1) Safe weigh window of drilling fluids
钻井液安全密度窗口
3) safe mud density window
安全钻井液密度
1.
Based on the comprehensive analysis of logging data,geological information and laboratory tests results,this paper studied the pore pressure,in-situ stresses and rock strength of Liuhua 11-1 oil field,analyzed the borehole stability during the drilling of shale and limestone payzones for extended-reach wells,and calculated the safe mud density window for the extended-reach wells.
在此基础上定量分析了该油田在超大位移井钻井过程中泥页岩地层和灰岩储层的井壁稳定性,并得出了地层破裂压力、坍塌压力随井斜角和方位角的风险分布规律以及安全钻井液密度窗口。
5) safety density window
安全密度窗口
1.
Because carbonate rock in Carboniferous system which was main reservoirs develop many cracks that caused not only mud loss but also well kick,and had narrow safety density window of drilling fluid,first lost circulation then well blowout is easily to happened,so drilling fluid rheological property became as the important factor of affecting pressure balance in well.
94,裂缝发育,漏喷同层,钻井液安全密度窗口窄,极易出现先漏后喷的复杂局面,钻井液流变性成为影响井下压力平衡的重要因素。
6) safe density window
安全密度窗口
补充资料：饱和盐水钻井液
分子式：
CAS号：
性质： 一种水基钻井液，氯化钠在其中的浓度达到了饱和程度，即一般情况下氯离子浓度约为189000mg/L。
