—Slim-hole oil recovery technique is
increasingly used in SINOPEC and there are over 220 slim-hole
wells in block-LP at the moment. Meanwhile the dimension of
slim-hole brings several problems such as matching tools,
eccentric wearing, lifting, separate layer recovery and so on.
Through lab experiments and field application test analysis
from block-LP, a mature and effective supporting technology
for slim-hole well has already been summarized. Also special
dimension corollary equipment is under research and
development to meet the need of Slim-hole oil recovery
technique, such as connecting tripping device, oil drain device,
QSA packer, etc. All these special dimension devices are reliable
and have been put into use and running well. All in all, through
practice slim-hole oil recovery technique is cost savings in both
exploration and exploitation, especially in reducing the usage of
steel products. The integration of slim-hole oil recovery
technique, matching process and separate layer recovery technic
will provide certain guiding significance for construction site.
