Abstract
In order to solve the problems faced by 8000m class drilling and completion in tarim Basin, such as high temperature, high pressure, complicated formation, low bearing capacity of Permian tuff and development of fractures and pores in basalt segment, etc. Combined with the actual construction situation, has formed the basin area of 8000 m class drilling and well completion key technology optimization results, including optimization of casing program design and matching high crowded outside casing strength, super light corrosion resistance of titanium alloy pipe, under different working condition of the high strength developeded. These technologies, new anti-gas channeling resistance to high temperature high density cement slurry system in sectors such as advanced and practical technology. The successful application of the technology system in the 8000m class drilling in the Platform basin area has greatly boosted the exploration and development process of deep oil and gas resources, and helped improve the competitiveness of the drilling and completion market in China.
