【摘要】 为减少地层污染、缩短施工周期,长庆油田在气井试气中采取分层压裂、合层排液,再下地层测试器进行分层求产的方法,实现了下一趟管柱进行多层试气求产的目昀。M25井首次应用该工艺取得成功,在对上层抽汲求产的同时,对下层关井恢复,并可对作业全过程进行实时监控。更多还原

【Abstract】 In order to reduce formation pollution and shorten operation cycle, the method applied in Changqing oilfield of fracturing to separated layers and unloading to commingled layers and then using formation testing tools to acquire potential of separated layers can make true the objective of conducting gas testing for multiple layers with one testing string. The first time of applying this tech in M25 well is successful for swabbing and obtaining production to upper layer and acquiring build-up pressure data by closing well and monitoring all operation process on real time.更多还原
