Description

Technical Field

[0001] The utility model relates to the field of fracturing, in particular to a continuous sand conveying device for a fracturing sand pier. Background Art

[0002] The continuous sand conveying device of the fracturing sand pier is a key equipment used in the hydraulic fracturing operation of oil and gas fields. Hydraulic fracturing is a technology to increase the production of oil and gas wells. It injects fracturing fluid (usually a mixture of water and chemical additives) into the oil and gas layer under high pressure to create cracks in the formation, and then injects proppant (usually sand or artificial ceramic particles) into these cracks to keep the cracks open, thereby increasing the fluidity and production of oil and gas. During the hydraulic fracturing process, the role of the continuous sand conveying device of the fracturing sand pier is to continuously and evenly convey the proppant into the fracturing fluid and then inject it into the formation together. This device needs to have the characteristics of high reliability, high efficiency and precise control to ensure that the proppant can be mixed with the fracturing fluid in a predetermined proportion and speed, thereby ensuring the success and effect of the fracturing operation. With the continuous advancement of oil and gas field development technology, the requirements for the continuous sand conveying device of the fracturing sand pier are also getting higher and higher, including higher conveying capacity, more precise control, lower failure rate and longer service life.

[0003] At present, during the use of the continuous sand conveying device of the fracturing sand pier used in the early oil field development, the fracturing sand will accumulate during the sand conveying process. The accumulation will cause the sand to clump, which is easy to cause the fracturing effect. At the same time, impurities will enter the fracturing sand during the transportation process. The existing sand conveying device cannot filter the impurities in the sand, which affects the fracturing effect. Therefore, a continuous sand conveying device for fracturing sand pier is proposed.
