摘　　要：哈萨克斯坦盐下油层埋藏深(垂深4 500 m左右),地质条件复杂,下二叠系和石碳系层系压力极高,泥板岩钻时极低,在井下事故预防及提速两方面存在挑战。本文以KJ-HW8井为例,讲述该区域轨迹控制、安全措施制定等钻井方案。Oil reservoirs in Kazakhstan are buried deeply （TVD about 4 500 m） ,and geological conditions are very complex, with high pressure between two layers of Permian and Carboniferous. Drilling in the lower fender rock is very slow. There are challenges in both accident prevention and speed improvement. In this paper, taking KJ-HW8 well as example, the drilling plan including trajectory control and safety assurance was discussed.
