Optimization of shut-in time before drilling for each strata system in the drilling pass area in Block G

After the A oilfield enters the ultra-high water cut period, the production level is high, the comprehensive water cut is high and the production level is high. In recent years, the number of new wells has increased considerably, affecting the increase in production year by year. Faced with these two contradictions, a new scientific and effective drilling gateway management model has been explored to reduce the impact of drilling gateways on production. This will have a very important guarantee for the realization of A oilfield's continued stable production. Based on the research and practice of the drill-off area in Block G, this paper determines the minimum injection stop time before drilling-off corresponding to each set of formations according to the bottom hole pressure change law of the injection-stop well.
