Abstract

井下智能堵水阀是油田采油过程中,为堵塞井下油层出水而设计的一种井下新工具。该阀根据水与油的不同密度产生的浮力不同,使该阀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。该阀是目前井下最先进的堵水方法。

Description

井下智能堵水阀
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。
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。
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。因此实现了堵水而不堵油的目的。
本发明的具体结构由以下附图及实施例给出。
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。
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。
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。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。因此起到了通油堵水的作用。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。

Claims (2)

1、一种能解决堵塞井下油层出水而设计的一种井下新工具。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。
2、根据权利要求1所述工具，其特征在于根据水与油的不同密度产生的浮力不同，使本发明的浮子(游动密度浮子7)开关处于不同的开关位置，而达到的生产运行所需要的状态。
