摘要
为使VSP井下油气层测井仪在工作中保持稳定,保证测试结果的准确性,根据VSP测井仪的实际结构建立了机构简图,并建立了与该机构相对应的数学模型,利用MATLAB软件编制程序,得出了合理的水平推力和间距长度,提高了推靠机构的稳定性及VSP测井仪的测试精度。
VSP jogging tool was used to test the oil gas reservoir, the correctness of testing result was decided by its steady working. The reasonable size of eccentering machinery should be chosen for making VSP jogging tool work steadily. The eccentering machinery was simplified, and then the mathematics model was constructed. The calculation result was obtained using MATLAB. The reasonable horizontal pushing force was 6000 N and the reasonable length of AB was 40 mm. The measuring precious of VSP jogging tool was improved, the cost was decreased.
