A new idea for lithologic trap description with little wells: Taking Liaodongwan area as an example
Online published: 2009-12-16
Lithologic reservoir of gravity flow deposits are an important exploration target of fault-controlled lake basins. Exploration is difficult for the conversion of object, such as play choice, trap identification and description. Now petroleum geologists often pay attention to trap identification, but systemic study of formation mechanismand inner composition （specially not typical submarine fan deposits） are ignored. This paper first introduces the conception of lithologic trap description with the content of lithologic trap. It links geological dynamic analysis and geophysical static escription, and figures out the problemof play choice, trap identificationand description according to formation mechanism, development model and inner composition of fault-controlled lake basins. Then authors expound the main study methods and techniques. Exploration practice proves that the conception, method and technique are effective for lithologic trap and will promote the exploration of lithologic reservoirs.
