  • Patent number: 9869649
    Abstract: Examples of nano-level evaluation of kerogen-rich reservoir rock are described. A micro-scale beam is formed from kerogen-rich reservoir rock. The beam has reservoir rock and kerogen, which has polymeric properties. A maximum dimension of the micro-scale beam is at most 1000 micrometers. A mechanical experiment that includes a tension test or a compression test is performed on the micro-scale beam. The mechanical experiment is imaged using a scanning electron microscope (SEM). A material parameter of the kerogen in the micro-scale beam is determined based on results of the mechanical experiment and images obtained responsive to the imaging. The material parameter includes a behavior of the kerogen in response to the mechanical experiment. The behavior of the kerogen can be used to determine, among other things, the energy required to break kerogen in a kerogen-rich shale to improve hydraulic fracturing efficiency.

The test material is disposed between the first and second surfaces. The assembly also includes a thickness detector that automatically detects a thickness of the test material. Moreover, the assembly includes an actuator that moves at least one of the first and second surfaces toward the other of the first and second surfaces to compress the test material to a predetermined percentage of the detected thickness of the test material. Additionally, the assembly includes a load detector that detects a compression load of the test material and that detects a change in the compression load over time.

  • Patent number: 8789456
    Abstract: A cylinder portion is divided into a cylinder main body, and two side cylinders coupled to opposite ends of the cylinder main body. The cylinder main body is configured so that a sample-enclosing capsule in which a sample and a pressure medium are enclosed can be disposed inside the cylinder main body. Pistons for load transmission are disposed at opposite ends of the interior of the cylinder portion; and locking nuts are provided on the outer sides of the positions. The pistons are moved in an axial direction by screwing the locking nuts. With this configuration, a piston cylinder-type high-pressure generating device in which a cylinder having a small outer diameter is formed of a non-magnetic material can generate a high pressure while securing a sample space having a predetermined effective volume.

  • Publication number: 20140130604
    Abstract: A key testing device is for testing a key with a keycap. The key testing device includes a loading unit and a sleeve. The loading unit includes a block and a rod. The rod includes a first end and a second end. The first end is detachably connected the block. The sleeve is sleeved around the loading unit, and the sleeve includes a partition plate with a through hole. The second end can pass through the through hole. When the sleeve is above the key and the second end contacts the keycap, the gravity of the loading unit is turned from the partition plate to he applied on the keycap, Consequently, since the key testing device can make the pressure pressing on the key be accurate via a loading unit, the probability of misjudgment is decreased.
