摘要
在南中国海钻井过程中常遇到井眼偏斜、井眼净化、井径扩大和卡钻等问题。这些地区的许多问题是因台风停钻造成的。本文介绍了在最近完成的相当成功的钻井方案中消除这些问题的方法。用部分水解聚丙烯酰胺(PHPA)泥浆体系和最优化钻井方案来解决这些问题。
A partially— hydrolyzed polyacrylamide(PHPA) mud system and an optimized drilling program was used to offset drilling problems encountered while drilling in the South China Sea include deviated holes. The angle of deviation in this wells was great as 63 degrees from vertical with most wells having angles in the mid —40 degrees.
