摘要： A system is provided that monitors at the wellsite injection of additives into formation fluids recovered through wellbores and controls the supply of such additives from remote locations. A pump supplies the selected additive from a source at the wellsite into the wellbore via a suitable supply line. A flow meter in the supply line measures the flow rate of the additive through the supply line and generates signals representative of the flow rate. A controller at the wellsite determines the flow rate from the flow meter signals and in response thereto controls the pump to control the flow rate of the additive to the well. The wellsite controller interfaces with a suitable two-way communication link and transmits signals and data representative of the flow rate, and other parameters to a second remote controller. The remote controller transmits command signals to the wellsite controller representative of any change desired for the flow rate. The wellsite controller is microprocessor based and may be programmed at the wellsite or by the remote controller to adjust the flow rate. The system of the present invention may be configured for multiple wells, with each well having a separate wellsite controller or a common wellsite controller.

摘要： A system for monitoring foaming or carry over, at a well site, of a formation fluid by taking a sample of the gas exiting from a high-pressure separator and either measuring the density of the sample or measuring the amount of oil particles present. A correlation of the density or optical density with a level of foaming is made and a signal is transmitted to a device to control the supply of at least one additive to control the foaming.

摘要： The present invention provides a system and method for in-situ monitoring of corrosion in a conduit which carries fluids that have corrosive effects on the materials utilized for the conduit and/or equipment disposed in the conduit. The conduit may include a well carrying hydrocarbons from subsurface formations or a pipeline transporting hydrocarbons. A cable of sufficient length having a conductor that is susceptible to the corrosive effects of the fluids in the conduit is deployed along a length of the conduit. The conductor is exposed to the fluid continuously or at selected spaced apart locations. The distance of each of the exposed locations from an accessible end is known. A signal generator coupled to the cable induces a pulsed signal into the cable. The transmitted signals are reflected by location on the cable where the impedance differs from the normal impedance. Such locations include each of the exposed conductor locations and the termination point. The reflected signals are received by a receiver and then processed and analyzed by a processor to determine the extent of the corrosion at each of the exposed locations. This information is then used to estimate the nature and extent of the corrosion of components in the wellbore or the pipeline, as the case may be. The cable may be a single conductor cable or a twisted pair of wires, each having a known impedance per unit length.
摘要翻译：本发明提供了一种用于原位监测导管中的腐蚀的系统和方法，该导管承载对用于设置在导管中的导管和/或设备的材料具有腐蚀性影响的流体。导管可以包括从地下地层或输送烃的管道输送烃。具有导体的足够长度的电缆易于受到管道中的流体的腐蚀影响，沿导管的一段长度展开。导体连续地或在选定的间隔开的位置暴露于流体。每个暴露位置与可访问端的距离是已知的。耦合到电缆的信号发生器将脉冲信号引入电缆。传输的信号由电缆上的阻抗与正常阻抗不同的位置反射。这些位置包括每个露出的导体位置和终止点。反射信号由接收器接收，然后由处理器进行处理和分析，以确定每个暴露位置处的腐蚀程度。然后将该信息用于估计井眼或管道中部件腐蚀的性质和程度（视具体情况而定）。电缆可以是单根导体电缆或双绞线，其每个具有每单位长度的已知阻抗。

摘要： A chemical injection pump for injecting chemicals into subsea system at depths up to 10,000 feet is described which uses a minimum of moving parts by employing an actuator, for instance a solenoid, to power a double acting actuator rod and plungers thereon. The pump would generate low pressures and low fluid volumes, but be more durable and reliable than conventional rotating pumps operating under subsea conditions.
