Abstract

除泥防砂管柱，它由上管柱(1)、降压筒(2)、连接管(3)、沉砂筒(4)和丝堵(5)组成，上管柱(1)下端与降压筒(2)上端相连，降压筒(2)下端通过连接管(3)与沉砂筒(4)上端相连，沉砂筒(4)下端通过丝堵(5)密封，上管柱(4)内设有纵管(61)向下、通过横管(62)与上管柱(1)外相通的上T形管(6)，降压筒(2)内设有纵管(71)向上、通过横管(72)与降压筒(2)外相通的下T形管(7)。它具有过滤效果好不易卡抽油泵、过滤流量大不易堵塞、使用寿命长的优点。

Description

除泥防砂管柱
技术领域
本实用新型涉及石油钻井用管柱。
背景技术
目前石油钻井作业中使用筛管等装置来过滤原油中的泥砂，存在或过滤效果不好容易卡抽油泵，或过滤流量小易堵塞，或使用寿命短的缺点。
发明内容
本实用新型的目的是：提供一种过滤效果好不易卡抽油泵、过滤流量大不易堵塞、使用寿命长的除泥防砂管柱。
本实用新型的技术解决方案是：它由上管柱、降压筒、连接管、沉砂筒和丝堵组成，上管柱下端与降压筒上端相连，降压筒下端通过连接管与沉砂筒上端相连，沉砂筒下端通过丝堵密封，上管柱内设有纵管向下、通过横管与上管柱外相通的上T形管，降压筒内设有纵管向上、通过横管与降压筒外相通的下T形管。
本实用新型的技术效果是：它具有过滤效果好不易卡抽油泵、过滤流量大不易堵塞、使用寿命长的优点。
附图说明
附图为本实用新型实施例剖视图。
具体实施方式
如图所示，它由上管柱1、降压筒2、连接管3、沉砂筒4和丝堵5组成，上管柱1下端与降压筒2上端相连，降压筒2下端通过连接管3与沉砂筒4上端相连，沉砂筒4下端通过丝堵5密封，上管柱4内设有纵管61向下、通过横管62与上管柱1外相通的上T形管6，降压筒2内设有纵管71向上、通过横管72与降压筒2外相通的下T形管7。
使用时将其安装在抽油泵下部，当抽油泵工作时，油流通过上T形管和下T形管进入降压筒，油流在降压筒内压力下降，其中夹带的泥浆、压裂砂和地层砂沉入沉砂筒中，沉降后的油流经上管柱抽出。
