Abstract For improving the hole-enlarging capability, roundness and rock-breaking efficiency of nozzle in radial jet drilling, a new structure self-rotating was put forward. The flow features were investigated with sliding mesh model labortary tests also compared straight swirling integrated multi-orifice which have been applied drilling. results show that is energy concentrated, has longer effective distance, better capability impacts larger circular area at bottom drilling hole, other two...
In the petroleum industry, one of most serious problems encountered during cementing is failure at bonding interface. Many measures including casing-sand adhesion have been developed to improve bond strength. However, due lack detailed study technique, many questions remain. The primary goal this investigate influence on strength, and optimize parameters. An orthogonal experiment a supplementary were conducted. results indicated that can priority orders key factors are: sand grain size,...
Unexpected wellbore collision will bring potential or even catastrophic consequence to human beings and environment, the well-bore anti-collision technology is an effective approach reduce this kind of accident, function which specially important during process infill development drilling multi-well drilling. Through analysis existing technology, conclusion can be gotten that failure well bore brought by 4 factors include big error survey steering tool data,low accuracy, distortion loss...
An elastic-viscoplastic based finite element model has been developed to study the necking behavior of tube expansion for rate independent materials, dependent monolithic and laminated materials during dynamic loading. A numerical shows that loading will not delay diffused but localized necking; high strain sensitivity can significantly onset both sheets affect multiple-neck formation in high-speed The also a higher volume fraction clad layer with positive material sheet improves ductility.
ABSTRACT Rotary steerable drilling is an effective technique for directional wells. Given the currently inadequate understanding about variation of build-up rate rotary bottom hole assembly under different condition, a prediction model needs to be established. Aimed at push-the-bit assembly, continuous beam was applied study mechanical properties. Further considering drill bit cutting anisotropy, method built. Effects configuration parameters on were analyzed. Results showed that...
This study describes a method of determining the position adjacent well by analyzing geomagnetic anomalies in drilling. In experiment, put casing field respectively to simulate 3 conditions, which are vertical well, deviated and horizontal well. Study interference regional caused casing, summary law casing. Experimental results show that: magnetic intensity distortion is similar that but different from The scope amplitude N E component will increase with inclination, meanwhile V decrease...
