水平井技术适用于薄层油藏、天然裂缝油藏、存在底水锥进的气藏中,当前,该项技术常规钻井技术应用于裂缝性碳酸盐岩、页岩、砂岩地层,有效开发枯竭油藏、致密气藏等所有类型的油藏,并且还涌现了部分新的应用趋势:水平井作为注入井,增强产量;分支水平井开采多个产层;水平井资料用于油藏描述;开采老油田剩余油;等等。笔者根据自身工作经验,首先对水平井采油工艺现状进行了分析,其次,指出了水平井采油工艺的发展趋势。
Horizontal well technology is suitable for thin-layer reservoirs, natural fractured reservoirs, and gas pools with bottom water coning. Currently, this technology is applied to fractured carbonate, shale and sandstone reservoirs and is effectively developed Depleted reservoirs, tight gas reservoirs, and some other types of reservoirs, and some new trends have also emerged: horizontal wells as injection wells to enhance production; multiple horizontal wells for production; horizontal well data for reservoir description ; Exploitation of remaining oil in old fields; Based on my own working experience, the author first analyzes the status quo of horizontal well production process and secondly, it points out the development trend of horizontal well production process.
