Many factors can influence stability of well wall in the area of petroleum drilling engineering.

在石油钻井工程中，影响井壁稳定性的因素较多。

Contrarily,if the stress of the wellbole is more than the rock strength,the wellbore will not be in stability. As the pressure of air drilling is so small that the pressure of well pit can not balance the layer pressure when the wellbore formated, and the stability of wellbore only depends on the rocks nature strength.

由于空气钻井过程中井筒内产生的压力很小，井眼形成后，井筒内压力无法平衡地层产生的应力，井壁是否稳定主要取决于岩石本身固有的强度性质。

In this paper,research on wellhead system stability of offshore oil self-elevating drilling platform exploratory well is introduced,the matching equipment technology and operation points such as wellhead casing head ,offshore water isolation tube,mudline suspension flow,wellhead suspensi.

The results show that the vibration intensity of the substructure has a connection with the depth of the well, the geological condition and the density of drilling fluid; the horizontal vibration of the substructure is mainly caused by bent kelly; the included angle between the axis of cardan shaft and the derrick floor is also the cause of the vibration in three directions, and the cause of t...

分析结果表明，底座的振动强度与井深、地质条件和钻井液密度有关；弯曲的方钻杆是造成底座水平方向振动的最主要原因；万向轴因与钻台面存在夹角，从而引起底座在三个方向的振动；采用四挡钻进时，万向轴的工频及其倍频接近底座垂直方向的固有频率是引起底座在该方向振动强烈的原因。

Because of dipping bed during drilling process,the wellhead crossed trace of well is no longer vertical line,but is the spatial curve,which resulted in deviation of first break time used by cross hole tomographic calculation,affecting the imaging precision.

在钻井过程中由于地层倾斜等原因，导致井的轨迹不是过井口的垂线，而是一条空间曲线，这就造成井间地震成像计算所用的初至旅行时存在偏差，影响成像精度。
