Abstract
An integrated logging sample gas purification device is used for the purification of the sample gas of the integrated logging instrument in a gas drilling and relates to the manufacture technical field of the purification device of the integrated logging sample gas in the gas drilling. The utility model consists of a dry-wet two-time deduster composed of a dust filter and a filter water tank, solves the problem caused by the sample gas collecting of the integrated logging instrument because the well mouth of the prior art has a plurality of sample gas dust, in particular to the problem of that the non-exact gas measuring analysis caused by that the dust produced in the implementation of the gas drilling blocks the gas sampling pipeline, the integrate logging sample gas purification device is characterized in that the gas returned from the well can be exactly analyzed; the utility model also provides the installation position for the sulfureted hydrogen sensor and can online detect the sulfureted hydrogen gas appearing in the drilling process.
Description
Technical field: a kind of compound logging sample air purifying apparatus, be used for the purification of gas drilling comprehensive logging instrument sample gas, relate to the manufacturing technology field of the purifier of compound logging sample gas in a kind of gas drilling.
Background technology: in the oil drilling exploration operation, utilize comprehensive logging instrument that down-hole formation natural gas and sample gas are carried out on-line monitoring, find oil gas and the purpose of monitoring pernicious gas thereby reach; In the conventional drilling operation, the extraction of comprehensive logging instrument sample gas, being the formation gas that will carry from drilling fluid separates from drilling fluid under the environment of centrifugal, negative pressure, then by purify, dry operation, import comprehensive logging instrument analysis at last by the road; In order to satisfy continuous growth to the oil demand amount, late nineteen nineties begins a large amount of using gases and implements quick drilling technology as the drilling well medium, but in gas drilling, because drilling well medium fluid structural reform is for gas, so comprehensive logging instrument obviously is difficult to the gas sample is gathered with original sampling technology, simultaneously because gas drilling, the sample gas dust that returns out from well head is many, bring more problem for the collection of comprehensive logging instrument sample gas, particularly the dust of gas drilling generation often stops up gas production pipe, and maintenance difficulties is big, and because the dust in the sample gas, make the gas cls analysis inaccurate, also influence monitoring pernicious gas.
Summary of the invention: the purpose of this utility model is the problem that exists at prior art, utilizes the technique device of doing, wetting twice dedusting, designs a kind of compound logging sample air purifying apparatus with dry dust filtration and water filtration.
The compound logging sample air purifying apparatus that the utility model proposes is made up of dust filter unit, transition water pot, hydrogen sulfide sensor Buffer Pool, drying; The sample gas that is come by well head is connected to dust filter unit through valve by pipeline, dust filter unit is provided with two valves, one is connected with the transition water pot by pipeline, and another is connected with the hydrogen sulfide sensor Buffer Pool, between transition water pot and drying pipeline connection is arranged; The workflow of sample gas is: the sample gas that is returned out by well head is introduced into dust filter unit through valve, in dust filter unit, dust in the sample gas that well head returns out is filtered, sample gas behind the filtering dust divides two-way, one the tunnel flows to the hydrogen sulfide sensor Buffer Pool provides sample gas for the monitoring of hydrogen sulfide, another road flows to the micronic dust in the transition water pot filtering sample gas, the sample gas of removing micronic dust then is input to drying behind the gas outlet through transition water pot top, steam in the sample gas is carried out drying, dry later gas is exactly qualified sample gas, is imported in the instrument and analyzes.
Advantage of the present utility model and beneficial effect are: dust a large amount of from the gas that the down-hole is returned out once filter in dust filter unit, oarse-grained dust here is removed, in the transition water pot, the gas that has less dust granules is here by the thorough wash clean of the water in the jar, the back be dried then as sample gas, can guarantee the accurate analysis of gas analytical instrument returned out from the down-hole like this, in time find the down-hole occurs in the drilling process hydrogen sulfide containing gas and other gases, this device also provides the installation site for hydrogen sulfide sensor, the H 2 S-containing gas that occurs in can online detection drilling process.
Description of drawings:
Fig. 1 is the connection diagram of each parts of the utility model.
The specific embodiment: provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing: the utility model comprises dried, wet two parts filtering and purifying, is made up of dust filter unit 3, transition water pot 8, hydrogen sulfide sensor Buffer Pool 1, dryer 6; Sample gas by well head pipeline 12 is connected to dust filter unit 3 through ball valve 11 by pipeline, dust filter unit 3 is provided with two by- pass valve controls 4 and 13, by-pass valve control 4 is connected with transition water pot 8 through piping 10, by-pass valve control 13 is connected with hydrogen sulfide sensor Buffer Pool 1, is connected by pipeline between transition water pot 8 and dryer 6; The workflow of sample gas is: the sample gas that is returned out by well head pipeline 12 is introduced into dust filter unit 3 through ball valve 11, and the dust in dust filter unit 3 in the gas is filtered; Sample gas behind the filtering dust divides two-way, one tunnel process by-pass valve control 13 flows to hydrogen sulfide sensor surge tank 1, hydrogen sulfide sensor 2 is installed on hydrogen sulfide sensor surge tank 1, test point as hydrogen sulfide on-line monitoring in the drilling process, another road connects the bottom of transition water pots 8 tank bodies through by-pass valve control 4, enters gas in the transition water pot 8 by the micronic dust in the filtering gas; Transition water pot 8 is transparent airtight containers, water inlet 7 is arranged at its top, the bottom is taper, be provided with leakage fluid dram 9, the bottom of transition water pot 8 also can be semicircle, so that clean, bottom leakage fluid dram 9 also can be used as liquid-phase chromatographic analysis the passage of taking sample is provided, and the distance of the installation site of transition water pot 8 top water inlets 7 and transition water pot 8 tank tops is 10mm; Gas is removed the micronic dust in the gas in transition water pot 8, be input in the dryer 6 behind the gas outlet, top of sample gas through transition water pot 8 then the steam in the sample gas is carried out drying, dry later gas is exactly qualified sample gas, is imported in the analytical instrument 5 and analyzes.
