Title: Shenglai Guo: Innovator in Well Cementation Technologies
Introduction
Shenglai Guo is a prominent inventor based in Qingdao, China. He has made significant contributions to the field of well cementation technologies, holding a total of 9 patents. His innovative work focuses on developing materials and methods that enhance the efficiency and safety of oil and gas exploitation.
Latest Patents
One of his latest patents is a sealing gel with delayed gelation for well cementation. This invention includes a specific formulation comprising 2-3 parts of anionic polyacrylamide, 3-4 parts of cationic acrylamide, 1 part of stabilizer, 1 part of cross-linking agent, and 6 parts of distilled water. The stabilizer is created through a reaction involving citric acid and ethylenediaminetetraacetic acid disodium, while the cross-linking agent is derived from chromium lactate and chromium nicotinate. This sealing gel is designed to have pH sensitivity, which prolongs the gelation time, allowing it to be effectively added to the pre-liquid system for well cementation.
Another notable patent is for an anti-corrosion and low-heat-conduction annulus protection fluid for deep-sea oil and gas exploitation. This fluid consists of a polymer solution, clear water, a thermally-insulating material, a corrosion inhibitor, and xanthan gum. The polymer solution is a mixture of a polymer and clear water in a specific mass ratio. This innovative fluid exhibits excellent thermal insulation performance and corrosion resistance, preventing the generation of hydrates and the decomposition of hydrate layers at the wellhead.
