How to Manufacture Chinese Oil & Gas Drilling Proppant: Step-By-Step Guide
Step 1: Raw Material Preparation
The first step in manufacturing Chinese oil & gas drilling proppant is to prepare the raw materials. These materials typically include bauxite, kaolin, and other minerals. The raw materials are crushed and ground into a fine powder before being blended together in the desired proportions.
Step 2: Mixing and Forming
Once the raw materials are prepared, they are mixed together with water and other additives to form a slurry. This slurry is then poured into molds and compressed at high pressure to form spherical pellets. The pellets are then dried to remove excess moisture.
Step 3: Sintering
After the pellets are formed, they are sintered in a rotary kiln at high temperatures. This process helps to strengthen the pellets and improve their crush resistance. The pellets are heated until they reach a specific level of ceramic-like hardness.
Step 4: Coating
Once the pellets have been sintered, they are coated with a resin to further enhance their strength and durability. The coating also helps to improve the adhesion of the proppant to the fracture walls in oil and gas wells.
Step 5: Quality Control
Throughout the manufacturing process, quality control checks are performed to ensure that the proppant meets the required specifications. This includes testing for crush resistance, roundness, and sphericity. Any pellets that do not meet the quality standards are discarded.
Step 6: Packaging and Shipping
The final step in the manufacturing process is to package the proppant in bags or bulk containers for shipping to oil and gas drilling sites. The proppant is carefully packaged to prevent breakage and contamination during transport.By following these steps, Chinese manufacturers can produce high-quality oil & gas drilling proppant that meets the demanding requirements of the industry. The manufacturing process requires careful attention to detail and strict quality control measures to ensure the proppant performs effectively in hydraulic fracturing operations.
