Abstract

Abstract: Cambrian Fujunshan Formation inside the buried hills in Jizhong depression was investigated to the structure, lithofacies palaeogeography, reservoirs, caprocks, hydrocarbon sources and traps using drilling, seismic, well test and laboratory data. The study results show that Cambrian Fujunshan Formation includes good dolomite reservoirs, and two sections of stable and effective caprocks (Cambrian Mantou Formation and Xuzhuang Formation; Qingbaikou mudstone), which constitute the most favorable reservoir-caprock-isolator assemblage; There are five types of hydrocarbon transport systems:vertical hydrocarbon migration from deep source along faults, lateral hydrocarbon migration from near source along faults, hydrocarbon migration inside source along unconformity, hydrocarbon migration along faults and unconformity, and step-like hydrocarbon migration along fault and effective reservoir; 4 types of traps developed:layered fault trap, bedding unconformity slope trap, adverse unconformity slope trap, and fault-unconformity trap. It is concluded that favorable reservoir-transport system-caprock configuration (isolator) is a key factor for hydrocarbon accumulation inside buried hills. Finally, 3 class I and 2 class Ⅱ exploration zone are proposed, and several buried hill belts are selected for future exploration, including Hexiwu buried hill belt, Wen'an slope west buried hill belt, Nanmazhuang buried hill belt and Changyangdian buried hill belt.

Key words: Jizhong depression, inside buried hill, Fujunshan Formation, accumulation conditions, reservoir-caprock assemblage, exploration direction
