摘要： A selectively operable downhole valve for use with core sampling apparatus, the valve comprising a throughbore through which a first body may pass, and an obstructing member which is capable of selectively obturating the throughbore, the obstructing member being arranged to open or close the throughbore by movement of the first body with respect to the valve. A core sample of the formation may then be obtained and retrieved from the bore under pressure since the valve seals the bore downhole. Retrieving the sample under pressure maintains the integrity of the core sample so that subsequent analysis of the sample will more closely reflect the true characteristics of the formation.

摘要： An apparatus for handling a geological sample, such as a core from a formation is described. The formation may be a formation of an oil and/or gas well. The apparatus includes a container for receiving the sample and is characterised in that the container comprises at least one wall with a surface which can change its configuration in response to pressure changes.
A method of handling a geological sample obtained from a formation is also described and includes providing a container for receiving the sample. The container has a surface which is capable of changing its configuration in response to pressure changes. The sample is introduced into the container, and the configuration of the surface is changed to contact the sample. The container is then withdrawn from the formation.摘要翻译： 描述了用于处理地质样品的装置，例如来自地层的岩芯。 地层可以是油和/或气井的形成。 该装置包括用于接收样品的容器，其特征在于，所述容器包括至少一个具有表面的壁，所述壁可响应于压力变化而改变其构型。 还描述了处理从地层获得的地质样品的方法，并且包括提供用于接收样品的容器。 容器具有能够响应于压力变化而改变其构型的表面。 将样品引入容器中，并更换表面的构型以接触样品。 然后将容器从地层中取出。

摘要： The present invention relates to an apparatus and method for recovering a sample (12) from a subterranean formation. The apparatus comprises a receptacle (10) for receiving a sample (12) and at least two seal means (41, 42) disposed on an inner surface of the receptacle (10). The seal means (41, 42) can be arranged to allow a portion of the core sample (12) therethrough during the sampling process and to retain fluids within the receptacle (10) during recovery of the sample (12). The seal means can be provided with one or more fluid pockets (94) configured to change shape as the volume of fluid therein alters in response to a pressure differential. A plurality of pairs of seal means (41, 42) can be spaced along the length of the inner surface of the receptacle (10).
