本次研究利用测井资料合成地震记录对地震反射层位进行标定,以此为基础对雷气1块的构造进行精细解释,落实沙三段含气砂体的构造形态,砂岩分布范围,对有利圈闭进行评价。研究结果表明:雷气1块及其周边地区断裂不发育,构造形态比较简单,只发现和落实了雷气1断裂背斜构造和高33断裂鼻状构造两个局部圈闭。通过对油源条件、储集条件和勘探效果综合分析认为,该块具备优越的油气成藏条件,为本区下步钻探部署提供了有利的基础资料。
In this study, the seismic reflection horizon was calibrated by synthetic seismogram recorded by well logging data. Based on this, the structure of gas-levee 1 block was finely interpreted, and the tectonic morphology and sandstone distribution of gas-bearing sand body in the third member of the sandstones were fulfilled. Favorable trap for evaluation. The results show that the rupture of Block 1 and its surrounding area is not well developed and its tectonic morphology is relatively simple. Only two local traps, ie, Leifeng 1 fault anticline and the nose structure of Gao 33 fault, have been discovered and implemented. Based on the comprehensive analysis of oil source conditions, reservoir conditions and exploration results, the block possesses favorable hydrocarbon accumulation conditions and provides favorable basic data for the next drilling deployment in this area.
