To solve the problem, a lot of theoretical research and experiment have been conducted in selection of sand control screen, sand control methods, underbalanced perforating technology, and frequency-variation pump activation.

According to the fact of Bohai heavy oil reservoirs,some exploitation methods which can be used to improve the single well production with reasonable sanding are presented in the paper,and experimental researches are done.

Reasonable sanding has been the main technology in the middle-late period of oilfield development.

Foreign application examples have proved that the producing with reasonable sanding can increase largely the well production.

Laboratory simulation study of the influence of reasonable sand production on reservoir physical properties and pore structure parameters;

Through optimizing output and productivity,reasonable sand production exploitation decides optimal production measure between sand prevention and sand production.

NB35-2 oilfield is taken as an example and a conclusion that metal kapok screen pipe is more suitable to reasonable sand production in open well completion through a series of simulation experiment as gravel pack completion,metal knit net screen pipe completion and metal kapok screen pipe completion is obtained.

A new theory of adaptable and expandable sand control was put forward,and the basic structural of adaptable and expandable sand screen was introduced,and its expandable principle and construction technology was analyzed.
