Research on the Development Technical Policy of Low Permeability and Low Abundance Gas Reservoir in Shenmu Gas Field

Abstract

In order to develop the Shenmu gas field efficiently, the development technology policy of Shenmu gas field was studied, including rational partition of layer series, the abandonment condition, and the reasonable production proration. The results show that the Shanxi Fm and Taiyuan Fm of Shenmu gas field gas reservoir can adopt a series of strata to product. The abandonment production rate of single well is 0.2×104m3/d. The abandonment formation pressure in Shenmu gas field is 5.29-5.44Mpa.For the present well spacing of 151 wells and the wellhead pressure of 5Mpa, the corresponding production scale can’t be greater than 12×108 m3/a. For the lowest wellhead pressure of 2MPa, the corresponding production scale should not be greater than 14×108m3/ year.
