An oil well blow-out preventer and sealing device for use on an oil well equipped with a well casing, a wellhead, a production tubing string, and a pump rod receivable within the production tubing string. The blow-out preventer and sealing device comprises a central housing member that includes a flow passageway and a pump rod passageway, blow-out prevention means and pump rod passageway sealing means, both contained within the central housing member. The flow passageway is in communication with the production tubing string and provides a means for fluid to be removed from the well while the pump rod passageway provides a means for entry of the pump rod into the well. The blow-out prevention means includes a pair of rams that are adjustable to seal around the pump rod to prevent the accidental loss or spillage of oil or fluid from the well. The pump rod passageway sealing means prevents the spillage of fluids from the oil well upon the breakage or removal of the pump rod from said pump rod passageway.

Bloc d'obturation de puits et dispositif de scellement dans un puits équipé d'un cuvelage, d'une tête de puits, d'un train de tubes de production et d'une tige de pompage qui se loge dans le train de tubes de production. Le bloc d'obturation de puits et le dispositif de scellement comprennent un boîtier central qui comporte un passage pour l'écoulement du fluide et un passage pour la tige de pompage, un mécanisme d'obturation de puits et un dispositif de scellement du passage pour la tige de pompage, qui sont tous deux contenus dans le boîtier central. Le passage pour l'écoulement du fluide communique avec le train de tubes de production et offre un moyen d'enlever le fluide du puits, alors que le passage pour la tige de pompage comporte une ouverture pour l'entrée de la tige de pompage dans le puits. Le mécanisme d'obturation de puits comprend deux mâchoires réglables de manière à former un joint étanche autour de la tige de pompage, afin d'éviter la perte ou le déversement accidentel de pétrole ou de fluide provenant du puits. Le dispositif de scellement du passage pour la tige de pompage empêche le déversement de fluides provenant du puits de pétrole en cas de bris ou d'enlèvement de la tige de pompage du passage de cette dernière.
