无固相钻井液对保护油气层,提高采收率有着重要作用,并具有流变性好、携岩能力较强、有一定的护壁能力、抗污染能力强、密度低、有利于防漏、提高机械钻速和保护油气层等诸多优点。桩西古潜山深井施工中通过室内实验对待选钻井液处理剂进行抗高温老化优选,现场对钻井液处理剂进行复配,解决了无固相钻井液滤失量大等问题,满足了井下安全及优质高效钻进的要求,为区域钻井积累了经验。
Solid-free drilling fluid plays an important role in protecting oil and gas reservoirs and enhancing oil recovery. It has good rheological properties, strong rock carrying capacity, certain wall protection ability, strong anti-pollution ability, low density, which is good for leak prevention and improvement ROP and protection of oil and gas and many other advantages. In the deep pile construction of buried hill in Puxi, the drilling fluid treatment agent is selected for indoor heat treatment for anti-high-temperature aging optimization. The on-site drilling fluid treatment agent is mixed to solve the problem of no solid-phase drilling fluid filtration loss and the like, Safety and quality and efficient drilling requirements, has accumulated experience for drilling in the region.
