On changes of open porosity in the process of oil fields development

Authors: T.S. Zinovkina (Oil and Gas Research Institute of RAS, RF, Moscow)

Key words: porosity change, estimation of reserves, development of oil fields.

It is concluded that at the establishment of a geological model of the field it is necessary to determine whether the technogeneous impact have effected on the structure and volume of pore space. If it has changed as a result of the deposit development, then at construction of a cube of porosity should take into account changes of the last in the result of technogeneous impact. In accordance with the stages of development of oil fields the classification of the causes of reservoir open porosity change is made. The mechanisms of reservoirs open porosity change are described in the classification.
