摘要
Abstract
Drilling difficulties in deep buried hill wells in Jizhong depression of Huabei Oilfield mainly behave as wall crash down, bit freezing, leak off, low drilling rate, well deviation, and so on. To solve the problem of leak and crash down coexisting, different settlements were adopted, such as well structure optimization, special drilling for certain leaking layer, under-balanced drilling with low density water-in- white oil drilling fluid system, etc. Different sealing measures were taken for various types of leak type and they were successfully applied in the oilfield practice. Considering the features of mudstone in buried hill in Cambrian and the formation of Tertiary, low density water-in-oil drilling fluid, high density oil-in-water drilling fluid and poly-silicon fluoride drilling fluid system with strong rejection capability can be used.关键词
