A geothermal well system can include a tubular string disposed in a production wellbore, the tubular string including at least one valve, water which flows from an injection wellbore into a formation surrounding the wellbore, and then flows from the formation into the production wellbore as steam, and resistance to flow through the valve decreasing automatically in response to presence of the steam in the production wellbore. Another method of geothermal energy production can include injecting water into a formation from an injection wellbore, the water changing phase in the formation, and then automatically decreasing resistance to fluid flow through at least one valve in response to presence of steam in a production wellbore.

摘要： A well system includes a main wellbore extending from a terranean surface toward a subterranean zone. A first lateral wellbore extends from the main wellbore into the subterranean zone. A second lateral wellbore extends from the main wellbore into the subterranean zone. A liner junction device resides in the main wellbore and has a first leg extending into the first lateral wellbore and a second leg extending downhole in the main wellbore. A treatment fluid injection string extends from in the main wellbore through the liner junction and into the first lateral wellbore and terminates in the first lateral wellbore. A seal in the first lateral wellbore seals against flow toward the main wellbore in an annulus adjacent an outer surface of the treatment fluid injection string.

摘要： A hydraulic jar for delivering impacts downhole. The jarring mechanism includes a cup-type piston that moves through a seal bore. The cup is deformable in response to fluid pressure so that it expands each time it moves through the seal bore to compensate for wear on the lip. Since only minimum interference is required between the piston and seal bore, less material may be used. This reduces the force required to reset the tool, which is particularly advantageous in horizontal wells. The seal bore may be slightly wider at the exit; the cup expands to this exit diameter, ensuring an interference fit as the cup travels back through the smaller diameter entry section. The entry end of the seal bore may include longitudinal grooves. This prevents the piston cup from rupturing by preventing a fluid seal around the lip until the most of cup is inside the seal bore.
摘要翻译： 用于在井下输送冲击的液压罐。 振动机构包括移动穿过密封孔的杯形活塞。 杯子响应于流体压力而变形，使得其每次穿过密封孔时都会膨胀，以补偿唇缘上的磨损。 由于在活塞和密封孔之间只需要最小的干扰，所以可以使用更少的材料。 这减少了重置工具所需的力，这在水平井中是特别有利的。 密封孔可以在出口处稍宽一些; 杯子膨胀到该出口直径，确保当杯子通过较小直径入口部分返回时过盈配合。 密封孔的进入端可以包括纵向凹槽。 这防止活塞杯通过防止围绕唇缘的流体密封而破裂，直到杯的大部分位于密封孔内。

摘要： A fluidic oscillator can include an input, first and second outputs on opposite sides of a longitudinal axis of the oscillator, whereby a majority of fluid which flows through the oscillator exits the oscillator alternately via the first and second outputs, first and second paths from the input to the respective first and second outputs, and wherein the first and second paths cross each other between the input and the respective first and second outputs. Another oscillator can include an input, first and second outputs, whereby a majority of fluid flowing through the fluidic oscillator exits the oscillator alternately via the first and second outputs, first and second paths from the input to the respective first and second outputs, and a feedback path which intersects the first path, whereby reduced pressure in the feedback path influences the majority of fluid to flow via the second path.
