- Abstract:
-
Tongnanba region is SINOPEC’s mining area in the northern Sichuan Province, daily output is about 3.0×105 cubic meters of natural gas, later mining space is enormous. The research shows that by topography conditions, at present in the gas drilling and region in the basin with more valley, drill in the late in the process of gas drilling will often encounter flash flood debris flow of geologic hazards, serious threat of drill the safe operation, to check up thoroughly flash floods to drill harm degree of debris flow and its development characteristics. The research selected six well locationa in the area from 2010 to 2012 as the study object. Based on researches on the basic characteristics of the valleys in well field, statistical debris flow disaster, the fundamental characteristic parameters in valleys on the premise of summary, the debris flow the cause of formation mechanism, outbreak frequency and the latter scale were summarized. At the same time, from the quantitative aspect, dynamic parameters of the debris in the area was calculated, especially peak flow rate of debris flow parameters value, which provides reference basis for the latter location, prevention and control construction debris flow well site.
