摘要
杜39-1井压裂后下入水力泵排液求产管柱,坐封封隔器后环空试压不合格,认为套管有漏点。下入套管找漏管柱,最终确定漏点在套管头。通过对该井找漏的方法与过程分析,提出了对于该类试油井在施工中注意的事项,对今后的试油施工具有一定的现实指导意义。
Hydraulic pump unloading production string is lowered in Du 39-1wellafter fracturing,and it is thought that the casing leaks for annulus pressure test is unqualified after the packer is set. The string of finding leakage in casing is lowered to ultimately determine that the leak is at the casing head. Through the analysis and process of the method for leakage of the well,the matters for the tested well paid more attention in operation are proposed,which has some practical guiding significance for the operation of oil test in the future.
