SCORE

Chemical Flooding and Miscible Floodinged. Meanwhile, the percolation characteristic and enhanced oil recovery mechanism of each displacement method are discussed. For miscible flooding, the frequently used miscible phase injectant is introduced. Finally, rough categories and their enhanced oil recovery mechanism of the miscible flooding are discussed.

正式演说

Profile Control and Water Shutoffmula and application scope of various chemical agents are listed. Meanwhile, the importance of profile control and water shutoff is described; rough categories and their enhanced oil recovery mechanism of both methods are discussed.

Acids and Additives Used in Acidizinguch as retardant, corrosion inhibitor, iron stabilizer, emulsion inhibitor, clay stabilizer, cleanup additive, sludge inhibitor, wettability reversal agent and diverting agent, are also introduced in detail in this chapter.

托运

Pour Point Depression Transportation and Drag Reduction Transportation of Crude Oil drag reducing agent. Factors affecting the drag reduction effect of drag reducing agent including the property of crude oil, the structure of drag reducing agent, and the conditions of pipeline transportation are introduced.

Demulsification of the Emulsified Crude Oil and Defoaming of the Foaming Crude Oilal method. The problems of foaming in crude oil are mainly encountered in the process of oil–gas separation and oil stabilization, during which natural gas is released from crude oil by reducing pressure and (or) elevating temperature. Crude oil defoamers including solvent defoamers, surfactant defoamers, and polymer defoamers are introduced.
