【摘要】 近年来通过大力进行外围勘探,中石化西北油田分公司相继在玉北等地区实现了油气突破。但是外围地区地质条件复杂,高压盐水层、膏泥岩发育,在钻井中遇到了诸如井壁失稳、套管变形等复杂情况,导致探井成井慢,影响了勘探开发的步伐。文章针对前期钻井实践,全面系统总结了玉北地区的钻井难点,并提出了针对性技术对策。更多还原

【Abstract】 The geological conditions of Yubei area are complex,have large numbers of high pressure salaquifer and gyprock,more drilling engineering problems such as borehole instability,casing deformation etc.lead to a long drilling cycle.By analyzing drilling problems in Yubei area,this paper proposed pertinence solutions,which has a guide meaning for the exploration and drilling in this area.更多还原
