Abstract: Drilling Institute of Engineering Technology Research Institute under CNPC Greatwall Drilling Company (GWDC) has developed four systematic multilateral well drilling and completion technologies with independent intellectual property rights through a series of study and field practice of multilateral well drilling and completion technologies. These technologies have achieved good development results in practical application, and the objective of "high yield with less wells" has been fulfilled. The four technologies can be greatly used to develop difficult-to-exploit blocks with low cost and high efficiency, tap potential and increase output in old areas, improve producing degree and enhance oil recovery of reservoirs.
