Detailed description of the invention
This oil wells in field hydrogen sulfide administering method, comprises three basic steps: first time detection, dosing, second time detect;
First time is detected particularly: before oil wells in field prepares to carry out operation, important requirement workmen checks whether appliances for labor protection make adequate preparation, protective articles must be neatly dressed, such as: wear cap, mouth mask breathing mask, work clothes, work footwear and rubber gloves etc.Usually ensure to have two workmens at least when entering hydrogen sulfide scene.First enter hydrogen sulfide site operation personnel and must determine wind direction by observation, thus ensure that the process that whole first time detects remains on uptake, ensure the construction safety of workmen.
After wind direction determines, workmen utilizes the associated gas in instrument extraction oil well oil conduit and sleeve pipe, the associated gas that well head extracts is brought back laboratory and carries out simulation laboratory test, simulation well bottom pressure temperature field, sulfur elimination that is dissimilar and variable concentrations all carries out testing and calculating, the sulfur elimination of final every type has a best concentration value, and test effect is best concentration value, the amount of the sulfur elimination required for just adjusting with this concentration value at the scene, and make a record.
After the kind of sulfur elimination and dosage are determined, just can carry out dosing to oil wells in field.First need to enter multi-purpose station to get it filled.Also important requirement personnel inspection appliances for labor protection of getting it filled are needed whether to make adequate preparation before multi-purpose station is got it filled entering, protective articles must be neatly dressed, such as: wear cap, mouth mask breathing mask, work clothes, work footwear and rubber gloves etc., and requiring gets it filled comprehensively checks pump of getting it filled, ensure that machine can normally work.Enter multi-purpose station dosing, first should connect the import and export of pump of getting it filled, the import pipe of pump is inserted in explosive barrel, and outlet tube puts into grug feeding jar mouth, connects power supply, starts pump and starts dosing.
