In this work, the electrical resistivity properties of different gas-water-sand fluid were experimentally investigated using the multiphase flow loop and static solution experiments. The effect of gas phase fraction and gas bubbles distribution, sand fraction and sand particle size on the relative resistivity of the multiphase fluid were systematically studied. The measurement devices and operating parameters were also optimized. A novel combined resistivity method was developed, which demonstrated a good effect for the measurement of phase fractions of gas-water-sand fluid, and will have a good application potential in marine natural gas hydrates exploitation.<\/jats:p>","DOI":"10.3390\/e24050624","type":"journal-article","created":{"date-parts":[[2022,4,29]],"date-time":"2022-04-29T16:49:57Z","timestamp":1651250997000},"page":"624","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Investigation of Gas-Water-Sand Fluid Resistivity Property as Potential Application for Marine Gas Hydrate Production"],"prefix":"10.3390","volume":"24","author":[{"given":"Zhiwen","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Gas Hydrate, Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, Guangzhou 510640, China"},{"name":"Guangdong Provincial Key Laboratory of New and Renewable Energy Research and Development, Guangzhou 510640, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100027, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaosen","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Gas Hydrate, Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, Guangzhou 510640, China"},{"name":"Guangdong Provincial Key Laboratory of New and Renewable Energy Research and Development, Guangzhou 510640, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100027, China"},{"name":"State Key Laboratory of Natural Gas Hydrates, CNOOC Research Institute, Beijing 100028, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2743-6811","authenticated-orcid":false,"given":"Zhaoyang","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Gas Hydrate, Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, Guangzhou 510640, China"},{"name":"Guangdong Provincial Key Laboratory of New and Renewable Energy Research and Development, Guangzhou 510640, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100027, China"},{"name":"State Key Laboratory of Natural Gas Hydrates, CNOOC Research Institute, Beijing 100028, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Gas Hydrate, Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, Guangzhou 510640, China"},{"name":"Guangdong Provincial Key Laboratory of New and Renewable Energy Research and Development, Guangzhou 510640, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100027, China"},{"name":"State Key Laboratory of Natural Gas Hydrates, CNOOC Research Institute, Beijing 100028, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Peng","sequence":"additional","affiliation":[{"name":"Key Laboratory of Gas Hydrate, Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, Guangzhou 510640, China"},{"name":"Guangdong Provincial Key Laboratory of New and Renewable Energy Research and Development, Guangzhou 510640, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100027, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sloan, E.D., and Koh, C.A.
