Method for water distribution by sound wave remote control

Abstract

The invention discloses a method using sound waves for water distribution of layer separation in a remote way, including the following steps: a, an intelligent water pipe column of water distribution is designed for descent: according to the parameter of a well condition, the pipe column of water distribution of layer separation is designed, a pipe column of water injection is connected with a water well anchor, and a plurality of sets of a short joint, a water blockage packer, a short joint, an intelligent water distributor and a short joint of sequential series connection are combined and connected to be assembled into a whole under the water well anchor; b, the water blockage packer is set: hydraulic pressure is pumped on the well hole to set the water blockage packer; c, distributing injection is prepared: ground equipment is used for pouring water into an oil pipe until the liquid level reaches the well hole; d, the command of layer separation and distributing injection is sent by a sound-wave generator on the well hole by the method using the sound-wave technology for controlling the underground action in a remote way on the ground, the command is transmitted to the underground, and after receiving the command, a sound-wave signal detector of the intelligent water distributor executes the action required by the command to realize the accurate water distribution of a separated injection well. The invention has reasonable design and reliable construction technology, and is the ideal method for the distributing injection of at least one water injection layer of the water injection well of the oil field.

Description

Technical field [0001] The invention relates to a technology for layered water distribution of water injection wells, in particular a method for remote control of layered water distribution using sound waves, which is widely used in oil field water injection wells for layered water distribution and water injection, effectively solving the problem of distribution of separate injection wells, So as to realize the economical and efficient development of oil fields. technical background [0002] At present, as the development of most old oilfields enters the middle and later stages, the natural production decline is serious, the contradiction between layers is prominent, and the development cost continues to increase. Layered water injection has been paid more and more attention by various oil fields because of its dual functions of oil displacement, water replacement and formation energy replenishment. However, how to realize the optimal distribution of injection according to ...

Problems solved by technology

[0006] In order to overcome the disadvantages of low efficiency, complex operation, high cost and application limitations of the layered water distribution technology adopted in the prior art, the patent of the present invention provides a method of remote-controlling layered water distribution with sound waves. Once the pipe string is lowered, the layered water injection allocation task can be completed on the ground using sound wave remote control without lifting the instrument, and the deployment can be repeated many times
