头台油田目前已进入生产开发的中后期,随着稳产增产形势的加剧,水平井及进行水平井压裂工艺已经成为公司的一项主要技术攻关方向。2010年头台油田进行了台13-平21水平井压裂工艺研究,台13-平21水平井采用动态胶塞封堵微裂缝技术和水平井双封单卡技术,并对压裂方案进行个性化设计:压前加酸处理(每压裂层段加酸2m3),以低砂比进行加砂,并降低前置液排量。
The Toutai oilfield has entered the middle and late stages of production and development. With the steady increase in output and the intensification of the production situation, horizontal wells and horizontal well fracturing have become one of the key technological breakthroughs of the Company. In 2010, Tietai Oilfield conducted a research on the fracturing technology of the 13-Ping-21 horizontal well. In the 13-Ping-21 horizontal well, the technology of dynamic rubber plug plugging micro-fracturing technology and horizontal well double-seal single-card technology was applied. Design: Pre-pressure acid treatment (acidification per fracturing zone 2m3), sand with low sand ratio, and reduce the displacement of the fluid.
