查询词典 well drilling

According to different types of abnormal pressure,computation model for quantitative control on the abnormal pressure was set up to meet the needs of efficient and safe drilling in oil-gas fields.Some important parameters were calculated that include reasonable shut-in time,maximum flowing yield and the best flowing time of the injection wells,and reasonable bottom hole flowing pressure,extra oil production and stimulation moment of the production wells.The quantitative computational methods of them were derived.Three methods were applied to one undrilled adjustment well T1 in certain oil-gas field achieving quantitative control to the abnormal pressure in the adjustment well.
