MARLSTONE IDENTIFICATION IN REEF FLAT FACIES RESERVOIRS IN NORTHEASTERN SICHUAN BASIN
摘要
Abstract
Reef flat facies reservoirs have been widely developed in Changxing Formation and Feixianguan Formation in Northeastern Sichuan basin. A group of tidal flat dolomite with different thickness develops in top Changxing Formation, and a group of marlstone sediments develops at the bottom of Member I of Feixianguan Formation, with thickness is closely related to that of tidal flat dolomite in Changxing Formation. Marlstone source rock has features of little thickness and low wave impedance inversion. To avoid the mistake that taking marlstone as reservoir, this paper analyzes on logging response and seismic response characteristics. Based on logging analysis and deposi tional environment of marlstone, it presents an idea of identifying marlstone in reef flat facie reservoir, combined with multi-attribute and high-resolution nonlinear parametric inversion, seismic acoustic impedance inversion, crossplot technique, as well as analysis on sedimentary facies and seismic facies, Research and application of real data proves its effectiveness in indentifying marlstone with reservoir characteristics.关键词
