The status quo,experience and strategy of hydrocarbon exploration in Tarim basin

Chai Guilin  
The area of Tarim basin is about 0.6 million km~2.The mid part of the basin is Takelamagan desert,which covers the area of 0.33 mi- llion km~2.The hydrocarbon exploration in the basin began in early 1950s.The exploration results after 1983 make people have the know- ledge of hydrocarbon resources in the basin:the basin has the geologi- cal framework of three rises and four depressions;differential block- faulting controlled hydrocarbon distribution;Palaeozoic group is the major target sedimentary-series,where there are geological conditions to form huge hydrocarbon accumulations;the platform-type rise around north depression is the favourable area where big oil and gas fields can be discovered.In recent years,drillings were conducted in the north part of the basin,and rich industrial oil flows have been obtained respectively in Cambrian-Ordovician,Triassic and Jurassic systems. These achievements are due to the performance of reasonable areal exp- loration,right exploration target,advanced geophysical exploration, emphatic comprehensive study and serious well testing. In the years to come,we should formulate reasonable and effective exploration deployment on the basis of favourable conditions in this area; speed up geophysical exploration,especially seismic exploration; widely apply new techniques and make full use of various geophy- sical informations; have deep comprehensive study; make a concentrated exploration on Tabei rise so as to create oil production as fast as possible; make reconnaissance of the central rise in order to gain new leap in oil exploration.
