look at the trend, interesting.
Q:International crude oil transaction is equal to how many tons
New York Mercantile Exchange crude oil futures contract is 500 barrels. CFD transaction is the smallest unit of 0.1 hands is also a barrel of 100.
Q:What to do to pay attention to spot crude oil
Just contact for the investment market in terms of friends, all parameters should be used to simulate the first account of skilled software above, such as open and close operation, how to lock lock, there is a few hands needed to do. General system will fix your last hand. So be sure to do a good job before the real operation of the software platform.
Q:What is the meaning of crude oil inside the lock?
Suocang is holding more than one and the same number of empty single, such a role is to avoid excessive volatility in the market when the wrong risk, if the market is up more than a single profit
Q:Crude oil rose, gold and silver will rise? What's the relationship between them?
