The fractional volume of the reservoir sand shall be taken to the ground when the crude oil is brought up from the ground. With the deepening of the oil extraction the sand content of oil recovery is increasing. Although many measures have been used such as prevent sand, block sand and so on, the viscosity of heavy oil is big and the fractional of sand is carried into the crude oil gathering system inevitably, causing a series of problems at ground equipment, having a serious impact on the normal production and gathering of crude oil. The larger size of sand can be removed by the sedimentation and the smaller sand can be removed by hydrocyclone devices. Hydrocyclone is a separation plant used to separate non-uniform phase mixtures. It can be used to complete the liquid clarification and to wash particles, liquid degassing and grit removal, grading and classification of solid particles and the separation of two non-miscible liquids and others. Hydrocyclone separation technique is simple and convenient operation, high separation efficiency, no rotating units, small size and easy to realize automatic control. On the offshore platform, if the sand mixed with oil is discharged into sea unsatisfactory the standard, it will pollute the sea. It will cause a serious of marine pollution; this is a problem that should be solved quickly. This paper discusses the requirements for the design of the hydrocyclone desander equipment with compact structure, applicable to offshore drilling platforms, and carrying out CFD simulation, the results showing that the particle size of 75 of sand, grit removal efficiency above 90%.
