It was established that in water motion in microscopic cracks a nonlinear effect depending on the size of crack opening, occurs. It was for the first time revealed that the microcracked effect in cracks in water-crack system, i.e. Jamin effect analogue in the porous medium is the reason of manifestation of abnormal water properties. The critical values of crack opening were defined wherein the above-mentioned changes in the fluid properties are practically disappeared. The established water-cracks effect can be used for increase of acceleration performance of pumping water at vulgar and edge floodings. It is necessary to estimate degree of cracks opening in bottomhole zone via regular research works.
