摘要： An oil well tool for in situ release of treatment fluid into an oil well is disclosed. A tubular body is insertable into an oil well casing, which tubular body carries a bladder containing treatment fluid. The body is closed at a lower end and has at an upper end a fishing neck connector. A weight slideable within the tubular body compresses the treatment fluid within the bladder and forces the treatment fluid under a constant pressure through a fluid passageway. The size and length of the fluid passageway, combined with the pressure applied and viscosity of the treatment fluid, dictate the flow rate at which the treatment fluid is deposited into the oil well. The treatment fluid mixes with other fluids being circulated through the well formation. The primary purpose for the treatment fluid is to inhibit scale buildup and corrosion. This is accomplished by slow release of the treatment fluid over an extended period of time.

摘要： The invention provides a system and method measuring high and low fluid velocity in well bores and particularly for fluids exhibiting stirring action. The system and method (300) includes a restrictor (310) inserted into the bore hole (10) at a desired depth which minimizes stirring action (40) and impedes the upward flow of the fluids and a sensor (320) measuring any difference in fluid pressure above and below the restrictor. The restrictor (310) is pulled upwardly by cable (340) connected to powered reel (430 and 440) at a velocity sufficient to maintain the differential pressure (.DELTA.P) across the restrictor (310) at zero. When the differential pressure (.DELTA.P) is zero, the velocity at which the restrictor (310) moves upwardly in the bore hole (10) is equal to the velocity of the fluids in the vicinity of the restrictor (310). The velocity of the pulled cable (340) can be sensed and recorded as the velocity of the multi-phase fluids.
摘要翻译：本发明提供一种测量井眼中高低流体速度的系统和方法，特别是对于表现出搅拌作用的流体。所述系统和方法（300）包括以期望的深度插入钻孔（10）中的限制器（310），其使搅拌作用（40）最小化并阻止流体的向上流动;以及传感器（320），其测量任何差异限流器上下流体压力。通过连接到动力卷轴（430和440）的电缆（340）向上拉动限流器（310），该速度足以将跨越限流器（310）的差压（DELTA P）维持在零。当差压（DELTA P）为零时，限流器（310）在钻孔（10）中向上移动的速度等于限流器（310）附近的流体速度。拉动的电缆（340）的速度可以被感测并记录为多相流体的速度。

摘要： Treatment composition is released into a well by lowering a container filled with the composition to the bottom of the well. The corrosive well fluid dissolves the composition through the open upper end of the container and corrodes away the walls of the container from the inside out. The outer surface of the container walls is coated with a material, such as tetrafluoroethylene, which acts as a barrier to the well fluid to prevent it from directly contacting the outer wall surface. In this manner treatment composition is gradually released from the top end of the ever-diminishing length of container and the container is degraded in the well.

摘要： The invention provides a system and method for measuring fluid velocity in well bores. The system and method includes the provision of a plurality of spaced magnetic markers (70) located at predetermined distances (d) along a line (40), a weight (100) connected to one end of the line (40) for holding the line at the bottom of the bore hole, and a basket (110) engaging the line for carrying a self-contained and sealed electronics package (90). When the basket (110) is selectively opened after a predetermined period of time, it flows upwardly at the rate of the fluid carrying the electronics package (90). A sensor (400) in the electronics package (90) detects the position of each magnetic marker (70) on the line (40) and the time elapsed between the detection of each successive markers (70) stored in memory. When the electronics package (90) is removed from the bore hole, the elapsed times stored for each marker (70) are read out and the velocity of the fluids flowing between each magnetic marker (70) is determined.

摘要： The invention provides a system for the detection of leaks in the primary barrier (150), the secondary barrier (130), and the inner hull (110) of the primary and secondary insulation spaces (140 and 120) of a cryogenic cargo tank (10) carrying liquified natural gas in a transport ship (20) wherein an inert gas is maintained at a first predetermined pressure (P.sub.NP) in the primary insulation space (140) which is less than the pressure of the cargo gas (P.sub.CH.sbsb.2) and wherein the inert gas is maintained at a second predetermined pressure (P.sub.NS) in the secondary insulation space (120) so that the second predetermined pressure (P.sub.S) is less than the first predetermined pressure (P.sub.NP) and is also less than atmospheric pressure (P.sub.O). A gas sensor (930) is placed in the primary insulation space (140) to detect any leaks in the primary barrier (150) and a sensor (940) is placed in the secondary insulation space (120) to detect the presence of any oxygen due to a leak in the hull (110). The flow of the inert gas into and out from both the primary and secondary spaces (140 and 120) over a period of time is measured and any differences in the flow rates in and the flow rates out of each of the insulation spaces is detected. Any differences in the flow rates is indicative of a leak occurring in the secondary barrier and is further indicative of the size of the leak.

摘要： A coking drum system is provided in combination with a process control unit wherein the rate of material delivered to a coking drum during a coking process timing cycle is monitored and the quantity of material received by the coking drum is continuously derived therefrom. Based on this derived quantity of delivered material, the quantity of feed material required to fill the drum to a preestablished level with coke, at the completion of the timing cycle, can be predicted. The flow rate of feed material to the coking drum is accordingly adjusted so that the amount of coke produced in the drum during one timing cycle is optimized.

摘要： A method and apparatus for measuring the amount of fluids in a two-fluid mixture flowing in a conduit wherein the fluids have different electrical conductivities. The apparatus includes a predetermined grid pattern of a first plurarlity of horizontal and a second plurality of vertical wires all under tension wherein the vertical wires are spaced a predetermined distance from the horizontal wires. When the lower conductivity fluid, such as water, occupies the predetermined space at the intersection of a vertical and horizontal wire, an electrical signal is generated. The electrical signals generated from each predetermined spacing having the lower conductivity fluid there between are counted and the percentage concentration of the lower conductivity fluid in the higher conductivity fluid is determined for each time interval.

摘要： A method and apparatus are provided for detecting and locating holidays in an insulating coating of a subterranean pipeline. An alternating current is induced in the portion of the pipeline being surveyed. The pipeline is tracked by sensing the normal electromagnetic field generated by the current flowing in the pipeline. Leakage current indicative of the location and magnitude of a holiday in the pipeline coating is sensed by a pair of coil members adapted to be located above the ground on opposite sides of a vertical plane including the longitudinal axis of the pipeline with the central axes of the coil members being oriented generally parallel to the central axis of the pipeline, whereby an electrical current signal is induced in the pair of coil members by an electromagnetic field generated by the leakage current. The electrical current signal is displayed to provide an indication of the location and magnitude of the holiday.
