Observation of drilling cores and casting - sections and the characters of pore structures and permeability of the matrix of the lower - ordovician carbonate in comparing with the lower limit of a reservoir for matrix reveal that the porosity, permeability, maximum pore diameter, saturation and median throat diameter in the matrix with undeveloped fissures, holes and solution pores are far lower than those of a reservoir limit although some micro - pores are developed in the matrix which therefore has no capacity of storing and producing oil - gas
摘要通過鉆井巖心和鑄體薄片觀察，根據下奧陶統灰巖基質的孔滲特徵和孔隙結構特徵，並與基質作為儲層的下限對照裂隙、洞穴和溶蝕孔洞不發育的灰巖基質，發現盡管有微孔隙的發育，但其孔隙度、滲透率、最大孔喉半徑、飽和度、中值喉道半徑等參數值遠低於儲層下限值，基本不具備儲集和生產油氣的意義。 -
However, the performance of these algorithms that are based on linear approximation degrades considerably in highly nonlinear situation. whereas the ekf requires the evaluation of the jacobian to obtain the observation matrix, the cmkf needs it to compute the measurement error covariance. both of them employ linear approximation, and thus linear error is inevitible
論文第四章分析了ekf和cmkf在某些情況下跟蹤性能不理想的原因： ekf需要對量測方程進行線性近似， cmkf在計算轉換測量值誤差的均值和方差時同樣要進行線性近似，因此無法避免線性化誤差。 -
