| 总结: | Hydraulic fracturing is one of the effective methods of increasing the oil recovery of reservoirs. An important factor in hydraulic fracturing is the reliability of the packers, which are used to ensure the integrity of the production column. To prevent complications associated with tightness of casing pipes during hydraulic fracturing, studies were conducted to evaluate the methods of setting packers. After analyzing the practice of the application of packers, it was realized that five methods of setting them are used. The paper discusses the advantages and disadvantages of packer setting techniques. It is revealed, that the most reliable method is the combined version of setting of packers. The use of the combined setting method significantly increases the success of sealing the annular space of the well |
