China oil network news reporter was informed that in September 1st, 17101 wells in Dagang Oilfield Zhang Sha two section by oil and gas oil test Nissan 100 tons, a high-yield wells Sha two section in the first hundred tons of sprinkler, Chengbei fault step for low reserves use laid the foundation for upgrading.
Researchers in the deposition of innovative thinking, research, in order to break through the southern chengning uplift provenance in small scale, fracture sand control and low breaking the traditional understanding order sand body development, bedding sand supply "is set up, the slope of sand control and sand control mechanism of trough sand rich". Chengbei low fault stage is located in the main phase area of Braided River Delta, with large sand body and good physical properties.
In the accumulation of scientific research personnel, construction of oil and gas migration, multiple reservoir controlling, with advantages of low order fault superimposed contiguous oil reservoir controlling mechanism, the structural trap of oil accumulation correction for the structure and structure lithology and lithologic reservoirs coexist, north-south fault nose oil reservoir can be extended to the contiguous trough area. The formation of the two section of Chengbei low fault terrace is superior in configuration, with the characteristics of oil accumulation as a whole.
Scientific research personnel deployed Zhang Hai 17101 wells in Chenghai 33 wells, the oil test after using 8 mm nozzle flow, average daily output of 89.6 tons, the average daily production of 15 thousand and 800 cubic meters of gas, 102.2 tons of oil equivalent.
