Abstract: According to some implementations, the present disclosure relates to a methods and apparatus for evaluating exploitation value of a geological resource. In one implementation, a method includes: acquiring geological parameters of a geological structure in multiple designated dimensions, wherein the geological parameters are used for characterizing a state of the geological structure in the designated dimensions; matching the geological parameters with a threshold of each of the designated dimensions, respectively, to obtain a characterization value of each of the designated dimensions; forming a characterization vector from the characterization values of the designated dimensions; and performing an evaluation operation based on the characterization vector to obtain an evaluation value of the geological resource in the geological structure. The exploitation value of a geological resource can be evaluated by taking the effect of a threshold of the geological resource on the exploitation value of the geological resource into full consideration.

Abstract: The present disclosure provides a method and a catalyst for selective oligomerization of ethylene. The raw material for the catalyst consists of a dehydropyridine annulene-type ligand, a transition metal compound, and an organometallic compound in a molar ratio of 1:0.5-100:0.1-5000. The present disclosure also provides a method for selective oligomerization of ethylene accomplished by using the above-mentioned catalyst. The catalyst for selective oligomerization of ethylene has high catalytic activity, high selectivity for the target products 1-hexene and 1-octene, and low selectivity for 1-butene and 1-C10+.
