METHOD FOR DETERMINATION OF THE PLACES OF WELL ARRANGEMENT AT SURVEY OF HYDROCARBONS

摘要

Method for determination of the places of well arrangement at survey of hydrocarbons according to which in the course of drilling or according to the data of wells drilled before one determines the upper boundary of ejection danger of rocks. Lower than those boundaries one finds the zones of decompaction of rocks and those are considered to be prospective as to beds of hydrocarbons at presence of gas-resistance layer placed not lower than the upper boundary of the ejection danger of coal layers. The well is arranged in such way as to maximally open the zone of decompaction.
