1. 考虑到油气田高效、安全钻井的需要，依据不同的压力异常类型，建立了定量控制异常压力的计算模型，确定了注水井合理关井停注时间、最大放溢量和最佳放溢时机以及生产井合理井底流压、增产量和增产时机等参数，给出了计算公式，推导出了注水井最佳关井停注时间、注水井最佳放溢量和生产井合理的增产量的定量计算方法，并通过某油气田的一口待钻调整井(T1井)对3种方法进行了验证，实现了对调整井异常高压的定量控制。
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.
2. 随着油田开发的逐步深入，外围特低渗透油田已进入加密调整阶段，由于特低渗透油田的地质特点，在设计钻井液密度过程中，按照大庆长垣内部调整井钻关措施进行钻井液密度设计，有许多时候注水井停注放溢后的井口压力一方面达不到钻关要求，另一方面也代表不了实际地层压力的增值，据此设计的钻井液密度很难满足安全钻井和保护油气层的需要。
During the process of the drilling liquid density design, we found that if we take the design according to the Daqing changyuan`s inter part measure of the adjust well shut drilling. On one side, the well mouth pressure cannot reach the request of drilling-shut, On the other side, it cannot represent the actual increasing of the geologic strata pressure.

3. 第二，在相关的钻关制度上，设计井距在300m范围内的注水井必须采取放溢降压措施，设计井距在300-600m范围内的注水井从钻井安全考虑采取停注措施即可。
Second, related drill-shut institution, the design well-well distance of water flooding well to be apart from in 300m must take the measure of open overflow to the pressure, the well-well distance between 300m to 600m should take the measure of stop flooding thinking from the drilling safety.
