Water injection well single well physical unblocking and intelligent remote control measurement and regulation fine separated layer water injection process

Abstract

The invention provides a water injection well single well physical unblocking and intelligent remote control measurement and regulation fine separated layer water injection process, and belongs to thefield of water injection wells. The water injection well single well physical unblocking and intelligent remote control measurement and regulation fine separated layer water injection process comprises the specific steps of water injection well depth measurement and determination, physical unblocking and depth return measurement, bottom layer suction unblocking, underground intelligent water distribution control operation, shaft data remote allocation operation and automatic fine separated layer water injection operation. The process has the advantages of strong unblocking strength, low cost,quick effect, convenience in construction and long validity period, and is a method with an environment-friendly and energy-saving unblocking process technology at present; according to the automaticfine separated layer water injection process, separated layer periodic water injection can be achieved, the influence of interlayer interference on general periodic water injection is avoided, the principle of increasing the recovery ratio through periodic water injection is applied to all oil layers, and the utilization degree of remaining oil of low-permeability zones scattered in the layers isincreased; and the process is high in intelligent control degree, small in operation intensity and high in working efficiency.

Description

technical field [0001] The invention belongs to the technical field of water injection wells, and in particular relates to a single-well physical plugging of a water injection well and an intelligent remote control measurement and adjustment fine layered water injection process. Background technique [0002] In the process of oilfield development, water is injected into the reservoir through special water injection wells to maintain or restore the pressure of the reservoir, so that the reservoir has a strong driving force, so as to increase the production speed and recovery rate of the reservoir. According to the structural form, area size, permeability level, oil, gas, water distribution relationship and the required development index of the reservoir, the distribution position of the water injection well and the relative relationship with the production well are selected (called the water injection method). The well spacing of water injection wells is determined based on t...
