Description

[0002] With the development of oil exploration and development, the drilling depth continues to increase, the formations encountered are becoming more and more complex, and the number of special process wells such as directional wells and horizontal wells is gradually increasing, all of which put forward higher requirements for drilling fluid treatment agents. Especially in drilling operations, strong water-sensitive formations are often encountered, which can easily cause complex problems such as drill bit mud packing, well wall collapse, well diameter reduction, and drill bit jamming, all of which have a great impact on drilling safety. Therefore, drilling fluid will be injected into the well for protection, which can effectively inhibit the hydration expansion and dispersion of shale, fill the cracks in the well wall, and play a role in stabilizing the well wall. At present, pipelines are mainly used to transport drilling fluid to the designated location, but drilling fluid is often mixed with additives such as asphalt according to the use requirements. In areas with lower temperatures, it will affect the smoothness of the flow of drilling fluid in the pipeline, making it inconvenient to transport it over long distances. Utility Model Content
