There is plenty of source rock in Sichuan Basin.Owing to its high evolution,high or over maturity,oil pools only have been discovered in Jurassic,in Triassic or even older beds only dis- covered gas pools.The dominant reservoir is carbonate rock characterized by poor porosity,1.7% on average,and poor permeability,less than 1×10~(-3)μm~2 in common.The average porosity may reach up to 3%~6% in intervals developed with pores and caves.Based on 40 year exploration experience,it is considered that it is a key job of oil-gas exploration in Sichuan Basin to strengthen preliminary exploration and get new discovery.In preliminary exploration,the goals of large- medium size of gas pools are planned according to structural zones,the traps with similar conditions or adjacent location are considered as a whole,carry out wide exploration with very a few wells.Since the eighth-five-year-plan,marked progresses have been achieved in exploration technique of high-steep structural zones and reservoir transversal prediction,which make the exploration results getting better.

四川盆地烃源十分丰富。但油气演化程度高,大多已进入高成熟和过成熟阶段,至今只在侏罗系发现有油藏,三叠系及其更老地层皆为气藏。储层主要为碳酸盐岩,其特点是低孔低渗,平均孔隙度仅1.7%,平均渗透率小于1×10~(-3)μm~2,但其中的“孔洞发育层段”平均孔隙度可达3%~6%。根据四十年的勘探经验,加强预探并争取新发现是四川盆地油气勘探发展的关键。预探中,按构造带规划大中型气田勘探目标,将成藏条件相似、地域上相邻的局部圈闭群作为一个整体勘探对象,实行稀井广探,少井高效。“八五”以来,在高陡构造带勘探技术、储层横向预探技术等方面有长足的进步,勘探成效不断提高,实现了资源序列的良性循环。

The proved natural gas reserves in “Eighth Five Year”and “Ninth Five Year” periods are rising fast.The research on distribution rule of major gas fields can help greatly the proved reserves in cratonic basin.There are two basic theories about the rich gas areas.First is that the uplift is favourable for gas concentration,and second is that non structure trap is profitable areas for gas to move into the cratonic up sequence.Foreland basin is another kind of rich gas basin in China.The rich gas areas are the major structure traps lying in the thrust area,the lithological pinching in the foreland slope,and the fault block traps in the frontal uplift of a foreland basin.After studying much more geological data and learning from correct exploration experiences,the authors try to give useful ways how to screen profitable exploration areas,and selects nine profitable rich gas areas in China,which can do something good to exploration and develoment of China gas industry.

There are seven models of major gas fields in the foreland basins. Distribution of gas rich areas is mainly controlled by the fault fold or rupture. After studying the type of development and distribution characteristics of large medium sized gas fields of each second order structure in the foreland basins, the authors hold...

The natural gas resource is rich in Central and West China. The ratio of proved reserves is only 9.3% in the five gas rich basins there the natural gas exploratin potential is large. There are seven models of major gas fields in the foreland basins. Distribution of gas rich areas is mainly controlled by the fault fold or rupture. After studying the type of development and distribution characteristics of large medium sized gas fields of each second order structure in the foreland basins, the authors hold that the large scale structural traps in the lower block of thrust belt, the lithological fringe in the foreland slope area and shallow secondary gas pools as well as the fault block traps in the frontal uplifts of foreland basins etc. are favourable enrichment zones of natural gas in this kind of basin. On the basis of detail geologic research for the foreland basin and the present situation for natural gas exploration, the authors draw out the useful ways to select profitable exploration areas, and select five profitable gas rich areas in the foreland basins of Central and West China. They are large scale structural traps underneath the salt bed in the lower wall of over thrust fault in Keyi structural zone of Kuqa foreland thrust belt in Terim basin, Lenghu―Nanbaxian structural zone in the thrust belt on the northern fringe of the Qaidum basin, Jurrasic Yanjinggou Sumatou Longquanshan shallow gas beds of foreland sag in northwestern Sichuan basin, lithological fringe zone in Upper Triassic Xujiahe Formation on Zitong slope of Chuanxi front slope belt and Tertiary and Cretaceous gas reservoirs of second and third structures in the southern fringe of Jungar basin.
