BOREHOLE STRESSED PACKER INFLATION SYSTEM BOREHOLE STRESSED PACKER INFLATION SYSTEM |
摘要 |
<p>A method for determining a proper inflation pressure for an elongated inflatable packer to effect a positive contact stress seal of an elastomer packer element with a borehole wall in a wellbore traversing earth formations. The temperature differential for each layer in a radial plane is determined. The final contact stress, the finite inflation pressure required to inflate the packer element and the temperature differential are functionally interrelated to on e another to obtain a final contact stress of the packer element with a borehole wall.</p> |
