摘要： A method for controlling the liquid load size of a plunger lift well during the shut in time of the well to facilitate a controlled plunger rise. Intra-cycle control allows dynamic adjustments within a cycle to keep the plunger running and not stalling out or rising too fast. The method includes the steps of shutting in the well to build up pressure within the well, adjusting a size of a liquid slug within the tubing while the well is shut in, opening a valve to relieve pressure within the well and raise the plunger within the tubing, pushing the liquid slug out of the well with the plunger, and closing the valve wherein the plunger falls within the tubing. The intra-cycle adjustments include reducing the size of the liquid slug for preventing fluid loading and increasing the size of the liquid slug for controlling a rise rate of the plunger.

摘要： An apparatus and method for controlling a well plunger system for the production of natural gas is described. The well plunger system includes a plunger tube positioned within a casing of a gas well, a tubing line connected to the plunger tube, a plunger moveable within the plunger tube, a plunger sensor for detecting the presence of the plunger, a valve connected to the tubing line and to the general gas distribution system including a sales line and a gas flow meter, a pressure sensor connected to the sales line, a motor for operating the valve, and a pressure sensor connected to the casing. The controller calculates the duration of an open interval when the valve is opened and a closed interval when the valve is closed based on a calculated average plunger velocity of the plunger after the valve is opened. The controller compensates for changes in sales line pressure by adjusting the calculated average plunger velocity by an amount equivalent to the changes in sales line pressure. After the calculated average plunger velocity is adjusted it is compared against a low velocity minimum and a high velocity maximum that define a desired operating range. If the calculated average plunger velocity falls outside of the desired operating range the controller increments or decrements the close interval by a fixed amount of time, compensating for changes in sales line pressure.
摘要翻译：描述了一种用于控制用于生产天然气的井柱系统的装置和方法。井柱系统包括位于气井的壳体内的柱塞管，连接到柱塞管的管线，可在柱塞管内移动的柱塞，用于检测柱塞的存在的柱塞传感器，连接到柱塞的阀管线和一般的气体分配系统，包括销售线和气体流量计，连接到销售线的压力传感器，用于操作阀的电动机和连接到壳体的压力传感器。控制器计算阀门打开时打开间隔的持续时间，以及阀关闭后基于计算出的阀门打开后柱塞的平均柱塞速度的闭合间隔。控制器通过将计算出的平均柱塞速度调整到相当于销售线压力变化的量来补偿销售线压力的变化。在计算出的平均柱塞速度后，将其与限定所需操作范围的低速度最小值和高速度最大值进行比较。如果计算出的平均柱塞速度超出所需的工作范围，控制器会将闭合间隔增加或减少固定的时间量，以补偿销售线路压力的变化。

摘要： A well has a wellbore extending from a surface. Tubing extends within the wellbore for supporting a downhole pump. Sucker rods extend within the tubing for reciprocating a travelling valve. A load calculator determines loading on the sucker rods during a pump cycle. A variable speed driver reciprocates the sucker rods and travelling valve. A real time speed controller varies a speed of the driver in response to loading information from the load calculator for smoothing the rod load in a beam pump cycle. A target rod load is obtained and a surface linear speed of rods is varied by either slowing or speeding a driver for varying a surface linear speed of the rods when rod loading is above or below the target rod load.

摘要： A pump for efficiently producing gas in wells having some liquids. The pump may be driven by a walking beam or horsehead pump. The pump of the invention produces gases and liquids separately. Gases may be produced up the annulus between the casing and hollow sucker rods. A plunger seals the opening in the cage during downstroke. Gases and liquids are trapped in the cage above an inner barrel. Liquids are forced up the hollow sucker rod where they are retained by a one-way valve. On the upstroke, the one-way valve seats and gases are forced out of the cage and up the annulus. Gases are, therefore, produced up the annulus and liquids are produced up the drill string. In another embodiment, liquids are retained in a trap and are produced up hollow sucker rods, while gases are produced up the annulus between the hollow sucker rods and the casing.

摘要： A work platform for oil drilling, oil production, or other purposes is constructed in arctic waters by locating a natural ice island of suitable area and thickness, and moving it to the desired platform location. The ice island is anchored to the sea floor by installing at least one, but preferably a number of, generally cylindrical sheaths beneath it which extend from the island to the sea floor below. The sheaths are filled with water, and a thermosiphon is installed interiorly of the sheath. As the thermosiphon extracts heat from the water within the sheath, the water is converted to ice, and eventually the entire body of water within the sheath is frozen, thereby forming a column of ice which anchors the island to the sea floor in the desired location.
