FIELD APPLICATION OF SAND FRACTURING TECHNOLOGY IN THE PAD FOR SLANT WELL

Based on the problem of sanding out in early stage during hydraulic fracturing treatment,oil and gas wells have a high initial production,but decreasing fast,remaining production in short time and having lower total output,We have studied and applied the sand fracturing technology in the pad.The results show this technology increases the success ratio and effective rate.The technology have a broad prospects in hydraulic fracturing treatment.
