Intelligent separate injection technology in Qinghai oilfield lets well drink water

Page view

  The successful completion of layered injection of well 372 in China Petroleum Network marks the breakthrough of multi-layer injection technology in Qinghai oilfield and realizes intelligent separate injection. Up to now, the wellhead water injection pressure of this well is stable at 7 MPa, and the water injection amount of 3 injection layers meet the requirements of injection distribution.

  Part of the old Qinghai oilfield oilfield has entered the middle and late stages of development, low formation pressure and insufficient fluid supply, wells, wells, wells with high water, shut down wells increasing year by year. How to solve the problem of stable production in old oilfields has become the key to the construction of 10 million tons of Plateau oil and gas fields.

  Since the beginning of this year, Qinghai oilfield for multi-layer injection well technology backward, accounting for a long time, the well stratified waterflooding effect can not be guaranteed, to carry out real-time monitoring of cable pre injection technology research bottleneck of research and testing, research and development of intelligent water regulator and cable packer integration tools, special downhole communication apparatus ground control equipment and auxiliary tools, injection technology innovation has formed the real-time intelligent downhole preset Cable + ground wireless communications division.

  This process is based on intelligent water distribution device, multi information test and flow control combining unified whole in long-term underground, equivalent to the underground embedded "eyes" and "hands", can be real-time monitoring of underground layered reservoir parameters, dynamic changes, provide first-hand information for the optimization and adjustment of dynamic reservoir, promote the water flooding to enhance oil field development level, to ensure the reservoir water, enough water injection.

  In recent years, Qinghai oilfield in the old oilfield water injection, water injection efficiency as the goal, relying on the Qaidam Basin major special project, strong research intelligent injection, high temperature deep well injection, high salinity water treatment three water injection process, injection forming process technology has the characteristics of Plateau oil series. In the aspect of management innovation, Qinghai oilfield formed three assessment management system, establish the mode of operation management, unified to oilfield development division the crude oil production unit is responsible for the implementation of the responsibility to implement the management, technology and operation aspects, improve work efficiency, the old oil wells qualification rate of year-on-year an increase of 1.9 percentage points, water quality compliance rate of 90.1%.
