Abstract

The invention discloses a preparation method of a petroleum propping agent. The method comprises the main steps that S1, firstly, raw materials are smashed and screened, raw materials with the grain size being not larger than 5.5 mm are collected, and the raw materials not meeting the requirement for the grain size continues to be subjected to the smashing process for use; S2, according to the weight component, the prepared raw materials are ground, screened and heated to 300-350 DEG C for use; S3, the materials in S2 are stirred and heated under the constant temperature of 150 DEG C, then, acuring agent, a lubricating agent and a surface active agent are added in sequence, and stirring continues to be performed for 2 min for use; S4, the materials in S3 are cooled, smashed and screened to obtain a finished product.

Description

technical field [0001] The invention relates to a preparation method of petroleum proppant. Background technique [0002] Petroleum proppant is also called petroleum fracturing proppant. During oil and gas deep well mining, high closure pressure and low permeability deposits are treated by fracturing to crack the oil-gas-bearing rock formations, and oil and gas are collected from the channels formed by the fractures. At this time, fluids need to be injected into the rock base to overcome formation fractures Intensive pressure creates cracks in the rock formations around the wellbore, forming a channel with high-level flow capability. In order to keep the cracks formed after fracturing open, oil and gas products can pass through smoothly. [0003] Currently commonly used proppants mainly include quartz sand, bauxite ceramsite sand and resin-coated composite particles. Quartz sand is widely used because of its low cost and low density, which is easy to pump. However, its low...
