The oil flooding in Jin 91 block of Liaohe oil production plant in Jinzhou successfully completed the flooding
China Petroleum network news, as of August 7th, the group's major development pilot project "Kam 91 block fire drive" 4 well group successfully completed the transfer drive. At present, there are 21 wells in the test well group, 19 wells are opened, the daily production is 283 tons, and the daily output is 26 tons.
As one of the three technologies for heavy oil conversion development, fire flooding can greatly improve oil recovery, and has an advantage in energy saving and emission reduction. Jin 91 block is located in the southwest of Jin 45 block in Jinzhou oil production plant of Liaohe Oilfield. The water content of the block is 91%, and the water content is higher than 90%, accounting for 67% of the total number of wells. It is a typical watered out reservoir.
Beginning of the second half of last year, the Jinzhou oil production plant fire driving project department, process research institute and Liaohe Oilfield Company, oil production, drilling and other departments to carry out fire driving ignition technology demonstration. Relevant experts and technical staff of more than a dozen drilling hospital after discussion, from the ignition process selection to project formulation, then to ignition column design and construction site, each link batted at Jin 45-12- in March 10th, the final 22 wells more successful ignition. Up to now, 4 injection wells in the well group have all finished the ignition.
Next, the plant will focus on the two phase of the project, exhaust gas desulfurization tower, exhaust gas detection laboratory construction, construction work, and constantly explore, summarize, suitable for fire pumping station management methods.
It is understood that Liaohe Oilfield is suitable for fire driven edge and bottom water heavy oil reservoirs, reserves of about 1.1 tons.
