At present, the proportion of natural gas resources in world energy consumption structures is getting larger and larger, the world oil and natural gas industry has entered the age of large-scale natural gas development, and the efficient development of natural gas resources has become a necessary trend and a necessary route for the development of world oil and natural gas. The natural gas resource potential of China is large, the distribution range is wide, and the natural gas resource exploration in the places such as Ordos basins, Tarim basins, Songliao basins, Sichuan basins and south sea producing areas has important breakthrough. Wherein, the unconventional natural gas resources of the Sichuan basin are most abundant, five oil and gas areas of Chongqing, Shunan, northwest Sichuan, Chuanzhong and northeast Sichuan in Chongqing areas are all buried, and the geological reserves of the natural gas are found by accumulating 172251 multiplied by 10 at present8m3. Wherein, only the three-level reserves (proven reserves, predicted reserves and controlled reserves) of the Yuan-Ba gas field are 1.1 billion cubic meters (11000 multiplied by 10)8m3)。
At present, natural gas reservoirs discovered in China mainly comprise various unconventional natural gas reservoirs such as low-permeability tight sandstone gas reservoirs, carbonate gas reservoirs, volcanic gas reservoirs, shale gas reservoirs and the like. Most unconventional natural gas reservoirs in China generally have the structural characteristics of weak bottom water or no bottom water, and all the gas reservoirs adopt a failure development mode to exploit natural gas. The effective evaluation of the yield stabilizing potential of each gas well of the gas reservoir is an important basis for development and adjustment of the gas reservoir, is an important guarantee for continuous yield stabilization of the gas reservoir, and is the basis for efficient development of the gas reservoir. At present, the gas well yield increasing potential under a gas reservoir failure type development mode is evaluated mainly by qualitatively analyzing the stable yield capacity of a gas well according to a gas well production dynamic curve, and the method is strong in experience and poor in reliability, and cannot realize quantitative judgment of the gas well yield increasing capacity.
