摘要
川西致密储层垂向渗透率远小于水平渗透率,水平井自然产能与直井相比无明显优势,水平井需要采取增产改造措施。为此川西气田开展了包括笼统酸化、笼统压裂、分段压裂等水平井储层增产改造措施。同时为解决井筒积液难题,开展了水平井泡沫排水、车载压缩机气举排水增产工艺探索。
Since vertical permeability is much smaller than level permeability in the western Sichuan tight reservoir,the natural productivity of horizontal wells has no obvious advantage compared with vertical wells.Horizontal wells require stimulation measures.So general acidification,general fracturing,sub-fracturing are implemented on horizontal wells of the western Sichuan gas field and other reform measures to increase the reservoir,horizontal wells yield a significant effect of stimulation.At the same time,horizontal wells accumulate fluid in wellbore is a common problem.In order to solve this problem,the western Sichuan gas field carries out foam drainage and gas lift fluid by board compressor in horizontal well.
