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

井下智能堵水阀 Underground intelligent blocking valve

本发明是油田采油过程中,为堵塞井下油层出水而设计的一种井下新工具。 The present invention is a downhole oilfield tool new process for clogging underground water reservoir designed.

在采油过程中,因不断对地层注水驱油,导致油层出水,因此就要将水层堵塞,让其出油不出水,使水能起到驱油的目的,这一工程是采油工艺中的一大难题,本发明的目的就解决这一难题的。 In the process of oil production, due to the continuous water flooding of the formation, resulting in the water reservoir, thus clogging the aqueous layer is necessary, let the oil no water, so water can serve the purpose of flooding, the process of oil recovery project is a major problem, an object of the present invention to solve this problem.

本发明是这样实现的,本发明根据水与油的不同密度产生的浮力不同,使本发明的浮子开关处于不同的开关位置,当油层完全充满水时,浮子被浮起,关闭阀孔堵塞水流入油管中,当油层充满油时,浮子下沉,打开阀孔,油流入油管中。 The present invention is achieved, the buoyancy of the present invention is different depending on the density of the produced water and oil, the float switch of the present invention in different switching positions, when the reservoir is completely filled with water, the float is floating, the water shut-off valve clogging inflow tubing, when the reservoir is full of oil, the float sinks, the valve hole is opened, the oil flows into the tubing. 因此实现了堵水而不堵油的目的。 Therefore, to achieve the purpose of water shutoff not blocking oil.

本发明的具体结构由以下附图及实施例给出。 Specific structure of the present invention is given by the following drawings and the embodiments.

图一,是根据本发明提出的井下智能堵水阀的剖示图图二,是本发明提出的井下智能堵水阀的安装位置图下面结合附图详细说明本发明提出的装置细节及工作情况:由附图一看出该发明包括:上主体1;导液阀孔2;上渗液孔3;下渗液孔4;油管连接扣体5;尼龙凡尔6;游动密度浮子7;浮子护体8。 Figure it is a cross-sectional view illustrating the valve plug in accordance with the present invention proposed a downhole intelligence II illustrates details of the apparatus of the present invention is presented in detail and the operation of the present invention proposed intelligent downhole valve plug mounting position DRAWINGS FIG. : a seen from the drawings the invention comprises: a main body 1; catheter valve hole 2; the effusion hole 3; in exudate hole 4; tubing connector buckle body 5; versene nylon 6; 7 swimming density float; float body care 8.

由附图二看出:油管9;套管10;抽油泵11;上封隔器12;油层13;下封隔器14;本发明15。 Seen from the two figures: 9 tubing; casing 10; suction pump 11; upper packer 12; 13 reservoir; lower packer 14; 15 of the present invention.

具体实施时,本发明安装于图二所指的位置,封隔器12、14,将本发明封隔在油层13之中,当油层充满油液时,根据油液的密度小于1,浮力不能浮起游动密度浮子7,此时游动密度浮子7下沉,离开导液阀孔,打开油液通道,当抽油泵上抽时将油液抽入油管中,当抽油泵下行时,尼龙凡尔6回落封堵导液阀孔2,防止油液倒流油层。 During specific embodiment, the present invention is mounted in a position referred to in Figure II, packers 12 and 14, the present invention is a packer in the reservoir 13, when the reservoir is filled with fluid, depending on the density of the oil is less than 1, the buoyancy can not be floating swimming density float 7, this time traveling density float 7 sinks, leaving the catheter valve hole, the oil passage is opened when the pump pumping the fluid pumped into the tubing when the pump down, nylon 6 versene down valve hole plugging catheter 2, to prevent reverse flow reservoir. 当油层充满水时,根据水的密度等于1,浮力浮起游动密度浮子7,此时游动密度浮子7上浮,封堵导液阀孔2关闭通道,当抽油泵上抽时不能将水抽入油管中。 When the reservoir is full of water, equals 1 according to the density of water, the buoyant density float swimming float 7, this time traveling density float float 7, plugging catheter valve hole closes the passage 2, when the pump is not pumping water pumped into the tubing. 因此起到了通油堵水的作用。 Therefore play a role through the oil water shutoff. 本发明是目前油田采油堵水最先进的技术装置,安装容易运行可靠。 The present invention is oilfield water shutoff devices the most advanced technology, reliable and easy to install.
