Study and application of tools of stratified waterflooding for 101.6mm casing well

Well body track logging technology for cased wells;

Application and analysis of natural gamma-ray spectral logs in cased well;

Acoustic variable density logging in cased wells records the received full acoustic waveform varying with time which can be used to check the cementing quality and fracturing effect and to extract longitudinal wave data which can reflect formation porosity and transverse wave data which can reflect formation rock strength.

Application of ultrasonic imaging well logging technology in the casing well;

The numerical calculation and influencing factors of casing well resistivity logging are studied.

Engineering inspection technique (EIT) in casing well is widely adopted in oil field developments.

By using ANSYS software,this paper makes the mechanical analysis on the structure of oil well casing,builds the mechanical model in accordance with the actual projects and conducts nonlinear contact analysis solution for it,which is more practical than simply for the casing and whose conclusion is more reasonable.

The deformation of oil well casing by creep of surrounding rocks is analysed with finite element methods.

Combined with practical engineering of oil fields,the influences of one opening and multi-openings with different shapes on a oil well casing are studied in this paper.
