Experimental researches on limits of water influx from formation to well
R.J. BabayevAt the period of increase of need in energy resources in the world, the oil industry of Republic develops dynamically. The most of fields in Azerbaijan are in late stage of development and besides oil the product of wells in these fields contain production water in great amount as well. At the moment, the development of production water in drowned wells of Absheron Peninsula accounts for 95, and from offshore fields in average 75 %. In the composition of developed production water together with oil remain great amount of mechanical and other impurities, which cause environment pollution. Taking into account all mentioned-above, a composition has been developed for limiting of water influx from formation to well. On the basis of laboratory-experimental researches, it was established that the injection of new composition into the formation together with the sharp decrease of permeability by water cause increase of oil recovery factor.
