摘要

从断裂带附近流体性质出发, 深入分析了东濮凹陷兰聊断裂带流体活动特征及其成藏过程。综合分析原油和天然气物性、地层水矿化度、天然气成因类型、稀有气体氦同位素等在平面上和垂向上的变化特征, 充分说明了兰聊断裂带中的流体活动。分析认为, 深部石

炭、二叠系煤系地层生成的煤型气沿着兰聊断裂及其次生断裂系幕式充注至沙三段和沙二下亚段储层中, 在构造高部位形成聚集, 并与从杜寨断层或构造翼部运移上来的下第三系油型气发生混合形成混合气带, 不同成因类型的天然气呈明显的懜带状分布。

Abstract

Based on the flu id properties in the fau lt zone area, the
flu id flow character istics and pool - fo rm ing pro cess a long
Lanliao fault zone in Dongpu Depression are thorough ly
analyzed.W ith Synthetic analysis of the a lteration feature in
ve rtica l and ho rizontal o f crude o il and na tura l gas phy sica l
properties, forma tion w ater sa linity, natural gas genetic types
and helium - isotope, the flu id flow along Lan liao fault zone is
w e ll proved. The result show s that, the coal - form ed gas
genera ted from Carbon iferous - Perm ian coa l - bear ing
form ation flew a long Lanliao fault and its related fau lt system,
w hich ep isod ic charged into rese rvo irs o f the third m em ber
and low er second m em ber o f Shahejie Fo rm ation, and
accumu lated in the structura l h igh p lace. The coa l- form ed
gas m ix ed w ith o il- type gas generated from Eogene wh ich
m igrated from Duzhai fault and the structural lim b area, and
finally form ed a g irdle o f m ix ture gas. A s a result, gas o f
d ifferen t genetic types d istribute appa rently like a g ird le
