According to the oceanic environment condition encountered only once in 30 years,strength and security of riser are calculated and analyzed for Bozhong 34 oilfield in Bohai Sea,and its result is significant to offshore.

The acidization acquired favorable effect when the new multi-hydrogen acid system applied in BZ34-3 oilfield and the well yield exceeded 50% to 160% of proration production.

BZ342/4 oilfield is a typical complex faulted block,and is characterised by deep-buried multiple oil-bearing layers with low permeability,resulting in development difficulties and well completion complications.
