摘要： A downhole pump has a barrel and a plunger movably disposed therein. The gap between the barrel and plunger has first and second seals. The barrel and plunger each have a one-way valve restricting fluid passage out of it. A filter or screen is disposed on the plunger between the first and second seals. In a downstroke, fluid and particulate in the barrel transfers into the plunger. In an upstroke, fluid and particulate in the plunger lifts uphole. At the same time, a volume in the barrel fills with fluid and particulate. During either stroke, the first seal prevents particulate uphole of the plunger from passing into the gap. The filter or screen, however, prevents at least some particulate (i.e., most or larger particulate) inside the plunger from passing out of the plunger with fluid flowing into the gap between the first and second seals.

摘要： A velocity string deploys in production tubing of a gas well (or a gassy oil well) to help lift fluid toward the surface. The velocity string reduces flow area in the production tubing so that a critical flow velocity can be reached to lift liquid. Overtime, the reservoir pressure and resulting gas flow may decrease such that less liquid is produced toward the surface. At such a stage, operators then expand the velocity string to further decrease the flow area in the production tubing, which can produce the needed critical flow velocity to allow produced liquid to be lifted toward the surface.

摘要： Oil is recovered from a borehole using a pump having limited high temperature breakdown resistance. The pump is located in a borehole having a cooling zone, in which the temperature of the well fluid is reduced to, or below, the temperature at which the temperature breakdown resistance of the pump is commercially acceptable. In one embodiment, the pump is a positive displacement pump which is mechanically driven from the well head location, such as through a rotating rod. The cooling zone is provided by positioning and controlling the pump to maintain a sufficiently low pressure at the pump intake to cause a portion of the liquid well fluid to vaporize prior to entry of the liquid into the pump, creating bubbles which pass upwardly in the wellbore in a zone passing the pump. The evolution of the vapor cools the well fluid to the acceptable temperature.

摘要： A de-watering pump is designed for eliminating liquids in small diameter holes. An expandable air sack is designed such that the outer walls of the air sack can expand to interface with the inner walls of the hole which is to be de-watered. Pressurized air is forced into the hole. The pressurized sack prevents the escape of air up through the hole and directs the pressurized air and water from the hole out through the escape line.
