Tight Gas Reservoir

The rational proration is the prerequisite condition of realizing the high gas production and steady production of gas reservoir. Especially to the tight gas reservoir, due to the very low permeability, there are many low yield and low pressure gas wells. Because low yield and low pressure, the gas well is easily effected by the liquid loading and the change of working system, which cause the degree of reserve recovery decrease, more seriously make the gas stop producing directly. Based on the seepage rule in tight gas reservoir and analyzing the every factors influencing the production of low yield and pressure gas well, the low yield and pressure gas well have been classified to several types. And the gas well yields of different type have been optimized.

In order to study the characteristics of the gas supply and development mode in sweet spots of Sulige tight gas reservoir in Ordos Basin, China, a mathematical model was developed for the typical lenticular reservoirs in tight gas reservoirs, and its analytical solution was obtained. The ideal model was calculated by using the analytical solution. Analysis of the production data indicated a clear boundary between the high- and low-permeability regions of the lenticular reservoir, and the boundary will supply gas to the low-permeability region. The reliability of this finding was validated by real production data. The development mode of the lenticular reservoir was obtained, that is the high-permeability area was first used during the initial production; when the pressure wave reached the boundary in the high-permeability region, the production showed a pseudo-steady state; further increase of the production pressure exceeding the threshold of the surrounding low-permeability region triggered the utilization of the low-porosity and low-permeability regions. The established model can provide useful guidance for the development of similar tight gas reservoirs.
