Abstract
The invention discloses a method for determining hydrogen sulfide content in black formation water of high-sulfur gas field, which belongs to the field of chemical substance determination. The method comprises the following steps: preparing test reagent according to GB/T11060.1 and connecting test devices; sampling the water sample of black formation water of the high-sulfur gas field, adding the water sample to a distillation flask, and immediately connecting the distillation flask with the inlet of an absorber through a rubber pipe; slowly heating the distillation flask until liquid in the distillation flask is evaporated completely; and determining hydrogen sulfide content in black formation water of the high-sulfur gas field according to GB/T11060.1. The method disclosed by the invention can accurately determine hydrogen sulfide content in black formation water of the high-sulfur gas field, with the advantage of less error.
Description
Technical field
The present invention relates to the assay method of hydrogen sulfide content in the black local water of a kind of high sulfur-bearing gas field.
Background technology
In the reality in the local water in many high sulfur-bearings gas field because of black in color such as asphaltenes and colloidal particles; The mensuration of the hydrogen sulfide content in its local water does not also have truly feasible method; The oil field is on-the-spot generally to filter out the atrament in the local water through manual work; Measure with the colourless water after filtering, because a large amount of sulfuretted hydrogen volatilizees in the process of filtering or is adsorbed in bituminous matter and the colloidal particles, it is very big therefore to measure the error of coming out again.
Summary of the invention
To above-mentioned weak point, the present invention provides the assay method of hydrogen sulfide content in the black local water of a kind of high sulfur-bearing gas field, and this method can be measured the content of sulfuretted hydrogen in the black local water of high sulfur-bearing gas field accurately, and error is little.
The present invention quotes in full GB/T 11060.1 (mensuration of hydrogen sulfide content in the rock gas, 1998).
The technical scheme that adopts: the assay method of hydrogen sulfide content in the black local water of a kind of high sulfur-bearing gas field may further comprise the steps: configure test drug by GB/T 11060.1, and connect test unit; Get high sulfur-bearing gas field black local water water sample, pour in the distilling flask, and connect flask mouth and absorber inlet with sebific duct immediately; Slow heating distilling flask, the liquid evaporate to dryness to the flask; Press the content that GB/T 11060.1 measures sulfuretted hydrogen in the black local water of high sulfur-bearing gas field.
[0006As preferably, said high sulfur-bearing gas field black local water water sample is about 10ml.
Inventive principle and beneficial effect:
The inventor adopts high sulfur-bearing gas field black local water is distilled in flask; The water vapour of band hydrogen sulfide gas gets into the mensuration that the absorber inlet carries out hydrogen sulfide content through sebific duct during distillation; Because of overall process all is in sealed environment, to carry out; So just can not cause the loss of sulfuretted hydrogen, so measuring accuracy is high, error is little.
Description of drawings
Fig. 1 is an experiment flow synoptic diagram of the present invention.
Embodiment
To combine accompanying drawing that the present invention is described further below.
The assay method of hydrogen sulfide content in the black local water of high sulfur-bearing gas field, this method step is following:
1. configure test drug by GB/T 11060.1, and connect test unit.
2. get about the black stratum water sample 10ml of high sulfur-bearing gas field, pour in the distilling flask 2, and connect distilling flask 2 bottlenecks and absorber 1 inlet (as shown in Figure 1) with sebific duct 3 immediately.
3. slowly heat distilling flask 2; Liquid to 2 li of distilling flasks closely dried (preferably evaporate to dryness) is dissolved in the sulfuretted hydrogen in the black local water of high sulfur-bearing gas field and is adsorbed on that bituminous matter in the black local water of high sulfur-bearing gas field is volatilized with the sulfuretted hydrogen on the colloidal particles fully and desorption comes out to be absorbed by acetic acid zinc solution with guarantee.
4. press GB/T 11060.1 and measure hydrogen sulfide content.
Experiment 1
Get high sulfur-bearing gas field black stratum water sample 10.90ml, measure by the assay method of the present invention's protection, it is following to measure the result:
[0019]The contrast experiment 1
Get and test 1 identical black stratum, sulfur-bearing gas field water sample; Artificial filter method by the oil field field by using is measured, and measuring method is following: get black stratum, sulfur-bearing gas field water sample 50ml, repeat to filter with tapered funnel; A filter paper is once changed in every filtration, becomes colourless up to filtrating.Get the colourless local water 11.20ml after the filtration then, add in the 50ml acetic acid zinc solution that configures by GB/T 11060.1, carry out hydrogen sulfide content by GB/T 11060.1 again and measure.
Mensuration result is following:
.
Claims (2)
1. the assay method of hydrogen sulfide content in the high sulfur-bearing gas field black local water may further comprise the steps:
Configure test drug by GB/T 11060.1, and connect test unit;
Get high sulfur-bearing gas field black local water water sample, pour in the distilling flask, and connect distilling flask bottleneck and absorber inlet with sebific duct immediately;
