摘　　要：新场构造带是川西坳陷内近东西向展布的较大型三级正向构造单元,其中发育孝泉、新场、合兴场、丰谷等次级构造,构造圈闭条件优越;该构造带的海相沉积雷口坡组—马鞍塘组发育碳酸盐岩滩相储层,雷口坡顶发育不整合面缝洞型储层;成藏匹配条件优越;川科1井已在孝泉构造马鞍塘组获得天然气突破,在雷口坡组见良好天然气显示。通过成藏条件综合研究和储层精细预测,提出了探井部署建议。With better structural trap conditions,Xinchang structural belt is an E-W-strike,large-scale three-level positive structural unit within West Sichuan Depression.Some substructures are developed in it,including Xiaoquan,Xinchang,Hexinchang and Fenggu.In this structural belt,carbonate rock shoal reservoirs are developed at marine Leikoupo and Maantang formations;unconformity fracture-vug reservoirs are developed in top Leikoupo Formation;and there are better reservoir-forming conditions.In addition,gas breakthrough has been obtained from Maantang Formation in Chuanke 1 well of Xiaoquan substructure whereas better gas show may also be found in Leikoupo Formation.At last,some exploration suggestions are made based on analysis of reservoir-forming conditions and fine prediction of reservoir.
