The Application of Combination Technology of Jet and Fracture in Mongolia Tamsag Oilfield

Haijun WANG

Abstract


Mongolia Tamsag oilfield formation permeability is low, mainly, it’s all wells need to fracture. Because using swabbing way to remove the fracturing residue can lead the shallow depth and intensity suction, small output of raffinate, slow drainage velocity, it will waste a lot of time. So these problems will lead to the residue cause secondary precipitation pollution for oil reservoir problems. However hydraulic pump quick return process is suitable for Mongolia Tamsag oilfield’s requirements. Meanwhile Tamsag oilfield corollary use fractured jet pump, transduction pump leather, and optimistically choose packers of large drift diameter fracturing. Field application proves that this process can meet the requirements of timely return after fracturing. It not only decreases manual labor intensity, becoming more safe and reliable, but also has obvious advantage in quick withdraw and broken down which efficiently prevent the secondary formation pollution which meets production need.
