Abstract:

In the development of gas reservoir and condensate gas reservoir, absolute open flow and reasonable deliverability of single well are very important parameters, which directly affects the feasibility of the development of gas well and condensate gas well and the development scale of the whole gas field. There are many parameters that affect the deliverability in gas well and condensate gas well, and some parameters are uncertain. Howto evaluate these parameters is very important for confirming the absolute open flow of gas well and condensate gas well. An analytic method of deliverability parameter based on orthogonal test is introduced, and some important factors that are uncertain are studied and selected. This study provides a newmethod and technical support for deliverability evaluation of gas well and condensate gas well.

Key words: lithologic reservoirs, gravity flow deposit, formation mechanism, development model, inner composition, technique series
