WZ13-1-1井漏层位置分析

The Analyses of Well Leaking Interval of WZ 13-1-1 Offshore Oil Field

温州13－1－1井8－1／2″井眼钻至3767～3772．8m时发生井涌，在井控过程中又发生井漏，根据井上的情况记录，通过计算分析，认为该井的漏失属于喷漏同层现象，即温层在3767～3772．8m的含砾中粗砂岩层。这一结论及分析方法对邻井钻井有参考价值。

The kicks occured when the WZ13-1-1 well was drilled to a depth of 3767-3772m and the leakage occured during the well control. According to the record of well condition and through calculation and analyses, it is judged that the above phenomenon is belonged to leaking and kicking in the same interval, ie, 3767-3772. 8 m medium sandstone with conglomerate- The result and analytic method are of reference value for drilling in neighoorhood wells.
