New multi-functional irrigation pump successfully developed
Recently, a set of wellbore irrigation, waste recycling, tubing pressure test and other multi-functional irrigation pump in Shengli Oilfield successful mining operations team successfully developed by the scene trial and oil plant expert certification, has now been promoting the use of Construction site. According to the requirements of Well Control Management Rules, it is an effective measure to prevent the occurrence of blowout accidents by injecting workover fluids into the wellbore in time during the downhole operation and maintaining the wellbore pressure greater than the formation pressure. Over the years, the construction of the job by the traditional surface tank and wellhead pressure and submersible pump to complete, there are complicated operation of the construction progress, measurement is not allowed to cause back liquid pollution. The new filling pump is the use of hydraulic machine working machine as a driving force, starting and operating under the tubing through the set to start work, stop working from the start, it automatically stops to achieve synchronous automatic, quantitative rehydration, the wellbore liquid column and out of the tube Equal column volume to ensure that the pressure within the well has always been balanced with the formation pressure to achieve well control requirements. At the same time, the device also has the function of independent operation, which can achieve the functions of waste liquid recovery, tubing pressure test, locomotive and tool oil cleaning, effectively reducing the labor intensity and reducing labor costs and expenses, and are well received by frontline workers.
