Title:
METHOD FOR DEVELOPMENT OF A BOTTOM-WATER HYDROCARBON FIELD AND FOR HYDROCARBON EXTRACTION BY MEANS OF A BOTTOM-HOLE SEPARATE RECEPTION GEARED PUMP
Document Type and Number:
WIPO Patent Application WO/2005/119005
Kind Code:
A1
Abstract:
The invention relates to the oil industry, in particular to methods for developing bottom-water hydrocarbon fields and for extracting hydrocarbons by means of bottom-hole geared pumps. The inventive method consists in disposing a geared pump in such a way that the input hole of a liner is placed below the bottom of the formation, in preliminary destroying a water cone in a bottom-hole formation zone by pumping out water through the liner which is connected to the lower suction valve of a cylinder and along the casing annulus through the side suction valve of a cylinder, in evaluating the beginning of the water cone destruction by a hydrocarbon content in a pumped out liquid, in continuously pumping until the substantial or complete destruction and washing of an emulsion formed in a heterogeneous porous rock on a hydrocarbon-water boundary and the separation of the water and hydrocarbon flows are attained, and the initial water-hydrocarbon contact is brought into the initial position. Afterwards, the water is pumped out through the liner and the hydrocarbon through the casing annulus.
