基　　金：国家科技重大专项"连续管装备与应用技术"(2011ZX05036-006);非常规油气湖北省协同创新中心创新基金项目"连续油管页岩气水平井多段压裂工具研制"(HBUOG-2014-8)

摘　　要：为了使连续管断裂落井后的打捞简单、快捷,在连续管落鱼打捞特性分析的基础上,研制了连续管烂鱼头专属捞筒和捞矛。捞筒参数与连续管外径配套,并一一对应,捞矛参数也与连续管直径配套,并可适应同一直径连续管不同壁厚的情况,捞筒和捞矛的抗拉极限都比连续管推荐抗拉极限高15%~20%。现场应用结果表明,研制的打捞工具特别适用于连续管作业的油井,打捞成功率高,有效提升了油田企业的打捞作业水平,提高了作业效率。To facilitate simple and rapid recovery of lost fishes related to broken coiled tubing,special fishing barrel and fishing spear for broken coiled tubing have been developed after analyzing features of coiled tubing fish. Technical parameters of fishing barrels correspond well with OD of coiled tubing,whereas parameters of fishing spear coincide well with diameters of coiled tubing. In addition,these facilities can be used for coiled tubing with identical diameter but different wall thicknesses. Both the fishing barrel and the fishing spear have maximum strengths 15% ~ 20% times higher than the recommended strength of the coiled tubing. Site application shows that the new fishing tools are especially suitable for wells with coiled tubing. With high efficiency in fishing operations,such tools can effectively promote fishing performances.
