METHOD FOR CONSTRUCTION OF THE CLUSTER SITE HOUSING OF INITIAL WATER SEPARATION Russian patent published in 2016 - IPC B01D17/00 E02D7/22 E02D11/00 E02D15/04 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to equipment for oil industry. Cluster site of the wells is selected, after that the place for construction of the cluster site housing of initial water separation is selected, flow rates of the cluster site development wells and physical-chemical properties of extracted products are measured. Amount of water to be reset on the cluster site, required pump diameter and depth, and a number of bore pits are measured, rotary drilling is performed with direct flushing of clay solution under the conductor. Drilled out rock is collected, is lowered, the conductor made of the tubes is fixed and cementing of annular space is performed, perform rotary drilling with direct flushing of clay solution under the production string, casing pipe is lowered and fixed, cementing of casing pipe string annulus is performed. On the upper part of the casing pipe an adapter is mounted, production trees are installed on inner string and tubular insert, production tree is mounted and hydraulic tests of bore hole at pressure are performed.

EFFECT: invention enables to increase efficiency of the cluster site.
