The formation of the hydrocarbon resources in China, may be the future of oil and gas exploration and development of land of hope.
In 1922, a professor at Stanford university in the China and Siberian oil resources in China, said: "lack of oil to three geological conditions: the mesozoic-cenozoic no Marine deposits Paleozoic strata do not produce; most of the oil; in addition to the west and northwest some areas outside, almost all of the geological era rock are after strong drape, fracture and the invasion of the different degree by igneous rock. As a result, China no more Marine oil."
-Good spoken written-spending.ne exactly have oil? Marine oil in where? Our answer is: the formation of the Marine world have not only, and oil is very rich.
Our country the Paleozoic Marine sediments distribution is very extensive, in north China and south China, the tarim, and develop best junggar plot.
DuoNian 40 before, geologists will doubt, China's oil fields are found in the new generation is, in our country, is the formation of no oil? In the U.S., 56% of the oil field, which contains in the Soviet union "the second Paleozoic Baku" (volga-oil-gas) which contains in the urals and the devonian, Algeria, Liberia, large oil field, belong to the palaeozoic reservoir. Is our country the cover of Paleozoic gently, drape moderate area no hydrocarbon accumulation conditions? In this line of thinking, in 1970, we came to the tarim basin, the author put forward the Permian basin-the tarim basin is an important food born of porosity of oil and gas. In 1978, we have put forward Cambrian conodont-ordovician is the important petroleum basin of porosity is born. In order to confirm the inference and judgement, in 1984, we in the northern uplift the structure of sand yakela deployed straight ladybell 2 well. The well to the drilling of ordovician dolostone, have a strong, has high yield YouQiLiu blowout, realize the Paleozoic Marine oil and gas in our country the major breakthrough.
China's oil Wells is 2 straight ladybell is a significant milestone in the history of natural gas KanTanShi. After that, we again in tarim basin DuoGe found the formation of continuous gas fields. With the first a deep Paleozoic oil field-tahe oil field was born in China, and dumped "China Paleozoic Marine oil free theory" of the hat.
Since 1984, our country in the Paleozoic Marine were found dozens of oil and gas fields, including a large oil and gas field 14. Oil and gas found in China in recent years in the formation of the Marine oil and gas more than in oil and gas, natural gas Cenozoic continental found more than oil found characteristic.
After four times the national range of oil and gas resources evaluation, China's oil resources total to 108.6 billion tons, geological natural gas for 56 trillion cubic meters. This geological resources just at present research degree and oil and gas exploration degree relatively low case calculated from the earth, physics point of view, it can't represent China in the actual oil and gas resources reserves. Once four oil and gas resources evaluation situation, many basin hydrocarbon resources is also a higher than a. Such as oil and gas resources in tarim basin, the first (1985) for 6 billion tons of oil equivalent, the second (1995) for 12 billion tons of oil equivalent, and by the third (2005), the increase to 15 billion tons of oil equivalent.
The formation of oil and gas exploration will become our country land of hope.
This kind of judgment based on the fact that, first of all, from oil and gas resources evaluation results look, at present our country the formation of oil and gas resources geological reserves of 36 billion tons of oil equivalent, its proven rate is only 8.7%, resources conversion is only 10%, and there are vast regions of the formation of the basically not been carried out exploration work; Then, from the geological evolution in our country, we can see the Paleozoic structure after many spinning back evolutionary history, not only makes the prototype basin, and has formed a large inheritance uplift and slope for big oil and gas fields, form laid the foundation; Third, from gas combination conditions look, China's four major plot the formation of reservoir development, have many good times, multi-layer section features.
Based on the above analysis, the future of oil and gas exploration in China, the development trend from the formation of new should be to the transfer from the east to the west, transfer, and from the land and sea, from oil to gas transfer (including coalbed methane, shale gas) transfer, from which to transfer, deep in the shallow layer to the basin from zones transfer.
