China oil network news as of August 7th, Liaohe Oilfield Xinggu 9-5 well realize flowing capacity, average daily output of 70.6 tons, flowing oil for 1563 days, the cumulative oil production of 104 thousand and 600 tons, become the Liaohe oil field after pressure release of 100 thousand tons of production capacity of the first fracture well.
Xing Gu Qianshan block is located in the middle and south part of the western depression of Liaohe depression, and the reservoir is buried 2335 meters to 4680 meters deep. The reservoir type is a massive metamorphic rock fractured Qianshan reservoir with layered characteristics. According to core physical property analysis, the porosity of matrix is generally less than five percent, and the permeability is mostly lower than 1 milli darcy. According to the characteristics of special lithologic reservoirs "low, deep and hard, thick, leakage, Liaohe Oilfield reservoir in high temperature, overcome high fracture gradient, high pumping pressure, high fluid loss, high rate of sand plug fracturing difficulties, to resist high temperature and high pressure, sand plugging, filtration, fast back row of the fracturing process, the maximum improvement of reservoir, natural fracture communication.
This well is 2.3 tons of oil in April 2013 25, April 28, 2013 7 mm choke, flowing production, Nissan 35.6 tons of oil, pressure to achieve the high yield, stable yield a million tons of meritorious wells.
