"Cured" gas well with the introduction of technology in Jilin Oilfield
CNPC news, as of December 31, 2017, Jilin gas field Songyuan gas production plant Wangfu gas field 3 mouth water flooded well has been revived successively through the compressor continuous drainage technology, increasing daily gas volume is 22 thousand cubic meters. The V Longquan gas field 7 wells after successful production, the factory in the water flooded wells re success.
In order to give full play to the production of single well in Jilin oilfield, in early 2017 the introduction of continuous compressor cleanup technology, April 2017 in Longquan selected two V block slobber flooded wells to carry out continuous cleanup test success, daily 15 thousand cubic meters of gas, and then selected 5 wells to expand the scope of testing slobber flooded, all successful. 7 wells daily 55 thousand cubic meters of gas, proves that this technology is fully applicable to Fulongquan gas reservoir water flooded wells production.
Some gas wells in Wangfu gas field of Jilin oilfield produce liquid and wax and have strong reservoir sensitivity. As the formation pressure decreases year by year, the comprehensive management of gas wells is more and more difficult and stable production is difficult. The researchers actively carry out dynamic analysis and research. Taking water flooded well as the breakthrough point, in November 2017, we applied continuous continuous drainage technology of compressor, and deployed 3 production wells such as Cheng 2-7 well and so on to carry out the promotion test. Two sets of equipment were used to implement the aid drainage, and the effect was remarkable.
Next, Jilin oilfield will carry out low output, low efficiency and potential survey of remaining wells in other gas areas. It will focus on low return rate and static and dynamic wells. It will strive to resume production capacity and provide technical support for winter supply.
