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:How many liters of a barrel of crude oil
U.S. 1 gallon =3.785 liters, 1 inch gallons = 4.546 liters. If the volume converted into weight, and the density of the crude oil. If a real estate of crude oil density of 0.99 kg / L, then a barrel weight is 158.98 * 0.99= 157.3902 kg
Q:What time will the oil warehouse explosion
. because of the leverage effect of margin trading, it is prone to explosion caused the warehouse explosion, if investors need to make up the deficit and the deficit or face legal recourse caused by investors.
Q:What is the difference between refined oil and crude oil
In the pipeline transportation of crude oil than the major transport difficulties, and the proportion of refined oil is easy to transport
Q:What is the spot crude handling charge? How to calculate?
Transaction fee is a kind of labor compensation for the company to provide assistance, services, technical support and other related matters.Standard: 8/10000 / 6/10000 of the turnover
Q:Do spot crude oil should be how to operate it?
The third step: fundamental analysisMany traders ignore the fundamentals of the analysis, more fancy technical data analysis. Crude oil market is a global market, the data is large, the terminology is very professional, ordinary investors have no time to take into account all the information. But we still need to understand some of the most commonly used data concepts.
Q:Why is the New York Mercantile Exchange lower than the Brent crude oil futures price
New York light crude oil is a kind of common North American crude oil, the sulfur content is 0.24%, mainly from the western United States and Mexico Gulf Coast refineries.Light crude oil futures contracts in terms of value and scale are the world's largest, is the world's crude oil pricing benchmark.Beihai Brent crude oil is Europe's benchmark light crude oil, slightly higher sulfur content, 0.37%, mainly from the northwest European refineries.As the United States crude oil pricing benchmark WTI crude oil sulfur content (0.24%) is much lower than the Brent crude oil (0.37%), the equipment and process requirements are relatively high, and therefore more welcome by oil refining enterprises.
Q:International crude oil transaction is equal to how many tons
The NYSE margin ratio is generally about 1:20, trading with standard hand occupied margin is about $5000, $2500 is small; the CFD margin is generally about 1:100, trading with standard hand occupied margin is $1000, 0.1 $100 entry is relatively low, but CFD not delivery of real transaction.
Q:U.S. crude oil reserves to increase crude oil is good or bad
Increase in crude oil stocks on the stock to reduce excess oil. Inflation and deflation are a reason
Q:How crude oil refined oil, in addition to gasoline can be extracted out of something else
According to the difference of boiling point of the group, from crude oil refining straight run gasoline, kerosene, diesel oil and lubricating oil distillate severity grading, a process that is crude oil. Then these semi-finished products in some or most of the two crude oil as raw material, processing, refining process, such as catalytic cracking catalytic reforming, hydrocracking and other backward, can improve oil product quality and the yield of light oil.
Q:Do spot crude oil, the minimum threshold is how much money ah?
Platform generally does not require that some of the members of the unit will be set up with the agency, there is no threshold limit, but the lower the risk of funds, because the spot crude oil is a margin trading system, there is a lever. As long as the minimum input to meet the amount of operation can be. But crude oil products involve a lot of specifications. And each platform supports the specifications are not the same. Some companies support 1T, 5T, 15T, 20T, 100T, etc..
