摘要:
針對塔河油田井壁不穩定地層,選取代表性泥頁巖巖心,通過X-射線衍射、掃描電鏡、膨脹、分散、比表面積、比親水量等試驗方法,進行了礦物組成、層理結構和理化性能分析,弄清了塔河油田井壁不穩定的主要原因,提出了有效的井壁穩定技術對策,優選出2套防塌鉆井液配方。現場試驗表明,2套防塌鉆井液配方均具有中途轉型順利、維護處理簡單、防塌效果突出等優點,使用該鉆井液體系可加快鉆井速度,節約鉆井綜合成本。
Abstract:
Because of its deeply embeded, complexity of geologic constructure, coexistence of defferent pressure layers, and so on, there are a lot of severity accident of well bore instability such as collapsing, lost circulation, hinderong and blocking in the formations of Triassic and Carboniferous in Tahe Oilfield. The mechanism of well bore instability was made clear through X-ray diffraction, Scanning Electron Microscope, swelling, shale dispersion, specific surface area and specific water wet amount of shale, analysised the mineral, stratum or stucture and physi-chemical performance on representative shale cones. The effective well bore stability technic-countermeasure were brought for ward, and 2 kinds of anti-sloughing drilling fluids were selected on this bases. The site trial indicate that the 2 kinds of anti-sloughing drilling fluids roll it’s hoop when be transfered in midway, simple in manage and maintenance, and effective in anti-collapsing, quickened the drilling velocity and saved integrated drilling cost.
