Hydrogeological control of flood of gas deposits and wells
Presence and the movement of water at gas-bearing layers are of great importance for investigation, development and operation of gas fields and also for preparation of gas for transport. At investigation and calculation of stocks the main attention is paid to entry static conditions of a vodonosnost (release of gas-saturated and water-saturated layers, coefficient of water saturation of gas-bearing collectors, etc.), and during the developing and operation - to questions of dynamics (to advance of edge and plantar waters, water inflow to faces of wells, removal of water from wells, separation of water in trade constructions). Very important with sufficient degree of accuracy to predict change of all these indicators in use as they are among the major basic data for drawing up the project of development, define a possibility of optimum design of all trade constructions, trouble-free, profitable operation of trade and directly influence gas extraction coefficient.
