发明名称 APPARATUS AND METHOD FOR STRIPPING SOLIDS AND FLUIDS FROM A STRING USED IN DRILLING OR SERVICING WELLS
摘要 An apparatus and method is provided for stripping solids and fluids from a string used in the drilling or servicing of a well when the string is removed from the well. The apparatus can comprise two or more pivotally connected arcuate body portions that can be enclosed around the string in a clamshell fashion. The apparatus can further comprise a seal disposed therein to provide a toroidal sealing member around the string when the apparatus encloses the string. A quick release latch mechanism is provided on the apparatus for easy and quick installation on, and removal from, the string. Handles on the apparatus allow personnel to hold the apparatus in a stationary position as the string passes through the apparatus when being raised from the well. In so doing, the sealing member strips solids and fluids from the string.
