山西临兴致密气钻井钻头优选及提效分析
Technology Supervision in Petroleum Industry（2021）
Abstract
针对临兴致密气钻井过程中井下漏失、溢流、缩径、掉块等复杂情况频繁发生,单趟钻进尺少,钻进速度慢,钻井周期长等问题,开展了对山西临兴致密气的地质特点、钻井过程中钻头选型和整体提速增效的研究.通过采用优化钻头选型、钻具组合和钻井液体系的提效措施,很大程度上提高了临兴致密气的单趟钻进尺和机械钻速,缩短了钻井周期,形成了针对临兴致密气钻井的钻头选型方案和提速技术,通过LX-4井和LX-8井的现场应用,钻井工期整体提效25.3％,具备推广应用价值.
