摘要： The present invention relates to a mandrel for a gas lift valve which comprises an elongated body provided with means of connection at its ends. The body is provided with a side pocket (17) and a side receptacle (16) in the interior of which may be housed a gas lift valve (13) which injects gas into the interior of the body of the mandrel for the gas lift valve (15) by means of orifices (22) positioned in a nose (18). The mandrel for the gas lift valve (15) comprises additionally a lower body (23) provided on the lower part of the valve receptacle (16) of the mandrel of the side pocket (15) in that the lower body (23) is configured in a manner to seal the lower part of the valve receptacle (16) to form a chamber (24) and the lower body is provided with at least one injection orifice to inject gas into the interior of the body of the mandrel of the gas lift valve (15).

摘要： The present invention relates to a method and a device to stabilize the production of oil wells. The device is used in a tubing of an oil well and it is intended to overcome the harmful effects provoked by the unstable flow of multiphase flows which are produced by some oil wells. In an oil well producing by means of continuous gas lift a device is installed into the tubing, said device being provided with a first portion, which provides a progressive constraint in the area for the passage of the flow coming from the reservoir, a second medium portion, located above the first portion, located above the first portion, which makes said area for the passage of the flow coming from the reservoir to be substantially constant at this point and smaller than the original area of the tubing, and a third upper portion, located above the second medium portion, which provokes a progressive widening in said area for the passage of the flow coming from the reservoir, until such area for the passage of the flow is again equal to the original area of the tubing. Such device can be located in front of the gas lift valve through which the injection gas is injected.

摘要： A method to set a hollow device into an undersea flow pipe uses a flexible pig driven by a flow flowing into said flow pipe to displace a hollow device to a point where a stop means halts a displacement of said hollow device, thereby setting said hollow device into position. A method to retrieve a hollow device into an undersea flow pipe uses a flexible pig driven by a flow flowing into said flow pipe to retrieve said hollow device from a location where said hollow device operates halted by a stopping means.

摘要： An apparatus uses at least one injection pump (9) positioned in proximity to an undersea petroleum well (10) to provide hydraulic fluid for hydraulic pumping equipment positioned in the bottom of the well, in order to cause a flow of produced oil. The injection pump (9) is able to suction hydraulic fluid from a tank of hydraulic fluid (8) positioned on the deck of a service unit (40). Alternatively, injection pump (9) is able to utilize water from the sea as a hydraulic fluid. Alternatively, the injection pump (9) may be integral with a Christmas tree manifold (6) or may be installed in an auxiliary well (90) in order that it's external portion does not enter into contact with seawater.
