Production Gas Technology of Low Permeable Condensate Gas Reservoir in Pucheng Oilfield Block Pu67

Block Pu67 is low permeable condenstate gas reservoir, construction researchment was developed according to gas reservoir's feature, appling technologes, such as fracturing technology, foam gas technology, flowing back production gas technology, mechanical pumping technology, liquid mitrogen lifing, ranpumping flowing back technology and wellhead bean with ice plug's subsurface flow control technology. This paper introduced effect of these technology and demonstrated advantage or shortcoming.
