China high density frac chemicals for industrial production with superior conductivity

Wanli has been devoted to introducing, absorbing, applying and re-innovating the technology for more than 20 years. We have 8 ceramic production lines and 4 full-automatic resin coated sand production lines, which guarantee the ceramic proppant's annual output to reach 280,000MT and the resin coated proppant to reach 120,000MT. So far, we have provided over 1million MT products to the world and meet different oil & gas fields’ demand both in home and abroad, and the products get consistent praise by customers.

Our products have passed industrial certification. We have constituted a sound QHSE management system according to ISO, API, and OHSAS standard. 

Since 2010, our productshave been tested regularly by the Reservoir Stimulation Laboratory of RIPED-Langfang PetroChina, Stim-lab, Prop-Tester and Frac-Tech lab, which prove our products have the properties of high temperature resistance, high pressure resistance, high strength and high conductivity.

Our ceramic proppant can be classified as follows:

By trademark: WL Lite WL Isp WLHsp

By compression strength: 52MPa(7500psi), 69MPa(10000psi), 86MPa(12500psi), 103MPa(15000psi).

By specifications: 6-12mesh, 8-16mesh, 12-18mesh, 12-20mesh, 16-20mesh, 16-30mesh, 20-40mesh, 30-50mesh, 30-60mesh, 40-60mesh, 40-70mesh, 70-140mesh, etc.

Moreover, we can produce products with different specifications according to client’s particular requirements.

The raw materials are proportioned by the computer after being carried into the storage bins and crushed into powder by the cylinder ball mill, then, blown into storage bins through pipes in which the materials are fully mingled.

Next, the powder is delivered to pelletizing workshop; get spraying pelletized by rotary granulators with diameter of 4m. The beads then are dried, dedustied and sieved by multi-functional screen.

Semi- finished product will be sintered in rotary kiln, and then get cooled, dedustied and rescreened. Eventually the finished product are packed and stored in warehouse.

In the raw material procurement process, WANLI processes advantage of abundant mineral resources nearby. The process is controlled strictly with comprehensive sampling and testing.

In pelletization process, with the automatic control system, WANLI can immensely reduce the consume of electricity and detritions of equipment, thus cutting down costs.

In sieving process, the patented multi-functional screening sieve invented by WANLI can perform the screening and inspection repeatedly with high efficiency. All particles will go through 4 systems controlled by the screen of combined rotary drum sieve to tally with the required size range.

In storage process, there is specialized finished product warehouse in the factory. The finished product will be packed and stored in the warehouse where the industry standards are strictly enforced especially the damp-proof and moisture-proof measures.

Packing: 1.5 net weight ton bags, plastic bag for inner packing, woven bag for external packing. Other packaging are available.

Delivery: Within 30 days.

It will take 8 hours from Wanli factory to Qingdao port or Lianyungang port by truck. It will take 40-50 days by bulk cargo to USA, and 35-45 days by container.
