Background
The structural diagram of the exploration target layer is a basic diagram piece for determining structural development characteristics, realizing favorable drilling targets and finding out hydrocarbon reservoirs, particularly hydrocarbon source rock hydrocarbon discharge period, and directly influences trap formation time, hydrocarbon filling potential and exploration success rate. Before exploration and deployment, if the archaic structure diagram of the exploration target layer in hydrocarbon drainage period can be accurately compiled by means of seismic data, the success rate of exploratory wells can be greatly improved.
Currently, for exploration deployment, most researchers only perform trap identification and well position deployment according to the current construction diagram, and do not accurately characterize the ancient construction characteristics of an exploration target layer in a hydrocarbon discharge period, but one of key elements of a hydrocarbon-bearing structure, namely, the matching relationship between the construction trap formation time and the hydrocarbon discharge period, only if the construction trap formation time is earlier than or approximately equal to the hydrocarbon discharge period, a large amount of oil and gas can be captured, and the hydrocarbon-bearing structure can be formed. If late formation development or late formation reversal exists in the investigation region, a formation trap on the present-day formation map may form after the hydrocarbon discharge period, such a formation trap, although in good condition, is unable to capture hydrocarbon. Therefore, only according to the current construction diagram, the precedence relation between the formation time and the hydrocarbon discharge period of the construction trap cannot be accurately reflected, and therefore the drilling success rate of the construction trap in exploration deployment is not high.
Therefore, how to draw the archaic structure diagram of the exploration purpose layer in hydrocarbon discharge period is a problem to be solved.
