On April 22, according to the international famous oil AAPG and SEG in Barcelona, Spain, jointly organized the 2016 international conference on, tarim oil field scientific research "in kuqa foreland thrust belt salt under ultra deep oversize sandstone gas fields found and theory of technology innovation" is the house of geological evaluation at home and abroad as one of the important achievements in the field of oil and gas exploration in the world in recent years.

Kuqa piedmont natural gas exploration in tarim basin is the main. Geological experts for its complexity, described: deep like a spring, wheeled high belt, trap hide-and-seek, called DeZhiJie goldbach conjecture. Because the foreland thrust belt in the ultra deep oil and gas exploration at home and abroad there is no mature theory technology can draw lessons from, target identification is difficult.

Since 2005, pioneering the tarim oilfield tectonic modeling research related to foreland basin salt in salt foreland basin are found on the "salt, gypsum, salt under" special geological regularity of hierarchical contraction deformation, for the first time to establish "canopy structure on the salt, salt under thrust imbricated" geological theory knowledge, for g deep rich expected findings laid a solid foundation.

Engineering and technical breakthrough, kuqa salt under deep oil and gas exploration and discovery. Based on prestack depth migration processing requirements, research and development of mountainous region wide azimuth 3-d seismic acquisition techniques such as higher density, the implementation of large area mountain 3 d seismic, first-grade product rate of raw material increased from 60% to 60% above, revealed deep 2 g salt, such as large structure under the mysterious veil. At the same time, independent research and development supporting form is suitable for the kuqa foreland thrust belt in the ultra deep, thick composite salt layer, multiple pressure systems of tower marking Ⅱ series of well bore structure, meet the reservoir reconstruction, multiple sets of composite salt layer drilling demand conditions; Integrated innovation form represented by vertical + efficient PDC bit drilling ultra deep well drilling speed, achieve a new breakthrough in prospecting.

In recent years, the petroleum geology theory innovation, guide the kuqa foreland thrust belt in the buried depth of more than 7000 meters deep 13 large and medium-sized triple reserves have been found over trillions of cubic meters of large gas fields.
