摘要
福山油田花场凹陷中深井构造地层复杂,花场凹陷流二段,流三段泥岩层理发育,易吸水膨胀、剥落掉块、垮塌,要适时调整泥浆密度、粘度、失水等性能,注意防卡,施工周期长,难度较大。本文选取HD-13x井为例,为今后福山油田深井优快钻井提供宝贵经验。
The middle and deep wells in the huachang sag of Fushan oilfield are complex,two depressions of the flower field and three stages of mudstone development,which are easy to absorb and expand,flake off the block and collapse.It is necessary to adjust the mud density,viscosity,water loss and so on in a timely manner,and pay attention to prevent card,long construction period and more difficult.This paper selects HD-13 x well as an example to provide valuable experience for the future deep well drilling in Fushan oilfield.
