Company Profile

Introduction Baiyin Jinqi Chemical Technology CO., Ltd.was established in July, 2006. It locates in the National High-tech Industry Development Zone of Chinese Academy of Science of Baiyin City. The company is well-equippedwith fine equipment, qualified staff and high standard inspection methods. After years of development, its total assets mount to 26 million US dollars. The company is fully capable of producing annually 50 thousand tons of new-type oil field well cement lightening agent BYJ-1,[MORE]

 New-type Well-cement Lightening Agent
Oil well cement lightening agent which directly affect the index of density and compressive strength of concrete in oil well is the main external additive applied in low density grout well-cement technology. High quality lightening agent makes the concrete grout stable with high rheological property, high compressive strength, compact structure, low water loss, low free fluid, low penetrance, no shrinking and anti-fluid channeling.
Our product, well-cement lightening agent BYJ-1 is made from new types of compound lightening-empowered materials of utralight silicon aluminum. The low density well cement concrete grout features low density, low bleeding, high intensity, high rheological performance and stability after the use of BYJ-1. With the use of our lightening agent, problems of oil-well cementation such as low pressure, leakiness, long-time Well-cementation and the protection of oil & reservoir can be solved, as well as the effective protection of the quality of well-cement equipments.
Our product features the following performance:
1.Pumpability
Due to the low water absorption of the material, water is reduced in the blended grout. As a result, given the same amount of water, the ultra-low-density concrete grout performs better fluidity than common grout
2. Thermostability and Durability
As the materials consisting of various kinds of ultra-light silicon aluminum, the grout is improved with its thermostability for high temperature conditions by preventing the decline of concrete strength caused by high temperature, especially in high temperature oil well cement. At the same time, the durability and anti-permeability of the concrete stones are enhanced by preventing the strength declining with the passage of time.
    3. Low water loss
The compounds of carboxyl and hydroxyl water-soluble polymers can be absorbed on the surface of concrete particles, forming a layer of absorbed hydration shell, bridging concrete particles within a web pattern, blocking more free water and interspaces between concrete particles and lowering the permeability of concrete filter plate. On the other hand, the materials make grout to have certain thickness, which prevents dehydration and water loss.
4. Low cost
Well cement lightening agent BYJ-1, is produced with high-tech skills and advanced technology, it ensures deep well pressure and construction safety, which enables effective lowering in cost.
