Problems solved by technology

At present, hydrogen sulfide gas sensors are generally used for detection. Since the hydrogen sulfide gas sensor can only detect the hydrogen sulfide content in the air, when it detects hydrogen sulfide gas, the situation is already quite urgent, and sometimes it will cause serious damage due to untimely treatment. security incident

Embodiment Construction

[0009] See attached figure 1 , the present invention places the sulfur ion sensor 1, the pH value sensor 2 and the temperature sensor 3 under the liquid level in the drilling 4, and measures the negative divalent sulfur ion content and the hydrogen ion content in the drilling fluid and the temperature of the drilling fluid, and the sulfur ion Sensor 1, pH value sensor 2 and temperature sensor 3 input the data that is detected into PC 5, and the calculation software of ionization balance and saturated solubility characteristics and the program software that compares the saturated solubility of hydrogen sulfide solution to report to the police are set in PC 5, The built-in software of PC 5 calculates the hydrogen sulfide content of the drilling fluid, and uses the ratio of the calculated hydrogen sulfide content to the saturated solubility of the solution at a certain temperature as the alarm parameter. When the alarm parameter ≥ 1, the PC will be on Before the hydrogen sulfide ...

Abstract

The invention discloses a hydrogen sulfide early-warning measuring method which is characterized by comprising the following steps: using a sensor to detect the contents of sulphur ions and hydrogen ions in drilling fluid and the temperature of the drilling fluid; calculating the content of hydrogen sulfide in the drilling fluid based on the detected data, ionization equilibrium and saturation solubility properties; comparing with the saturation solubility of a hydrogen sulfide solution; and sending out an alarm in time before hydrogen sulfide gas overflows out of the drilling fluid. Compared with the prior art, the early-warning measuring method has the advantages of simple equipment, convenient operation and high early warning accuracy, thereby greatly avoiding personal safety accidents. Thus, the early-warning measuring method has an important significance in preventing hydrogen sulfide overflowing accidents in petroleum drilling industry.

Description

technical field [0001] The invention relates to the technical field of oil drilling gas detection, in particular to a hydrogen sulfide early warning measurement method for oil drilling. Background technique [0002] The overflow of hydrogen sulfide gas in the oil drilling industry is an accident that seriously threatens the life safety of drilling personnel. At present, hydrogen sulfide gas sensors are generally used for detection. Since the hydrogen sulfide gas sensor can only detect the hydrogen sulfide content in the air, when it detects hydrogen sulfide gas, the situation is quite urgent, and sometimes it will cause serious damage due to untimely treatment. security incident. Contents of the invention [0003] The object of the present invention is a kind of hydrogen sulfide early-warning measuring method designed for the deficiencies in the prior art, it observes the content change of hydrogen sulfide in the drilling fluid by detecting the content of sulfur and hydro...
