摘要

油藏流体连通性分析已成为石油开发地质学中的一项重要内容,油藏流体连通性的好坏,不仅关系到生产井位的部署和射孔的层段,而且关系到注水井的部署及注水效果等。主要用原油气相色谱指纹相关性和紫外光谱技术来阐述油藏流体在纵、横向上的连通性。S1 - 2 6- 1井在浅层射孔( 30 5 m)发现工业油流。以前浅层的试油结果表明仅有油显示,但没有工业油流,因此怀疑该井所产原油因油管泄漏而来自中深部。通过对该井油样及邻近油井的中浅层油样进行气相色谱指纹分析和紫外光谱分析,表明S1 - 2 6- 1井的原油来自浅层。

Abstract

It is importan to analyze the continuity of fluids in rese rvoirs in developemnt geology. The condition of the continuity of reservoirs is  relate to not only the location of production well and the perforated interval b ut also the location of input well and the efficiency of injection of water. The  techniques of the fignerprints of gas chromatograms and spectrophotometry have   been applied to the vertical and lateral continuity of the reservoirs. The indu strial scale oil was found by penetrating at shallow zone (305 m) in well S1-26 -1. The result of testing once at shallow zone suggested that there was merely  oil trace, not industrial scale oil. So it is doubted that the industrial scale  oil come from the mid-deep level because of the leaky casings. The results of s tudy on the continuity of oil between well S1-26-1 and near this well show tha t the oil of well S1-26-1 come from the shallow zone.
