Research and practices of re-infill drilling technology for offshore close-spaced cluster-well pads

Jiang Wei(CNOOC Ltd.,Beijing 100010,China)  
The development and application results of offshore overall infill drilling technology charged by the CNOOC as one of major national science technology programs are summarized herein from 3 aspects.First,The overall infill drilling technology was first used for offshore oil and gas fields with great success,which provides a valuable reference for the improvement of EOR and future development efficiency in offshore oil and gas fields.Second,The secondary re-infill drilling was first successfully performed within the already close-spaced offshore cluster wells,particularly some drilling technologies have been improved to a significantly higher level like directional well trajectory control and collision avoidance.c.Third,package of reservoir protection technologies was used for the first time for the high-porosity,high-permeability and low-pressure loose sandstone reservoirs with an obviously satisfactory result.Ever since the above-mentioned achievements were used for the intermediate-and later-stage EOR operation in offshore oil and gas fields,the drilling capability and the management of directional wells have been both improved to a higher degree.As a result,the production of each single well has reached or exceeded its previous rate.Successful field practices demonstrate that the above technologies will help promote the development of offshore oil and gas fields in China and improve the level of the offshore cluster well drilling and directional well drilling technologies.All those achieved results prove that successful trial has been made for future fast development of offshore oil and gas fields and for the improvement of offshore drilling and completion technologies.
