On the basis of introducing the advanced technologies from foreign country, a cage-type tuber harvester has been designed.

Based on the study of the gas reserve scale and oil-gas distribution for ordinary heavy oil reservoir with gas cap of Cao 31 fault block in Lean oilfield, using reservoir engineering and numerical simulation, optimizing study on development technical limits for oil reservoir with small gas cap including production method, well pattern, waterflooding time is carried out.

Nine sorts of well patterns for thermal recovery are designed for three types of super heavy oil reservoirs in Shengli petroliferous province.

Optimal well pattern and optimum fractures are the important link of development program,they also play a decisive part in expanding recoverable reserves,recovery factor and production of natural gas.
