Drilling optimization design and application effect of Well Dawang Tancai 1 in Xiong'an New Area

Abstract

Xiong'an New Area is an area with the most abundant geothermal resources and the best conditions for development and utilization in eastern China. The full use of geothermal resources is of great significance to the future construction of a green and low-carbon city in Xiong'an New Area. Xiong'an New Area is rich in geothermal resources, which can meet the construction area of about 100 million square meters in the future. This paper mainly introduces the research content and field application effect of the drilling design of Well Dawang Tancai 1 deployed in the Xiong'an New Area. In view of the main risks faced by regional drilling, the optimization design research was carried out from the aspects of geological overview, well structure, drilling parameter optimization, drilling fluid technology and cementing technology, and field applications were carried out to achieve good results and form a geothermal well drilling supporting technology. Provide technical support for the development and utilization of geothermal resources in Xiong'an New Area.
