ABSTRACT: The geological conditions of shallow offshore delta oil reservoirs are
complex. Under the condition of less well data and larger well spacing, the
traditional reservoir configuration method is difficult to solve the detailed
study of such reservoirs in offshore oil fields. Based on the comprehensive
analysis of the seismic phase, data of well log. The paper identifies criteria
of the quaternary configuration boundary in shallow water delta of different
types with distributary sand dam is
established. At the same time, this paper used sensitive factor to construct the
edge detection operator based on the amplitude attribute, characterizing the boundary of sand body thickness mutation
or physical property mutation quantitatively,
realizing the quantitative characterization of four-stage configuration boundary
in the region with no wells or few wells, guiding the efficient development of offshore
shallow water delta oilfield, and realizing the increase of storage and production
of Bohai oilfield.
