X oilfield is a typical strong bottom water reservoir in Bohai Sea. It is
developed by single sand body horizontal well. The edge and bottom water of the
reservoir is active and natural energy development mode is adopted. At present,
the comprehensive water cut of the oilfield is more than 96%, and has entered
the stage of high water cut oil recovery. At present, fluid extraction from old
wells and new adjustment wells are the main ways to increase oil production.
With the deepening of development, the distribution of underground remaining
oil is becoming more and more complex. In order to further improve the
implementation effect of adjustment wells, the study of residual oil
distribution law is increasingly important, and the study of water ridge
morphology of horizontal wells in bottom water reservoir has an important
guiding role in the study of remaining oil distribution. The main contents of
this paper are as follows: the influence of horizontal well spacing, vertical
and horizontal permeability ratio, single well liquid production, vertical
position of horizontal well, oil-water viscosity ratio, water cut and interlayer
on water ridge morphology. These understandings can effectively guide the
deployment and optimization of adjustment wells. It provides technical support
for the prediction of watered out thickness and optimization of adjustment well
layout scheme in X oilfield, and guides the further development and production
of the oilfield.
