Plugging thixotropic cement paste for oil-gas well and preparation method for same

The invention relates to a plugging thixotropic cement paste for an oil-gas well and a preparation method for the same. The plugging thixotropic cement paste is composed of the following constituents in parts by weight: 100 parts of oil-gas cement, 0.5-10 parts of a thixotropic agent, 0-200 parts of a density regulator, 0-35 parts of a stabilizer, 0-6 parts of a coagulation time regulator, 0-5 parts of an expander, 0.5-3 parts of a dispersant, 0-2 parts of a defoamer, and 60-150 parts of water. Via the plugging thixotropic cement paste disclosed by the invention, the technical problem of loss during the well construction process and the production process of the oil-gas well can be effectively solved on the premise of meeting the various engineering performances needed by the plugging cement paste for the oil-gas well, thus providing a guarantee on the subsequent drilling and completion as well as the safety production of the oil-gas well.
