应用探边测试方法对断块油气藏进行早期评价

Application of Prospecting Boundary Method to Early Time Estimation for a Block Oil Gas Reservoir

本文叙述了探边测试方法的原理，介绍了高精度电子压力计系统探边测试在大港油田唐北地区断块油气藏早期评价中的应用。通过探达测试取得了可靠的油气藏动态资料，计算的储量面积、边界距离和形状等参数与实际情况相吻合，证实了此种方法是滚动勘探开发断块油气田的一种重要手段。经过静态与动态资料的综合分析，修改了地质构造图。经过再次优选规化井位，避免了钻落空井和低效井11口，节约钻井投资两千多万元。

This paper describes the theory of prospecting boundary method,and pnantes application of prospecting boundary by high-accuracy electronic pressure gauge system which is applied to early time estimation for a block oil and gas reservoir in Tangbei district of Dagang Oilfield. By means of this method, such reliable dynarnic information of oil and gas reservoir as calculated parameters, reserves in-place and oil bearing area,location and shape of boundary which is identical to real situation is Obtained. This work altered previous disadvantgaeous condition which depended on static data to estimate early time oil and gas reservoir. By interating static with dynarnic analysis,modifying geological map. Well locations are selected and planned again,11 empty and/or low effective well to be drilled are avoided, saved drilling cost more than 20 million yuans.
