horizontal well Manufacturers china is mainly used for the development of carbonate fractured reservoirs, reservoirs with gas cap or bottom water, thin reservoirs, low permeability reservoirs, heavy oil reservoirs and high water-cut artificial waterflood reservoirs.
Its application requirements are mainly reflected in four aspects: one is to greatly improve the oil and gas production of fractured formations by penetrating natural fracture zones; The third is to control the drilling direction according to the distribution of oil, gas and water to reduce water coning and gas coning, thereby improving the oil and gas recovery rate of a single well; the fourth is to improve the efficiency of exploration and development, and for many types of oil reservoirs , horizontal well Manufacturers china drilling can greatly reduce the average drilling density.
Although the cost of horizontal well Manufacturers china is higher than that of vertical wells, the output of non-fractured oil reservoirs is about 3 times that of vertical wells, and the production of oil reservoirs with natural fractures can reach 12 times that of vertical wells. , oil and gas recovery is much higher than that of vertical wells.
