Abstract
The down-hole intelligent water-plugging valve is a new ool designed for plugging water exit of air reservoir. According to the different buoyant forces produced by different densities of water and oil the float switch of said valve can be positioned at different positions, when the oil reservior is filled up with water, the float can be floated, the valve hole is closed to plug water flow and prevent it from flowing into oil pipe, and when the oil reservoir is filled up with oil, the float is moved down wards, the valve hole can be opened, the oil can be flowed into oil pipe.
Description
The present invention is in the oil recovery process of oil field, for stopping up a kind of down-hole new tool that down-hole oil reservoir water outlet designs.
In oil recovery process, to the stratum displacement of reservoir oil by filling water, cause the oil reservoir water outlet because of constantly, therefore water layer will be stopped up, allow its fuel-displaced not water outlet, and make water can play the purpose of the displacement of reservoir oil, this engineering is a great problem in the oil production technology, and purpose of the present invention just solves this difficult problem.
The present invention realizes like this, the present invention is different with the buoyancy that the different densities of oil produces according to water, make switch of the present invention be in the different position of the switch, when oil reservoir was full of water fully, float was floated, and close valve orifice is stopped up water and flowed in the oil pipe, when oil reservoir is full of oil, float sinks, and opens valve opening, and oil flows in the oil pipe.Therefore realized water blockoff and not stifled oily purpose.
Concrete structure of the present invention is provided by the following drawings and embodiment.
Figure one, is the cut-away view of the intelligent water blocking valve used under well of proposition according to the present invention
Figure two, are the installation site figure of the intelligent water blocking valve used under well that proposes of the present invention
Describe device details and the working condition that the present invention proposes in detail below in conjunction with accompanying drawing:
Find out that by accompanying drawing one this invention comprises: go up main body 1; Drain valve opening 2; Last liquid-leadage hole 3; Following liquid-leadage hole 4; Oil pipe connects button 5; Nylon valve 6; The density float 7 of moving about; Float watch box 8.
Find out by accompanying drawing two: oil pipe 9; Sleeve pipe 10; Oil well pump 11; Upper packer 12; Oil reservoir 13; Lower packet 14; The present invention 15.
During concrete enforcement, the present invention is installed on the position of figure two indications, packer 12,14, with packing of the present invention among oil reservoir 13, when oil reservoir is full of fluid, according to the density of fluid less than 1, buoyancy can not float the density float 7 of moving about, the density float of moving about this moment 7 is sunk, and leaves the drain valve opening, opens the fluid passage, when taking out on the oil well pump with in the fluid suction oil pipe, when oil well pump was descending, nylon valve 6 fell shutoff drain valve opening 2 after rise, prevents fluid refluence oil reservoir.When oil reservoir is full of water, equal 1 according to the density of water, the buoyancy force density float 7 of moving about, the density float of moving about this moment 7 come-ups, shutoff drain valve opening 2 closing passages can not be with in the water suction oil pipe when taking out on the oil well pump.Therefore played the effect of logical oily water blockoff.The present invention is the state-of-the-art technique device of present oil field oil recovery water blockoff, installs reliable easily.
Claims (2)
1, a kind of a kind of down-hole new tool that can solve obstruction down-hole oil reservoir water outlet and design.Comprise: go up main body 1; Drain valve opening 2; Last liquid-leadage hole 3; Following liquid-leadage hole 4; Oil pipe connects button 5; Nylon valve 6; The density float 7 of moving about; Float watch box 8.
2, according to the described instrument of claim 1, it is characterized in that according to water differently with the buoyancy that the different densities of oil produces, switch is in the different position of the switch to make float of the present invention (density float 7 of moving about), and the needed state of the production run that reaches.
