Abstract

The utility model relates to a direct-reading liquid level alarm used for metering and indicating the content change of drilling fluid in a drilling fluid circulation tank. The alarm comprises a base, an upright post guide rail beam, a buoy, a float rod, a direct reading ruler, an air source pipeline, a pneumatic control valve, a pneumatic control valve touch block, an alarm horn, a guiding and stabilizing cylinder, etc., wherein the direct reading ruler is arranged on the side surface of the upright post guide rail beam and the air source pipeline, the pneumatic control valve and the alarm horn are mounted on the side surface of the upright post guide rail beam; the pneumatic control valve touch block and an indication pin are arranged on the float rod; and the buoy is positioned in the guiding and stabilizing cylinder. When the liquid level reaches the upper or lower limit, the pneumatic control valve touch block on the float rod props open the switch of the pneumatic control valve to sound the alarm horn. The alarm is convenient to mount, can quickly and accurately measure the slurry amount change, and find out circulation loss and overflow in time.

Description

Direct-reading liquid level alarm
Technical field
The utility model relates to a kind of direct-reading liquid level alarm, be mainly used in drilling well liquid measure increase and decrease in metering and the indication circulation of drilling fluid jar, and when drilling fluid increase and decrease amount reaches the bound of setting, carry out alarm, belong to the measuring apparatus of petroleum drilling well site circulation of drilling fluid jar usefulness.
Background technology
At present in the wellbore construction process, obtain the method for circulation of drilling fluid jar drilling well liquid measure increase and decrease, adopt manually measured mud liquid level variation in the circulating tank with ruler more, and then calculate the increase and decrease amount of drilling fluid volume, there is artificial error in dipping in this metering method, and untimely etc. factor is calculated and is monitored in frequent measurement, often make the workmen can not in time understand drilling well liquid measure increase and decrease situation, can not accurately judge overflow, abnormal conditions such as leakage, incur loss through delay the best opportunity of in time taking measures, caused leakage, well kick, the generation of drilling complexity accidents such as blowout.
The utility model content
The purpose of this utility model is to provide a kind of direct-reading liquid level alarm, can accurately measure and indicate mud volume increase and decrease in the circulation of drilling fluid jar, can also in time find abnormal conditions such as overflow, leakage, blowout, sends warning.Overcome the deficiency of metering method in the past, the drilling complexity accident of avoiding so causing.
The utility model adopts following technical scheme, it is a kind of direct-reading liquid level alarm, by base, the column guide rail beam, floating drum, fly rod, the direct-reading chi, source gas line, scavenging air valve, Pneumatic valve, Pneumatic valve touching piece, alarming horn and guiding are set upright tube and are constituted, it is characterized in that the column guide rail beam is vertically mounted on the base, column guide rail beam side is provided with the direct-reading chi, on the column guide rail source gas line is installed, Pneumatic valve and alarming horn, scavenging air valve is installed in the gas source inlet place of source gas line, Pneumatic valve is installed in the upper and lower bound position that the direct-reading chi is provided with on the column guide rail beam, fly rod is installed in the floating drum top, fly rod is provided with on the Pneumatic valve, under touch piece and pointer, floating drum place the guiding set upright in the tube.
Column guide rail beam one side studs with the direct-reading chi that converts and obtain according to by circulation of drilling fluid jar actual volume, and the direct-reading footage number is annotated mud amount (unit: m 3) and liquid level (unit: cm) also corresponding mutually; In order effectively to understand the mud variable quantity, at column guide rail beam opposite side mud amplitude of variation scale is installed, be used for accurately in time understanding the mud variable quantity.
Column guide rail beam, floating drum, fly rod adopt stainless steel material to make, and the column guide rail beam studs with the direct-reading chi, and the scale mark of direct-reading chi uses fluorescent material to make, for night metrological personnel convenience is provided.
Scavenging air valve is used to control bleed pressure, and Pneumatic valve is connected with source gas line, accessory safety, reliable, easy accessibility.
The purpose that being provided with leads sets upright tube is that the wave of avoiding floating drum produced by the stirrer stirred slurry disturbs, influence measuring accuracy, guiding being set setting upright tube and make the floating drum circle float over guiding to set upright in the tube, floating drum only changes mobile up and down with the mud liquid level, avoided floating drum to swing.
Rig-site utilization the utility model is installed in the circulation of drilling fluid tank top with direct-reading liquid level alarm by its base, and guiding is set upright tube and placed on the madial wall of circulation of drilling fluid jar.When the drilling well liquid measure increases, floating drum rises with the mud liquid level in the circulation of drilling fluid jar and moves upward, fly rod on the floating drum and pointer also upwards slide along the direct-reading chi thereupon, pointer is indicated the height and the volume of tank level simultaneously on the direct-reading chi, when arriving, goes up in limited time liquid level, upper limit Pneumatic valve on fly rod touching piece upwards backs down the Pneumatic valve switch, the alarming horn warning of blowing a whistle; When the drilling well liquid measure reduces, floating drum descends with the mud liquid level in the circulating tank and moves downward, be connected fly rod on the floating drum and pointer also thereupon along the direct-reading chi to lower slider, pointer is indicated the height and the volume of circulation tank level simultaneously on the direct-reading chi, when dropping to the following of setting, liquid level prescribes a time limit, lower limit Pneumatic valve on fly rod touching piece backs down the Pneumatic valve switch downwards, the alarming horn warning of blowing a whistle.
The data that the utility model is simple in structure, installation is convenient, can measure the mud volume fast and accurately, mud amount changes so that in time find leakage and overflow, are sent warning.
