Abstract

Abstract

Neutron porosity logging while drilling (LWD) plays an important role in formation evaluation under LWD environment, so it has a great significance to study the logging response characteristic. Monte Carlo method is employed to build formation modeling under LWD conditions, and the response characteristic is simulated. The results reveal that the changing trend of porosity response of neutron logging while drilling is similar to that of wireline under the same conditions, the sensitivity of porosity curve in LWD to porosity is higher than wireline, but the neutron porosity logging response of LWD is affected severely by the drilling collar. The depth of investigation is related to formation porosity, and the depth of investigation and vertical resolution under the conditions in this paper is 28 cm and 19 cm, respectively. In high angle and horizontal wells, the effect of measurement azimuth on neutron porosity curve is slight. When the relative dip α is low, the midpoint of transition area of neutron porosity curve is close to the boundary surface. If α is less than 60°, the effect of the adjacent formation on porosity curve can be ignored.
