Abstract

The invention provides a preparation method of CB (acetylene black)-filled HDPE (high-density polyethylene) conductive foam for a seepage electric simulation experiment and a cutting treatment method for the electric simulation experiment. Experiment equipment consists of an SK-160B double-roll refining machine, an XLB press vulcanizer, a digital multimeter, a DZF-6050 vacuum drying box, a TM-902C digital thermometer, an analysis and scanning electronic microscope, and a JH-2 numerically-controlled foam cutting machine. Experiment materials comprise HDPE, LDPE (low-density polyethylene), EVA (ethylene-vinyl acetate), CB with average granularity of 45 to 68nm, DCP (dicumyl peroxide), AC (azodicarbonamide), Zn-St (zinc stearate) and white oil. The preparation method has the advantages that the preparation technology is simple, and the cost is low; after later electrothermal cutting treatment, a stratum model for the electric simulation experiment can be manufactured.

Description

technical field

[0001] The invention relates to oil and gas seepage technology, belongs to the field of oil and gas field development, and particularly relates to a preparation method of acetylene carbon black filled high-density polyethylene system conductive foam suitable for seepage electrical simulation experiments and a cutting treatment method suitable for electrical simulation experiments. Background technique

[0002] Hydropower simulation experiment is a method to study the mechanism of fluid seepage in the process of fluid flow, based on the principle of hydropower similarity. Hydropower simulation was invented by Soviet scientists in 1918, and it was applied to the experimental study of seepage mechanics in oil and gas reservoirs in 1933. The hydroelectric simulation device is simple and easy to operate, and the experiment period is short, so it is widely used in the field of oil and gas seepage.

[0003] At present, the experimental research methods of reservoir...
