High-temperature-resistant produced liquid sediment profile control water plugging agent and preparation method thereof

The invention relates to the technical field of oil exploitation, in particular to a high-temperature-resistant produced liquid sediment profile control water plugging agent and a preparation method thereof. The invention relates to a high-temperature-resistant produced liquid sediment profile control water plugging agent, which comprises the following components by weight: 25-55% of a temperature-resistant main agent; 2.5%-11% of a curing agent; 0.2%-0.3% of a temperature-resistant polymer component; 0.1%-0.3% of a suspension regulator; 20%-30% of a reinforcing agent; and the balance of water. The invention relates to a preparation method of a high-temperature-resistant produced liquid sediment profile control and water plugging agent, which comprises the following steps: sequentially adding a formula amount of temperature-resistant polymer component and a formula amount of suspension regulator into a formula amount of water, stirring for 30-60 minutes until the components are swelled, sequentially adding a
