影响液动旋冲工具井斜的因素及参数优化

Well Deviation Impacting Factors and Parameters Optimization of Hydraulic Rotary Percussion Tool

液动旋冲工具是一种新型的钻井提速工具,钻井效率高,但由于区块地质条件复杂,部分井段出现井斜角难以控制的现象,制约了工具的推广应用。应用Landmark软件对影响井斜的因素进行分析,优选钻具组合及施工参数,并在莺深6井进行应用,取得良好的效果。

=As being a new drilling tool, hydraulic rotary percussion tool can increase drilling ability significantly. But some wells have an excess of deviation angle, restraint the using of the tool. To avoid borehole inclination, Landmark is used to analyze the reasons of borehole inclination ele ments,optimize drilling parameters and combination of drill tool, and achieve positive effect in Yingsheng well.
