Abstract

Abstract: During the 13th Five-Year Plan period, PetroChina made a number of significant achievements in geological theory and
technological innovation, as well as breakthroughs and discoveries in oil and gas exploration and reserve increase, etc. This paper
reviews and summarizes the company’s oil and gas exploration achievements and theoretical and technological progress during
the 13th Five-Year Plan period and proposes development ideas and strategies for the 14th Five-Year Plan period. During the 13th
Five-Year Plan period, PetroChina highlighted an innovative resource strategy, emphasizing efficient exploration, increasing risk
exploration in new areas and new fields, concentrating exploration on key areas in major basins and fields, and strengthening integrated geological and targeted research. A series of innovative geological theories and understandings were developed and improved,including hydrocarbon accumulation in conglomerate reservoirs in sag areas, hydrocarbon accumulation in large-scale
lithologic reservoirs in shallow water delta, “three paleo” controlling oil reservoirs in marine carbonate rocks, “fault karst” controlling the formation of oil and gas reservoirs in strike-slip fault areas, hydrocarbon accumulation in deep foreland thrust belts,
“four elements” controlling shale oil reservoirs, “three elements” controlling the accumulation and enrichment of shale gas reservoirs,and “three elements” controlling the formation of deep volcanic rock gas reservoirs. A series of exploration and evaluation technologies were developed, such as 3D seismic acquisition, processing and interpretation technology for “double high” and “double complex” areas, drilling and completion technology for deep and ultra-deep formations, well testing technology for deep wells, and volume fracturing technology for long horizontal wells. During the 13th Five-Year Plan period, 34 major breakthroughs were made in the exploration fields of lithologic-stratigraphic reservoirs, marine carbonate rocks, foreland thrust belts, shale oil and gas, mature exploration areas and volcanic rocks in the Sichuan, Tarim, Junggar, Ordos, Songliao, Bohai Bay and other major basins. The historic long-term high-level growth of oil and gas reserves has laid a resource foundation for steadily increasing in oil production and rapid growth in natural gas production. During the 14th Five-Year Plan period, PetroChina will scientifically plan its strategic direction and the focus of oil and gas exploration to promote continuous large-scale increase of conventional oil and gas reserves and rapid development of unconventional resources in six major basins and five fields. The company will accelerate the implementation of large-scale increases in oil and gas reserves, actively prepare strategic replacement areas and major replacement fields, and consolidate the resource foundation for the company’s ongoing high-quality development.
