Bottom water reservoir fracturing method adopting water-deformable propping agent to control water breakthrough

The invention belongs to the technical field of oil production engineering and particularly relates to a bottom water reservoir fracturing method adopting a water-deformable propping agent to control water breakthrough. The bottom water reservoir fracturing method comprises the steps that 1, perforation is performed at the top position of a bottom water reservoir; 2, fracturing construction begins, an oil-based fracturing fluid is used as an ahead fluid to be injected into a stratum to cause crack initiation and make artificial fracture; 3, the oil-based fracturing fluid is adopted to carry the propping agent to flow into the stratum, wherein the propping agent does not change when encountering oil but is softened and produces deformation and solidification when encountering water; 4, the propping agent is softened and produces deformation and solidification to form a high-strength penetration-free blocking layer when encountering water in the fracturing construction process; 5, an oil-based fracturing fluid base fluid is used for replacing a sand-carrying fluid to flow into the stratum, wherein the using amount of the base fluid for replacement is equivalent to the volume of an operating tool string; 6, well shutdown is performed for 60 minutes, and blowout and production are performed. By the adoption of the bottom water reservoir fracturing method, the problem that existing cracks downwards extend to be communicated with bottom water, the blocking capability of an oil-water layer interface is improved through the water-deformable propping agent, and upward bottom water breakthrough is controlled.

Left Atrial Appendage Occluder

A left atrial appendage occluder (200) comprises a sealing part (220), a fixing part (210) disposed at one side of the sealing part (220), and a connection part (230) for connecting the sealing part (220) and the fixing part (210). The radial deformation capacity of the sealing part (220) is greater than the radial deformation capacity of the fixing part (210), and/or, the axial deformation capacity of the sealing part (220) is greater than the axial deformation capacity of the fixing part (210). In the left atrial appendage occluder (200), the radial or axial deformation capacity of the sealing part (220) is configured to be greater than the radial or axial deformation capacity of the fixing part (210), thereby avoiding the situation in which the sealing part (220) is not optimally fitted with the opening of the left atrial appendage (10) when the fixing part (210) is placed inside of the left atrial appendage (10), which in turn enhances the occlusion effect. Additionally, the sealing part (220) has great deformation capacity which reduces the risks of the sealing part (220) causing abrasion to the opening of the left atrial appendage, or even damaging the opening of the left atrial appendage. The fixing part (210) not only avoids the risks but also fixes the occluder in the left atrial appendage (10) more effectively, and prevents the occluder (200) from being disengaged from the left atrial appendage.
