In recent years, S plant has implemented scale encryption adjustment, and the number of drilling shutdown wells increased year by year, which a greater impact on output oil fields. Because influence reservoir physical properties connection, wellhead pressure water well before is quite different, so uniform cycle can not be determined. order to minimize reduction in field production increase discharge costs, relaxed stable from 3 MPa 7 head 600 m injection for drilling.Through comparison time, production, cementing quality safety, it proved that feasible relax drilling. The parameters are optimized, test carried out, development effect comprehensively evaluated, feasibility effectiveness relaxation explored, provides technical reference operation.
