Success of low cost acid system test in Tuha Oilfield

Success of low cost acid system test in Tuha Oilfield

Page view

  China Petroleum Network News reported in January 18th that the low cost acid solution system of well Yu 5-23 was successfully used for blocking construction. The highest pressure of acidification in this well is 42 MPa, and the pressure drops to 26 MPa after the acid solution enters the reservoir, and the effect of depressurization is remarkable.

  Jade well 5-23 new wells put into production in October 2013 October 2014 Zhuanzhu, total 48 thousand cubic meters of water after underinjection, the injection pressure of 36 MPa, with injection of 45 cubic meters, 22 cubic meters of real note. After receiving the construction plan of the well, the technical personnel analyzed the difficulties in the construction according to their physical conditions, and at the same time, in order to reduce the cost and increase efficiency, we decided to carry out the plugging test of water base polymer flooding, viscosity reduction emulsified acid and dilute hydrochloric acid in the well.

  Well Yu 5-23 began to acidification in January 8th this year, and the first layer of acidification was completed on the 9 day. During the construction period, technicians and supervisors stare at the construction trend, strictly enforce the construction design and successfully complete the construction. At present, the water injection pressure is 20 MPa, and the injection volume is 45 cubic meters, so that we can understand the blocking requirements. The acid system, the acid cost is reduced by 50%, single well saving acid fee of 68 thousand yuan for lukqin underinjection wells governance provides a new idea.
