摘要： A cased hole pressure test tool is used to determine the integrity of cement between two points in a borehole in terms of permeability or transmissibility. The test tool drills at least one probe hole through the casing up to the cement. In one embodiment, two probes are set and the dissipation of a pressure pulse through the cement initiated by the first probe is observed by the second probe. In another embodiment, one probe hole is in hydraulic communication with the borehole fluid and a single offset probe is set in another probe hole. Fluid (water) is then added to the borehole to cause a pressure increase in the borehole fluid. Detection of the pressure increase through the cement by the offset probe is indicative of a loss of hydraulic isolation. Packers may be used to isolate the portion of the borehole under test. A mechanism for generating a pressure pulse of known magnitude is also described.
摘要翻译：套管孔压力测试工具用于确定钻孔中两点之间的渗透性或透射性的水泥的完整性。测试工具将至少一个探针孔穿过套管钻到水泥上。在一个实施例中，设置两个探针，并且通过第二探针观察到通过由第一探针引发的水泥的压力脉冲的耗散。在另一个实施例中，一个探针孔与钻孔流体液压连通，并且单个偏移探针设置在另一个探针孔中。然后将流体（水）加入到钻孔中以引起井眼流体中的压力增加。通过偏移探测器检测通过水泥的压力增加表明液压隔离的损失。封隔器可用于隔离被测钻孔的部分。还描述了用于产生已知大小的压力脉冲的机构。

摘要： A method and apparatus is disclosed for testing a blowout preventer (BOP) by: using a drillpipe to install a test plug into one end of the throughbore of a (BOP); using a valve in the BOP to isolate the opposite end of the throughbore of the BOP, using piping to connect the output of a cementing unit to the throughbore of the BOP; using the cementing unit to increase the pressure in the throughbore of the BOP to a predetermined level; displaying the pressure in the piping as a function of time; and displaying the pressure in the piping as a function of time for the same blowout preventer system at an earlier time when leakage was deemed to be within predetermined acceptable limits. The pressure decline caused by a leak can be detected reliably and efficiently with high-resolution pressure data.

摘要： An externally testable redundant connection for a subsea well includes a tube, a connector assembly, and collar. The connector assembly includes a jam nut over the tube; a ferrule over the tube adjacent the jam nut; and a double jam nut disposed over the tube adjacent to the ferrule. The double jam nut includes a test port adapted to receive a test fluid through the test port for determining if the primary seal and the secondary seal are providing a leak proof sealing engagement. The collar engage the tube and transfers an axial force from the double jam nut and compresses the tube into a female profile forming a primary seal. A secondary seal is formed from a compression of the ferrule into the double jam nut using the jam nut.

摘要： The present invention includes a method and system for detecting and locating a breach of a pipe in nested multi-pipe petroleum wells through the use and measurement of pressure valves and pressure sensors. The system “locates” breaches in the sense that it determines in which pipe or pipes, if any, in a nested multi-pipe production well the breach exists. The method comprises the steps of, first, connecting at least two of the well pipes of a nested multi-pipe production well to a collection reservoir to allow fluid communication from the well into the reservoir; second, sealing the well pipes to maintain the pressure therein; third, measuring a pressure parameter within each of said at least two well pipes until said pressure parameter indicates a stabilization of pressure therein; fourth, altering the pressure within one of the well pipes; fifth, measuring a pressure parameter within the other well pipes; and sixth, stabilizing the pressure in the well pipe within which the pressure was previously altered. According to one aspect of the invention, a system controller executes a predefined program, which detects breaches between pipes comprising the production well by selectively altering pressure into the pipes and measuring the pressure change within the remaining well pipes. A change in the pressure indicates that the well pressure has escaped the well pipe through a breach therein. In this manner, the presence and location of breaches can be detected, and appropriate repair steps undertaken, before substantial contamination of the environment occurs.

摘要： A packer cup for use in sealing the interior of a pipe under pressure is described. The cup uses a bell-shaped end which has a lip of softer material which is integral with the body of the cup which is harder material. Under pressure the lip expands against the side of the pipe and as pressure increases the body of the bell also expands against the pipe.

摘要： Devices and methods for fluid flow control within a production tubing string wherein a temporary flow blockage is established and selectively removed from the tubing string so that pressure testing or operation of a hydraulic tool within the string may be performed. A flow control device includes a housing that defines a flowbore therethrough with a restricted diameter portion. The restricted diameter portion presents a seating surface for a plug member and is provided by an annular shell that is shaped to project convexly inwardly. The shell may be fashioned of metal, elastomer or another suitable material, and it is capable of yielding to permit passage of a plug member upon application of a suitably great amount of fluid pressure. In operation, a plugging member is dropped in to the tubing string from the surface of the well and seats upon the seating surface. The tubing string is then pressured up to a first fluid pressure level for testing, tool operation, or the like, and the pressuring up will urge the plugging member against the plug seat in order to effect a fluid seal. When it is desired to remove the plugging member from the tubing string, and reestablish fluid flow through the tubing string, fluid pressure above the plugging member is raised to a second, overpressure level. The plug is then urged through the restricted diameter portion and expelled from the device to the wellbore sump below.
摘要翻译：在生产油管柱内进行流体流动控制的装置和方法，其中建立临时流动阻塞并且从油管柱中选择性地移除，以便可执行液压工具在油管内的压力测试或操作。流量控制装置包括壳体，该壳体限定了通过其限制直径部分的流道。限制直径部分呈现用于插塞构件的就座表面，并且由形状为凸出地向内突出的环形壳体提供。外壳可以由金属，弹性体或其他合适的材料制成，并且在施加适当大量的流体压力时，其能够屈服以允许塞子构件通过。在操作中，堵塞构件从井的表面落入油管柱中并且座在座面上。然后将管柱加压到第一流体压力水平以进行测试，工具操作等，并且加压将推动堵塞构件抵靠插塞座以实现流体密封。当需要从油管柱中移除堵塞构件并且重新建立通过油管柱的流体流动时，堵塞构件上方的流体压力升高到第二超压水平。然后将塞子通过受限制的直径部分推压并从装置排出到下面的井筒底池。

摘要： A method and a device for testing of a well, such as in a well liner, a newly drilled hole, and the like, is disclosed. The method is characterised in that a plug is directed down into the well, that the plug is fixed towards the wall of the well the sealing means of the plug is activated to seal against the wall of the well, and after the testing has ceased the sealing function is removed by disintegrating the plug. Preferably a plug of a disintegratable material is used, such as a ceramic material, glass or the like.

摘要： Apparatus and methods for gravel packing, isolating and testing a sand screen completion of a wellbore in a single trip are disclosed. One method comprises inserting into the wellbore a sand screen assembly, an isolation pipe, and a test assembly on a workstring. A gravel pack operation is performed, and the isolation pipe is shifted to a position in sealing contact with the sand screen assembly, thereby isolating the sand screen assembly. The test assembly is then shifted to a configuration that provides hydraulic communication between the interior of the isolation pipe and the workstring-wellbore annulus above the test assembly. Imposing pressure on the workstring-wellbore annulus then hydraulically tests the integrity of the seal between the isolation pipe and the sand screen assembly.

摘要： A subsea well has a tubing hanger which has an annulus bore and a production bore. A check valve is located in the annulus bore. A running tool runs the tubing hanger on a monobore riser such as a drill string while holding the check valve in the open position. After setting and testing, the running tool is lifted and a blowout preventer is closed around the landing string. The operator monitors the choke and kill line of the drilling riser, which will be in communication with the check valve. If the check valve is leaking, an annulus plug may be installed in the annulus bore. The installation of the annulus plug may be handled by using a retrieval tool configured to align the annulus bore with the landing string passage. A wireline tool may be lowered through the landing string and retrieval tool to retrieve the check valve and install the plug. Alternately, the check valve may remain in the tubing hanger and the plug is set in the annulus bore above it. The check valve is retained in the open position, if so.
