Pulsed jet significantly affects the pore pressure of deep formation and then mechanical ROP. In this paper, effect pulsation on in is studied by finite element method. Under pulsed jet, maximum relative negative along wellbore axis, farther it to borehole smaller is. With increase pulse frequency, increases point moves upward. The optimum frequency from 50 Hz 500 Hz. There a linear relationship between amplitude pressure.
Rotary-steerable drilling provides unique features such as an extended reach and accurate well trajectory control. These characteristics can notably increase efficiency safety. One of the main technical difficulties rotary-steerable is dynamically measuring spatial attitude at bottom rotating drillstring rotates. We developed a strap-down measurement system, with triaxial accelerometer magnetometers installed near bit. The inclination azimuth be measured in real time even Although magnetic...
Different from oil properties, gas properties (gas formation factor, viscosity, and Z-factor, etc.) have nonlinear behaviors with pressure changes. However, many scholars use the average or pseudopressure concept to simplify phenomenon for easier solutions. Gas flow in shales is believed be a complex process multiple mechanisms including continuum flow, slip diffusion, ad-desorption, stress sensitivity of fractures (natural induced) permeability multiscaled systems nano- macroporosity....
Carbonate rocks have a complex pore structure, show strong heterogeneity, and wide range of velocities that lead to more complicated velocity-porosity relationships compared with sandstones. We designed prepared 72 carbonate synthetic cores known structures according the control variate principle. measured P- S-wave these by an ultrasonic pulse transmission method, analyzed effects aspect ratio (AR) size [Formula: see text] on velocities, experimental results predictions effective medium...
Existing methods of well-logging interpretation cannot be applied accurately for the exploration and evaluation carbonate reservoirs because fracture development. Based on density obtained by core analysis in a reservoir located Ordos Basin, northwest China, three types (low density, medium high density) target formation were identified. We investigated effect fractures acoustic logging signals time frequency domains Hilbert-Huang transform (HHT) extracted 11 features domain nine domain....
Summary This is the second paper of a series in which we study heavy oil porous media. The first dealt with an experimental (Wang et al. 2008), whereas mathematical and simulation presented here. research program stems from need to predict field performance class heavy-foamy-oil reservoirs. These reservoirs show better-than-expected primary performance: lower production gas/oil ratios (GORs), higher-than-expected rates, higher recovery. A mechanism used account for observed that liberated...
In the oil drilling process, measurement-while-drilling system is usually used to provide real-time monitoring of position and orientation bottom hole. Usually drill string attitude measured on condition that static. Particularly, in rotary steerable application, it a challenging problem accurately measure spatial (inclination, azimuth, tool face) with rotating. A set "strap-down" measurement was developed this paper, triaxial accelerometer fluxgate were installed near bit, well deviation...
