This application discloses a method for determining the inorganic scale damage rate, belonging to the field of oil and gas extraction. The method includes: pumping a displacement fluid into a first core and a second core, and determining the first permeability of the first core and the first permeability of the second core, respectively; pumping a mixed solution into the first core and the second core and allowing them to stand; determining the second permeability of the first core when the standing time reaches a first duration, and determining the second permeability of the second core when the standing time reaches a second duration; determining the damage rate of the first core and the damage rate of the second core, respectively; and determining the difference between the damage rates of the first core and the second core as the inorganic scale damage rate. This technical solution can decouple inorganic scale damage and water-sensitive damage by setting different standing times, thereby obtaining a more accurate inorganic scale damage rate and providing data support for assessing the degree of inorganic scale damage.

This invention discloses a self-expanding, temperature-resistant elastomer plugging agent for drilling fluids and its preparation method. The plugging agent is composed of the following components in parts by weight: 100 parts of temperature-resistant polyolefin elastomer matrix material, 5-20 parts of polymer composite modified water-absorbing reinforcing agent, 5-15 parts of carboxylated carbon nanotube-PEG water-absorbing reinforcing agent, 5-30 parts of reinforcing material, 10-30 parts of superabsorbent resin, and 0.5-1.5 parts of anti-hydrolysis agent. The plugging agent of this invention possesses excellent elasticity and a certain degree of toughness, allowing it to be squeezed into fractures under pressure. After absorbing water, its volume expands, yet it still maintains a certain degree of elasticity and strength. Under its own elasticity, it increases friction with the fracture surface, increasing the elasticity of the entire sealing layer, preventing the plugging material from flowing back or sliding deeper into the fracture, sealing the leakage channels, and achieving effective sealing of wellbore fractures.

The application belongs to the technical field of blow molding equipment, and particularly relates to a blow molding equipment for plastic product production, which comprises a supporting frame, a guide rod, a transplanting driving component, a sliding seat, a supporting guide rod, an opening and closing mold cylinder, a first forming mold, a second forming mold, a mounting platform, a material injection component and a pipe inserting and blowing component. In the application, the transplanting driving component drives the first forming mold and the second forming mold to move below the material injection component, and then the material injection component extrudes a tubular plastic embryo downwards. After the material injection is completed, the opening and closing mold cylinder drives the first forming mold and the second forming mold to close, the embryo is cut off and sealed in the process of closing, the transplanting driving component continues to drive to move below the pipe inserting and blowing component, the pipe inserting and blowing component is inserted into the embryo and blows air, and the embryo is inflated and formed in the mold forming cavity. Through the multi-station collaborative operation, the application realizes the automatic and continuous operation of material injection, mold closing, air blowing forming and mold opening and part taking, and effectively improves the production efficiency.

This invention belongs to the field of medical device technology and discloses a full-suture anchor system with an interlocking structure and a round flat suture band. The system includes: a full-suture anchor head, which is a circular tubular braided structure with a central cavity; a variable-diameter suture passing through the central cavity of the anchor head, the suture comprising a working section and a guide section, the guide section having a gradually tapering diameter; and a round flat suture band passing through the central cavity of the anchor head, the round flat suture band having circular braided structures at both ends and a flat band-like braided structure in the middle. Through the nested interlocking of the variable-diameter suture and the round flat suture band, parallel "suture bridge" structures can be formed between any anchors. By compressing the soft tissue, the gap between the avulsed soft tissue and bone is reduced, bringing it closer to its pre-avulsion state, which is beneficial for the regrowth and recovery of the soft tissue.
