The reporter learned from Zhejiang Oilfield Company on the 16th that the shale gas horizontal well “Yitan No.1 Well” was deployed by the company in Bajiao Village, Maopingchang Town, Yuan’an County. On the 6th, the ignition test of drainage gas production was carried out successfully and all evaluation indexes were good.
It was learned that the “Yitan No.1 Well”, which was successfully ignited, started drilling in May last year, and finished drilling on March 10 this year, with the actual completion depth of 4679 meters. After the successful ignition of drainage gas production by electric submersible pump, the well has been stable for ten days, and the gas output has exceeded 20,000 square meters per day. With the lowering of wellbore liquid level by the drainage of electric submersible pump, well bore pressure and gas production would be steadily increased, truly realizing a steady and considerable industrial gas flow.
According to the introduction, the electric submersible pump technology has a good effect in drainage of low-pressure shale gas wells in Yuan’an exploration area. From the current gas test situation, it is expected to achieve the economic development effect of 70,000-80,000 square meters per day. (Reporter: Liao Quan; Correspondent: Liu Dan)
