Assess offshore heavy oil development by risk analysis;

Aimed at offshore heavy oil reservoir, on the basis of technological feasibility, a new model of developing offshore heavy oil reservoir is presented for more benefits.

The sand removal from sandy oil and purification of oily sand is one of key links to guarantee the normal cold production of viscous oil wells as failure of sand control and the successful application of advanced oil recovery technique such as moderate sand control in offshore viscous oil field.

The essential technology of steam drive for heterogeneous heavy oil reservoir with edge-bottom water;

Secondary recovery of high water-cut conventional heavy oil reservoir;

Secondary development of thick block heavy oil reservoirs in Block Gao246;

Research on Some Flow Characteristics during Water Flooding in Viscous Oil Reservoirs and Improving Development Effects;

On Fine Description and Optimal Development of Viscous Oil Reservoirs in Tankou Oilfield;

On Applying Oil in Water Emulsion to Improve Water Flood Effects of Viscous Oil Reservoirs;

Shortages of serious sand producing,being much thinner of up and down separate layer,fault and complex relationship of water and oil in low layer dense oil reservoir of Shengli oilfield are exist that can not carry out exploration reserve and restrain exploitation seriously.

The crude oil in dense oil reservoir of Tahe oilfield is main of heavy oil which density on general is among 0.

Because of the special geological features of the dense oil reservoir of Block Jin 99(xing)in Liaohe oilfield, some problems have strongly needed to get their solution in the current exploitation.
