Bennian Oil Production Plant many low oil wells, machine-mining efficiency of less than 10%. At present, the majority of oil production plants use tubular pumps for exploitation, the depth of the pump under the pump is affected, the general depth of the underground pump is shallow, at 1400 ~ 1800m or so. For deep wells, the tube pump "out of the reach." In July 2005, the oil extraction plant introduced the rod pump efficient lifting supporting technology, using small diameter series oil pump continuous lifting, small pump deep pumping, pump depth up to 2200 ~ 2300m. The test was carried out in No.4 Mine LJL52-10 well and put into production on August 7, with good results. Re-testing is currently underway in LJL 52-12.
Pole pump new technology breakthrough
June 2005, LJL52-10 wells Nissan 2.1t, Nissan 0.5t, water 76.4%. September 7, LJL52-10 well Nissan 6.2t, 4.5t Nissin, water 26%, liquid 1215m. The reason for this huge change in the well is the use of a rod pump efficient lift supporting technology.
