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.

The control positions, to abstain from greed and gambling.5, if you stare at the disk time is limited, it is not suitable for short-term operation. Midline operation, in particular, should take advantage of the light positions, decisive stop, reverse the signal appears profitable. In order to avoid the long-term operation of margin trading, explosion-proof silo risk and missed profit and loss prevention, stop time.6, spot crude oil trading time: trading time is based on Beijing time, Monday morning 7:00 to 4:00 am on Saturday.
- Q: Which futures varieties susceptible to crude oil prices?
- Because the relationship between transportation costs are basically more or less affected
- Q: What does it mean for spot crude oil?
- That is the so-called margin deposit, that is when you need to pay for each transaction by deposit, so what are you currently occupy the margin accounts inside how much your trading account. The more the number of operations, the more the deposit will be occupied. This shows that the margin is not deducted from the cost, only temporarily marked as a margin, and can not be repeated for sale. After the transaction is completed, it will again become your available balance.
- Q: What is the impact of the initial jobless claims on crude oil
- Unemployment is an economic data on the number of unemployed people in the United States to receive unemployment compensation.
- Q: What is the relationship between the price of crude oil and the European and American stock market
- And this speculation will further push up the commodity futures prices, but the high price of crude oil futures will exacerbate the producer concerns and further suppress the U.S. economy, investors are expected to reduce the deterioration of the environment and the economy, reflected in the stock market's stock market fell. The decline in the stock market will further exacerbate the vicious circle, capital fled, pushing up the futures, and ultimately lead to inflation. To avoid this vicious cycle, central banks often have to take action to control the supply of money to avoid excessive fluctuations in currency exchange rates.
- 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: 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: How many barrels of crude oil
- We have tons of barrels and is common. The number of units of crude oil OPEC and the western countries used barrels, and China in Russia and other countries are commonly used metric tons of barrels respectively. Because of the quality and volume of the unit, and the variation range of the density of crude oil is large, so only the fixed conversion method, and no fixed conversion ratio.
- Q: Why is the "barrel", and American barrels, rather than some of the more authoritative and accurate quality unit?
- The answer to the second question is traditional and customary practice.When it comes to oil "bucket", you probably think of first is the kind of sweet potato baked roadside black steel. In fact, the early barrels of oil are wood. At the beginning of 1860s, crude oil storage and transportation and trade with wooden barrels as the main form of packaging. A carriage can hold 8 barrels of oil. The driver, horses, carts, and casks carry crude oil from the side of the derrick to the railway station and dock. Oil pipeline in 1865, in 1878 the first oil tanker in the Caspian Sea maiden voyage, in 1883 the railway oil extended from North America to the hinterland of the caucasus. 42 gallons of wooden barrels
