小井眼波动压力影响因素分析
AN ANALYSIS OF THE FACTORS INFLUENCING SURGE PRESSURE IN A SLIM HILE
摘要
Abstract
Surge pressure will be aroused in a conventional borehole,when a drilling string is moving in the well bore filled with drilling fluid,by which the pressure equalization in the borehole system will be destroyed,thus causing the complicated downhole circumstances and accidents as well blowout,lost circulation and well slough or drill-pipe sticking,etc.Owing to the fact that various flow path assemblages in hydraulic system have been changed in a slim hole,it is even more important to predict and control the surge pressure in the slim hole.In combination with an example of drilling slim hole,the influence of relevant factors on the surge pressure in the slim hole is quantitatively analyzed and the importance to strictly controlling the velocity of round trip in the slim hole is proposed in the paper.关键词
