Abstract: Techniques for hiding security-sensitive features in untrusted environments. The techniques include inserting, in a development build image, one or more security-sensitive scripts encrypted with a unique encryption key for the development build image, and inserting, in a release build image, the security-sensitive scripts encrypted with a different unique encryption key for the release build image. The techniques further include saving the unique encryption key for the development build image in an artifact repository, and securely deleting the different unique encryption key for the release build image. In this way, user access to certain software code or scripts, device files, and/or other security-sensitive features can be restricted in a manner that is more user friendly to software development and/or information technology (or “DevOps”) engineers.

Abstract: The present invention relates to a multi-capillary force curve averaging method based on the overall virtual measurement of a plurality of samples. The method includes the following steps: 1, taking m types of rock samples, obtaining a capillary force-saturation curve, an apparent volume and a porosity of each sample; 2, inspecting the quality of the capillary force-saturation curve of each sample and preprocessing the end points of each curve; 3, calculating an averaged wet phase saturation corresponding to different capillary force values of the plurality of samples under the overall virtual measurement of a plurality of samples; and 4, denoting data points on a graph by using the wet phase saturation as the abscissa and capillary force as the ordinate, and finally connecting all data points smoothly to obtain the averaged capillary force curve.

Abstract: The present invention discloses a method and device for studying fluid equilibrium distribution in heterogeneous oil and gas reservoirs. Firstly, a reservoir is divided into multiple layers according to permeability of the reservoir; a pressure-depth curve of formation water in surrounding rock is established; the pressure-depth curve of a non-wetting phase is made by passing through a point in the reservoir and taking a product of density and acceleration of gravity of the non-wetting phase as a slope; the pressure-depth curve of displacement pressure of the reservoir is added on the basis of the pressure-depth curve of the formation water; and the pressure-depth curve of the non-wetting phase is repeatedly compared with the pressure-depth curve of the displacement pressure to obtain static equilibrium distribution of fluid in the reservoir.

Abstract: The invention discloses a method for improving a recovery ratio of a braided well pattern of a hugely thick or multi-layer oil and gas reservoir, which improves the recovery ratio of the hugely thick or multi-layer oil and gas reservoir by designing the braided well pattern. The braided well pattern is designed through the following method: dividing a cubic development unit of the oil and gas reservoir; measuring a physical property parameter of the cubic development unit; calculating a well pattern design parameter according to the physical property parameter, wherein the well pattern design parameter includes a number of wells and a well bore track; and drilling a large-displacement horizontal well according to the well pattern design parameter.

Abstract: The application discloses an integrated method and structure for in-situ hydrogen production from coal seams and coalbed methane exploitation, belonging to the technical field of energy exploitation. The method comprises: injecting gasification agent through an injection well, exploiting coalbed methane and gasification gas through a production well. The injection well is a stepped horizontal well, the injection well is provided with at least one, and the projections of the horizontal sections of any two injection wells in the vertical direction do not overlap. At least one horizontal section of the stepped horizontal well is arranged in any coal seam to be mined. The method of the present application avoids the large-area continuous gasification of a single coal seam and the repeated position gasification of overlapping multiple coal seams, reduces the change range and degree of formation stress, disperses the underground void volume, reduces the risk of formation or ground collapse.
