Parameter optimization of gravel packing sand control method for natural gas hydrate production

[摘要] According to the research on the method of sand control for oil and gas wells at home and abroad, it was considered that gravel packing sand control method was an effective sand control method for gas well mining. In order to solve the problem of large amount of sand out for natural gas hydrate production, related problems of difficult sand control, that technology was explored of sand control and optimization method that was suitable for mud sand reservoir of natural gas hydrate production. Based on the low pressure strata in the northern South China Sea area of our country, characteristics of low cementation, it was initially chosen particle size of 0.150-0.200mm sand control gravel through theoretical calculation, through it, the best gravel size range was 0.200-0.250mm and the thickness was 40mm.
