The oilfield safety Hujianshan 83 block of ultra-low permeability reservoirs well network adaptability analysis

Hujianshan oilfield safety 83 blocks long reservoir based on low (low-voltage, low-permeability, low-yielding)is characterized by typical ultra-low permeability oil fields, resource potential, currently controlled by the geological reserves of 130 million tons, but reservesabundance end interbeds relatively developed poor reservoir properties and difficult development, into production wells well productivity. The papers by the structural features of the region, and sedimentary facies characteristics, reservoir characteristics, and six kinds of different development test wells net wells row spacing the inverted nine (rectangle, diamond, square, water fracturing, horizontal wells well net) oil testing, production test, process modification measures is analyzed and compared, to explore a set of suitable length the 7 reservoir reasonable development technology policy, and that the horizontal well in the long Hujianshan oilfield 7 reservoir development better adaptability to provide strong support and guarantee for oilfield Hujianshan's fast on the production.
