Oil proppant is also called oil fracturing proppant. When deep oil and gas wells are exploited, the high closure pressure and low permeability ore deposits are subjected to fracturing treatment to crack the oil and gas-bearing rock layers, and the oil and gas are collected from the channels formed by the cracks. At this time, fluid needs to be injected into the rock base to exceed the formation fracture. The intense pressure causes cracks in the rock formations around the wellbore to form a channel with high-level flow capacity. In order to keep the cracks formed after fracturing open, oil and gas products can pass through smoothly.
