摘　　要：以宝浪油田宝北区块低孔、低渗油藏实钻的 2口水平采油井为例 ,分析了 2口水平井的整个实施过程 ;总结了油藏筛选、产能预测、井网部署、钻 (完 )井技术、油层保护、动态分析等几个关键环节的经验和教训。通过分析基本摸清了水平井技术特点 ,以避免在推广应用水平井过程中出现失误 ,以改善低渗透油藏水平井开发效果 ,提高经济效益。This paper summarizes experiences in reservoir screening, productivity forecast, well pattern deployment, drilling (completion) technique, reservoir protection and performance analysis based on analysis of two horizontal production wells of low porosity and low permeability in Baobei block, Baolang oilfield. This helps avoid mistakes during the applications of horizontal wells, improve horizontal well development effect in low permeability reservoirs and increase economic benefit.
