摘要
南海西部油田文昌13区ZJ1-3油组具有低渗、高泥质的储层特性,增产改造所需规模较大,用淡水配制压裂液无法满足连续在线配液和压裂施工规模的要求。针对此问题,展开海水配置压裂液的技术攻关。运用新型交联技术,克服了高矿化度下瓜胶水化增黏、pH值控制、携砂等困难,并保证了压裂液的速溶性。在现场应用中采用连续混配的方法,成功实施了平台规模化的分段压裂。
According to the reservoir characteristics （low permeability and high mud content） of ZJ1 -3 oil field, Wenchang 13 district in the western South China Sea, the transformation of the scale is large, but the fresh water fracturing fluid preparation cannot realize on - line liquid mixing construction. Through indoor research, we carried out many experiments about the technology of fracturing fluid in seawater. By using new crosslinking technology, we overcome the difficulties achieve instant fluid. In on platform scale of glue viscosity increasing under high salinity, pH value control and sand - carrying to - site operation we adopt continuous mixed method to implement the staged fracturing of
