METHOD FOR DETERMINING PLACES mortgaged production wells while RAZBRABOTKE HYDROCARBONS FIELD

摘要

A method of determining places emplacement wells in the development of hydrocarbon fields comprising drilling exploratory wells within the field followed by coring and holding therein geophysical and seismo studies, the construction of maps reservoir properties of the formation, which is isolated zones most probable development of reservoirs, at designated areas laying the production wells, characterized in that the isolated complex geological genetic regionally with a common p sprostranennym oil and gas bearing horizon with belonging to it investigated portion and the reference deposit on the test portion is conducted exploratory drilling followed by coring and sludge and holding therein geophysical studies, the results of which determine the effective H layer thickness and the effective pore volume by the formula: where H - the effective thickness of the reservoir, measured at the points of its intersection portion of the test wells, K. average value for the formation porosity reference field, objectified elyayut for the reference field threshold value of the effective pore volume V, wherein the collector of the breed of lithology neftegazonosen; of seismic data for the reference field is determined set of dynamic, kinematic, structural attributes of the seismic wavefield, which are used in forming the training sample for the trained neural network based on the values ​​of the effective pore volume Vdlya wells; using a trained neural network is isolated by attribute significance
