A kind of recyclable anti-collapse polymer mud and preparation method thereof

technical field

The invention relates to the technical field of pile foundation wall protection mud, in particular to a recyclable anti-collapse polymer mud and a preparation method thereof.

Background technique

During the drilling construction process, many problems caused by the instability of the wellbore caused by water-sensitive geological water absorption and hydration and dispersion, such as reducing the diameter of the wellbore, collapsing, jamming the pipeline, and even causing the drilling damage process, will not only bring economic losses, It will also lead to safety hazards. Therefore, it is very necessary to choose drilling fluid reasonably. Oil-based drilling fluid is always the best choice to alleviate the problem of wellbore instability, but its widespread use is limited due to its high cost and serious environmental damage. Therefore, it is an inevitable trend to gradually replace oil-based drilling fluids with water-based drilling fluids with properties similar to those of oil-based drilling fluids. However, traditional water-based drilling fluids have a strong ability to erode water-sensitive formations. When water-sensitive geology with a large amount of clay (such as shale, etc.) Moisture is absorbed in the drilling fluid, and because of the unique chemical properties of shale, this can lead to rapid swelling or dispersion of the shale, which can pose major safety concerns for drilling operations.

Clay is an important part of most water-sensitive geology, and clay swelling occurs when encountering the filtrate of water-based drilling fluid, which may be the most fundamental cause of wellbore instability. Therefore, reducing clay swelling is the key to preventing wellbore instability. In recent years, various materials have been used to modify water-based drilling fluids in the process of drilling in water-sensitive geology to achieve the purpose of preventing the expansion of clay minerals, and the most common method to minimize clay expansion is to use plugging in drilling fluids material or inhibitor. Plugging materials in water-based drilling fluids, such as ultra-fine calcium carbonate and elastic particles, can form a thin solid layer to reduce water invasion to a certain extent. And with the development of science and technology, the application of nanomaterials in reducing the instability of the wellbore is also increasing, among which shale inhibitors, such as KCl, gelatin, polymers, etc., are widely used in drilling fluids to reduce the instability near the wellbore. Clay swells. However, if plugging materials or shale inhibitors are used alone, the effect cannot meet expectations, so plugging materials and shale inhibitors are generally used in combination. Although the current research on water-based drilling fluids has achieved many results, However, the wellbore instability caused by clay expansion still faces great challenges in drilling complex formations, so it is urgent to develop new water-based anti-slump drilling fluids; and in the process of mud preparation, it is not convenient to adjust the height of the transport components And the width of the conveying track is adjusted.
