The study and application of the reasonable work system for the condensate gas reservoir of Baimao

The geology structure is complicated in the condensate gas reservoir of Baimao, the lengthways and horizontal variety of the sand body growth is big. The reservoir buries deeply, porosity and penetration coefficient is low, the geologic strata pressure and the dewdrop differential pressures are small, so the well productivity is low and it's hard to get steady production. Since the well has entered into medium period, the water content increases, and influences normal production seriously. Because the technique request of the condensate gas reservoir is high, 14 years passed, it just entered in the regular development period in 2000. The development result was not ideal, natural decrease was up to 27.45% in 2002 and 26.98% in 2003. Since 2004, the staff developed a set of the reasonable work system for the condensate gas reservoir of Baimao, slowed down its natural decrease effectively, which decreased from 26.98 % in 2003 to 19. 13 % in 2004, and brought the condensate gas reservoir of Baimao into good development. At the same time it also provides the reference for similar condensate gas pool development at home and abroad.
