Record of domestic construction of drag fracture in Tuha Oilfield
Chinese oil network news reporter was informed in August 15th, the Turpan Hami oilfield in Lake 33-51 well implementation of coiled tubing perforation + bottom seal drag annulus sand fracturing is divided into 9 sections, a new record of 5 highest one-day drag fracturing construction period, creating a continuous oil pipe with a bottom seal drag domestic fracturing efficiency application record. At present, Lake Ping 33-51 is pumping operations.
The lake is flat 33-51 wells of Tuha oilfield company deployed in three Santanghu basin Niuquanhu area block a wells. In the process of construction, the three oil production plant and Santanghu Turpan Hami underground fracturing company team, coiled tubing unit are discussed in detail and analysis, according to the mainstream of fast drilling bridge plug staged fracturing horizontal cluster rebuilding of uneven defects, seek the process improvement, continuous improvement of fracturing scheme. Construction personnel are divided into 9 sections to carry out hydraulic sand blasting perforation + annular sand fracturing, so as to achieve the purpose of accurate positioning of reservoir desserts. There is no need to plug or drill plug in drag fracturing, the operation is more compact, and the pollution damage of reservoir is less. The well takes 4399 cubic meters of liquid and 401.5 cubic meters of sand entering the well. The pass rate of the data is 100%.
