Drilling azimuth gamma embedded design

Embedded; LWD; azimuth gamma; numerical simulation; Monte Carlo method

Embedded drilling azimuth gamma design, the use of radioactive measuring principle embedded gamma measurement while drilling a short section analysis. Monte Carlo method, in response to the density of horizontal well logging numerical simulation of 16 orientation, the orientation of horizontal wells analyzed, caliper, bed boundary location, space, different formation density, formation thickness, and other factors inclined strata dip the impact by simulating 137Cs sources under different formation conditions of the gamma distribution, to determine the orientation of drilling density tool can detect window size and spacing, draw depth of the logging methods. The data 360 ° azimuth imaging, image processing method to obtain graph, display density of the formation, dip and stratigraphic thickness and other parameters, the logging methods obtain real-time geo-steering. To establish a theoretical basis for the orientation density logging while drilling method implementation and application of numerical simulation in-depth study of the MWD azimuth and density log response factors of horizontal wells.
