Progress and implications of deep and ultra-deep oil and gas exploration in PetroChina
In recent years,PetroChina has achieved a series of breakthroughs in onshore deep and ultra-deep oil and gas exploration and has discovered a group of large-scale reserve areas,demonstrating enormous petroleum exploration potential.In order to point out PetroChina's future direction of deep and ultra-deep oil and gas exploration,this paper analyzes its recent development situations and new progress in oil and gas exploration.Based on this,the key breakthroughs in deep and ultra-deep exploration are subdivided,and PetroChina's future main petroleum exploration areas are systematically sorted out,ranked and selected.Finally,the exploration experience and enlightenment in different fields is summarized.And the following research results are obtained.First,the deep and ultra-deep reservoirs can be divided into four major domains,i.e.,marine carbonate rocks,clastic rocks and complex litholog ical strata,foreland thrust belt,and deep-strata shale gas.Second,to achieve breakthroughs in deep reservoirs is PetroChina's strategic choice of future focus in oil and gas exploration.It is necessary to carry out hierarchical deployment and highlight the focuses to actively search for large-scale new discoveries and great breakthroughs.Third,PetroChina's four major deep and ultra-deep domains are less explored with large remaining resource potential.Based on the current exploration progress,40 key areas of future oil and gas exploration are preliminarily identified,with 39.4× 108 t OOIP and 39.6× 1012 m3 OGIP,indicating enormous exploration potential.In conclusion,deep and ultra-deep reservoirs are significant practical domains of large-scale oil and gas exploration,and the important measures to speed up the large-scale exploration and development of deep oil and gas reserves include maintaining strategic focus,continuously strengthening technological research and new field exploration,continuously innovating theoretical understanding,and breaking through technical bottlenecks.
