Abstract: The assorted production techniques for improving development effectiveness of low permeability fault-block reservoir is a major scientific and technical popularization project for nationwide oil/gas fields development during rear 3 years of the 8th Five-Year Plan determined by CNPC.Huabei Oil Administration Bureau selects l3 low-permeability fault-blocks to implement the project.Over the past 3 years,taking the economic benefit as central task,we draw up the geologic,technological plans and enforcement programs around improving reservoir development results,enhancing oil production rate and increasing recoverable reserves.The development results of 13 fault-blocks have been impoved by applying six sets of production technology.This paper puts forward four proposals for enhancing development effectiveness of similar reservoir.
