摘要(Abstract):
在以往重复地层测试器、注水井分层测压2种监测小层压力方法的基础上,引入了利用测井曲线确定异常压力层的方法,分析了利用测井曲线计算地层压力与实测RFT压力的差异,剖析了注水井钻关后的油层泄压规律,总结了3种异常压力层测试方法在开发调整中的应用效果及适应范围:一是在正常开发调整中利用小层压力对蹩压层泄压,防治套损;二是在钻关管理中利用小层压力资料调控地层压力剖面,并制定钻关恢复方案;三是利用测井曲线在钻关后对萨一组进行高压层普查。
Based on original two sub zone monitoring methods of repeating formation tester and injector stratified manometry, logging curve is introduced to determine abnormal pressure zone. Logging curve is used to calculate the difference between formation pressure and measured RFT pressure. Oil layer drainage rule after injector drilled is analyzed, and three test methods of abnormal pressure zone about development effect and applicable range during the development modification are concluded:first , sub zone pressure is used for decompression of building the pressure zone and c casing damage control during the normal development adjustment; second , sub zone pressure data is adopted in the management of well drilling to regulate formation pressure profile and to formulate recovery program of well drilling; at last,logging curve is used for general investigation of abnormal pressure zone of SaⅠformation after well drilling.
