Abstract: After more than ten years production of Yaha condensate gasfield, the formation pressure has declined generally, some gas production wells have begun to produce water and wellhead pressure shows a trend of decrease. The wellhead pressure of some wells is lower than the gathering pipeline pressure, so it is difficult to use the energy of the oil well to deliver the oil and gas into gathering pipelines. The successful use of gas-liquid pressure-boosting stimulation technology for single wells has made the Well YH23-1-14 resume production, which was shut-in due to low pressure. The daily increase of oil is 10~13 t/d, and gas production is 4.0~5.0×104m3/d, providing valuable experiences for application of this technology in other similar oilfield.
