摘要
水力增压器不仅可以与水力压裂相结合,提高压裂效果,同时还可单独或与其他工艺相结合,用于油水井增产增注及新井投产,特别是对于不宜酸化解堵的酸敏地层和无法分层改造的多产层、薄油层来说,水力增压器更具推广应用的优势和前景。
Technology of pre-treatment by hydraulic booster before fracturing is pre-treatment of hydraulic impact to the reservoir to be fractured by hydraulic booster before fracturing job to create many radial micro-fractures near the wellbore,and hence improve the percolation there and reduce the fracture pressure in fracturing job,and enhance the fracture effect.Hydraulic booster can be used not only in fracturing job to enhance the fracture effect,but also in increasing production rate for oil wells or increasing injection rate for injection wells or put new wells into production by itself or combining with other techniques.Hydraulic booster has its especial advantage for acid-sensitive reservoirs for which acidizing is not good for removing blocking-up,reservoirs with multi-producing zones and thin reservoirs which can not be zonal-stimulated separately.
