在L型并电加热管网中，考虑到离散化控制存在滞后一拍的问题时，本文分析并获得了离散PI控制系统稳定范围时闭环根临界频率fnmax和采样频率fs之间的定量关系；针对存在滞后一拍可能引起系统稳态特性下降的问题，分析了PI控制滞后一拍对频域特性造成的影响，综合考虑并网指标、稳定性要求和离散化对稳态特性影响三个主要因素，推导了存在滞后一拍的离散化PI控制对最低采样频率的量化要求。

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.
