Abstract
This invention relates to a kind of extraction method of pouring water into oil well. This invention technical plan is: installs the single tube column in the well chamber, uses in this well the stratum water upside water level, is airtight turbo-charged pours into in this well the lower part oil layer; The power unit locates upside under the water level filter and pouring layer between the above packer, underneath the power unit's pipeline connection sensor, the sensor the mine shaft pressure, the current capacity signal passes on through the far biography holding wire to the ground in on the control mechanism carries on the control, the adjustment, the demonstration. This invention adapts the common water well, which uses single tube in the flow, uses upside this well by the power unit the formation water, and is airtight turbo-charged after pours into to this well lower part oil layer, and realizes not leaving ground this well and picks the inkstone well water the goal, also it pours water the parameter definitely and may carry on the monitor and the regulation to the ground. The technical process is simple, the performance is advanced, throws transports the cost is inexpensive, but large scale enhances the small sub-area oil-field development the economic efficiency, moreover suitable to oil field common water well water-injection development.
Description
One, technical field: the present invention relates to a kind of oil-extracting well water injection new method.
Two, background technology: for small-block oilfield and outlying wellblock, water flooding regime puts into operation routinely, needs to dig a well, builds a station and lay the line etc., certainly will cause cost of crude oil production too high, low in economic efficiency, even directly influence the whole evaluation of exploiting meaning in such block oil field.
Three, summary of the invention: the purpose of this invention is to provide a kind of oil-extracting well water injection new method, its technological process is simple, and is advanced in performance, and it is with low cost to put into operation, the economic benefit of small-block oilfield exploitation can be increased substantially, and the waterflooding extraction of oil field conventional oil well can be suitable for.
Technical scheme of the present invention is: single time tubing string is installed in pit shaft, is taked the water of the top water layer on stratum in this well, the bottom oil reservoir in this well is injected in airtight supercharging; The power unit is between the strainer and the packer on the implanted layer under the water layer of top, pipeline below the power unit connects sensor, and sensor reaches down-hole pressure, flow signal on the ground controlling organization by the remote transfer signal line and controls, regulates, shows.
The present invention adapts to the conventional oil well, adopts single tube time flow process, take this formation water of aboveground by the power unit, be injected into the bottom oil reservoir of this well after the airtight supercharging, can not realize that ground Ben Jing adopts the purpose of water water filling, and its water injection parameter can monitor in ground and regulate and control fully.Technological process is simple, and is advanced in performance, and it is with low cost to put into operation, and can increase substantially the economic benefit of small-block oilfield exploitation, and can be suitable for the waterflooding extraction of oil field conventional oil well.
Four, the specific embodiment: take the method for perforation to penetrate to drive a well in the tube corresponding top to adopt water layer and bottom oil reservoir, the water filling layer is tail pipe, packer, pressure flow sensor, electric pump unit, is in turn connected into single tube from top to bottom and injects well and hang on the simple wellhead by the socket tubing string.Servicing unit mainly comprises pressure flow display instrument, junction box, frequency converter, electric control box etc.The electric pump unit adopt on top under the water layer between the packer on sand fine filter and the water filling layer, its top is provided with cartridge, every servicing units such as sand fine filters, respectively will be from after the water desanding of this aboveground water layer, filtering, suck by the electric pump unit again, after its airtight pressurization, inject the oil reservoir of this down-hole portion.The electric pump unit is designed to inversion type.The pressure flow sensor is equipped with in electric pump unit exit, its pressure flow signal is reached on the ground pressure flow Displaying Meter by the remote transfer signal line, water injection pressure and water injection rate in order to monitoring downhole electric pump unit, and regulate near it frequency converter in view of the above, just can accurately set up water injection rate, not only satisfy the water injection technology requirement but also reached purpose of saving by the injection allocation requirement.Described sensor can be fixed on the pipeline between power unit and the packer.
