About zhengnai

Henan Zhengnai New Materials Co., Ltd. was established in 2002 with a registered capital of 50 million yuan. The company is located in the South Fourth Ring Road, Zhengzhou City, Henan Province. Due to the urban planning of Zhengzhou City, the company moved to No. 90, Weisan Road, Wenxian Industrial Cluster, Henan Province in 2015 through the investment of Wenxian County People's Government of Henan Province. Taking this as an opportunity, the company plans its layout from a high starting point and adheres to the development concept of "science and technology, harmony and win-win" of Henan Zheng Nai. Improve production equipment automation, plant environment, talents and technology in an all-round way. Main R&D and production: oil fracturing proppant series products; Special wear-resistant new material series products.
The annual output of ceramsite sand proppant is 120000 tons in 16/20 mesh, 16/30 mesh, 20/40 mesh, 30/50 mesh, 40/70 mesh, 70/140 mesh and other specifications, 50000 tons of coated sand and 150000 tons of quartz sand for fracturing. The products are mainly used in oil and gas and shale gas exploitation and fracturing projects, and have the characteristics of effectively increasing production and prolonging the life of oil and gas wells.

Research status and progress of functional fracturing proppant used in oil and gas development (I)

When oil and gas are exploited in deep wells, after fracturing treatment of high closing pressure and low permeability deposits, the oil and gas bearing strata will split, and oil and gas will flow out of the channel formed by the fractures. At this time, fluid needs to be injected into the rock base to exceed the pressure of the formation fracture strength, so that the surrounding rock layer around the wellbore will produce fractures, forming a channel with high flow capacity. In order to keep the fractures formed after fracturing open, oil and gas products can pass through smoothly. With the high pressure solution, the oil proppant is used to enter the formation and fill in the rock fractures, which plays a role in supporting the fractures not to be closed due to stress release, thus maintaining high conductivity, making oil and gas unblocked and increasing production.

Research status and progress of functional fracturing proppant used in oil and gas development (II)

Although hydraulic fracturing technology can increase production, it will cause groundwater pollution. The circulating water contains chemical substances used for hydraulic fracturing treatment, naturally produced concentrated brine, and a small amount of radioactive substances, such as Ra-226, Ra-228, Th-232, and U-238. In order to avoid environmental pollution, further treatment of circulating water is required. Researchers found that this problem can be solved by synthesizing water treatment proppant. This kind of proppant is harmless to the circulating water by compounding the radioactive material absorbent and hazardous chemical reagent absorbent.

Huge development potential of fracturing proppant industry driven by rapid development of oil and gas industry

Fracturing proppant, also known as oil fracturing proppant, is a kind of natural sand or artificial high-strength ceramic solid particles with certain particle size and strength, certain sphericity and grading. The working principle of fracturing proppant is that when oil and gas are exploited in deep wells, it enters the stratum together with high-pressure solution to fill in the rock fractures, supporting the fractures and increasing the oil and gas production. Fracturing proppant is characterized by high strength, low pollution, good corrosion resistance, strong conductivity and high temperature resistance, and is mainly used in oil and gas well production.

Qinyang City Friends Machinery Equipment Co., Ltd.

What technical and environmental barriers do China's shale gas break through

With our efforts in the past two years, first, we have broken through the shale gas outlet barrier and solved the problem of whether China has shale gas. In Sichuan mining area, gas is basically produced from wells, and some wells have obtained high gas flow. At the same time, the key technologies such as horizontal well drilling and staged fracturing have been preliminarily mastered.

Application method of ceramsite proppant

Coating resin on the surface of sand or ceramsite can further improve the strength and conductivity of proppant. Proppant is the key material for fracturing construction.

What is oil fracturing proppant (ceramsite sand) used for

The most popular saying is that the~~~used for oil field production increase and the adhesive of a chemical commonly known as guar gum are bonded together, and then the ceramsite is pressed into the fractures of the formation, and then the oil can flow out through the channel formed between the ceramsite
