摘要： A three-dimensional simulating device for the stratum stability in natural gas hydrate exploitation includes a three-dimensional model located in an environmental control unit, an axial pressure control unit, and a post-processing unit. An inner cavity of the three-dimensional model is divided into a sealed simulating cavity and a sealed axial pressure sealing cavity by an axial pressure sealing piston arranged in the inner cavity. A vertical well and a horizontal well stretch into the simulating cavity. The axial pressure control unit, the environmental control unit, and a plurality of sensors in the three-dimensional model are electrically connected to the post-processing unit. This simulating device simulates the external environment and combines in-situ synthesis and decomposition of a hydrate with stratum stability, thereby achieving high reliability and high accuracy, comprehensively evaluating mechanical characteristic change of the stratum and the stratum stability to provide guidance in natural gas hydrate exploitation.

摘要： An oil production well is drilled into a kerogenous chalk source rock comprising (i) type IIs kerogen and (ii) shallow naturally-occurring unconventional oil derived from the type IIs kerogen that is resident within pore space of the source rock. In some embodiments, the production well is drilled at a location where the geothermal gradient is at least 3 degrees C. per 100 m is present at or near the production well. It is believed that the presence of this geothermal gradient accelerated maturation of the type IIs kerogen of the source rock to convert a portion of the type IIs kerogen into the unconventional oil. In some embodiments, the shallow production well is non-vertical. In some embodiments, at depths that are shallow and within the source rock, the production well is cased and perforated. Oil from the source rock may be produced via the production well and the shallow-depth perforated locations thereof.

摘要： A method of optimizing production of wells using choke control includes generating, for each well, an intermediate solution to optimize the production of each well. The generating includes using an offline model that includes a mixed-integer nonlinear program solver and includes using production curves based on a choke state and a given wellhead pressure. The method further includes calculating, using a network model and the intermediate solution of each well, a current online wellhead pressure for each well. The method further includes setting the intermediate solution as a final solution based on determining that a difference between the current online wellhead pressure of each well and a prior online wellhead pressure of each well is less than a tolerance amount. The method further includes adjusting, using the final solution of each well, at least one operating parameter of the wells.

摘要： In some aspects, techniques and systems for operating a subterranean region model are described. A band matrix that represents well system fluid flow in a subterranean region is accessed. The band matrix includes flow variable coefficients based on governing flow equations for the well system fluid flow. A first elimination is performed on an upper part of the band matrix. The upper part of the band matrix includes a first subset of the flow variable coefficients corresponding to a first subset of flow variables. In parallel with the first elimination, a second elimination is performed on a lower part of the band matrix. The lower part of the band matrix includes a second subset of flow variable coefficients corresponding to a second subset of the flow variables. An intermediate part of the band matrix can be solved. The intermediate part of the band matrix includes other flow variable coefficients.

摘要： In order to predict properties of a formation in a near-wellbore area exposed to a drilling mud rheological properties of the drilling mud, of a filtrate of the drilling mud and of a reservoir fluid are determined. Properties of an external mudcake, porosity and permeability of the core sample are determined. A mathematical model of the external mudcake is created. The drilling mud is injected through a core sample and dynamics of pressure drop across the sample and dynamics of a flow rate of a liquid leaving the sample are determined. Using an X-ray micro Computed Tomography a profile of concentration of particles of the drilling mud penetrated into the sample is determined. A mathematical model is developed for the internal mudcake to describe dynamics of changes in concentration of the particles of the drilling mud in a pore space of the core sample. A coupled mathematical model of the internal and the external mudcakes is created and parameters of the mathematical model of the internal mudcake are determined providing matching of simulation results to the experimental data on injection the drilling mud through the core sample and to the concentration profile of the particles of the drilling mud.
