Publication number: 20200040682Abstract: The present invention discloses a method for lowering an oil pipe in a gas well without well-killing, a soluble bridge plug and a material preparation method thereof, wherein, the method comprises the steps of: lowering a bridge plug in a wellbore such that the bridge plug blocks the wellbore at a predetermined location in the wellbore; injecting water in the wellbore after the pressure in the wellbore has been relieved so as to replace gases in the wellbore; and lowering an oil pipe in the wellbore to the location of the bridge plug. The method for lowering an oil pipe in a gas well without well-killing, the soluble bridge plug and the material preparation method thereof provided in the present invention successfully solve the problem of high cost for lowering an oil pipe under pressure after a fracturing fluid has been injected into the casing.Type: ApplicationFiled: April 4, 2018Publication date: February 6, 2020Inventors: Xianwen Li, Qiaorong Han, Yanming Zhang, Xu Ma, Zhanguo Ma, Yangming Hu, Changjing Zhou, Yuanxiang Xiao, Huaqiang Shi, Baochun Chen, Yonghong Gu, Xiaoyong Wen, Xuan'ang Lai, Yong Ding, Liang Ye, Qianyun Zhao, Xinxing Ma, Yajuan Wang, Man Bi, Hua Shi, Mingfang He, Xiaorui Liu, Wei Gao, Hongying Li, Yun Ling, Ruifen Hao, Lei Shen, Guohui Su, Shaowei Zhou, Shusheng Li, Zhe Li

Publication number: 20200040685Abstract: Methods and apparatuses are provided for clearing a wellbore using a component for milling and a component for suctioning within a wellbore. Obstructions such as ball frac seats, bridge plugs, or formation material can be milled within a wellbore. As a result, larger, unrestricted, diameters can be obtained within the liner/wellbore. The cleared wellbore can allow for various remedial tools to be run into the liner/wellbore. In addition, the milled particles can be suctioned/vacuumed up and can be pumped/pushed to surface in an underbalanced fashion. In some embodiments, this can be achieved by incorporating a bottom-hole pump or a venturi component into the bottomhole assembly. The system can be deployed using a spoolable single or multi-conduit coiled tubing system and can be configured as a well intervention or work-over technology. In some embodiments, the clearing equipment can be temporary or mobile.Type: ApplicationFiled: October 15, 2019Publication date: February 6, 2020Applicant: QUANTUM DOWNHOLE SYSTEMS INC.Inventor: Steven WINKLER

Publication number: 20200040686Abstract: A stripper packer coupling assembly can include a packer operable to receive a tubular therethrough and form a seal about the tubular. The packer can comprise a plurality of coupling protrusions, each having a coupling head defining a first capture interface. Additionally, the stripper packer coupling assembly can include a capture mechanism. The capture mechanism can comprise a guide member having a plurality of guide openings, each operable to receive one of the plurality of coupling heads therein. The capture mechanism can also comprise a plurality of capture members, each defining a second capture interface. capture members can be operably coupled to one another such that they are simultaneously movable relative to the guide member and the coupling protrusions between a capture position and a release position. In the release position, the capture members can facilitate passage of the coupling heads through the guide openings.Type: ApplicationFiled: August 3, 2018Publication date: February 6, 2020Inventors: Faisal Yousef, Tommy Vu
