用主曲率法研究裂缝性油气藏

RESEARCH ON THE MAIN CURVATURE METHOD AND ITS APPLICATION TO CRACKY OIL-GAS DEPOSITS

研究裂缝分布是油气勘探中一个很关键的环节。目前，工程实践中一直靠经验对裂缝分布下定性结论。本文通过对裂缝的形成因素、特征、以及裂缝性油藏分布的研究，给出刻划裂缝分布发育程度的数学方法主曲率方法。并应用该方法研究某地区的裂缝分布情况。所得结论与地质资料和测井资料完全吻合，为下一步探井部署提供有效、科学的指导。

The research on fracture spacing is a key stage in oil and gas exploration. Currently, in engineering practice, the nature of fracture spacing is determined by geologists' experience. But geologists can only estimate that there are possibly cracks and can't give us a clear-cut proposal. The authors propose a mathematical method—the Main Curvature Method from the research on the forming factor, characteristics of crack and oil-gas deposit spacing, and resolve the problem by programming. In this paper, the authors analyze the crack spacing of the Damian pu-Luodai area and think that the conclusion is complectly identical to actual conditions. Accoridng to geologists, common opinion, the results can guide the next arrangement of oil well exploration.
