Abstract A transfer zone is a kind of structure that produced to conserve deformation fault on both sides. Increasing numbers zones are being identified in rift basins, which areas petroleum accumulation and potential exploration targets. This paper provides numerical simulation method for the genesis development based geomechanical modeling. On basis three-dimensional (3-D) seismic interpretation, using Tongcheng as an example, activity parameter intensity index were established...
ABSTRACT Background Hippocampal subfield pathology is established in bipolar disorder (BD); yet no studies have investigated these alterations adolescents at clinical high risk for BD (MDD‐Sub), which a critical gap given adolescence as neurodevelopmental window early intervention. Methods We analyzed baseline 3D T1‐weighted MRI data from 72 Clinical High Risk “MDD‐Sub”MDD‐Sub vs. MDD‐nSub, 74 pure with MDD (MDD‐nSub), and healthy (HC) aged 12–18 years the sBEAD cohort. subfields were...
Archaean metamorphic basement reservoirs, characterized by the development of natural fractures, constitute primary target for oil and gas exploration in Bozhong Depression, Bohai Bay Basin, Eastern China. Based on analyses geophysical image logs, cores, scanning electron microscopy (SEM), laboratory measurements, tectonic fractures are identified as dominant type fracture. Their is primarily controlled lithology, weathering intensity, faulting. Fractures preferentially develop rocks with...
The Bozhong 19–6 Condensate gas field is the first giant discovered in Bohai Bay Basin recent years. reservoir has diverse space and strong heterogeneity.In this paper, we systematically summarize tectonic fractures development patterns explore main factors controlling clarify influence of on quality through core microscopic thin section observations, physical property data, imaging logging data. results show that major types study area are shear fractures, followed by tensile fractures....
Effective natural fractures are those that contribute to reservoir storage and conductivity. In this study, the effectiveness of in deep ultradeep reservoirs (depths > 6 km) is evaluated by using geophysical image logs, cores, microstructures, mechanical tests, geologic evidence tectonic context (including current situ stress) sedimentary faces diagenesis. Intraformational open-mode most common fracture type tectonically active region, their affected coupling between past activity,...
Abstract A small, portable, and user-friendly human-machine interaction testing tool for drilling instruments is designed developed to accommodate the underground multi-parameter measurement environment meet ground requirements of instruments. To improve reliability data transmission, we customized CAN (Controller Area Network) application layer protocol by dividing identifier frames reasonably. The prototype can send multiple commands instruments, also monitoring flow displays users.
Abstract In response to the current demand for drilling cost reduction, efficiency improvement, and safety in process, it is necessary collect a large amount of real-time downhole measurement data achieve monitoring wellbore pressure, tool efficiency,and speed.Nowadays,traditional while measuring instruments have disadvantages such as small storage capacity, volume, easy loss power due failure.Therefore, designing dynamic recorder based on NAND (Non-And) capacity memory, using small,...
Under the condition of meeting resolution, SAR real-time image can satisfy demands processing band by pre-filter and down-sample. Due to being in a special position signal processor, ranger needs very high operating speed quick frequency response. The principles methods are analyzed this paper study is focused on realization range down-sampling using FPGA. This pay more attention which following digital orthogonal mixing. After analyzing polyphase arithmetic, new method implemented FPGA put...
Interleaved parallel buck converter in charging new energy lithium battery, often use the traditional PI control first to battery constant current (CC) and then voltage (CV). The has disadvantages of slow response, poor inductor equalization, large output ripple. Thus, by analyzing circuit model four-phase interleaved converter, an strategy MPC is proposed. Firstly, a prediction established, cost function constructed find optimum, entire controlled accordingly. Because good dynamic response...
