New technology in North China Oilfield increases water consumption by 42 thousand tons

Page view

  China Petroleum network news, August 8th, plagued by water out of the North China Oilfield, Shanxi 105-46X well, in the use of modified thermosetting resin plugging water, oil well water content dropped to 81%, 104.4 tons a month oil increase.

  The main reservoirs in Huabei Oilfield have generally entered the high water cut stage, and the flooding problems caused by various reasons have plagued oilfield production. To solve the problem of Huabei Oilfield in high water cut stage, complex fault block reservoir water plugging technology route, according to the complex geological conditions and wellbore conditions, forming a more perfect four water plugging technology system, as well to control water channeling and improve oil production tool. Up to now, Huabei Oilfield has adopted water plugging technology system, has implemented 78 wells on the spot, increased 42 thousand tons of oil.

  For the oil well casing and channeling, technical personnel proposed tube sealing fixed ideas, improve and expand the understanding of technology and method of oil well seal sealing, break through the technical bottleneck, formed by two patents supported by the modified thermosetting resin cementing technology. This technology has been selected as the advantage catalogue of group company.

  For the oil field has entered the high water cut or extra high water cut oil mining, gradually formed in the high permeable channels or large pores, the formation pressure field, streamline field forming mode, dominant flow channels formed between oil and water wells, water flooding caused by the "short circuit", Huabei Oilfield formed the emulsified oil soluble resin selective plugging technology system. For ultra high temperature and ultra deep water plugging demand, forming a high temperature resistant to biological calcium oxide as the main component of the plugging agent, can achieve the temperature of 200 degrees Celsius, 6000 meters deep wells for water plugging; high temperature sandstone reservoir needs, the formation of bio polymer composite gel plugging agent can achieve high temperature resistance, resistance the temperature of 125 degrees celsius.

  The four water plugging technology system has wide applicability, can effectively block the formation of hypertonic with water holes, improve the efficiency of water flooding in low permeability oil, play, seam hole production capacity, to achieve the purpose of increasing oil precipitation.
