摘要：针对扶余油田部分油水井吐泥岩严重、地层塌、鱼顶丢失等难点问题，采取救援井施工方式，利用新钻井眼轨遂，通过油层射孔井段作为联通媒介，使新、老井眼轨透形成一个 U型连通器，最终建立起一个联通关系，从而实施向新井眼轨迹注水泥浆达到封死老井眼上返通道目的。该项技术解决套管错断下部鱼顶完全丢失无通道，浅层泥岩地层严重塌和漏失，套内和套外大量吐泥岩，作业时无法对下部并筒及油层进行有效封堵。在沟通新老井眼轨迹采用化学堵剂和增注提压措施，相对有效的降低了无效分流作用，提高新老井眼之间良好的沟通关系和联通性能，最终实现了有效封固作用。在现场应用中取得了较好的效果，有效的对堵了这部分疑难井，为扶余油安全隐惠治理提供了新的方法。

Sulige Research Center, Petro China Changqing Oilfield Company, Xi'an 710018, China) Abstract: In Fuyu oil field wells spit mudstone serious, sloughing, lost the problems on the top of the fish, take relief well construction method, using new drlling trajectory, through reservoir perforated interval as China Unicom media, from new and old wells trajectory formed a U shaped connecting device, eventually set up a China Unicom, so as to implement to new wells trajectory cement injection to sealed wells eyes retum channel to. The technology to solve casing fault at the lower part of the fish top completely lost without channel, shallow mudstone strata serious collapse and leakage, set in sleeve and a lot of spit mudstone and operation cannot on the lower part of wellbore and reservoir were blocked. In the communication of the trajectory of the new and old wells by chemical plugging agent and augmented injection provided measures of pressure, relative effective reduces the invalid diversion effect, improve good communication relationship between new and old wells eyes and Unicom perfomance, finally realizes the effective sealing effect, In the field application, it has achieved good results, effectively blocking the difficult wells, and provides a new method for the safety management of Fuyu oilfeld.
