1) safe density window
安全密度窗口
2) 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。
3) mud weight range
安全泥浆密度窗口
5) Safe weigh window of drilling fluids
钻井液安全密度窗口
6) The secure window of mud density
泥浆密度安全窗
