以辽阳红阳煤田徐往子井田为研究区,探讨了该区U形井剖面设计方法的选择及施工工艺的设计。通过对储层特征的研究,设计水平段方位沿煤层倾向方向,对比分析了单增剖面和双增剖面轨迹设计优缺点,选择了双增剖面设计U形井轨迹;设计了三开井身结构,通过施工,轨迹施工效果良好,成功连通两井。 Taking Xuchangzi minefield in Hongyang coalfield of Liaoyang as the research area, the design method of the U-shaped section design and the design of the construction technology are discussed. Through the study of reservoir characteristics, the orientation of the horizontal section along the direction of coal seam is designed. The advantages and disadvantages of single-section and double-section profile trajectory design are compared and analyzed. The dual-section design of U-shaped well trajectory is selected. Through the construction, the track construction works well and the two wells are successfully connected.
