It’s far from the Hainan Wenchang county about 148 km away. The oil field sand phenomenon is relatively serious. Every year oil company takes large spendings on completion and sand control production. The key of Wenchang oil field sand control technology is design the Sand control layer structure of sand control screen and Integrated block off sand control accuracy. At home or abroad designers choose the gravel size according to the D50=(5-6)*d50 as sand control method. After that, they retrodict the block off accuracy of senior high quality screen. But actually, the Sorting types and Sand particle sizes in special oil field’s formation sand are ever changing, at the same time, they differ greatly, we can’t design completely according to the formula. In this text ,according to the analysis on Wenchang 19-1 north oil field’s formation sand screen, designers confirm the gravel pack experimental program and Senior high quality screen sand simulation experiment scheme. After experiment, According to the result of the experiment, collection and analysis, we finally Recommend reasonable block off sand control accuracy. Keywords: mechanical analysis; sand control
