Abstract Most of oil fields in China have stepped into the middle or later stage waterflooding life, and wells begin to appear above water. In conventional acid treatment, fluid always flows pore path with high water saturation firstly, broadens filled However, it can't stimulate as well that To solve this problem, especially heterogeneous formation, paper indicates a novel selective emulsified system, which viscosity will increase when meets decrease formation. The core flooding experiment...
Abstract Frequency estimation, one of the key technologies in wireless communication and radar science, has been extensively deeply studied by scholars. Based on a detailed frequency estimation characteristics analysis two existing algorithms (the fixed Quinn algorithm A&M algorithm), this paper proposes new improved high-precision algorithm. The proposed is two-step estimation. In first step, we use to calculate coarse errors, second results from step as initial iteration After...
