摘要

川东池浅1井T1j12气层H2S含量很高,现不能开采;T1j12气层H2S含量较低,可以开采。两个气层相距20m,极易串通,所以固井质量很重要。为此,使用了川石·克里斯坦森金刚石钻头有限公司生产的?149mm金刚石双心全面钻进钻头和?151mm金刚石双心取心钻头,井眼扩大值分别为19mm和11mm,

Abstract

Chiqian 1 well,in eastern Sichuan oilfield,T1j12 gas pay zone has high content of H2S that can’t be developed now,but T1j12 gas zone which has low content H2S can be produced.Tow zones pace 20 m and is easy channeling,so cement quality is important to development.To solve this problem,149mm diamond dual centers drilling bit and 152mm diamond coring bit are used and hole diameter increased by 19mm and 11mm separately.Over-cut rate are 12.8% and 7.3% separately,for cement quality created reliable condition.
