摘要： An in situ underground sample analyzing apparatus for use in a multilevel borehole monitoring system is disclosed. A casing assembly comprising a plurality of elongate tubular casings (24) separated by measurement port couplers (26) is coaxially alignable in a borehole (20). The measurement port couplers (26) include an inlet measurement port (70b ) for collecting fluid from an underground measurement zone (32) and an outlet measurement port (70a) for releasing fluid into the measurement zone (32). An in situ sample analyzing probe (124) is orientable in the casing assembly. The in situ sample analyzing probe (124) includes inlet and outlet probe ports (148b and 148a) alignable and mateable with the inlet and outlet measurement ports (70b and 70a). The inlet and outlet measurement ports (70b and 70a) typically include valves. When the operation of the in situ sample analyzing probe (124) causes the valves to open, the interior of the in situ sample analyzing probe (124) is then in fluid communication with the exterior of the measurement port coupler (26). A circulating system located in the in situ sample analyzing probe circulates fluid collected through the inlet probe port (148b) of the in situ sample analyzing probe (124) and the inlet measurement port (70b). The collected fluid is analyzed by chemical analyzing apparatus in communication with the circulating system. After in situ analysis, the circulating system releases at least a portion of the fluid through the outlet probe port (148a) and the outlet measurement port (70a) into the measurement zone (32). Alternatively, collected fluid can be stored for transportation to the surface for offsite analysis.

摘要： A nipple is provided downhole as part of a tubing (drill string or production) string. The nipple has an interior passage with recesses therein and a seat. A data probe attached to a wireline traverses inside of the tubing from the surface to the nipple. The data probe forms a valve that seats in the nipple so as to shut in the well and allow formation fluid pressure to build. A first latch deploys into a recess in the nipple to retain the probe in place against the formation pressure. A bypass is provided so as to equalize pressure across the data probe, when the probe is to be released. The bypass is kept closed by a second latch that deploys into another nipple recess. When the probe is to be retrieved to the surface, the bypass is opened by unlatching the second latch, thereby allowing pressure to equalize. The probe is unseated by unlatching the first latch. The probe has instrumentation and a sampling chamber which can be brought to the surface during flow periods of a test. In addition, a sampling tool is provided. The sampling tool is dropped on a wireline so as to impact an actuation surface inside of the tubing. Upon impact, a valve is momentarily opened, and fluid enters a sample chamber. After the impact, the valve closes and the sampling tool is retrieved to the surface.

摘要翻译： 作为管道（钻柱或生产）串的一部分，井下提供了一个乳头。 乳头具有其中具有凹部的内部通道和座。 连接到电缆的数据探头从表面穿过管道内部到乳头。 数据探头形成一个位于乳头中的阀门，以便关闭井口并允许地层流体压力建立。 第一闩锁部署到乳头中的凹部中，以将探针保持在抵抗地层压力的位置。 提供旁路，以便当要释放探头时，均衡跨数据探头的压力。 旁路通过第二个闩锁保持关闭，第二个闩锁部署到另一个乳头凹部中。 当探针被取回到表面时，通过解锁第二个闩锁来打开旁路，从而允许压力平衡。 探针通过解锁第一个闩锁而松开。 探头具有仪器和采样室，可在测试的流动期间将其带到表面。 此外，还提供了采样工具。 采样工具落在电缆上以便撞击管道内部的致动表面。 冲击时，阀瞬间打开，流体进入样品室。 冲击后，阀门关闭，取样工具回收到表面。
