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。
