Principle And Devisal Of QXF36 Model Controller To The Wall Of Well On The Ground

The oil and natural gas are flowed mine produce underground. Along with economy developing all over the world, the oil economy as a part of world economy developed rapidly. This bring widest foreground to oil exploitation especially making hole geologic industry. In the engineering domain of making hole geology, sampling underground is one of its important works. Its mostly instrument is Wall of a Well Control on the ground. In 1940, a sampling instrument of wall of a well begins to generalize and use. We can use it to sampling in the sampling well to validate stratum type. In our country, outdated sampling instrument is devised and manufactured in 1960. It adopted the mode of simulation to survey, register and control producing. Its structure is very simple without control instrument on the ground and underground well, so it mostly depends on operators. Outdated sampling instrument with 4 detonators discharged 2 detonators at a time, so it would result in waste of detonators and repetitious operation in the oil well, and it is low very much in work efficiency. In 2000,for the outdated sampling instrument, people used low voltage to excogitate sampling control instrument, and first time adopted the technique of choosing guns. There were 8 detonators. It discharged 1 detonator at a time to reach 8 aims. So using it economized time and detonators, especially in deep well. Now the model of exploding sampling instrument on wall of a well is used in our country. There are 36 sampling instruments with 36 bundles of dynamite. When control instrument on the ground pitches on a bundle of dynamite, it will be electrified, enkindled and exploded to make the sampling instrument rip into stratum to obtain stratum sample.This text analyses and devises control apparatus of the QXF36 Wall of the well sampling instrument from practical task in the oil fields and manufacture in the corporations. It is made up of voltage switch circuitry, inspecting and testing circuitry, ignition circuitry, display circuitry, etc. It is provided with the functions voltage switch, inspecting and testing, ignition, ammeter and panel display. It works reliably by rule and line. It will be easy to operation and servicing. There will be better benefit for the oil field and manufactory after popularizing.
