Yulin Gas Field, The Effective Development Of Low-yield Wells Inefficient Technology

Yulin gas field reservoirs with low porosity and permeability characteristics, with the gradual development of gas field, reservoir pressure decline, the number of low-yield wells, a significant increase in low efficiency. In the production process, due to inefficient low yield lower gas production, liquid carrying ability, often appear wellbore fluid, affecting continuous production of gas and can not give full play to the capacity of these wells. At the same time gas field with low yield, small volume, containing the characteristics of condensate, need to take appropriate matching techniques to exclude the wellbore fluid, improve gas wells, ultimately enhancing the gas when the rate of gas production and oil recovery. This low yield inefficient wells by moving, combining environmental, scientific classification, optimization of gas production system, continuous production of small production, to carry out low-yield wells processes were inefficient domestic research and field application summary, optimization of foam drainage, underground throttle, Air Lift, and assorted Internet technology to improve low-yield inefficient when the rate of gas production wells and the volume contribution, achieve scientific and effective development of such wells.
