Abstract

The invention provides an interactive injection-production method of a gas well of a gas storage. The method comprises the following steps that a stratum pressure model is established according to thereal-time radius of a gas reservoir in the gas storage; a well bottom flowing pressure model is established according to the effective permeability and a skin factor of the gas reservoir of the gas storage; and a gas production model for the gas storage is determined according to the stratum pressure model and the well bottom flowing pressure model. The gas production model is obtained via the method, and used to implement gas production on the gas well, peak load shaving can be realized for the gas well timely. Gas supply of the gas well is more reliable and safer, and the gas production cost can be effectively reduced via the method.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a method for alternate injection and production of gas wells in a gas storage. Background technique [0002] Affected by weather factors, urban users’ demand for natural gas varies greatly in different seasons. Usually, the gas consumption is large in winter and small in summer. Row. As one of the means of natural gas storage and regulation, underground gas storage has unique advantages such as large storage capacity, good safety, and low storage and transfer fees. It is currently the main and most economical way of seasonal peak regulation in cities. [0003] The peak shaving evaluation of gas wells in gas storage is different from the development of ordinary gas reservoirs. During its operation, there are both gas injection into the formation and gas production. The whole belongs to the dynamic stage of interactive injection and production. The so-called pea...
